How to Design for Testability Improving PCB Manufacturability？
One of the tenets of an outdoor trip is to ensure that all gear has been used at least once in a practice setting. Few things are more embarrassing and potentially dangerous than taking brand-new equipment out without knowing how to operate it. A low-stakes dry run is the perfect opportunity to gain familiarity with tools before being thrust into a situation where a lack of knowledge could spell disaster—or at least ruin a weekend. If you want to order PCB product, please check and custom your order online. Manufacturers test electronics for the same reason a weekend warrior going camping checks all the items in their pack: to determine functionality at a point where adjustments are easiest to perform. However, the board’s solder joints must be thoroughly tested for acceptability while the parts operate to specification. Testing careful circuit board preparations during design becomes a design factor in its own right; often, testing is non exhaustive because the PCB fails to incorporate a design for testing (DFT) approach. This lack of comprehensive methodology misses assembly defects that percolate into the end product and ultimately shape customer satisfaction. To prevent problems like this, here are some design for testability guidelines to ensure your next PCB design is fully prepared for testing. Design for Testability Best Practices to Consider When Designing PCBsThe first step a contract manufacturer will take when reviewing a DFT implementation is to consult the included customer test specifications. From this information, a test method develops to meet the requirements. Although the test engineers can add to the test criteria if necessary, standard practice dictates that the customer provide as much information as possible to meet expectations. The contract manufacturer (CM) review process will mark the schematic with test and connection points as part of their test preparations while examining the layout. Including specific test points in the schematic is another good design practice to help the CM expedite the turnaround time. The design review combined with the test methodology will help determine the type of fixture needed and if any modifications to the design are warranted to increase the total fault coverage of the test procedures. This information then merges into a test instruction (TI) document accompanied by descriptions, illustrations, and expectations for the test technicians to use during testing. Incorporating Maximum Testability Into the LayoutWhen laying out the printed circuit board for testability in design, there are some important considerations to remember: ICT points must be on each design net for complete test coverage.These test points must have a 50 mil clearance to components and pads.These test points must also have a 100 mil clearance to the board’s edge.ICT can be conducted simultaneously on both sides of the board, but you should set this up with your CM in advance.Another critical aspect of testing a circuit board is the time on the bench for functional or measurement testing. Test procedures require adequate probe points for manual testing of essential circuitry. Whereas test points usually refer to in-circuit or flying probe testing, probe points are vias designed large enough to give a technician access with a probe, wire, or header pin to conduct manual testing. Your CM Aces PCB Testability ConcernsDesign for testability is another constraint to add to the pile on a design for manufacturing (DFM) PCB. Still, by providing a test specification to your CM along with noted test and probe points in the schematic and obeying the minimum spacing rules for test points in the layout, you will be well on your way to having a fully testable PCB. However, you can do something else that will also be helpful: consult early with your CM on your design. This way, you can get your questions answered and determine what they need to test your board best.Wanna know PCB knowledge? Check and read for more.

What Are the 5 Essential Effects of PCB Microvia in PCBA Process?
The standard mechanically drilled and plated via adheres to the aspect ratio, defined as the ratio of the drill depth to the via diameter. PCB Board thickness is unlikely to vary after the earliest stages of design due to the impact of impedance and system integration within the enclosure, locking the minimum through-hole diameter of the board to a tenth of the board’s thickness (the upper limit).If you want to order PCB product, please check and custom your order online. Via diameters that exceed a 10:1 aspect ratio are likely to encounter reliability issues due to incomplete barrel plating towards the center of the barrel: · The longer the barrel is relative to the diameter, the more likely the copper ions plate to the surface of the barrel closer to the hole opening.· As the via diameter shrinks, the flow rate of the plating solution restricts.· Poor plating in the barrel compromises the structural integrity of the via. As the board undergoes heating cycles during operation, materials expansion in the z-axis (that of the board’s thickness) causes a stress-strain matrix to develop due to a mismatch between the copper plating and surrounding (most commonly) epoxy-fiberglass substrate. An aspect ratio above 10:1 inhibits proper plating along the length of the barrel and the via is liable to experience an earlier-than-expected failure during its service life. Designers are in a quandary: how can the via diameter shrink if the board thickness constrains its lower boundary? The answer is to pass up through-hole interlayer connections entirely with a microvia. A microvia, as defined by IPC, is a drilled hole with an aspect ratio of 1:1 and a depth no deeper than ten mils (.25 mm). Microvias usually only span two, and very occasionally, three layers in a board’s stackup; “through-hole” connections for microvias require chaining consecutive microvias together in one of two arrangements: · Stacked microvias are similar in function to a traditional through-hole via, with the hole center of the microvias aligned in the z-axis. While more space-efficient, stacked microvias encounter more reliability issues.· Staggered microvias can be distributed anywhere throughout the planes of the board, provided there is an electrical connection (e.g., a trace) between them.· The Effect of Microvia Fabrication on the Overall PCBA Production· Microvias are just one type of via structure and can coexist alongside through-hole vias, but the fabrication process is more involved. Whereas through-hole drilling and plating are individual, consecutive steps that follow the fusion of the board’s layers during lamination, microvias require multiple iterations of drilling and plating. Microvia construction forces lamination to become a multi-stage procedure where microvias are drilled in the appropriate layer pairs before final lamination completes the physical stackup of the board. Microvias are further definable by their location in the finished layup: · Blind microvias have one opening on an outer layer of the board.· Buried microvias have no openings on either outer layer of the board, i.e., entirely buried within internal layers.· The drilling process itself also accommodates multiple fabrication modes. While mechanical drilling can still apply to microvia fabrication through controlled-depth drilling, laser drilling offers many benefits, primarily greater throughput on high-volume lots and smaller diameters. Moreover, since laser ablation is a non-contact drilling method, it is exempt from some of the defects common to mechanical drillings, such as drill wander, vibration, smear, and bit breakage, which can severely impact the final quality of the microvia. Do I Need Microvias? Analyzing Their Cost-Benefit For HDI boards, a designer should ask their manufacturer, “Are microvias the correct choice for my design?” There is some nuance here, but if a design cannot otherwise free up the space required for routing within the board’s dimensions, microvias are practically unavoidable. Layout designers should start constructing a rough board placement to understand routability and whether through-hole vias are suitable. An excellent starting point is assuaging the finest pitch component – typically a BGA – to determine the smallest possible via and what additional fabrication processes may be required (i.e., microvia or via-in-pad). Microvias are a cost adder to the fabrication process and create new reliability issues. Designers will want to assist manufacturing by considering some DFM constraints: · Design stackups containing microvias that require four or fewer lamination cycles. Additional lamination steps complicate fabrication and introduce more high-temperature/pressure stress that can undermine long-term reliability.· Each lamination step must plug buried microvias with epoxy to support reliability.· Multiple laminations reduce the registration of the drilled microvias, resulting in designs that drift in accuracy from their design documentation. While tolerances allow for some misregistration, an excessive amount is enough to disrupt board performance and functionality, leading to scrap.Wanna know PCB knowledge?

What Is Air Conditioning Pcb?-3 functions
Air conditioner PCB (Printed Circuit Board) is an essential component of air conditioning systems, playing a role in controlling device operations and the entire workflow. This article will provide a detailed overview of the structure and functions of air conditioner PCBs, their working principles, applications, manufacturing processes, and development trends. This will help in better understanding the role of this critical component and its future developments. Customize your air conditioner PCB, welcome to place an order on the PCBBUY website.1. Structure and Functions of Air Conditioner PCB: An air conditioner PCB mainly consists of circuit boards, electronic components, and connectors. Depending on the type of air conditioner, the structure of the PCB varies. Generally, air conditioner PCBs are divided into indoor unit PCBs and outdoor unit PCBs. The indoor unit PCB includes CPU control circuits, power circuits, signal driver circuits, airflow control circuits, and indoor fan control circuits. The outdoor unit PCB includes an outdoor conversion board, outdoor computer board, defrosting board, three-phase power phase sequence detection board, and power module board for outdoor inverter air conditioners. In addition, depending on the air conditioner's functions, auxiliary circuit boards may be installed on the air conditioner PCB, such as remote control reception and indicator circuit boards, and air conditioner circuit boards with displays. The main functions of the air conditioner PCB include: Control Function: Receives and processes external input signals such as temperature, humidity, and air quality. It controls the operation of the air conditioning equipment based on preset programs.Drive Function: Controls the compressor, fan, water pump, and other motors of the air conditioning equipment through the drive circuit, enabling cooling or heating functions.Protection Function: Monitors the operating status of the air conditioning equipment, such as voltage, current, temperature, etc. It automatically cuts off power or reduces equipment load in case of anomalies to ensure safety. 2. Working Principle of Air Conditioner PCB: The air conditioner PCB controls the device through circuit connections. Electronic components are laid out and connected on the circuit board according to specific circuit designs, forming a complete circuit system. When the air conditioning device is powered on, the PCB receives external input signals from temperature sensors, humidity sensors, etc., processes them, and outputs corresponding control signals. These control signals are transmitted to motors, compressors, and other actuators through connectors, driving them to operate according to the preset working mode. For example, when the indoor temperature exceeds the set value, the PCB receives the signal from the temperature sensor and outputs control signals to start the compressor and fan, reducing the indoor temperature. When the indoor temperature reaches the set value, the PCB outputs a stop signal to halt the operation of the compressor and fan. The air conditioner PCB is a core component of an air conditioner, and its working principle is based on receiving and transmitting signals to control and regulate various components of the air conditioner. After the air conditioner is powered on, the circuit board transmits the signal from the temperature controller to the internal controller. The internal controller then calls the components related to the air conditioner operation, such as the condenser, evaporator, and fan. Moreover, the internal controller transfers its signal to the circuit board, allowing the board to assess the air conditioner system's operational status by detecting signals like temperature, humidity, pressure, current, etc. If the air conditioner system experiences abnormalities such as high or low temperature, water leakage, etc., the circuit board promptly sends out warnings to remind users to address the issues in a timely manner, avoiding potential problems. Additionally, the air conditioner PCB boasts automatic control capabilities. For instance, it can automatically adjust the air conditioner's fan speed and temperature based on indoor temperature, enhancing comfort. Users can also set timers for automatic power on and off, providing convenience. The implementation of automatic control features lightens the user's operational burden and enhances the user experience. While the construction of an air conditioner PCB is quite complex, its primary function is to receive and transmit signals to control and regulate the operation of various air conditioner components. Furthermore, with the continuous advancement of technology, air conditioner PCBs are constantly being improved and upgraded, becoming more intelligent, efficient, and energy-saving. 3. Applications of Air Conditioner PCB: An air conditioner PCB is a crucial component for controlling and managing air conditioning equipment. It typically comprises multiple electrical components and connectors that transmit current and signals, enabling the proper functioning of air conditioning devices. The application of air conditioner PCBs is extensive. They are not only widely used in household air conditioners but also find applications in industrial, commercial, and specialized air conditioning systems. For example, in commercial buildings, central air conditioning systems consist of multiple indoor and outdoor units connected by air conditioner PCBs, allowing for centralized control and monitoring. In special environments such as mines, aerospace, ships, etc., air conditioner PCBs ensure efficient and stable operation of air conditioning equipment. 4. Manufacturing Process of Air Conditioner PCB: The manufacturing process of an air conditioner PCB mainly involves the following steps: Taking a double-sided PCB as an example, the production process can be roughly divided into the following points: MI Cutting: Based on the manufacturing instructions, large sheets of material are cut and trimmed into appropriate small pieces.Drilling: This is the first step in making the PCB. The board will have many holes of varying diameters. According to the requirements, holes are drilled in the cut sheets, including through holes, electrical holes, and mechanical holes.Copper Plating: Thin copper is deposited on the insulation hole wall of the board using chemical means to create a conductive paste, laying the foundation for the next step.Circuit Design: The circuit is divided into three steps: pressing the film, which attaches blue photosensitive film to both sides of the board; exposure, where the parts of the board with circuits are blackened using an automatic exposure machine; and development, where the exposed parts are developed to reveal the copper.Graphic Plating: This step thickens the exposed copper and tin on the bare PCB, and after that, a demasking agent is used. Then etching is performed. During etching, only the copper reacts, and it doesn't affect the tin. Finally, a tin demasking agent is used to remove the tin.AOI Optical Inspection: The semi-finished PCB is inspected using an optical inspection instrument to detect issues like shorts and open circuits. Problematic areas are refined promptly.Solder Mask: By this stage, the PCB is already a semi-finished product. The solder mask is applied to the board's surface to protect the copper, preventing oxidation due to copper exposure to oxygen, which could affect the PCB's performance and lifespan.Silk Screen Printing: According to customer requirements, relevant information such as codes, component names, and models are printed on the board.Surface Treatment: This can be gold plating or tin spraying. Gold plating results in a gold-colored board, while tin spraying results in a silver-colored board. Both methods prevent copper oxidation and facilitate later component soldering.Testing: After the above steps, the PCB takes shape. Subsequent testing is carried out manually and using electronic devices to assess whether the PCB's quality has any problems. 5. Development Trends of Air Conditioner PCB: With the advancement of technology and increasing consumer demand for energy efficiency and environmental protection, air conditioner PCBs are also continuously developing and upgrading. The future trends of air conditioner PCBs include: High Integration: By adopting more advanced manufacturing technology and electronic components, PCB integration and performance are enhanced, reducing size and weight, and lowering costs.Intelligence: Combining IoT technology and artificial intelligence, air conditioner PCBs achieve intelligent control and autonomous diagnosis, enhancing equipment efficiency and reliability.Environmental Sustainability: Using environmentally friendly materials and manufacturing processes reduces the environmental impact of PCBs while extending product lifecycles and recyclability.

What are Front-end Simulation and Evaluation in PCB Industry?
PCB simulations begin in the schematic capture phase of a design project, where SPICE simulations are used as part of circuit design. SPICE simulations are important for evaluating system-level electrical behavior, but they are also useful for circuit optimization as part of the design process. Schematic capture software with a built-in SPICE simulation package can help you stay productive while you work through some of the basic simulations needed to evaluate electrical behavior.If you want to order PCB product, please check and custom your order online. SPICE packages that are used for front-end engineering and simulations are designed to perform a specific set of analyses: · DC sweeps, where input DC voltage is swept through a series of values and the voltage and current at other nodes are monitored· Transient analysis, or time domain mixed-signal simulations; this is the fundamental time-domain simulation· AC sweeps, or frequency sweeps, where the frequency of an AC signal is varied in time· Parameter sweep, where a specific set of component parameters is swept across a range of values· Pole-zero analysis, where stability conditions and transient oscillation frequencies can be visualized in a single graph Some schematic capture programs with integrated SPICE engines can be used with more advanced simulations, such as noise analysis and thermal analysis. What are the common problems of circuit simulation in PCB manufacturing? While SPICE circuit simulators can tell you whether or not the circuit concept will work, the actual physical layout of the circuit still needs to be refined for the circuit board’s maximum performance. The circuit analysis for these refinements also used to require time-consuming and expensive testing of prototype circuit boards. However, design engineers can analyze from within the design tools while the board is still being laid out. ImpedanceImpedance analysis must be done before layout to determine the trace widths for the layer stackup of a circuit board. To control the impedance of high-speed transmission lines, it is essential to carefully calculate the board dielectric materials and width and the width and spacing of the traces. Some CAD tools also offer impedance checking during layout to confirm that the transmission line traces being routed are maintaining their target impedance values. Impedance analysis is important for combatting reflection and other signal integrity problems. High-speed timingDDR (Double-Data Rate) and other high-speed routing topologies depend on accurate trace lengths to support the timing requirements of their circuits for the best performance of the board. Many of these trace lengths also need to be matched to prevent one line from being faster than another, and the CAD tools will analyze the routing and report any problems. CrosstalkWhen a strong signal overpowers a weaker signal due to its proximity, it can result in the weaker signal mimicking its behavior instead of accomplishing its task. This condition is known as crosstalk, and it can create signal integrity problems that will degrade the board’s performance. Crosstalk analysis is an essential layout tool that designers should be acquainted with and regularly use. Return pathsThe clear return path of high-speed signals on the reference plane is another essential signal integrity check to minimize the amount of electromagnetic interference (EMI) the board is generating. Return path analysis tools can tell layout designers immediately if their boards will potentially generate too much noise. Power integrityWhen laying out a circuit board, it can be very easy to miss small details in the design, such as a power pin not having enough metal for a robust connection. Although there may be enough metal to pass the design rule check, in reality, there isn’t enough to support the amount of voltage that the pin will conduct. Power integrity analysis tools can give the designer immediate feedback during layout and determine which pins need a stronger connection to satisfy the power requirements. Design rule checksAlthough not considered an “analysis” tool, a designer should always check the layout’s basic design rules and constraints before sending it out for manufacturing. Circuit board fabricators and assemblers often find simple errors that should have been caught in design but weren’t because the rules were either not set up correctly or not used at all. Thankfully the design rules in today’s CAD systems are very comprehensive and often include a 3D display and checking for a complete object clearance verification.Wanna know PCB knowledge?

As part of the global shift of the PCB industry to Asia, China's mainland has attracted numerous investments from PCB enterprises due to its vast domestic market demand, relatively low labor costs, industrial policy support, and mature processing technology. On one hand, a significant number of foreign-funded enterprises have relocated or added production capacity in China's mainland. On the other hand, domestic-funded enterprises have accelerated capacity expansion. China's mainland has now become the world's largest PCB industry base, accounting for over 50% of the global market share. The sustained and healthy development of China's PCB industry has significant implications for the global PCB industry and the broader global electronic information industry. According to Prismark data, the annual average compound growth rate of China's mainland PCB output reached 5.60% during the years 2010 to 2019, significantly surpassing the global average growth rate. It is projected that from 2019 to 2024, the annual average compound growth rate of China's mainland PCB output will be around 4.88%, continuing to maintain a growth rate higher than the global average. Regional Structure Characteristics of Mainland China's PCB Industry China has established PCB industry clusters with the Pearl River Delta and Yangtze River Delta regions as the core areas. According to statistics from the China Printed Circuit Association (CPCA) in 2019, the PCB industry was distributed across 22 provinces and directly-administered municipalities in the country, with a total of 2,372 enterprises. Among them, Guangdong Province had 1,437 PCB enterprises, accounting for 60.58%; Jiangsu Province had 341 PCB enterprises, accounting for 14.38%; Zhejiang Province had 108 PCB enterprises, accounting for 4.55%. The combined number of PCB enterprises in Guangdong, Jiangsu, Zhejiang, Shanghai, Fujian, and other coastal areas accounted for over 84% of the total number of PCB production enterprises in the country. In recent years, as labor costs have risen and environmental requirements have become more stringent in coastal regions, some PCB enterprises have started to shift production capacity to provinces and cities in the central and western regions with better industrial conditions, such as Jiangxi, Hubei, Hunan, and Sichuan. In the future, it is possible that a collaborative development pattern may emerge among multiple regions, including the Pearl River Delta, Yangtze River Delta, Bohai Rim, and the central and western regions.
