What Electronic Devices Can Be Used PCB in Manufacturing ?

By:PCBBUY 03/16/2023 14:49

Because so many different sectors use PCBs, you can find them almost everywhere in everything from small consumer devices to huge pieces of machinery. Where are printed circuit boards used? Here are 10 of the most common PCB applications by industry.


If you are curious about the information about electronic devices in PCB, please check and read the content below in this passage.

What are the common uses of electronic devices in PCB?


The healthcare sector is using growing numbers of PCBs as technologies advance, revealing new capabilities. PCBs play a role in devices used for diagnostics, monitoring, treatment and more.


Special attention must be paid to ensuring reliability when producing medical PCBs because proper functioning can be critical to patient health. In many cases, PCBs must also meet strict standards for sanitation, especially those used for implants. Boards used for implants and many other applications, such as emergency room monitors, must also be relatively small. Because of this, many medical PCBs are high-density interconnect, or HDI.


PCBs are used for medical devices such as:


·  Medical imaging systems: CT, CAT and ultrasonic scanners often use PCBs, as do the computers that compile and analyze these images.

·  Monitors: Heart rate, blood pressure, blood glucose monitors and more depend on electronic components to obtain accurate readings.

·  Infusion pumps: Infusion pumps, such as insulin and patient-controlled analgesia pumps, deliver precise amounts of a fluid to a patient. PCBs help ensure these products function reliably and accurately.

·  The medical sector is continually coming up with more uses for electronics. As technology improves and smaller, denser, more reliable boards become possible, PCBs will play an increasingly important role in healthcare.


What are the types of electronic devices in PCB?


Electronic devices can be divided into two major kinds: Passive and Active devices based on their functionality.


Passive devices

Generally, resistors, capacitors, inductors, are specified as passive devices.



The resistor is a passive electrical component whose function is to introduce resistance to the flow of electric current in an electrical circuit to limit the current. The magnitude of the opposition to the flow of current is called the resistance of the resistor. A larger resistance value indicates a greater opposition to current flow. The resistance is measured in ohms (Ω), and its equation is as follows.



The voltage (V), current (I), and resistance (R) are related by Ohm’s law. i.e. V = IR. The higher the resistance R, the lower is the current I for a given voltage V across it. It is a linear device. 


Different types of resistors by Size and Form


·  Through-hole resistors

·  Surface-mount resistors SMD/SMT.

·  Different types of resistors by Application


Common resistor: used in current limiter, setting biases, voltage dividers, pull up, filtering, termination resistors, load resistors, etc.

·  Precision resistor for voltage feedback circuits, voltage references.

·  Current sense resistors

·  Power resistors

·  Resistor selection parameters


The function of transformers is to transfer electrical energy from one circuit to another, with an increase or decrease in voltage. You can say the voltage is being ‘transformed’. Similar to inductors, they consist of a soft iron core with at least two coils of wire wound around it – the primary coil, for the first, or source circuit, and the secondary coil for the circuit where energy is being transferred to. You may have seen large industrial transformers on telegraph poles; these step-down the voltage from overhead transmission lines, typically several hundred thousand volts, to the few hundred volts typically required for household use.
