1.     What are the advantages of turnkey PCB assembly?

Shorter Lead Time

As a fundamental form of electronic assembly, PCB assembly primarily contains three phases: PCB fabrication, components procurement and PCB assembly. Traditionally, you should quote and confirm design files with sales and engineers working for your PCB manufacturer, then components distributors and finally PCB assemblers. Such series of quotations and confirmations just need your time spent in contacting with different partners. If those partners are from different countries, you have to overcome some problems such as time zone, communication habits etc.

Lower Cost

Another advantage of full-turnkey PCB assembly service is overall cost reduction. Pack-up service is usually cheaper than separate ones as far as electronic assembly is concerned. At least, freight fee will be saved because you don't need to get manufactured PCB boards and electronic components delivered to assembly workshop. Moreover, components procurement may get easy and customer-friendly because experienced electronic assemblers are usually able to provide reliable components with relatively low cost based on their long-term cooperation with parts manufacturers or distributors.

Transparent Monitoring

When it comes to electronic assembly process, it's significant yet difficult to monitor your products' manufacturing stage as it is totally related with your products' performance and time to market. Full-turnkey PCB assembly allows engineers at each stage to be aware of what they've accomplished and to better understand their status for better performance of final products.

2.     What is the process of turnkey PCB assembly?

You must be wondering what the turnkey PCB assembly process exactly is. Let’s see what are the steps involved in the turnkey PCB assembly.

Step 1: PCB Manufacturing

The first step starts when the client provides their circuit’s Gerber file. If you don’t have one, you can send the schematic and tell that what exactly do you have in your mind. They will create the Gerber file and start working on the PCB manufacturing process.

Step 2: Sourcing of Electronic Components

It is essential that the electronic components present on the PCB are of the best quality. There are many electronic components available in the market which claim to be genuine but bur out in a short period of time. Each component is checked for its reliability and then it is soldered on the printed circuit board.

Step 3: PCB Assembly and PCBA Tests

Once the circuit board is fabricated and the electronic components are sorted, the process of soldering starts. The right soldering technique together with high-quality solder paste and SMT stencils is crucial for high quality and fully functional PCB.

3.     What are the purposes of turnkey PCB assembly?

Circuit board assembly is a complex operation that requires the turnkey PCB provider to be equipped for the following tasks:

·  Outsourcing the fabrication of the raw printed circuit board and the construction of any necessary sub-assemblies to a network of business partners.

·  Parts procurement for both components and materials for the PCB assembly.

·  Manufacturing expertise to assemble all parts and subassemblies to the raw board fabs using various PCB manufacturing techniques.

·  Testing capabilities to verify the assembly of the circuit board.

·  Inspection equipment and processes for quality control.

·  Re-work stations to correct assembly errors or complete manual assembly as needed.

·  Shipping capacity to return the completed PCB assembly to the customer.
