How to Select the Best Turnkey PCB Assembly Manufacturers

PCB fabrication and assembly is a process that should be carefully handled by professionals. Some customers prefer a PCB assembly company to handle all aspects of PCB production. Therefore, these customers turn to turnkey PCB assemblers for help. Turnkey circuit board assemblers offer one-stop solution for all aspects of PCB manufacturing and assembly.

What is Turnkey PCB Assembly Service?

Turnkey PCB assembly service offers end-to-end solutions. This type of PCB assembly service performs all aspects of PCB fabrication and assembling. Generally, the word “turnkey” simply refers to a service or product that is ready for immediate use. Therefore, in the PCB world, a turnkey circuit board service means that the supplier takes care of all aspects of PCB production. This will include the procurement of components, PCB design, and PCB assembly.

Also, turnkey PCB services are suitable for most OEMs since they don’t want to source out various functions to several vendors. There are two types of turnkey PCB assembly services. These include full turnkey PCB assembly and partial turnkey PCB assembly.

What is full turnkey PCB assembly?

A full turnkey assembly means that the all aspects of PCB production are completely handled by the supplier. Also, this type of turnkey assembly requires more lead times than a partial turnkey circuit board. In this type of PCB assembly, customers will have to send their design files while the PCB manufacturer takes care of everything from there.

What is partial PCB assembly?

A partial turnkey PCB assembly allows a customer to source out some parts and components while the manufacturer sources out the rest. In this type of turnkey PCB assembly, the PCB manufacturer will need to seek the approval on the quality, prices, and availability of materials from the customer. In some cases, the customer will provide expensive parts like ICs, connectors, and more. Furthermore, assembly process is much faster in this type of PCB assembly.

Benefits of Turnkey PCB Assembly

Turnkey solutions have made some projects easier. Also, turnkey PCB solutions offer convenience for PCB users. The benefits of turnkey PCB service include:

Good component quality

In Turnkey circuit board assembly, parts and components procurement is always handled by professional assemblers. Their working relationship with suppliers and expertise in PCB manufacturing help them to get best-quality component quality. You may not know how to evaluate the quality of PCB parts and components. Therefore, allowing your assembler to procure components will save you a lot of stress.

Easier prototyping

Turnkey circuit board assemblers carry out prototypes for every stage involved in PCB production. Also, this assembly service helps to reduce the cost of prototyping. The PCB assembler takes care of all aspects of PCB production based on your specifications. Furthermore, you will get better products when you leave everything in your vendor’s care.

Reduced costs

Turnkey assembly solutions help to reduce total production cost. You can eliminate some expenses since the service is always packed-up. One of the aspects where you enjoy cost reduction is in freight costs. You won’t have to spend money on moving the components from different sources to the workshop. Furthermore, it is easier to procure components since turnkey PCB assemblers can secure better deals with component suppliers.

Faster turnaround time

Imagine the time you would spend when you different people handle all stages of your PCB assembly separately. It takes a longer time to produce circuit boards when different companies are involved in their production. However, full turnkey circuit board assembly carries out all the stages of PCB production. Furthermore, this assembly minimizes the number of quotations and communications. In the long run, this minimizes the risk of project distortion.
