The basic meaning of the turnkey assembly is that the PCB is not completely assembled; Instead, the customer must compile it with the least amount of effort. The user provides only minimal information, and the PCB collector buys and collects all the parts, collects them to a greater extent and sends them to a partially unfinished customer, and the buyer completes the PCB.
This mounting model is used in many other products except PCBs. The simplest example we can find are children’s bicycles, most of which are sent to pieces, and the buyer only compiles the main parts. Similarly, cell phones are such packages. We can directly compare these two examples with PCB, small and important pieces of PCBs are compiled by the manufacturer and shipped to the customer. Then put all the parts and develop the product.
It is important to keep in mind that the parts that a client has to assemble is usually very easy to assemble. Now there is a turnkey PCB assembly, called the semi-key in the PCB assembly, in which the buyer also buys some of the material and the PCB maker does not do it all by itself.
A group of turnkey PCBs is always used to reduce costs. This is done so that the maximum equipment can be sealed in a smaller space so that the space and cost of the transport weight can be reduced. The cost of manufacturing all products in China is still below half the cost of production in the United States. PCB fabrication and assembly China is the most efficient solution for printed circuit board manufacturers.
