Turnkey PCB Assembly = turnkey Printed Circuit Board Assembly, which means turnkey service for PCB Assembly job. Customer no need to care anything but to send all files to us. Zhongfeng would manufacture the rigid PCB boards follow the design file, source the components follow the BOM file and do the PCB assembly job follow the assembly drawing and the pick&place file. After PCB assembly done, the components would be mounted on the PCB boards tightly and connected each other through the copper circuits. We call such board as PCBA board or rigid custom PCBA board.
Depends on the components assembly types, it have THT PCB assembly, SMT PCB Assembly , one sided SMT and THT PCB assembly, two sided SMT and THT PCB assembly.
Depends on the PCB type, it have Rigid PCB Assembly, Flex PCB Assembly and Flex-Rigid PCB Assembly.
Also we would call some PCB assembly types as Prototype PCB Assembly, Mass PCB Assembly , Turnkey PCB assembly, LED PCB Assembly and BGA PCB Assembly , etc.
With our 15years professional experience, we are available for all types of PCB assembly service from prototype to mass production, available for 01005, 0201, 0.3mm BGA, 0.3mm QFP.
