Single side PCBs
Double sided PCBs
Multi-layer PCBs
All of the other electronic components are mounted on the printed circuit boards(PCBs),which are the foundation.
PCBs have mechanical and electrical attributes,making them for ideal applications. Most PCB’s fabricated are rigid, roughly 90% of the PCB’s manufactured today are rigid boards.

confidential level.
Q5: What does customer need for a customized PCB order?
A5: When you place a PCB order, the customers need to provide Gerber or pcb file. If you do not have the file in
the correct fomat, you can send all the details related to the products.
Q7: Does you have an minimum order quantity?
A7: We accept order with as low as a quantity of 1 (piece or panel).
Q8:what is the difference between PCB, PCBA and FPC?
A8: PCB is bare board without any components.
PCBA is the PCB through SMT or plug-in processing, welding assembly on the PCB board required electronic components, such as IC, resistor, capacitor, crystal oscillator, transformer and other electronic components, after reflow oven high temperature heating, will form the mechanical connection between components and PCB board, thus forming PCBA.
FPC generally uses Pi as base material, which is flexible and can be bent and flexed at will .
