Flex PCB Assembly

One-stop solution from flexible PCB Manufacturing to flex circuit assembly. We have good method to assemble flex PCB.

FPC is a flexible printed circuit. The printed circuit board assembly (PCBA) and welding process for FPCs (Flex PCB Assembly or Flex Circuit Assembly) are very different from the welding process for rigid PCB boards. Flex PCB is flexible because of its lack of hardness. If you do not use a special carrier board, it can not be fixed and transmitted; In addition, basic surface mount technology (SMT) processes such as printing, placement, and reflow furnace procedures could not be completed.

Fastlink manufactures 1 –12 layer flex PCB, and also provides flex PCB assembly service, full/partial BOM list procurement, and final flex PCB testing send your flex PCB file and BOM list to get a quote now.

Special Features of FastLink's Flexible Circuit Assembly

Save time: Assembly time is short

All lines are configured to save the connection work of redundant lines;

Small: smaller than PCB

It can effectively reduce the volume of the product, and increase the convenience of carrying;

Light: lighter than PCB (hardboard)

It can reduce the weight of the final product;

Thin: thinner than ChinaPCB

It can improve flexibility and strengthen the assembly of three dimensions in a limited space.

HOW DOES FLEX PCB ASSEMBLY WORK？

FPC fixation

FPC should be fixed on the carrier plate with thin and light high temperature resistant single-side adhesive to avoid FPC deviation and warping. The adhesive tape should be moderate to facilitate peeling after reflow welding and leave no adhesive on FPC.

Solder paste printing of FPC

Solder paste should have excellent thixotropy, solder paste should be able to easily print release and firmly adhere to the FPC surface, there will be no bad release-blocking mesh leakage or collapse after printing.

Because the temperature uniformity of FPC is not good, it is best to adjust the furnace temperature to the lower limit of solder paste technical requirements. The wind speed of a back welding furnace generally adopts the lowest wind speed that the furnace can use. The chain stability of the back welding furnace is better, and there can be no jitter.

FPC inspection, testing and sub-board

Before the test, separate the plate first, make special FPC punching and pressing die, stamping and cutting, can cut out the edge of FPC neat and improve the production efficiency.

As one of flex pcb assembly manufacturers, we can offer kinds of pcb fab and assemblyfor sale, if you have needs, please contact us.
