FPC with components

The same as PCB using the copper foil as the conductor, the flexible printed circuit board can also SMT components. The min. SMT size in our factory is 0201 (depends on the material and structure). The common components size is 0402. The connectors are available to SMT as well; only require add a FR4 stiffener on the back.
Model : FPC with components
FPC features in light, thin, flexible, anti-interference, low electricity resistance etc.  Our capacity: single sided, double sided, multi-layers, rigid-flex etc.  Special assembly: Ferrite lamination, SMT assembly, silicon rubber keypad assembly. FPC can be applied to wearable device, 3C products, headlight, timer, LCD, etc.

Finish products testing

ICT (In Circuit Test): proceed testing for SMT components to make sure the components locations are correct.

FCT (Function Test): proceed testing after SMT, but need customer provide us the fixture or machine.
