Turnkey PCB Materials
There're many kinds of PCBs, vary from the board materials, mainly:
FR4: The most commonly used Material for PCB.
FPC: Flexible Printed Circuit Board(or flex PCB) is a thin insulating polymer film that conductive circuit patterns are printed on, the most advantage for the FPC board is flexibility, which allows it to be the connection within a compact space or parts that need to bent. Also check the differences between Rigid-flex PCB and Flex PCB with stiffener.
Aluminum Board: The Aluminum PCB has good heat dissipation than FR4 PCB, which makes it suitable for boards that need quick/large heat dissipation, such as the LED Boards.
Rogers: When advanced electrical properties and performance are critical, such as Dielectric, dielectric constant, Rogers PCB boards would be the solution, normally only for professional high-frequency electronic engineers.

Turnkey PCB Assembly Testing & Quality Control
With more than 9 years' experience in PCBA manufacturing, Sky-Win treat quality as the most important factor in our business, to ensure the final boards quality, Sky-Win acts strictly as quality control as:
PCB Production: All PCB circuit boards are E-tested after fabrication; for mass production, we may test them with the testing fixture(testing jig).
Components: Sky-Win cooperated with the official components distributor, or Mouser/ Digikey/ Farnell, to avoid bad/ fate components. For electronic components that substitute brands will be used, normally for resistors/ capacitors/ connectors, Sky-Win will mark them in the PCBA quotation sheet, let customers know the detailed components used. Check the article How Sky-Win Source the Components for PCBA.
All components will be double tested before the soldering, surface mounting assembly, and through-hole assembly.
DFM and Prototyping: Sky-Win engineers will check every single project DFM(Design for Manufacturability) and notify the customer if any modification needed. Before the PCBA mass production, golden samples will be produced and tested. Mass production will be only done after the sample was confirmed by customers.
100% Visual Inspection: For prototype PCB assembly quantity >100 pcs, AOI(Automated Optical Inspection) inspection, according to IPC-A-610E and GB2828 sampling standard.
Programming & Functional Testing.Sky-Win provide fully functional testing to ensure all the circuit boards work perfectly as hand to the customer. Our engineers will program/ test all the assembled boards, as the customer's testing requests/ methods.
