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.
