Leadfree Turnkey PCB Electronics Immersion Gold 1.6mm PCBA Circuit Board Assembly PCB Components Assembly
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 Advantages
1. Send your request to sales@sky-win.com.cn for a quotation. For
PCB assembly work, please send us:
PCB Gerber Files(RS-274X), and the specs such as color/ pads
finish/ layers, etc.
BOM Files, some reference links, or Digikey/ Farnell parts number
would be helpful for our quotation. Check the 5 Tips In BOM When
Asking PCB Assembly Price Estimate.
Files for the Soldering such as parts mapping for the pick-n-place
machine, or a simple mapping for hand soldering. (Check 5 Common
Problems In PCBA Manual Soldering if you have trouble in hand
soldering.)
Programming/ Testing Method, if you need Makerfabs to help on the
IC programming, or you want functional testing, send your related
guide and files to us, Sky-win will help to program/ test all the
PCBA boards to ensure you 100% pass.
Other Files that you want us to know to avoid mistakes in the whole
PCBA production process.
2. Sky-win appoint one project manager to customer, will make the
PCBA quotation in 1 working day.
3. Customers checking on the quotation and confirmation, and
negotiation if needed. For the PCBA cost, normally there will be 4
parts: PCB cost; components fee; assembly fee; others costs, such
as testing/ programming/ shipping, or other customized services.
Refer to How To Check The PCBA Quote From Shenzhen PCBA Factory.
4. Sky-win works on your project and PCBA in manufacturing.
Normally the lead time 2~4 weeks.
5. Packing and shipping, customer’s checking and feedback, then
projects closed if all OK.
