Customer Reviews
We've been using Yingstar for the past 8 months. We decided to move our PCB production from the US to Yingstar to get our costs down.

—— David Duncan--President – SET

I have no doubt about YingStar being our best production partner, last time we made 3000 units of our boards, only several pcs have some small issues.

EMS OEM pcba assembly for smart watch circuit board SMT PCB Assembly

 

 

 

 
For PCB Circuit Board manufacturing, Yingstar has been verified by SGS. The layer count of this PCB Circuit Board is 4 layers and it was made with Rogers board material with only 1.2 mm board thickness. And The minimum Line width and space of the PCB is 0.1 mm.
 

 

 

 

The 5 types PCB Assembly options we offer:

  • Prototype PCB Assembly
  • Low-Volume PCB Assembly
  • Consigned PCB Assembly
  • High Volume PCB Assembly
  • Fully Turnkey PCB Assembly

For full turn-key, we take care of the entire process, including PCB fabrication, procurement of components, SMD&THT assembly, continuous monitoring of quality and final assembly. Whereas for partial turn-key, the customer can provide the PCBs and certain components, and the remaining parts will be handled by us.we has modernized its PCB assembly services to offer a one-stop, turn-key PCB assembly service which includes parts, fabrication and assembly - reducing production costs while improving quality and convenience.

Testing Procedures

We totally understand that bad quality products will bring our customers hugh loss and will damge both ours and our customers reputation, so we perform multiple quality assurance procedures before shipping out any of our board to guarantee our quality.

These testing methods include:

· Visual Inspection,

· X-Ray Inspection,

· AOI Inspection(Automated Optical Inpector),

· ICT test (In-circuit test), and

· Functional test (test modules need to be supplied).

For Functional test, we just need customers provide us the testing instructions and testing softwares, then we will design the testing fixtures, programme the chips and test the boards as instructed. In such ways, all boards quality can be guaranteed before delivery.
