BLACK Soldermask Turnkey PCB Assembly with ENIG finish and impedance control

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.

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.
