FR4 Prototype PCB Assembly fine pitch QFN several connectors Min line width and space 1.0MM

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.
