D. Gute Qualität. Welcome all kinds OEM ODM PCB order!
Business Philosophy:
Mission: To become a leading PCB manufacture in China. Customer’ satisfaction is more important than profit. Keep good quality and on time delivery is essential to satisfy clients.
To do right the first time and do right every time.
Quality Control:
Our company is ISO 9001 ,TS16949 certificated and UL approved, all of PCB are manufacturing under a stable management.
Quality Policy:
Quality is commercial integrity 1% defect may brings 100% disaster for customer. Our management goad is to make client 100% satisfied. Offering perfect products is essential to satisfy clients.
We ensure:
We use good brand base material and solder mask
In order to increase the reliability and performance, we never use local and
unknown brand supplier.
Enough copper thickness inside hole
Since some of our customer has complained the problem of les copper, we have improved and pay more attention the copper thickness inside hole.
It’s important because we know if not have enough copper inside hole it will increase the risk of electrical continuity problems (blow hoes, out gassing, inner layer separation, barrel cracking)
We platted to 25 um on normal board.
No short or open circuit repair
Poor repair can actually lead to open circuits being supplied. Even a “good” repair has risk of failure under oad conditions (vibration etc.) leading to potential field failures.
If anything we can do help for you ,
welcome to contact us at any time!
