Quality Control Process

1. PCB Files Checking Before Production

For each order submitted, Gerber files will be reviewed by our professional engineers before being sent to production. Engineers will confirm the production feasibility in terms of tolerance constraints such as board edge clearance, drilling, pad spacing, impedance and routing. When the engineer finds a problem with the file or there is something that can be optimized, an EQ will be raised, and our customer service representative will get in touch with you, so as not to delay production.

2. Raw Material Guarantee

The quality of the raw materials determines durability and security of the finished products. Ensuring the high quality of raw materials is one of the most basic principles for JH PCBA to manufacture PCB boards. JH PCBA has been working with leading suppliers in the industry,and inspect materials according to international standards and customer requirements, such as Shengyi、KB (kingboard)、 Nanya、Rogers、 Arlon、Taconic、Japan TAIYO and China Guangxin high-performance solder mask ink.

1-Lamination

2-Lamination

After lamination, there will be slicing test (to confirm the thickness of the dielectric), thermal shock test (to confirm whether it is delaminated), and also copper foil adhesion test.

3-Lamination

After lamination, there will be slicing test (to confirm the thickness of the dielectric), thermal shock test (to confirm whether it is delaminated), and also copper foil adhesion test.
