Advantages
a) High Tg170 material. Excellent thermal reliability and CAF resistance providing long-term reliability for industrial and automobile application.
b) Electroless nickel immersion gold. Excellent surface planarity, particularly helpful for PCBs with BGA packages or even CSP mounted components to reduce failure rate during assembly and soldering.
c) Meeting your printed circuit board needs from PCB prototyping to mass volume production.
d) DDU Door to door shipment with competitive shipping cost.

PCB knowledge: Edge connector(Gold finger)
In order to ease the insertion of the PCB into the receptacle, the edge along the connector should be chamfered or beveled. The beveling angle can be 20°, 30° and 45°, tolerance +/-5°.
?
Bevel depth (L)

Calculation Formula of Bevel Depth:
L= (D/2-T/2)*tg a

FAQ
How do you pack the PCBs?
PCBs are packed with Polyethylene air cushion film(vacuum plastic bags) per 20-25 pieces. Pearl cotton (Polyethylene foamed sheet) are put inside carton box.
The hardness of carton box is KK grade(the highest hardness). Maximum gross weight for one carton is less than 12 kgs.
