Aluminium sheet for PCB product

Aluminium sheet for PCB product  specification
Application scope of coated aluminum entry board

•As coated aluminum sheet can effectively promote drilling precision, this product is widely applied for PCB drilling with high precision of hole site. It’s mainly produced for the PCB drilling with micro diameter at 0.1~0.4mm. Besides, coated aluminum sheet can promote precision of hole site and thickness of plate.
•It’s used for currently high-precision and high-density IC carrier plate (namely package substrate).

Usage of coated aluminum entry board

•Coating side is upward and aluminum side is downward on PCB;
•The height of drill point needs to be 1.5~4 times than its diameter for chip removal;
•Being pasted above base plate, drilling under drill point is the primary contact surface;
•Notice if tape is closely connected to cover plate;
•No fold or scratch is allowed on cover plate.
