Application range:

PCB hole drilling with higher hole accuracy

Small diameter PCB drilled hole with a diameter of 0.2 to 0.35 mm

High-layer board and difficult processing board

Advantages of coated aluminum sheet:

Improve hole accuracy

Reduce the incidence of broken needles

Has a good buffer

Improve hole wall roughness

Better heat dissipation, smoothness and lubricity

Laminate aluminum sheet characteristics:

1. The coated aluminum sheet is composed of non-polluting carrier and polymer lubricating epoxy;

2. The heat-dissipating lubricating layer is the main functional layer of the coated aluminum sheet, which is composed of a low melting point lubricating resin to achieve a cooling and lubricating effect; the same as 3. the lifting position accuracy of the drilling hole and the wear of the drilling needle itself are reduced;
