The aluminum content of 1060 aluminum sheet coil is 99.6%, it is also called pure aluminum sheet plate. It has good elongation and tensile strength, and high plasticity, corrosion resistance, electrical conductivity and thermal conductivity; because of its good elongation and high thermal conductivity, coupled with Henan Chalco’s strict control of 1060 aluminum sheet coil performance, plate shape, thickness difference and surface quality requirements to ensure the quality of the finished product, it is widely used as PCB aluminum entry sheet.

4 The product features of 1060 PCB aluminum entry sheet
1) 1060 PCB aluminum entry sheet has good elongation and tensile strength characteristics;
2) 1060 PCB aluminum entry sheet has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity.
3) 1060 PCB aluminum entry sheet has good elongation and high thermal conductivity, which can quickly take away the heat generated during drilling, and at the same time, prevent instantaneous deformation when the drill bit is drilled, so that the accuracy of the drilling hole is maintained good, and prevent burrs from being produced on the face of the board.
5 The application of 1060 PCB aluminum entry sheet
1060 PCB aluminum entry sheet are also widely used in ordinary circuit board drilling.
