6-layer Thick Copper Through Hole Circuit Board Pcb&pcba
Description:
Thick copper pcb is a layer of copper foil bonded on the glass epoxy substrate of the printed circuit board, when the copper thickness is ≥2oz, it is defined as a thick copper plate. In PCB proofing, the thick copper plate belongs to a special process, which has a certain technical threshold and operation difficulty, and the cost is relatively expensive.
Application fields of thick copper circuit board: mobile phone, microwave, aerospace, satellite communication, network base station, hybrid integrated circuit, power supply high-power circuit and other high-tech fields.
Performance of thick copper plate: Thick copper plate has the characteristics of carrying large current, reducing thermal strain, and good heat dissipation. Not limited by the processing temperature, oxygen blowing can be used at high melting point, and the hot melt welding method such as constant brittleness at low temperature, and it is also fireproof, belonging to non-combustible materials. Even in corrosive atmospheric environments, the copper sheet will form a strong protective layer.
