Aluminum substrate is a kind of metal-based copper clad laminate with good heat dissipation function, and it is the basic material of high-power power electronic circuit structure technology and interconnection technology. In PCB proofing, the single-sided aluminum substrate is generally composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer,…
1. Multilayer pcb circuit board is a kind of printed circuit board which is laminated and bonded by alternating conductive pattern layers and insulating materials. The number of conductive pattern layers is more than three, and the electrical interconnection between layers is realized through metallized holes. 2. Comparing the production processes of the two parties,…
PCBA board processing belongs to high-precision manufacturing and must comply with relevant actual operating rules. So, what are the precautions for PCBA board processing? 1. During electronic pcba processing, the surface to be soldered cannot be taken with bare hands, because the grease secreted by human hands will reduce solderability and easily lead to soldering…
