: Board quality assurance needs to be considered

Everyone knows that the circuit board is to turn the designed schematic into a real PCB circuit board. Please don't underestimate the process. There are many things that work well in the project but it is difficult to achieve in the project, or others. Something that can be realized can not be achieved, so it is not difficult to say that it is a PCB board, but it is not an easy task to make a circuit board. The two difficulties in the field of microelectronics are the...

: What are the common faults in printed PCB boards?

The overall situation of China's copper processing industry is mainly as follows: the economic operation index is stable, the profit is slightly increased, and the overall profit rate of the industry is still low. However, compared with 2016, the debt ratio has decreased; the output has increased year by year, and the output of each sub-category has increased; Long-term net import, import substitution is slow. The strips, foils, rods and wires are all net imports, and copper ...

: Teach you how to choose an aluminum substrate?

The aluminum substrate aluminum substrate is a metal-based copper clad plate with good heat dissipation function. Generally, the single panel is composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. Also used for high-end use is designed as a double panel, the structure is circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. A very small number of applications are multi-layer boards...
