We need to pay attention to the following five things when we manufacture thick copper PCB.
The difference between HDI PCB browning and blackening has the following two major points: 1. The similarities between HDI PCB browning and blackening. 2. The difference between HDI PCB browning and blackening.
In the thick copper plating process of thick copper PCB, the process parameters must be monitored frequently, which often causes unnecessary losses due to subjective and objective reasons.
We all know that there are many procedures for making HDI PCB from the planned feeding to the final step. One of the processes is called browning. Some people may ask what is the role of browning?
I believe everyone is no stranger to circuit boards. HDI PCB circuit boards have many colors, black, white, yellow, green, etc. Maybe many electronic enthusiasts will ask, why are HDI PCBs mostly green Woolen cloth? Then let us discuss this issue together!
1. The telephone is required to be easy to use after the components are installed, that is, the electrical connection must meet the requirements; 2. The line width, line thickness, and line distance of the HDI PCB circuit meet the requirements to prevent the circuit from heating, breaking, and short-circuiting; 3. The copper skin is not easy to fall off under high temperature;
