That is to say, in a specific storage environment, the quality of the goods must be able to continue to meet the requirements of the specification, and ensure that in the way of use, not because of storage time is too long and failure situation, this can
Blind buried through hole circuit board (HDI circuit board) PCB manufacturing three key
HDI board is one of the most precise PCB board, and its process is also more complex. The core steps include the formation of high precision printed circuit, the processing of micro through hole, the plating of surface and hole.

general solid insulation material is not easy to fill the dead corners, and where the need to be closely matched, such as high-voltage cables, transformers, small capacitors, can be filled with mineral oil, ethylene glycol and carbon chloride, as liquid i
There are several processes of sun block welding for PCB circuit boards
Sunblock welding process can be roughly divided into three operating procedures:The first step is exposure. The second step is developing. The third operation process repair board.

this method can be used for imaging inspection of the sealing quality of the packaged traditional IC or the densely assembled PCBA. There are two practical models of laser Scan (SLAM) and C-mode scan (C-SAM) on the market.
The causes and solutions of PCB board distortion in PCBA processing are analyzed
The measurement method is to dissolve the sample in hot alcohol with titanium phenol as an indicator, titration required potassium hydroxide milligram number, namely its acid value.
Why are ceramic PCBS so expensive? What's the difference with ordinary PCB
Ordinary PCB is usually made of copper foil and substrate bonding, and the main material of ceramic substrate is alumina, beryllium oxide, aluminum nitride and other metal oxide ceramics, the performance of the two is quite different.
