Reasons for blistering of multilayer circuit board
(1) Improper suppression leads to the accumulation of air, moisture and pollutants;
(2) In the process of pressing, due to insufficient heat, too short cycle, poor quality of semi cured sheet and inc
Some Important Properties of Semiconductors
Why does the resistivity of semiconductor go down with temperature ?
Between the conductor and semiconductor resistivity difference is due to the different density of charge carriers.
Electronic products should use PCB. PCB (printed circuit board) is used in almost all electronic products and is considered as the "mother of electronic system products".
In 1936, Austrian Paul Eisler first used printed circuit board in radio. In 1943, Americans mostly applied this technology to military radios. In 1948, the United States officially recognized that this invention can be used for commercial purposes. S
