PCB inofanira kunge isingadziviriri moto uye haigoni kupisa pane imwe tembiricha, kungopfava. Iyo tembiricha yenzvimbo panguva ino inonzi tembiricha yegirazi (TG point), ine hukama nekukura kugadzikana kwePCB.

Ndezvipi zvakakwirira TG PCB uye zvakanakira kushandisa yakakwira TG PCB?

Kana tembiricha yepamusoro TG PCB ichikwira kune imwe, iyo substrate inoshanduka kubva ku "girazi mamiriro" kuenda ku "rubber state", ipapo tembiricha panguva ino inonzi vitrification tembiricha (TG) yebhodhi. Mune mamwe mazwi, TG ndiyo tembiricha yepamusoro apo iyo substrate inoramba yakasimba.

PCB board ine rudzii chaizvo?

Chiyero kubva pasi kusvika kumusoro chinoratidza sepazasi:

94HB - 94VO - 22F - CEM-1 - CEM-3 - FR-4

Details ndeiyi:

94HB: yakajairika makadhibhodi, kwete fireproof (yakaderera giredhi zvinhu, kufa punching, haigone kuitwa bhodhi remagetsi)

94V0: kadhibhodhi rinodzosa moto (kufa kubaya)

22F: single-sided glass fiberboard (fa punching)

CEM-1: single-sided fiberglass board (kuchera komputa kunofanirwa kuitwa, kwete kufa kubaya)

CEM-3: kaviri-sided fiberglass board (yakaderera zvinhu zvepaviri-mativi bhodhi kunze kwekaviri-mativi bhodhi, chinhu ichi chinogona kushandiswa kune mbiri mapaneru, iyo yakachipa kupfuura FR4)

FR4: kaviri-sided fiberglass board
