PCB inofanira kunge iri moto inodzivirira uye haigoni kupisa pane imwe tembiricha, chete kuti yakanyorova. Iyo tembiricha nguva panguva ino inonzi iyo girazi transition tembiricha (tg point), inoenderana nehukuru hwekugadzikana kwePCB.

Ndezvipi zvakakwira tg PCB uye zvakanakira kushandisa yakakwira tg PCB?

Kana tembiricha yeTG PCB ichisimuka kune imwe ndeyekuti "Substrate ichachinja kubva ku" Girazi State "ku" Rubber State ", tembiricha panguva ino inodaidzwa kuti tembiricha yekushisa (TG) yebhodhi. Mune mamwe mazwi, TG ndiyo yepamusoro tembiricha iyo iyo iyo substrate inoramba yakasimba.

Ichipi cheti chePCB chakananga?

Chikamu kubva pasi kusvika kumusoro kuratidza sepazasi:

94HB - 94V - CEM-1 - CEM-3 - Fr-4

Nhoroondo dziri seinotevera:

94HB: Yakajairika kadhibhodi, kwete ma fireproof (yakaderera giredhi zvinhu, kufa punching, haigone kuitwa mune magetsi bhodhi)

94v0: murazvo unodzoreredza kadhibhodi (dife punching)

22f: Imwe-yakagadzirirwa girazi fiberboard (dife punching)

CEM-1: Single-Sided Fiberglass Bhodhi (Dhizaina Kudhirowa inofanira kuitwa, kwete kufa punching)

CEM-3: Doubt Designglass Bhodhi (iyo yakaderera zvinyorwa zvebhukadzi mbiri kunze kwebato rakapetwa kaviri

Fr4: Double-Sided Fiberglass Bhodhi
