PCB igomba kuba irwanya umuriro kandi ntishobora gutwikwa ku bushyuhe runaka, gusa kugirango byoroshye. Ubushyuhe buri gihe bwitwa ubushyuhe bwinzibacyuho (TG Ingingo), bifitanye isano nubunini bwa PCB.

Ni ubuhe butumwa burebure bwa TG hamwe nibyiza byo gukoresha TG BG PCB?

Iyo ubushyuhe bwa tg ya Tg bugeratse, substrate izahinduka kuva "guhagarika ibirahure" kuri "reberi", noneho ubushyuhe muri iki gihe byitwa ubushyuhe bwa vitrific (tg) bwinama. Muyandi magambo, TG nubushyuhe bwo hejuru aho hashobora gukomera.

Ni ubuhe bwoko bwa PCB bufite umwihariko?

Urwego kuva hasi kugeza hejuru rwerekana nkuko bikurikira:

94hb - 94vo - 22f - CEM-1 - CEM-3 - FR-4

Ibisobanuro birakurikira:

94hb: Ikarito isanzwe, ntabwo ari Fireof (ibikoresho byo hasi (bipfa gukubitwa, ntibishobora gukorwa mubuyobozi bwamashanyarazi)

94V0: Ikarita ya Flame Redarbaho (Gupfa Gukubita)

22f: Ikirahuri kimwe cyikirahure fiber (gupfa punching)

CEM-1: Ikibaho kimwe cya fiberglass (Gucukura mudasobwa bigomba gukorwa, ntabwo apfa gukubita)

Cem-3: Ikibaho-Cyinshi Fibberglass (ibikoresho byo hasi cyane byikigo cyinshi

Fr4: Ikibaho-cyinshi cya Fiberglass
