I-PCB kumele imelane nomlilo futhi ayikwazi ukusha ngezinga lokushisa elithile, ukuze ithambe kuphela. Iphoyinti lokushisa ngalesi sikhathi libizwa ngokuthi izinga lokushisa lokushintsha kwengilazi (iphoyinti le-TG), elihlobene nokuzinza kosayizi we-PCB.

Yiziphi i-TG PCB ephezulu kanye nezinzuzo zokusebenzisa i-TG PCB ephezulu?

Lapho izinga lokushisa eliphezulu le-TG PCB likhuphuka liye kwezinye, i-substrate izoshintsha isuka “kwisimo sengilazi” iye “kwisimo senjoloba”, khona-ke izinga lokushisa ngalesi sikhathi libizwa ngokuthi izinga lokushisa le-vitrification (TG) lebhodi. Ngamanye amazwi, i-TG izinga lokushisa eliphakeme kakhulu lapho i-substrate ihlala iqinile.

Ibhodi le-PCB linaluphi uhlobo ngokukhethekile?

Izinga elisuka phansi liye phezulu libonakala lingezansi:

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

Imininingwane imi kanje:

I-94HB: amakhadibhodi ajwayelekile, hhayi angashi (impahla yebanga eliphansi kakhulu, i-die punching, ayinakwenziwa ibhodi lamandla)

I-94V0: ikhadibhodi elibuyisela amalangabi (i-die punching)

I-22F: i-fiberboard yengilazi enohlangothi olulodwa (i-die punching)

I-CEM-1: ibhodi le-fiberglass elinohlangothi olulodwa (ukubhola ngekhompyutha kufanele kwenziwe, hhayi ukubhoboza)

I-CEM-3: ibhodi le-fiberglass elinezinhlangothi ezimbili (into ephansi kunazo zonke yebhodi elinamaceleni amabili ngaphandle kwebhodi elinamaceleni amabili, le nto ingasetshenziselwa amaphaneli aphindwe kabili, ashibhile kakhulu kune-FR4)

I-FR4: ibhodi ye-fiberglass enezinhlangothi ezimbili
