Ukurikije ibikoresho byo gushimangira ubuyobozi bwa PCB, muri rusange bigabanyijemo ubwoko bukurikira:

1. Fenolike PCB impapuro substrate

Kuberako ubu bwoko bwa PCB bugizwe nimpapuro, impapuro zimbaho, nibindi, rimwe na rimwe biba ikarito, ikibaho cya V0, ikibaho cya flame-retardant na 94HB, nibindi. ikomatanyirijwe hamwe na fenolike resin.ikibaho.

Ubu bwoko bwimpapuro substrate ntabwo yaka umuriro, irashobora gukubitwa, ifite igiciro gito, igiciro gito, nubucucike buke.Dukunze kubona insimburangingo ya fenolike nka XPC, FR-1, FR-2, FE-3, nibindi. Kandi 94V0 ni iy'ibipapuro byaka umuriro, bitarinda umuriro.

2. Gukomatanya PCB substrate

Ubu bwoko bwa poro bwitwa kandi ifu yimbuto, hamwe nimpapuro za fibre fibre cyangwa impapuro za fibre fibre nkibikoresho byongerera imbaraga, nigitambara cyibirahure nkibikoresho byubaka hejuru.Ibikoresho byombi bikozwe muri flame-retardant epoxy resin.Hariho uruhande rumwe rw'ibirahuri fibre 22F, CEM-1 hamwe na fibre fibre fibre fibre CEM-3, muri zo CEM-1 na CEM-3 nizo zikunze kwibumbira mu muringa zuzuye umuringa.

3. Ikirahure fibre PCB substrate

Rimwe na rimwe, iba kandi ikibaho cya epoxy, ikibaho cyibirahure, FR4, fibre fibre, nibindi.Ubu bwoko bwumuzunguruko bufite ubushyuhe bwo hejuru kandi ntibwangizwa nibidukikije.Ubu bwoko bwibibaho bukoreshwa kenshi muri PCB zibiri, ariko igiciro gihenze kuruta substrate ya PCB, kandi ubunini busanzwe ni 1.6MM.Ubu bwoko bwa substrate bubereye kubibaho bitandukanye bitanga amashanyarazi, imbaho ​​zo murwego rwohejuru, kandi bikoreshwa cyane muri mudasobwa, ibikoresho bya peripheri, nibikoresho byitumanaho.
