PCB iintambo sisixhobo esiphambili kuyilo lwePCB. Abanye abahlobo abazi ukuba bubungakanani bentambo ye-PCB ebekwe njani ngokubanzi. Apha sazisa ngobungakanani bokubumba iintambo kwePCB ngokubanzi.

Uluhlu lweentambo ze-PCB ngokubanzi zokujonga imiba emibini. Inye bubungakanani beli xesha langoku, ukuba yangoku ngamagama amakhulu, umgca awunakubhitya kakhulu; Okwesibini kukuthathela ingqalelo ubungakanani bokwenza ipleyiti kumzi-mveliso webhodi ukuba ikhoyo ngoku incinci, umgca unokuba mncinci, kodwa ubhitye kakhulu, umzi-mveliso webhodi yePCB awunakuveliswa, okanye uveliswe kodwa isivuno siyenyuka, ke Kuya kufuneka siqwalasele ingxaki yebhodi yomzi-mveliso.

Ububanzi bomgca we-PCB ububanzi ngokubanzi busetelwe

Ububanzi bomgca ngokubanzi bulawulwa kwi-6 / 6mil, kwaye ukhetho lomngxunya yi-12mil (0.3mm), enokuveliswa ngabenzi abaninzi be-PCB ngexabiso eliphantsi.

Umgca wobubanzi bomgca oshiye isithuba kulawulo lwe-4 / 4mil, ngokukhetha umngxunya we-8mil (0.2mm), ngaphezulu kwesiqingatha sabenzi be-PCB banokuvelisa, kodwa ixabiso liya kubiza kancinci kunangaphambili.

Ububanzi obuncinci bomgca bulawulwa kwi-3.5 / 3.5mil, kunye nokukhethwa komngxunya yi-8mil (0.2mm). Bambalwa abavelisi bePCB abanokuvelisa i-PCB, kwaye ixabiso liya kubiza kakhulu.

Ububanzi obuncinci bomgca bulawulwa kwi-2 / 2mil, kwaye ukhetho lomngxunya luyi-4mil (0.1mm). Abavelisi abaninzi bePCB abanakuyivelisa, kwaye olu hlobo lwexabiso lelona liphezulu.

Ububanzi bomgca bunokuseta ngokobuninzi be-PCB yoyilo. Ukuba uxinano lincinci, ububanzi bomgca kunye nokushiyeka komgca kunokucwangciswa ukuba kukhulu. Ukuba uxinano lukhulu, ububanzi bomgca kunye nokushiyeka komgca kunokucwangciswa ukuba kuncinci:

1) 8 / 8mil, 12mil (0.3mm) yentsimbi.

2) 6 / 6mil, 12mil (0.3mm) ngokusebenzisa umngxuma.

3) 4 / 4mil, 8mil (0.2mm) ngokusebenzisa umngxuma.

4) 3.5 / 3.5mil, 8mil (0.2mm) ngokusebenzisa umngxuma.

5) 3.5 / 3.5mil, 4mil ngembobo (0.1mm, ukubhola laser).

6) 2 / 2mil, 4mil ngembobo (0.1mm, ukubhola laser).
