Abaguzi benshi muruganda rwa elegitoroniki barayobewe kubiciro bya PCBs.ndetse nabantu bamwe bafite uburambe bwimyaka myinshi mumasoko ya PCB ntibashobora kumva neza impamvu yambere.Mubyukuri, igiciro cya PCB kigizwe nibintu bikurikira:
Ubwa mbere, ibiciro biratandukanye kubera ibikoresho bitandukanye bikoreshwa muri PCB.
Dufashe ibyiciro bibiri bisanzwe pcb nkurugero, laminate iratandukanye kuva FR-4, CEM-3, nibindi bifite uburebure buri hagati ya 0.2mm na 3.6mm.Ubunini bwumuringa buratandukanye kuva 0.5Oz kugeza 6Oz, byose byateje itandukaniro rinini.Ibiciro bya wino ya soldermask nayo itandukanye nibintu bisanzwe bya termosetting ya wino nibikoresho bya wino bifotora.
Icya kabiri, ibiciro biratandukanye bitewe nuburyo butandukanye bwo gukora.
Uburyo butandukanye bwo gutanga umusaruro bivamo ibiciro bitandukanye.Nkibibaho bikozwe muri zahabu hamwe nu rubaho rwometseho amabati, imiterere ya maritike yo gukubita no gukubita, gukoresha imirongo ya silike yerekana imirongo hamwe nimirongo ya firime yumye bizatanga ibiciro bitandukanye, bivamo ibiciro bitandukanye.
Icya gatatu, ibiciro biratandukanye kubera ubunini n'ubucucike.
PCB izaba igiciro gitandukanye nubwo ibikoresho nibikorwa ari bimwe, ariko hamwe nuburyo butandukanye.Kurugero, niba hari ibyobo 1000 kumabaho yombi yumuzunguruko, umwobo wa diameter yumubaho umwe uruta 0,6mm naho umwobo wa diameter wurundi ruba uri munsi ya 0,6mm, bizatanga ibiciro bitandukanye byo gucukura.Niba imbaho ebyiri zumuzunguruko zisa mubindi byifuzo, ariko ubugari bwumurongo buratandukanye nabwo bivamo ibiciro bitandukanye, nkubugari bumwe bwibibaho binini kurenza 0.2mm, mugihe ikindi gifite munsi ya 0.2mm.Kuberako ubugari bwibibaho munsi ya 0.2mm bifite igipimo kinini gifite inenge, bivuze ko igiciro cyumusaruro kiri hejuru yubusanzwe.
Icya kane, ibiciro biratandukanye kubera ibyifuzo bitandukanye byabakiriya.
Ibisabwa byabakiriya bizagira ingaruka kuburyo butaziguye ku gipimo kitagira inenge mu musaruro.Nka kibaho kimwe cyemera IPC-A-600E icyiciro1 gisaba igipimo cyatsinzwe cya 98%, mugihe amasezerano yo mucyiciro cya 3 gisaba kugira igipimo cyatsinzwe cya 90% gusa, bigatuma ibiciro bitandukanye byuruganda kandi amaherezo biganisha kumahinduka yibiciro byibicuruzwa.
