Abaguzi ba elegitoroniki benshi bagura uruganda rwikiguzi cya PCB. Ndetse nabantu bamwe bafite uburambe bwimyaka myinshi mumasoko ya PCB ntibashobora kumva neza impamvu yambere. Mubyukuri, igiciro cya PCB gigizwe nibintu bikurikira:
Ubwa mbere, ibiciro bitandukanye nibikoresho bitandukanye bikoreshwa muri PCB.
Gufata ibice bibiri PCB nkurugero, laminate iratandukanye muri fr-4, cem-3, nibindi hamwe nubunini buva kuri 0.2mm kugeza 3.6mm. Ubunini bw'umuringa buratandukanye na 0.5oz kugeza 6OZ, byose byatumye habaho itandukaniro rinini. Ibiciro bya Illmarmask Ibiciro bitandukanye na Tranmoset Ibikoresho bya Ink nibikoresho bya Great Inkin.
Icya kabiri, ibiciro bitandukanye biterwa nibikorwa bitandukanye.
Ibintu bitandukanye byumusaruro bivamo ibiciro bitandukanye. Nka kibaho cyashyizwe ahagaragara na tin-tin-tin, imiterere ya routing no gukubita, gukoresha imirongo ya ecran ya silk hamwe n'imirongo ya firime yumye izakora ibiciro bitandukanye, bikaviramo bitandukanye.
Icya gatatu, ibiciro bitandukanye biterwa nubunini nubucucike.
PCB izaba ikiguzi gitandukanye nubwo ibikoresho kandi inzira ari bimwe, ariko hamwe nubusa nubucucike. Kurugero, niba hari umwobo 1000 kumababa yumuzunguruko byombi, umwobo wikibaho kimwe ni kinini kuruta 0.6mm na umwobo diameter yundi kibaho ntabwo ari amafaranga atandukanye. Niba ibibaho bibiri byumuzunguruko bimwe mubindi bisabwa, ariko ubugari bwumurongo buratandukanye kandi ibisubizo mubiciro bitandukanye, nkigiciro kimwe cyinama kirenze 0.2mm, mugihe ikindi gifite kiri munsi ya 0.2mm. Kuberako imbaho zitari munsi ya 0.2mm zifite igipimo gifite inenge, bivuze ko igiciro cyumusaruro kiri hejuru.
Icya kane, ibiciro biratandukanye kubera ibisabwa bitandukanye byabakiriya.
Ibisabwa byabakiriya bizagira ingaruka ku buryo butagira inenge mu musaruro. Nkicyuhira hamwe na IPC-A-600e Icyiciro1 gisaba amanota 98%, mugihe gihuye nicyiciro cya 90%, bigatera ibiciro bitandukanye kuruganda hanyuma amaherezo biganisha ku giciro cyibicuruzwa.
