Nkumutanga tekinoroji zitandukanye za PCB, Umubumbe, uburyo bwo guhitamo ibikoresho bisanzwe hamwe numurongo munini wubwoko butandukanye bwa PCB bushobora gutwikirwa kandi burigihe buboneka munzu.
Ibisabwa kubindi cyangwa kubikoresho byihariye birashobora kandi guhura mubihe byinshi, ariko, bitewe nibisabwa nyabyo, kugeza ku minsi 10 y'akazi birashobora gukenerwa kugirango ibikoresho bibone.
Kora hamwe natwe kandi muganire kubyo ukeneye hamwe nitsinda ryaka cyangwa amakipe ya kami.
Ibikoresho bisanzwe bifatiwe mububiko:

Stactup
Igice cya 4 cyacapwemo Ikibaho Cyumuzunguruko ni gifite 3 mubice bimwe hamwe nigice cyinkomoko gukora4 ibice byose.
Ibi bice byose bikoreshwa mugukurikirana ibimenyetso.
Ibirenge bibiri byimbere biri kuryama imbere kandi akenshi bihinduka nkimibare yububasha cyangwa bikunze kuvugwa nkibimenyetso.
Kuvuga gusa stactup 4-layer ni 2 ya senta VCC nuruhande rwubutaka.
Ingingo z'ingenzi zo kugura PCB
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.
