Ibikoresho
Nkumuntu utanga tekinoroji ya PCB itandukanye, ingano, kuyobora igihe cyo guhitamo, dufite guhitamo ibikoresho bisanzwe hamwe numuyoboro mugari wubwoko butandukanye bwa PCB ushobora gutwikirwa kandi uhora uboneka munzu.
Ibisabwa kubindi cyangwa kubikoresho byihariye nabyo birashobora kuzuzwa mubihe byinshi, ariko, ukurikije ibisabwa nyabyo, hashobora gukenerwa iminsi igera ku 10 yakazi kugirango ugure ibikoresho.
Twandikire natwe hanyuma muganire kubyo ukeneye hamwe numwe mubigurisha cyangwa itsinda rya CAM.
Ibikoresho bisanzwe bibitswe:

Ububiko
Igice cya 4 cyacapwe cyumuzunguruko stackup gifite 3 murwego rumwe hamwe nubutaka bwubutaka bigatuma ibice 4 byose hamwe.
Izi nzego zose zikoreshwa muguhuza ibimenyetso.
Imbere ya frst ibiri yimbere irambaraye mumbere kandi akenshi ikoreshwa nkibikoresho byamashanyarazi cyangwa bikunze kuvugwa nko kuyobora ibimenyetso.
Vuga gusa ibice 4 bya PCB stackup ifite 2 ya singlea VCC hamwe nubutaka.
Ingingo z'ingenzi zo kugura pcb
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.
