Mwisi yagutse ya elegitoroniki, impfunyapfunyo PCB ikoreshwa mukwerekeza ku kibaho cyacapwe.Ariko, kubatamenyereye ubuhanga bwubu buhanga bukomeye, ijambo rishobora kuba urujijo kandi akenshi ritera kwibaza nka "PCB isobanura iki?"Niba ubona ufite amatsiko kuri PCB kandi ukaba ushaka gusobanukirwa neza shingiro ryabo, uri ahantu heza.Iyi blog igamije kuguha ibisobanuro byoroshye kubyumva kubijyanye na PCB, akamaro kayo nibisabwa mubikorwa byisi byikoranabuhanga.
Sobanura PCB
Ikibaho cyumuzingo cyacapwe (PCBs) nibintu byingenzi mubikoresho bya elegitoroniki bigezweho.Zigizwe nimpapuro ziringaniye zidatwara ibintu nka fiberglass ikora nkibanze ryo gushiraho ibikoresho bya elegitoroniki bitandukanye.Ibi bice bihujwe numuyoboro wumuringa wumuringa, witwa traces, ushyizwe mubibaho.
1. Imiterere n'imikorere
Intego nyamukuru ya PCB nugutanga ubufasha bwimashini hamwe nu mashanyarazi hagati yibikoresho bya elegitoroniki.Irashinzwe kwemeza neza itumanaho n’itumanaho hagati yibice bitandukanye, harimo imiyoboro ihuriweho (IC), résistoriste, transistors, capacator, nibindi byinshi.Uburyo bwo gukurikirana ibintu ku mbaho zumuzunguruko bifasha koroshya umuvuduko w'amashanyarazi kugirango ibikoresho bya elegitoronike bikore neza.
2. Ibyiza bya PCB
Kwinjiza PCB mubikoresho bya elegitoronike bifite ibyiza byinshi.Ubwa mbere, igishushanyo mbonera cyabo gifasha miniaturizasiya, guhuza umwanya mubikoresho bya elegitoroniki.Byongeye kandi, gukoresha PCB bigabanya kandi amahirwe yamakosa mugihe cyo guterana, kuko ibice bishyirwa mubikorwa, byoroshya inzira yo gukora.PCBs nayo itanga igihe kirekire ugereranije nubundi buryo bwo gukoresha insinga.Ibicuruzwa bigurishijwe byemeza guhuza umutekano kandi bigabanya ibyago byinsinga zidafunguye cyangwa guhuza nabi.
3. Ubwoko bwa PCB
PCBs irashobora gutandukana muburyo bugoye, igishushanyo, numubare wibice kugirango uhuze ibikenewe bya porogaramu zihariye.Ubwoko bumwe busanzwe bwa PCB burimo urwego rumwe, kabiri-na PCB nyinshi.PCB igizwe numurongo umwe wumuringa kuruhande rumwe, mugihe PCB ifite ibice bibiri ifite umuringa kumpande zombi.PCBs nyinshi igizwe nibice byinshi byegeranye kandi bigahuzwa binyuze mu mwobo wacukuwe witwa vias, bigatuma umubare munini wibigize uhuza kandi ukanoza imikorere.
4. Uburyo bwo gukora PCB
Igikorwa cyo gukora PCB kirimo intambwe nyinshi.Ku ikubitiro, ibipimo byubuyobozi nuburyo imiterere yibigize byakozwe hifashishijwe porogaramu ifashwa na mudasobwa (CAD).Igishushanyo kimaze kurangira, cyimurirwa ku kibaho cyumuzunguruko binyuze muri firime yerekana amafoto cyangwa mask yo gukingira.Ahantu h'umuringa hagaragara noneho hashyirwa hanze hakoreshejwe igisubizo cyimiti, hasigara ibimenyetso byifuzwa.Hanyuma, ibice byashyizwe ku kibaho bikagurishwa, bikarangiza inzira yo guterana.
mu gusoza
Muncamake, imbaho zicapye zicapye (PCBs) zifite uruhare runini muri electronics, zitanga amashanyarazi akenewe hamwe nubufasha bwibikoresho kubikoresho bitabarika.Gusobanukirwa shingiro rya PCBs, harimo imiterere, imikorere, inyungu, nibikorwa byinganda, nibyingenzi mugusobanukirwa ibikoresho bya elegitoroniki duhura nabyo buri munsi.Mugihe ikoranabuhanga rikomeje gutera imbere, PCBs ntagushidikanya ko izakomeza kuba umusingi woguhanga udushya, igenda ihinduka kugirango ikemure ibibazo bishya nibikenewe.
