Mw'isi ya elegitoroniki igenda yihuta cyane, gukenera ibikoresho byoroheje, byoroheje kandi bikora cyane byatumye abantu benshi bemera PCBs zoroshye (PCBs zacapwe). Izi mbaho zumuzunguruko zihuza ibintu byiza biranga PCBs kandi byoroshye kugirango bitange ubwizerwe nibikorwa. Ariko, gushushanya PCBs igoye bisaba gutekereza cyane kubintu bitandukanye kugirango ubuziranenge bwibimenyetso, imicungire yubushyuhe, nimbaraga za mashini. Iyi ngingo irasesengura ibitekerezo byingenzi mugushushanya ibice bya PCB bigoye, byibanda kubyimbye, umubare wibice, amategeko yo gushushanya, no guterana no kugerageza.
Umubyimba wumurongo numubare wibice
Kimwe mu bintu byingenzi byerekana igishushanyo mbonera cya laminate ni ukugena uburebure bukwiye n'umubare w'ibyiciro. Ubunini bwa buri cyiciro bugira ingaruka ku buryo butaziguye imikorere no kwizerwa bya PCB. Ibice byimbitse bitanga imbaraga zumukanishi hamwe nubuyobozi bwubushyuhe, mugihe ibice byoroheje byongera ubworoherane no kugabanya ibiro.
Mugihe utegura PCBs ikomeye, igomba kuringanizwa hagati yibi bintu. Gutondekanya ibyiciro byinshi birashobora guteza imbere ubudahangarwa bwibimenyetso mugutanga uburyo bwiza bwo gukingira no kugabanya amashanyarazi (EMI). Ariko, kongera umubare wibice bigora inzira yo gukora kandi bishobora kuvamo ibiciro byinshi. Kubwibyo, abashushanya bagomba gusuzuma neza ibisabwa byihariye bya porogaramu kugirango bamenye iboneza ryiza.
Ibimenyetso byerekana ubunyangamugayo
Ubunyangamugayo bwibimenyetso nibyingenzi muburyo bukomeye PCB igishushanyo, cyane cyane mubikorwa byihuse. Imiterere ya PCB igomba kugabanya gutakaza ibimenyetso no kugoreka, bishobora kugerwaho binyuze muburyo bwitondewe no gutondekanya ibice. Abashushanya bagomba gusuzuma ibintu bikurikira kugirango bongere ubuziranenge bwibimenyetso:
Kugenzura Impedance:Kugumana inzitizi zihoraho muri PCB yose ni ngombwa kugirango ugabanye ibitekerezo no kwemeza ibimenyetso byuzuye. Ibi birashobora kugerwaho mugucunga ubugari bwibisobanuro hamwe nintera iri hagati yinzira.
Indege zubutaka nimbaraga:Gukoresha indege zabugenewe nindege bifasha kugabanya urusaku no kunoza ubuziranenge bwibimenyetso. Izi ndege zitanga inzira-y-impedance yo kugaruka kugezweho, ningirakamaro kubimenyetso byihuse.
Binyuze kuri Layout:Imiterere nubwoko bwa vias bikoreshwa mugushushanya birashobora kugira ingaruka zikomeye kubutabera. Impumyi zishyinguwe kandi zishyinguwe zifasha kugabanya ibimenyetso byerekana inzira ndende no kugabanya inductance, mugihe gushyira neza birashobora gukumira inzira nyabagendwa hagati yinzira zegeranye.
Shushanya amategeko ugomba gukurikiza
Gukurikiza amategeko yashizweho yashizweho ningirakamaro kugirango tumenye neza PCBs. Amategeko amwe yingenzi yo gushushanya agomba gusuzuma harimo:
Ubushobozi buke:Ingano ntoya ya aperture kuri vias na padi igomba gusobanurwa hashingiwe kubushobozi bwo gukora. Ibi byemeza ko PCB zishobora kubyazwa umusaruro kandi nta nenge.
Ubugari n'umurongo:Ubugari hamwe nintera yinzira bigomba kubarwa neza kugirango wirinde ibibazo nkumuzunguruko mugufi hamwe na signal attenuation. Abashushanya bagomba kwifashisha ibipimo bya IPC kugirango bayobore kumurongo ntarengwa w'ubugari n'umwanya.
Gucunga Ubushyuhe:Gucunga neza ubushyuhe nibyingenzi kugirango ukomeze imikorere no kwizerwa bya PCBs ikomeye. Abashushanya bagomba gutekereza kumashanyarazi nubushyuhe kugirango bagabanye ubushyuhe butangwa nimbaraga nyinshi.
Inteko hamwe no kwipimisha
Igikorwa cyo guterana kwa PCBs igoye itanga ibibazo byihariye bigomba gukemurwa mugihe cyicyiciro. Kugirango gahunda yo guterana igende neza, abashushanya bagomba:
Umwanya uhuza ibigega:Umwanya uhagije ugomba kubikwa kubahuza nibindi bice kugirango byoroherezwe guterana no kubungabunga. Ibi nibyingenzi byingenzi mubishushanyo mbonera aho umwanya ari muto.
Imiterere y'Ikizamini:Harimo amanota yikizamini mugushushanya bituma kugerageza no gukemura ibibazo byoroshye mugihe cyo guterana. Abashushanya bagomba gushyiraho ingamba zo kugerageza kugirango barebe ko bitagerwaho bitagize ingaruka kumiterere rusange.
Guhindura no kugoreka radiyo:Igishushanyo kigomba gutekereza kuri PCB ihinduka, cyane cyane mubice bizabera. Abashushanya bagomba kubahiriza radiyo isabwa kugirango birinde kwangirika kwa PCB mugihe cyo kuyikoresha.
Ibishoboka byimikorere ya PCB ikomeye
Hanyuma, uburyo bushoboka bwo gukora PCB bugomba gutekerezwa mugihe cyo gushushanya. Igishushanyo mbonera kigira ingaruka kubushobozi bwo gukora nibiciro. Abashushanya bagomba gukorana cyane nuwakoze PCB kugirango barebe ko igishushanyo gishobora gukorwa neza kandi mu ngengo yimari.
Muri make, gushushanya PCBs igoye bisaba gusobanukirwa byimazeyo ibintu bigira ingaruka kumyizerere no mumikorere. Mugusuzumana ubwitonzi ubunini bwikigero, uburinganire bwibimenyetso, amategeko agenga igishushanyo, hamwe ninteko isabwa hamwe nibisabwa, abashushanya barashobora gukora PCBs zikomeye zujuje ibyifuzo bya elegitoroniki bigezweho. Mugihe ikoranabuhanga rikomeje gutera imbere, PCBs izakomera cyane mubikorwa bya elegitoroniki, bityo abayishushanya bagomba guhora bamenyeshejwe imikorere myiza nibigenda bigaragara muburyo bwa PCB.
