Nigute abakora inteko ya PCB bemeza ubuziranenge bwa PCB?

Mugihe ikoranabuhanga rikomeje gutera imbere, icyapa cyumuzingo cyacapwe (PCBs) cyahindutse ibintu byingenzi mubikoresho byinshi bya elegitoroniki. Kuva kuri terefone zigendanwa kugeza kubikoresho byubuvuzi, PCBs igira uruhare runini mugukora neza imikorere yibi bikoresho. Kubwibyo, abakora inteko ya PCB bagomba gukurikiza uburyo bukomeye bwo kugerageza no kugenzura kugirango ibicuruzwa byabo bibe byiza.Muri iyi nyandiko ya blog, tuzareba intambwe zitandukanye ningamba aba nganda bafata kugirango PCBs zujuje ubuziranenge.

Igenzura ryambere ryerekanwa:

Intambwe yambere mubikorwa byo kugenzura ubuziranenge ni ubugenzuzi bugaragara bwa PCB. Abakora inteko ya PCB basuzumana ubwitonzi imbaho ​​zumuzunguruko ku nenge iyo ari yo yose igaragara nko gushushanya, amenyo, cyangwa ibice byangiritse. Iri genzura ryambere rifasha kumenya ibibazo byose bigaragara bishobora kugira ingaruka kumikorere ya PCB cyangwa kwizerwa.

ikizamini cyimikorere:

Nyuma yubugenzuzi bwambere burangiye, uwabikoze akomeza kwipimisha kumikorere. Iyi ntambwe ikubiyemo gusuzuma imikorere y'amashanyarazi ya PCB ukora ibizamini bitandukanye kuri PCB. Ibi bizamini bigenzura ko PCB ikora nkuko byari byitezwe kandi yujuje ibyangombwa bisabwa. Igeragezwa ryimikorere rishobora kubamo ibizamini nka power-up igeragezwa, kugera kubizamini, gusesengura ibimenyetso byerekana ibimenyetso, hamwe no gupima imbibi.

Igenzura ryikora ryikora (AOI):

Kugirango hamenyekane ubuziranenge nukuri kwinteko za PCB, abayikora bakunze gukoresha sisitemu yo kugenzura optique (AOI). AOI ikoresha kamera-nini cyane kugirango ifate amashusho ya PCB ziteranijwe. Porogaramu ikoreshwa na AI noneho igereranya aya mashusho nigishushanyo mbonera, ikagaragaza itandukaniro iryo ariryo ryose nko kubura ibice, kudahuza cyangwa kugurisha inenge. AOI itezimbere cyane ubunyangamugayo n'umuvuduko wo kugenzura, kandi irashobora kumenya nudusimba duto duto ubugenzuzi bwintoki bushobora kubura.

Igenzura rya X-ray:

Kuri PCB igoye ifite ibice byihishe cyangwa bitagaragara, kugenzura x-ray birashobora kuba ingirakamaro. Igenzura rya X-ryemerera abayikora kureba binyuze murwego rwa PCB no kumenya inenge iyo ari yo yose ishobora kuba, nk'ikiraro cyagurishijwe cyangwa ubusa. Ubu buryo bwo kwipimisha budasenya bufasha kumenya ibibazo bidashobora gutahurwa nubugenzuzi bugaragara cyangwa AOI, byemeza uburinganire bwimiterere n'imikorere ya PCB.

Ikizamini cyo kumurongo (ICT):

Igeragezwa ryumuzunguruko (ICT) niyindi ntambwe ikomeye mugikorwa cyo kugenzura ubuziranenge. Mugihe cyibikorwa bya ICT, abayikora bakoresha ibikoresho kabuhariwe kugirango basuzume imikorere yibice hamwe nizunguruka kuri PCB. Mugukoresha voltage nibimenyetso byihariye, ikizamini gishobora kumenya ibice byose byananiranye, umuzunguruko mugufi cyangwa uruziga rufunguye. ICT ifasha kumenya ibice cyangwa amahuza adakwiye bishobora gutera PCB kunanirwa cyangwa gukora neza.

Ikizamini cyo gusaza:

Kugirango usuzume igihe kirekire kwizerwa no gutuza kwa PCBs, abayikora akenshi bakora ibizamini byo gutwika kuri bo. Kwipimisha gutwika bikubiyemo kwerekana PCB ubushyuhe bwinshi (mubisanzwe hejuru yimikorere yayo) mugihe kinini. Igeragezwa rikomeye rifasha kumenya inenge cyangwa intege nke zishobora kuboneka kandi ikemeza ko PCB ishobora kwihanganira imikorere isanzwe nta gutsindwa.

Kwipimisha ibidukikije:

Kubera ko PCB zishobora kwibasirwa n’ibidukikije bitandukanye, ni ngombwa gusuzuma igihe kirekire n'imikorere yabyo mu bihe bitandukanye. Kwipimisha ibidukikije bikubiyemo kwerekana PCB kurenza ubushyuhe, ubushuhe, kunyeganyega no guhungabana. Ibi bizamini byerekana guhangana na PCBs mubihe bibi kandi byemeza ko bishobora kwihanganira ibyifuzo byimikorere-yisi.

ikizamini cya nyuma:

Mbere yuko PCB zoherezwa kubakiriya, bakorerwa igenzura rya nyuma kugirango barebe ko bujuje ibisabwa byose. Iri genzura ririmo kugenzura neza isura ya PCB, ibipimo, imikorere y'amashanyarazi n'imikorere. Igenzura ryanyuma rigabanya amahirwe yo kuba PCB ifite inenge igezwa kubakiriya, bityo ikemeza ubuziranenge bwo hejuru.

Mu gusoza, abakora inteko ya PCB bakora urukurikirane rwo kugerageza no kugenzura kugirango barebe neza ibicuruzwa byabo.Igenzura ryibonekeje, ibizamini bikora, AOI, ubugenzuzi bwa X-ray, ICT, gupima gutwika, gupima ibidukikije no kugenzura bwa nyuma byose bigira uruhare runini mugikorwa cyo kugenzura ubuziranenge. Mugukurikiza byimazeyo ubu buryo, ababikora barashobora kwemeza ko PCB bakora zujuje ubuziranenge busabwa, bityo bagaha abakiriya ibicuruzwa byizewe kandi byujuje ubuziranenge.
