Ibibazo Bikunze Kubazwa
Ese ucunga za PCB zo mu bwoko bwa Prototype cyangwa amabwiriza yo gukora PCB y'ingano nto?
Yego, dushobora gukora PCB mu bunini ubwo aribwo bwose. MOQ = 1pcs (Igice kimwe, cyangwa PCB Panel imwe).
Ese dosiye zanjye zo gushushanya PCB zifite umutekano iyo zigushyikirije kugira ngo zikorerwe?
RichPCBA yubaha uburenganzira bw'umukiriya kandi ntabwo izigera ikora PCB z'undi muntu hamwe n'amadosiye yawe keretse tuyakiriye mu nyandiko.
Uruhushya rwawe, kandi ntabwo tuzasangiza izi dosiye izindi mpande za gatatu. Ubisabye, dushobora gusinya NDA kugira ngo turusheho kugira umutekano.
Ni gute ikiguzi cyo guteranya PCB cyagenwe?
Ibintu bikurikira bigomba gusuzumwa kugira ngo hamenyekane ikiguzi cyo guteranya PCB mu buryo bw'igerageza.
1) Umubare wose w'ibice bigize
2) Ingano n'ingano y'itsinda
3) Ikoranabuhanga ryo guteranya ryakoreshejwe
4) Uburyo busabwa bwo gukora
5) Umubare w'ibice bya PCB n'ibikoresho byakoreshejwe
6) Ibisabwa mu gusiga irangi rijyanye n'imiterere y'umubiri
Ese utanga amabwiriza yo gukora PCB mu byiciro bito?
Yego, turabikora. RichFullJoy yibanda ku gukora PCB ntoya kugeza ku gipimo giciriritse na PCBA.
Kuki nahitamo amadirishya yo gusohora inyandiko ku giciro gito kandi ahendutse?
Kugira ngo hagabanywe amahirwe yo kuba ibicuruzwa bifite inenge mu musaruro mwinshi.
Gufata icyemezo cyo gukorana n'uruganda rwa PCB mu gihe kizaza kugira ngo rukore ibikoresho byinshi.
Kuki ngomba gushyiramo amabaraza ku mbaho zanjye?
Gushyiramo amapanelo birakenewe iyo ingano ya PCB yawe iri munsi ya 50mmx100mm, cyangwa iyo PCB yawe ifite imiterere iyo ari yo yose (ifite uruziga, cyangwa imiterere idasanzwe) itari urukiramende, amapanelo yawe agomba gushyirwamo amapanelo mu buryo butandukanye kugira ngo ateranywe. Nkuko natwe tugukorera PCB yawe, nitumara gutangira gukora amapanelo yawe tuzaba dufite dosiye yo gushyiramo amapanelo (amakuru ya solder paste), tuzajya twohereza amakuru mu ishami rya PCBA kugira ngo dukore stencil ijyanye na PCB iri mu mapanelo.
Mu by'ukuri PCB ni iki?
PCB ni ikibaho gikoreshwa mu gufata chip cyangwa ibindi bice by'ikoranabuhanga. Kugira ngo habeho ibikenewe mu gushushanya, PCB ishobora kuba urwego rumwe cyangwa igizwe n'ibice byinshi. PCB zishobora kandi kuba urwego rumwe cyangwa ebyiri mu gushushanya.
PCB nyinshi zishobora guhuzwa mu gikoresho kimwe, hakoreshejwe uburyo bworoshye cyangwa bukomeye bwo guhuza.
Ese PCB zishobora koroha cyangwa zikomeye?
Igisubizo ni byombi. PCB zishobora kuba zoroshye cyangwa zikomeye mu miterere yazo.
PCB zikomeye zakozwe kugira ngo zidahinduka, kandi akenshi zihendutse kuzikora ugereranyije na PCB zoroshye.
PCB zoroshye, cyangwa board zoroshye, zagenewe kugenda, kuzunguruka no gukurura mu buryo bwifuzwa, kandi zishobora gukuraho gukenera guhuza n'ibindi bice, bishobora kugabanya ikiguzi rusange cy'umusaruro.
RichFullJoy irashobora gukorana nawe kugira ngo imenye igisubizo cyiza ku gishushanyo cyawe — gitanga umusaruro mwinshi.
PCB zikorwa zite?
Ubusanzwe PCB zikorwa mu byiciro byinshi, harimo substrate y'ibikoresho bya RF4 (nk'ibirahuri bya fiberglass) byo gukingira, n'umuringa ukoresha amashanyarazi.
Gukora PCB ni inzira igizwe n'intambwe nyinshi irimo:
#1 Gushushanya PCB – porogaramu igezweho ikoreshwa mu kugena ingano, ingano n'umubare w'ibice bikenewe kuri PCB.
#2 Gucapa igishushanyo mbonera cya PCB – imashini yihariye yitwa plotter printer ikoreshwa mu gucapa igishushanyo mbonera, igizwe n'ibice byinshi by'ahantu hayobora n'ahatayobora. Icapiro riba urufatiro rw'ubutaka, bufata ibice by'inyubako birimo umuringa ku mpande zombi z'urwego.
#3 Gucapa umuringa wo gushyira imbere mu bice by'imbere - igishushanyo mbonera cya PCB gicapishwa kuri laminate irimo firime yagenewe gukorana n'urumuri rwa ultraviolet kugira ngo ihuze neza n'imiterere y'ibice by'amashanyarazi.
#4 Gukuraho umuringa w'inyongera - kubera ko igishushanyo cyatetswe kandi kigatunganywa n'amatara ya ultraviolet, ahantu hamwe na hamwe harakomera kandi umuringa ugafatanywa n'ikibaho. Intambwe ikurikiraho ni ugukoresha umuti wa shimi kugira ngo ukure umuringa utari ngombwa ku kibaho.
#5 Igenzura n'uburyo urwego rushyirwa ku murongo - Iyo umuringa w'inyongera ukuweho, igishushanyo kigomba gusuzumwa neza kugira ngo urwego rwose n'imyobo yo gucukura bifatanye neza. Imashini icukura agapira mu mpande kugira ngo zikomeze ku murongo. Hanyuma indi mashini isuzuma ikibaho kugira ngo irebe niba hari amakosa.
#6 Gusiga irangi ku bice bya PCB – iyo ikibaho kimaze gusuzumwa, hashyirwaho urwego rwa epoxy resin kugira ngo ikibaho gishiremo irangi. Hashyirwaho urundi rwego rwa substrate, hanyuma hashyirwaho ibice bya substrate resin na foil y'umuringa hanyuma bigashyirwa hamwe.
#7 Gucukura imyobo – imashini ikoresha mudasobwa ikoreshwa mu gucukura imyobo inyura mu gice cy’ubutaka n’imbere mu gice cy’imbere ahantu hakwiye ho gushushanya. Iyo icukura rirangiye, umuringa wose usigaye urakurwaho.
#8 Gupfuka PCB – hongerwaho urwego rw'umuringa rwiyongereyeho ku kibaho, hagakurikiraho agakoresho gato k'icyuma kugira ngo karinde urwego rw'inyuma rw'umuringa gucibwa. Kuva aho, PCB yakira agapfukamunwa gapfuka, agatambaro k'ubudodo gafite amakuru y'ingenzi kandi gashyirwamo irangi rishobora gupfukanwa.
Ni iki kiri mu giciro cyose cy'ikiguzi cya PCB?
Ibintu byinshi bifasha mu gushushanya bizafasha mu kumenya ikiguzi cyose cya PCB. Urugero, ingano, umubare w'ibice, ubwoko bwa laminate y'imbaho ikoreshwa, n'umubare wose w'imbaho zikorwa bishobora kugira ingaruka zikomeye ku giciro rusange.
Ni izihe nyungu zo gukoresha ikibaho cyanditse?
PCB zitanga inyungu nyinshi ku bashushanya n'abakora ibikoresho by'ikoranabuhanga. Ibibaho byanditseho:
Zigama umwanya – Zigama umwanya muri igikoresho binyuze mu kwemerera imiyoboro yose kuba ku kibaho ubwacyo, hatabayeho ko umuriro unyura mu nsinga nyinshi.
Emera ko byoroshye gushyiraho no gusana - gupima ibibazo no gusuzuma indwara biroroshye kubikemura kuri PCB, kuko ibice byose biba byanditseho ibimenyetso bisobanutse neza.
Gutanga uburyo bwo guteranya bwihuse – ugereranije n'uburyo busanzwe bwo guhuza imiyoboro, PCB zigabanya igihe cyo guteranya.
Komeza uhagarare – kubera ko ibice byose by’ikoranabuhanga bifatanye n’urubaho rumwe, ntibihinduka iyo byimuwe.
Ikora neza ku bwinshi - PCB zishobora gukorwa ku bwinshi ku giciro gito kurusha ubundi buryo bw'ingufu bwo guhuza ibice.
Tanga ingufu zizewe - kubera ko imiyoboro ikorwa n'imirongo y'umuringa iri ku kibaho, ntabwo ishobora gucika intege.
RichFullJoy ishobora gukora urwego rungana iki rwa PCB mu kibaho kimwe?
Itsinda ryacu ry’inararibonye rishobora gukora imbaho zikomeye zifite urwego rwa 2-68, Vugana n’abahanga bacu kugira ngo bagufashe kumenya PCB ikwiriye ibyo ukeneye.
PCB ikozwe na iki?
Ikibaho ubwacyo kigizwe n'ibice bine by'ingenzi:
Substrate – urufatiro rwa PCB, substrate isanzwe ikorwa muri fiberglass cyangwa ikindi kintu kidatwara amazi. Substrate zishobora kuba urwego rumwe cyangwa nyinshi.
Umuringa - ukoreshwa mu kohereza amashanyarazi, umuringa uri muri PCB ufata umwanya w'insinga.
Maski yo gusoda - icyuma gikoreshwa mu guhuza ubuso bwa PCB n'ibice by'ikoranabuhanga. Maski yo gusoda irinda ibimenyetso by'ikoranabuhanga biri munsi yabyo kugira ngo bitagerwaho n'imimerere mibi.
Silkscreen – urwego rw'udupira tw'iwino dukoreshwa mu gushyira ibimenyetso ku bice by'ikoranabuhanga, imiburo n'ibindi bintu byihariye ku buryo icyo gikoresho gikorana.
Mbere yo gutangira gukora PCB ya nyuma, hagomba kwemezwa igishushanyo mbonera kugira ngo hamenyekane neza ko ibice byose bihujwe kandi bikora neza kugira ngo igikoresho gitange ingufu.
Imbuga za circuit zifite ibara ringana iki?
Bishobora gusa nkaho ari substrate iha PCB ibara, ariko mu by'ukuri ni mask yo gusoda. Substrate akenshi iba ari icyatsi kibisi, ariko mask yo gusoda inyura hejuru yayo ishobora kuba ubururu, umuhondo, umuhondo, umuhengeri, umutuku, umukara, umweru, cyangwa birumvikana, icyatsi kibisi.
Ni ayahe mabara ya soldermask ufite?
Dushobora gushyigikira ubwoko bwose bw'amabara ya solder mask. Ariko, amabara dukunda gukoresha cyane ni Umutuku, Icyatsi, Umukara, Ubururu, n'Uwera.
Ni ibihe bisoza ubuso biboneka?
Indabyo za zahabu zikozwe mu buryo bwa Eictronic, ENlG, Zahabu ikomeye
gutwikira, Urutoki rwa Zahabu, Imerisiyoni y'ifeza, Imerisiyoni y'Iti, HASl
