Gahunda yo gutunganya PCBA iragoye cyane, harimo inzira yo gukora PCB yubuyobozi, gutanga amasoko no kugenzura, guteranya ibice bya SMT, gucomeka kwa DIP, kugerageza PCBA nibindi bikorwa byingenzi.Muri byo, ikizamini cya PCBA nicyo gihuza cyane kugenzura ubuziranenge mubikorwa byose byo gutunganya PCBA, bigena imikorere yanyuma yibicuruzwa.Ni ubuhe buryo bwo gukora ibizamini bya PCBA? Ikizamini cya PCBA gikubiyemo ahanini: Ikizamini cya ICT, ikizamini cya FCT, ikizamini cyo gusaza, ikizamini cy'umunaniro, ikizamini cy’ibidukikije gikabije ubu buryo butanu.

1, Ikizamini cya ICT gikubiyemo cyane cyane umuzenguruko kuri-off, voltage nagaciro kagezweho hamwe nu murongo uhetamye, amplitude, urusaku, nibindi.

2, Ikizamini cya FCT gikeneye gukora firime ya IC, kwigana imikorere yubuyobozi bwose bwa PCBA, gushakisha ibibazo mubikoresho bya software na software, kandi bifite ibikoresho bikenewe byo gutunganya ibicuruzwa hamwe nibisubizo.

3, ikizamini cyumunaniro nugushushanya cyane cyane kubuyobozi bwa PCBA, no gukora ibikorwa byinshyi kandi birebire byimikorere, kureba niba gutsindwa bibaho, gucira urubanza amahirwe yo gutsindwa mukizamini, no gutanga ibitekerezo kumikorere ya PCBA ikibaho mubikoresho bya elegitoroniki.

4, ikizamini mubidukikije bikabije ni ukugaragaza cyane cyane ikibaho cya PCBA ubushyuhe, ubushuhe, kugabanuka, kugabanuka, kunyeganyega agaciro ntarengwa, kugirango ubone ibisubizo byikizamini cyurugero rudasanzwe, kugirango hamenyekane ubwizerwe bwubuyobozi bwose bwa PCBA icyiciro.

5. inzira yo gutunganya, hashobora kubaho ibibazo bitandukanye kubera ibikoresho cyangwa imikorere idakwiye, ntishobora kwemeza ko ibicuruzwa byakozwe byujuje ibisabwa, bityo rero birakenewe ko hakorwa ibizamini bya PCB kugirango buri gicuruzwa kitazagira ibibazo byubuziranenge.

Nigute wapima pcba

Ikizamini cya PCBA uburyo busanzwe, hariho ibi bikurikira:

1. Ikizamini cy'intoki

Igeragezwa ryintoki nugushingira muburyo bwo kureba kugirango ugerageze, binyuze mubyerekezo no kugereranya kugirango wemeze kwishyiriraho ibice kuri PCB, iri koranabuhanga rirakoreshwa cyane.Nyamara, umubare munini nibice bito bituma ubu buryo butagabanuka.Byongeye kandi, inenge zimwe zikora ntizimenyekana byoroshye kandi gukusanya amakuru biragoye.Muri ubu buryo, hakenewe ubundi buryo bwo gupima umwuga.

2, Igenzura ryikora ryikora (AOI)

Automatic optique detection, izwi kandi kwizerwa ryikora ryikora, ikorwa na detector idasanzwe, ikoreshwa mbere na nyuma yo kugaruka, kandi polarite yibigize nibyiza.Biroroshye gukurikira kwisuzumisha nuburyo busanzwe, ariko ubu buryo ni bubi kugirango bumenye inzira ngufi.

3, imashini igerageza inshinge

Kwipimisha inshinge byamamaye mumyaka mike ishize kubera iterambere muburyo bwa tekinike, umuvuduko, no kwizerwa.Mubyongeyeho, icyifuzo gikenewe kuri sisitemu yikizamini hamwe no guhindura byihuse hamwe nubushobozi buke bwa jig busabwa mubikorwa bya Prototype no gukora amajwi make bituma igerageza rya inshinge ziguruka guhitamo neza.4.Ikizamini cyimikorere

Ubu ni uburyo bwo gupima PCB runaka cyangwa igice runaka, bikorwa nibikoresho kabuhariwe.Hariho ubwoko bubiri bwingenzi bwo kugerageza imikorere: Ikizamini cyanyuma cyibicuruzwa na Mock-up.

5. Gukora Isesengura Ryuzuye (MDA)

Ibyiza byingenzi byubu buryo bwikizamini nigiciro gito cyo hejuru, gisohoka cyane, byoroshye gukurikira isuzumabumenyi hamwe byihuse byihuse byumuzunguruko no kwipimisha kumugaragaro.Ikibi ni uko ibizamini bikora bidashobora gukorwa, mubusanzwe nta kimenyetso cyerekana ikizamini, ibikoresho bigomba gukoreshwa, kandi ikiguzi cyibizamini ni kinini.

ibikoresho bya pcba

Ibikoresho bisanzwe bya PCBA ni: Ikizamini cya ICT kumurongo, ikizamini cya FCT nikizamini cyo gusaza.

1, Ikizamini cya ICT kumurongo

ICT nikizamini cyikora kumurongo, gifite porogaramu zitandukanye kandi byoroshye gukora.ICT ikora kuri enterineti ikora cyane cyane kugenzura ibikorwa, irashobora gupima guhangana, ubushobozi, inductance, umuzenguruko.Nibyiza cyane cyane mugutahura uruziga rufunguye, uruziga rugufi, ibyangiritse, nibindi, ahantu nyaburanga, amakosa yoroshye.

Ikizamini cyimikorere ya FCT

Ikizamini cyimikorere ya FCT nugutanga ibikorwa byokwigana nko kwishima no kwikorera kubuyobozi bwa PCBA, no kubona ibipimo bitandukanye bya leta byubuyobozi kugirango hamenyekane niba ibipimo byimikorere byubuyobozi byujuje ibisabwa.Ibizamini bya FCT bikora cyane cyane birimo voltage, ikigezweho, imbaraga, ibintu byingufu, inshuro, cycle yumurimo, umucyo namabara, kumenyekanisha imiterere, kumenyekanisha amajwi, gupima ubushyuhe, gupima umuvuduko, kugenzura ibyerekezo, gutwika FLASH na EEPROM.

3. Ikizamini cyo gusaza

Ikizamini cyo gusaza bivuga inzira yo kwigana ibintu bitandukanye bigira uruhare muburyo nyabwo bwo gukoresha ibicuruzwa kugirango ukore igeragezwa ryongera imiterere.Ubuyobozi bwa PCBA bwibicuruzwa bya elegitoronike burashobora gukoreshwa igihe kinini cyo kwigana imikoreshereze yabakiriya, kwinjiza / gusohora ibizamini kugirango ibikorwa byayo byuzuze isoko.

Ubu bwoko butatu bwibikoresho byipimisha birasanzwe mubikorwa bya PCBA, kandi ibizamini bya PCBA mubikorwa byo gutunganya PCBA birashobora kwemeza ko inama ya PCBA yagejejwe kubakiriya yujuje ibyifuzo byabakiriya kandi bikagabanya cyane igipimo cyo gusana.
