PCBA board testndi sitepe yofunika kuonetsetsa kuti apamwamba, kukhazikika, ndi mkulu-kudalirika mankhwala PCBA anaperekedwa kwa makasitomala, kuchepetsa zilema m'manja mwa makasitomala, ndi kupewa pambuyo-zogulitsa. Zotsatirazi ndi njira zingapo za PCBA board test:
- Kuyang'ana kowoneka ,Kuyendera kowoneka ndikuyang'ana pamanja. Kuyang'ana kowoneka kwa msonkhano wa PCBA ndiye njira yakale kwambiri pakuwunika khalidwe la PCBA. Ingogwiritsani ntchito maso ndi galasi lokulitsa kuyang'ana dera la bolodi la PCBA ndi kutsekemera kwa zigawo zamagetsi kuti muwone ngati pali mwala wamanda. , Ngakhale milatho, malata ochulukirapo, kaya zolumikizira za solder ndi zomangika, kaya pali solder wocheperako komanso wosakwanira. Ndipo gwirizanani ndi galasi lokulitsa kuti muzindikire PCBA
- In-Circuit Tester (ICT) ICT imatha kuzindikira zovuta zowotchera ndi zigawo mu PCBA. Ili ndi liwiro lalikulu, kukhazikika kwakukulu, fufuzani dera lalifupi, lotseguka, kukana, mphamvu.
- Automatic Optical inspection (AOI) yodziwikiratu ubale ili ndi pa intaneti komanso pa intaneti, komanso ili ndi kusiyana pakati pa 2D ndi 3D. Pakadali pano, AOI ndiyodziwika kwambiri mufakitale yopangira zigamba. AOI imagwiritsa ntchito makina ozindikira zithunzi kusanthula bolodi yonse ya PCBA ndikuigwiritsanso ntchito. makina kusanthula deta ntchito kudziwa khalidwe la PCBA bolodi kuwotcherera. Kamera imangoyang'ana zolakwika za gulu la PCBA poyesedwa. Musanayesedwe, m'pofunika kudziwa bolodi ya OK, ndikusunga deta ya OK board mu AOI. Kupanga kwakukulu kotsatira kumatengera bolodi la OK. Pangani chitsanzo choyambirira kuti muwone ngati matabwa ena ali bwino.
- Makina a X-ray (X-RAY) Pazigawo zamagetsi monga BGA/QFP, ICT ndi AOI sizingazindikire momwe mapini awo amkati amagulitsira. X-RAY ikufanana ndi chifuwa cha X-ray makina, omwe amatha kudutsa Yang'anani pamwamba pa PCB kuti muwone ngati kutsekemera kwa zikhomo zamkati kumagulitsidwa, ngati kuyika kulipo, etc. X-RAY imagwiritsa ntchito X-ray kuti ilowetse. PCB board kuti muwone zamkati. X-RAY imagwiritsidwa ntchito kwambiri pazinthu zodalirika kwambiri, zofanana ndi zamagetsi zamagetsi, zamagetsi zamagalimoto.
- Zitsanzo kuyendera Pamaso kupanga misa ndi msonkhano, woyamba chitsanzo anayendera kawirikawiri ikuchitika, kuti vuto la anaikira zilema akhoza kupewedwa kupanga misa, zomwe zimabweretsa mavuto kupanga matabwa PCBA, amene amatchedwa woyamba anayendera.
- Kufufuza kowuluka kwa choyesa chowulukira ndi choyenera kuyang'ana ma PCB ovuta kwambiri omwe amafunikira ndalama zoyendera zokwera mtengo. Mapangidwe ndi kuyang'anitsitsa kwa kafukufuku wowuluka akhoza kumalizidwa tsiku limodzi, ndipo mtengo wa msonkhano ndi wotsika kwambiri. Imatha kuyang'ana zotsegula, zazifupi ndi mawonekedwe a zigawo zomwe zayikidwa pa PCB. Komanso, zimagwira ntchito bwino pozindikira masanjidwe azinthu ndi kulinganiza.
- Manufacturing Defect Analyzer (MDA) Cholinga cha MDA ndikungoyesa gululo kuti liwonetse zolakwika zopanga. Popeza zolakwika zambiri zopanga ndizosavuta kulumikizana, MDA imangokhala pakuyesa kupitiliza. Kawirikawiri, woyesa adzatha kuzindikira kukhalapo kwa resistors, capacitors, ndi transistors. Kuzindikira kwa mabwalo ophatikizika kumathanso kupezedwa pogwiritsa ntchito ma diode odzitchinjiriza kuwonetsa kuyika koyenera kwa zigawo.
- Mayeso okalamba. Pambuyo PCBA wadutsa kukwera ndi DIP post-soldering, subboard yokonza, kuyang'ana pamwamba ndi kuyesedwa koyamba, pambuyo pa kupanga misala, gulu la PCBA lidzayesedwa ku ukalamba kuyesa ngati ntchito iliyonse ndi yachibadwa, zida zamagetsi ndizabwinobwino, etc.
