PCBA board testinhanho yakakosha yekuona kuti yakakwirira-yemhando yepamusoro, yakakwirira-kugadzikana, uye yakakwirira-yakavimbika PCBA zvigadzirwa zvinounzwa kune vatengi, kuderedza kuremara mumaoko evatengi, uye kudzivirira mushure mekutengesa. Idzi dzinotevera nzira dzinoverengeka dzePCBA board test:
- Kuongorora kwekuona ，Kuongorora kwekuona ndekuitarisa iwe pachako. Kuongororwa kwekuona kwePCBA musangano ndiyo nzira yechinyakare muPCBA yekuongorora mhando. Ingoshandisa maziso uye girazi rinokudza kuti utarise dunhu rePCBA bhodhi uye kusungirirwa kwezvinhu zvemagetsi kuti uone kana paine guva. , Kunyange mabhiriji, mamwe tin, kana solder majoini bhiriji, kana pane shoma soldering uye isina kukwana soldering. Uye shandira pamwe negirazi rekukudza kuona PCBA
- In-Circuit Tester (ICT) ICT inogona kuona solder uye chikamu matambudziko muPCBA. Iine kumhanya kukuru, kugadzikana kwepamusoro, tarisa pfupi pfupi, kuvhurika redunhu, kuramba, capacitance.
- Otomatiki optical inspection (AOI) otomatiki kuona hukama husina Indaneti uye pamhepo, uye zvakare ine musiyano uripo pakati pe2D ne3D. Parizvino, AOI inonyanya kufarirwa mufekitori yechigamba. AOI inoshandisa fotographic recognition system kuongorora PCBA board yese nekuishandisa zvakare. Muchina wekuongorora data unoshandiswa kuona kunaka kwePCBA board welding. Iyo kamera inoongorora otomatiki hurema hwePCBA board iri pasi pekuyedzwa. Usati waedza, zvakakosha kuti utarise bhodhi re OK, uye kuchengetedza data rebhodhi reOK muAOI. Kutevera kugadzirwa kwemazhinji kunobva pane iyi OK board. Ita muenzaniso wekutanga kuona kana mamwe mabhodhi ari OK.
- X-ray muchina (X-RAY) Zvemagetsi zvakaita seBGA/QFP, ICT neAOI hazvikwanise kuona kunaka kwekusongera kwepini dzadzo dzemukati. X-RAY yakafanana nebhokisi X-ray machine, inogona kupfuura neCheck the PCB surface kuti uone kana kutengesa kwepini dzomukati kunotengeswa, kana kuiswa kwacho kuri panzvimbo, nezvimwewo. X-RAY inoshandisa X-rays kuti ipinde. iyo PCB board yekuona mukati. X-RAY inoshandiswa zvakanyanya muzvigadzirwa zvine kuvimbika kwakanyanya zvinodiwa, zvakafanana neaviation Electronics, mota dzemagetsi.
- Kuongororwa kwemuenzaniso Pamberi pekugadzirwa kwemazhinji uye kuungana, yekutanga sampuli yekuongorora inowanzoitwa, kuitira kuti dambudziko rekuremara kwakanyanya rigone kudziviswa mukugadzirwa kwemazhinji, izvo zvinotungamira kumatambudziko mukugadzirwa kwePCBA mabhodhi, ayo anonzi yekutanga kuongorora.
- Iyo inobhururuka probe yeinobhururuka probe tester yakakodzera kuongororwa kwepamusoro-kuomarara PCB inoda mari yekuongorora inodhura. Dhizaini uye kuongororwa kweiyo probe inobhururuka inogona kupedzwa muzuva rimwe, uye mutengo wegungano wakaderera. Inokwanisa kutarisa kuvhura, zvikabudura uye kutaridzika kwezvikamu zvakaiswa paPCB. Zvakare, inoshanda nemazvo pakuona chimiro chechikamu uye kurongeka.
- Kugadzira Defect Analyzer (MDA) Chinangwa cheMDA ndechekungoyedza bhodhi kuratidza kukanganisa kwekugadzira. Sezvo hurema hwakawanda hwekugadzira huri nyore nyaya dzekubatanidza, MDA inogumira pakuyera kuenderera. Kazhinji, muongorori anozokwanisa kuona kuvepo kwevanopikisa, capacitors, uye transistors. Kuonekwa kwemasekete akabatanidzwa anogonawo kuwanikwa uchishandisa edziviriro diode kuratidza kwakakodzera chikamu chekuiswa.
- Kuchembera bvunzo. Mushure mekunge PCBA yaita kukwira uye DIP post-soldering, sub-board trimming, kuongorora kwepamusoro uye yekutanga-chidimbu kuyedzwa, mushure mekunge kugadzirwa kwemazhinji kwapera, bhodhi rePCBA richaiswa mukuyedzwa kwekuchembera kuti rione kana basa rega rega rakajairika, zvigadzirwa zvemagetsi zvakajairika, nezvimwe.
