Nzira dzeKuyedza PCBA: AOI, ICT, Flying Probe, uye Functional Test

Kuyedzwa kwePCBA inzira iyo mugadziri wechibvumirano anoratidza nayo kuti bhodhi rakaungana rakavakwa nemazvo uye rinoshanda — uye hapana bvunzo imwe chete inobata zvese. Kugadzirwa chaiko kunosanganisira nzira dzakasiyana-siyana: kuongorora kwemaziso kuti riiswe panzvimbo yaro, kuyedzwa kwemagetsi kwezvinhu nekubatana, uye kuyedzwa kwebasa rekuona maitiro. Kusarudza musanganiswa wakakodzera webhodhi rako nevhoriyamu ndiko kunoderedza mari inobhadharwa nekuvhara dambudziko. Gwaro iri rinotsanangura nzira huru dzekuyedzwa kwePCBA, kuti imwe neimwe inobata sei, kuti dzinobatana sei, uye kuti Highleap Electronics inodzishandisa sei.

1. Ndedzipi nzira huru dzekuedza PCBA?

Nzira huru dzekuongorora PCBA ndedze automated optical inspection (AOI), X-ray inspection, in-circuit test (ICT), flying-probe test, uye functional test, pamwe ne burn-in inowedzerwa kune zvigadzirwa zvinovimbika zvakanyanya. Dzinowira mumapoka matatu zvichienderana nezvadzinosimbisa: nzira dzekuongorora dzinoongorora kuti zvikamu zviripo uye zvakaiswa nemazvo, nzira dzemagetsi dzinoongorora kubatana uye kukosha kwezvikamu, uye nzira dzekushanda dzinoongorora kuti bhodhi rinoita basa raro zvechokwadi.

Hapana nzira imwe chete yakakwana — AOI inoona joint asi haigone kusimbisa kukosha kwe resistor, ICT inoyera kukosha asi haigone kusimbisa mabhutsu ebhodhi, uye bvunzo inoshanda inosimbisa kuti inofamba asi ingasaone joint yakaipa. Ndosaka kugadzirwa kwayo kuchibatanidza, nzira yakavakirwa pachirongwa chakajeka chekugadzira-kuyedza , uye mufananidzo wese ndewekuti bvunzo yakanaka yedunhu inosanganisa chii.

2. AOI neX-ray: kuongorora nzvimbo uye majoini akavanzwa

AOI inoshandisa makamera kuona kuti zvikamu zviripo, zvakaiswa zvakanaka, uye zvakasungirirwa zvakanaka pamajoini anoonekwa, ukuwo X-ray ichiongorora majoini asingaonekwe nemakamera - pasi peBGAs nedzimwe mapakeji ane magumo epasi. Pamwe chete vanowana nzvimbo uye zvikanganiso zvesolder zvinoumba chikamu chikuru chezvikanganiso zvekubatanidza, bvunzo yemagetsi isati yaitwa.

Kuongorora kwemaziso otomatiki kunoenzanisa bhodhi rega rega nereferensi inozivikanwa, zvichiratidza zvikamu zvisipo, zvikamu zvisina kumira zvakanaka kana kuti zvakaiswa pamatombo, polarity isiriyo, uye matambudziko anooneka ekusonesa nekukurumidza uye kugadzikana - zvakavimbika kupfuura kuongorora nemaoko. Kune majoini akavanzwa, kuongororwa kweX-ray kunotarisa kuburikidza nepakeji kuti vaone majoini ebhora uye kuona maburi ari pasi peBGAs, inova ndiyo chete nzira yekusimbisa kubatana ikoko kunze kwekuyedza kunoparadza. Nekuti AOI neX-ray hazvibatanidzi, hazvidi chinhu uye zvinoiswa kubva paprototype kusvika pavhoriyamu, zvichiita kuti zvive mutsetse wekutanga wekudzivirira mukuongorora kwemaziso otomatiki - kwakavakirwa pakudzora mhando.

3. ICT vs flying probe: kuyedzwa kwemagetsi kwekubatanidza

Bvunzo yeIn-circuit (ICT) inoshandisa chinhu chakagadzirwa nemagetsi kuti ione kana zvinhu zviri kuvhurwa, mashoti, uye zvikamu zviri kuvhurwa nekukurumidza, nepo bvunzo yeFlying-Probe ichiita zvakafanana nekuongorora maProbe anofamba uye pasina chinhu — kumhanya kwekutengesa pasina muripo wekushandisa maturusi. Zvese zvinoratidza kuti bhodhi rakagadzirwa nemazvo; rakakodzera rinoenderana nehuwandu:

• Bvunzo remudunhu inodzvanya mapini panet yega yega yakaongororwa kuburikidza nechishandiso chakatsaurirwa, ichiyera chikamu chimwe nechimwe nekubatana mumasekondi — yakanakira kugadzirwa kana mutengo wechishandiso waderedzwa, sezvakatsanangurwa muongororo iyi ye in-circuit test.
• Chinoongorora kubhururuka inofambisa ma probe mashoma kuti iite zviyero zvakafanana pasina chinhu, izvo zvinononoka pabhodhi asi zvakakwana kune ma prototypes uye vhoriyamu shoma apo dhizaini inogona kuchinja; ona kuti sei bvunzo yekubhururuka-yekuongorora anoshanda.
