PCBA chigamba processing ndondomeko ndi zovuta kwambiri, kuphatikizapo PCB bolodi kupanga ndondomeko, chigawo chogula ndi kuyendera, SMT chigamba msonkhano, DIP pulagi-mu, PCBA kuyezetsa ndi njira zina zofunika.Pakati pawo, PCBA mayeso ndi zofunika kwambiri ulamuliro khalidwe ulalo mu lonse PCBA processing ndondomeko, amene amatsimikiza ntchito yomaliza ya mankhwala.Ndiye mawonekedwe a mayeso a PCBA ndi chiyani? Mayeso a PCBA makamaka akuphatikizapo: mayeso a ICT, mayeso a FCT, mayeso okalamba, kuyezetsa kutopa, kuyesa chilengedwe movutikira mitundu isanu iyi.

1, Mayeso a ICT makamaka amaphatikizapo kuzungulira pa-off, ma voliyumu ndi mafunde apano ndi mafunde a curve, matalikidwe, phokoso, ndi zina.

2, mayeso a FCT amayenera kuchita kuwombera kwa pulogalamu ya IC, kutengera momwe gulu lonse la PCBA limagwirira ntchito, kupeza zovuta mu Hardware ndi mapulogalamu, ndikukhala ndi zida zofunikira zopangira chigamba ndi choyikapo mayeso.

3, kuyezetsa kutopa makamaka kuyesa PCBA bolodi, ndi kuchita mkulu-pafupipafupi ndi yaitali ntchito ntchito, kuona ngati kulephera kumachitika, kuweruza Mwina kulephera mayeso, ndi ndemanga ntchito ntchito ya PCBA. bolodi muzinthu zamagetsi.

4, mayeso mu chilengedwe nkhanza makamaka kuvumbula PCBA bolodi kutentha, chinyezi, dontho, splash, kugwedera mtengo malire, kupeza zotsatira mayeso a zitsanzo mwachisawawa, kuti atsimikizire kudalirika kwa gulu lonse PCBA. gulu.

5, ukalamba mayeso makamaka mphamvu PCBA bolodi ndi mankhwala pakompyuta kwa nthawi yaitali, kusunga ntchito ndi kuona ngati pali kulephera, pambuyo ukalamba mayeso mankhwala pakompyuta akhoza kugulitsidwa mu batches.PCBA ndondomeko zovuta, kupanga ndi processing ndondomeko, pakhoza kukhala mavuto osiyanasiyana chifukwa zida zosayenera kapena ntchito, sangatsimikizire kuti mankhwala opangidwa ndi oyenerera, choncho m'pofunika kuchita kuyezetsa PCB kuonetsetsa kuti mankhwala sadzakhala ndi mavuto khalidwe.

Momwe mungayesere pcba

PCBA mayeso wamba njira, pali makamaka zotsatirazi:

1. Mayeso a pamanja

Kuyesa pamanja ndikudalira mwachindunji masomphenya kuyesa, kudzera m'masomphenya ndi kuyerekezera kutsimikizira kukhazikitsidwa kwa zigawo pa PCB, ukadaulo uwu umagwiritsidwa ntchito kwambiri.Komabe, chiwerengero chachikulu ndi zigawo zing'onozing'ono zimapangitsa kuti njirayi ikhale yochepa komanso yochepa.Komanso, zolakwika zina zogwirira ntchito sizidziwika mosavuta ndipo kusonkhanitsa deta kumakhala kovuta.Mwanjira imeneyi, njira zoyesera zamaluso ndizofunikira.

2, Automatic Optical inspection (AOI)

Kuzindikira kodziwikiratu kwamaso, komwe kumadziwikanso kuti kuyezetsa masomphenya basi, kumachitika ndi chowunikira chapadera, chomwe chimagwiritsidwa ntchito isanayambe komanso itatha reflux, ndipo polarity ya zigawo zake ndizabwinoko.Njira yosavuta yotsatirira matenda ndi njira yodziwika bwino, koma njira iyi ndiyabwino pakuzindikiritsa dera lalifupi.

3, kuwuluka singano makina mayeso

Kuyesa kwa singano kwadziwika kwambiri zaka zingapo zapitazi chifukwa cha kupita patsogolo kwa makina olondola, kuthamanga, komanso kudalirika.Kuonjezera apo, kufunikira kwamakono kwa dongosolo loyesera lokhala ndi kutembenuka kwachangu ndi luso lopanda jig lofunika pakupanga Prototype ndi kupanga ma volume ochepa kumapangitsa kuyesa singano yowuluka kukhala yabwino kwambiri.4.Kuyesa kogwira ntchito

Iyi ndi njira yoyesera ya PCB inayake kapena gawo linalake, lomwe limapangidwa ndi zida zapadera.Pali mitundu iwiri ikuluikulu yoyezetsa ntchito: Final Product Test ndi Hot Mock-up.

5. Manufacturing Defect Analyzer (MDA)

Ubwino waukulu wa njira yoyeserayi ndi mtengo wotsika wakutsogolo, kutulutsa kwakukulu, kutsata matenda osavuta komanso kuthamanga kwafupipafupi komanso kuyezetsa dera lotseguka.Choyipa ndichakuti kuyesa kwa magwiridwe antchito sikungachitike, nthawi zambiri pamakhala palibe chowonetsa, mawonekedwe ayenera kugwiritsidwa ntchito, ndipo mtengo wake woyeserera ndi wokwera.

zida zoyeserera za pcba

Zida zoyeserera za PCBA zodziwika bwino ndi: ICT tester pa intaneti, mayeso a FCT ndi mayeso okalamba.

1, woyesa pa intaneti wa ICT

ICT ndiyoyesera pa intaneti, yomwe ili ndi ntchito zambiri komanso yosavuta kugwiritsa ntchito.ICT yodziwikiratu pa intaneti yowunikira makamaka ndiyowongolera njira zopangira, imatha kuyeza kukana, mphamvu, inductance, dera lophatikizika.Ndizothandiza makamaka pozindikira dera lotseguka, dera lalifupi, kuwonongeka kwa gawo, ndi zina zambiri, malo olakwika olondola, kukonza kosavuta.

2. Kuyesa kwa FCT

FCT ntchito mayeso ndi kupereka kayeseleledwe ntchito chilengedwe monga chisangalalo ndi katundu kwa bolodi PCBA, ndi kupeza magawo osiyanasiyana boma la bolodi kuyesa ngati magawo zinchito za bolodi kukwaniritsa zofunika kamangidwe.Zinthu zoyezera ntchito za FCT makamaka zimaphatikiza ma voltage, apano, mphamvu, mphamvu, ma frequency, kuzungulira kwa ntchito, kuwala ndi mtundu, kuzindikira mawonekedwe, kuzindikira mawu, kuyeza kutentha, kuyeza kupanikizika, kuwongolera koyenda, FLASH ndi EEPROM kuyatsa.

3. Mayeso okalamba

Kuyesa kukalamba kumatanthawuza njira yofananizira zinthu zosiyanasiyana zomwe zimakhudzidwa ndi momwe zinthu zimagwiritsidwira ntchito kuti akwaniritse zoyeserera zofananira.The PCBA gulu la zinthu zamagetsi angagwiritsidwe ntchito kwa nthawi yaitali kuyerekezera ntchito kasitomala, athandizira / linanena bungwe kuyezetsa kuonetsetsa kuti ntchito yake akukumana kufunika msika.

Izi mitundu itatu ya zida mayeso ndi wamba mu ndondomeko PCBA, ndi PCBA kuyezetsa mu ndondomeko PCBA processing akhoza kuonetsetsa kuti bolodi PCBA kuperekedwa kwa kasitomala akukumana zofuna kasitomala kamangidwe ndi kuchepetsa kwambiri mlingo kukonza.
