PCBA processing kudzera mlingo kwenikweni mankhwala kuchokera m'mbuyomu ndondomeko yotsatira ndondomeko pakati pa nthawi chofunika kudya, ndiye nthawi yochepa, ndi apamwamba dzuwa, ndi apamwamba mlingo zokolola, pambuyo pa zonse, pokhapokha mankhwala anu alibe mavuto. kuyenda ku sitepe yotsatira.Ndi nkhaniyi tikambirana za m'badwo wa olowa solder mu PCBA kuwotcherera nsonga kukoka ndi yankho:
1. PCB dera bolodi mu preheating siteji kutentha ndi otsika kwambiri, preheating nthawi yochepa kwambiri, kotero kuti PCB ndi chigawo chipangizo kutentha ndi otsika, zigawo zikuluzikulu kuwotcherera ndi PCB kutentha mayamwidwe kwaiye otukukira nkhonya chizolowezi.
2. SMT makhazikitsidwe kuwotcherera kutentha ndi otsika kwambiri kapena conveyor lamba liwiro ndi mofulumira kwambiri, kotero kuti mamasukidwe akayendedwe a solder sungunuka ndi yaikulu kwambiri.
3. electromagnetic mpope wave soldering machine wave length ndi wokwera kwambiri kapena pini ndi yayitali kwambiri, kotero kuti pansi pa pini sungagwirizane ndi nsonga yoweyula.Chifukwa makina opangira ma electromagnetic pump wave ndi obowo, makulidwe a dzenjelo ndi 4 ~ 5mm.
4. Kusayenda bwino.
5. Zigawo za katiriji za DIP zimatsogolera m'mimba mwake ndi chiŵerengero cha dzenje la cartridge sizolondola, dzenje la cartridge ndi lalikulu kwambiri, kuyamwa kwakukulu kwa pad kutentha.
The pamwamba vuto mfundo ndi zinthu zofunika kwambiri mu m'badwo wa solder olowa kukoka nsonga, kotero tiyenera kupanga lolingana kukhathamiritsa ndi kusintha kwa mavuto pamwamba smt makhazikitsidwe processing, kuthetsa vuto zisanachitike, kuonetsetsa mankhwala zokolola ndi liwiro loperekera.
1. Tin yoweyula kutentha kwa 250 ℃ ± 5 ℃, kuwotcherera nthawi 3 ~ 5s;kutentha ndi pang'ono m'munsi, ndi conveyor lamba liwiro kuchepetsa ena.
2. Kutalika kwa mafunde nthawi zambiri kumayendetsedwa pa 2/3 ya makulidwe a bolodi losindikizidwa.Kupanga mapini olowetsedwa kumafuna mapini azinthu kuti awonekere ku zosindikizidwa
3. Board soldering pamwamba 0.8mm ~ 3mm.
4. Kusintha kwa kusinthasintha.
5. Bowo la dzenje la cartridge ndi 0.15 ~ 0.4mm lalikulu kuposa kutsogolera m'mimba mwake (kutsogola bwino kumatenga mzere wapansi, kutsogola kwakuda kumatenga malire apamwamba).
Mawonekedwe a NeoDen IN6 Reflow Oven
1. Full convection, ntchito yabwino kwambiri ya soldering.
2. 6 zone kapangidwe, kuwala ndi yaying'ono.
3. Kuwongolera kwanzeru ndi sensor yotentha kwambiri, kutentha kumatha kukhazikika mkati mwa + 0.2 ℃.
4. Dongosolo losefera utsi loyambira lomwe limapangidwira, mawonekedwe owoneka bwino komanso okonda zachilengedwe.
5. Kutentha kwa chitetezo cha kutentha, kutentha kwa casing kumatha kuwongoleredwa mkati mwa 40 ℃.
6. Mphamvu zapakhomo, zosavuta komanso zothandiza.
