PCBA bolodi ntchito ndondomeko, nthawi zambiri padzakhala chodabwitsa cha PAD, makamaka PCBA bolodi kukonza nthawi, pamene ntchito chitsulo soldering, n'zosavuta kwambiri mzere PAD kuchoka chodabwitsa, PCB fakitale ayenera kukhala mmene kulimbana ndi?M'nkhani ino, pali zifukwa zingapo zomwe zimayambitsa vutoli.
1. Mavuto amtundu wa mbale
Chifukwa cha mkuwa atavala laminate mbale mkuwa zojambulazo ndi epoxy utomoni pakati pa utomoni zomatira zomatira kumamatira ndi osauka, ndiye, ngakhale dera lalikulu la zojambulazo mkuwa wa bolodi mkuwa zojambulazo pang`ono usavutike mtima kapena pansi mawotchi mphamvu, ndi kwambiri. zosavuta kupatukana ndi utomoni wa epoxy zomwe zimapangitsa kuti pads kuzimitsidwa kapena zojambulazo zamkuwa ndi zina.
2. Zotsatira za zinthu zosungirako bolodi la dera
Kukhudzidwa ndi nyengo kapena kusungidwa kwa nthawi yayitali pamalo a chinyezi, kuyamwa kwa chinyezi kwa PCB board kumabweretsa chinyezi chochulukirapo, kuti mukwaniritse zomwe mukufuna, kuwotcherera patch kubwezera kutentha komwe kumachotsedwa chifukwa cha evaporation, kutentha kwa kuwotcherera ndi nthawi. ayenera anawonjezera, zinthu kuwotcherera ngati sachedwa kuchititsa dera bolodi mkuwa zojambulazo ndi epoxy utomoni delamination, kotero PCB processing chomera ayenera kulabadira chinyezi cha chilengedwe posunga bolodi PCB.
3. Mavuto owotcherera chitsulo
General PCB bolodi kumamatira akhoza kukumana kuwotcherera wamba, sipadzakhala PAD kuchoka chodabwitsa, koma zinthu zamagetsi zambiri zotheka kukonza, kukonza zambiri ntchito soldering chitsulo kuwotcherera kukonza, chifukwa m`dera kutentha kwa soldering chitsulo zambiri kufika 300- 400 ℃, chifukwa m'deralo kutentha yomweyo mkulu wa PAD, kuwotcherera utomoni pansi pa zojambulazo mkuwa ndi kutentha kwapamwamba kugwa, maonekedwe a pedi.Soldering chitsulo dismantling n'zosavuta mwangozi soldering chitsulo mutu pa thupi mphamvu ya kuwotcherera chimbale, amenenso kumabweretsa chifukwa cha PAD.
Makhalidwe aNeoDen IN12C Refow Oven
1. Makina opangira kuwotcherera a fume filtration, kusefera koyenera kwa mpweya woipa, mawonekedwe okongola komanso chitetezo cha chilengedwe, chogwirizana kwambiri ndi kugwiritsa ntchito malo apamwamba kwambiri.
2. Dongosolo lowongolera lili ndi mawonekedwe a kuphatikiza kwakukulu, kuyankha kwanthawi yake, kulephera kochepa, kukonza kosavuta, etc.
3. Kutentha kwapadera kwa module yotenthetsera, yokhala ndi kutentha kwapamwamba kwambiri, kutentha kwa yunifolomu m'dera la chiwongoladzanja chotenthetsera, kutentha kwakukulu kwa chiwongoladzanja cha kutentha, kutsika kwa mphamvu ndi zina.
4. Mapangidwe oteteza kutentha kwa kutentha, kutentha kwa chipolopolo kumatha kuyendetsedwa bwino.
5. Ikhoza kusunga mafayilo 40 ogwira ntchito.
6. Kufikira 4-njira zenizeni nthawi chiwonetsero cha PCB bolodi pamwamba kuwotcherera kutentha pamapindikira.
7. opepuka, miniaturization, akatswiri opanga mafakitale, mawonekedwe osinthika ogwiritsira ntchito, aumunthu ambiri.
8. Kupulumutsa mphamvu, kugwiritsa ntchito mphamvu zochepa, mphamvu zochepa zamagetsi, magetsi wamba wamba amatha kukumana ndi ntchito, poyerekeza ndi zinthu zofanana pachaka zimatha kupulumutsa ndalama zamagetsi ndikugula 1 unit ya mankhwalawa.
