Momwe mungagwiritsire ntchito solder phala mu PCBA?
(1) Njira yosavuta yowonera kukhuthala kwa phala la solder: Sakanizani phala la solder ndi spatula kwa mphindi 2-5, tengani phala laling'ono ndi spatula, ndikusiya phala la solder ligwere mwachibadwa.The mamasukidwe akayendedwe ndi zolimbitsa;ngati phala la solder silikuchoka konse, kukhuthala kwa phala la solder ndikwambiri;ngati phala la solder limangotuluka mwachangu, kukhuthala kwa solder phala kumakhala kochepa kwambiri;
(2) Kusungirako phala la solder: firiji mu mawonekedwe osindikizidwa pa kutentha kwa 0 ° C mpaka 10 ° C, ndipo nthawi yosungiramo nthawi zambiri imakhala miyezi 3 mpaka 6;
(3) Pambuyo pochotsa phala la solder mufiriji, liyenera kutenthedwa kutentha kwa maola oposa 4 musanagwiritse ntchito.Njira yotenthetsera singagwiritsidwe ntchito kubwerera kutentha;mutatha kutenthetsa phala la solder, liyenera kugwedezeka (monga kusakaniza ndi makina, kuyambitsa 1-2 Mphindi, kugwedeza ndi dzanja kumafunika kugwedezeka kwa mphindi zoposa 2) musanagwiritse ntchito;
(4) Kutentha kozungulira kwa solder phala kusindikiza kuyenera kukhala 22℃～28℃, ndi chinyezi kuyenera kukhala pansi pa 65%;
(5) Kusindikiza kwa solder
1. Pamene kusindikiza solder phala, Ndi bwino kugwiritsa ntchito solder phala ndi zitsulo zili 85% mpaka 92% ndi moyo utumiki wa maola oposa 4;
2. Kuthamanga Kusindikiza Panthawi yosindikiza, liwiro la kuyenda kwa squeegee pa template yosindikizira ndilofunika kwambiri, chifukwa phala la solder limafuna nthawi yopukutira ndikulowa mu dzenje lakufa.Zotsatira zake zimakhala bwino pamene phala la solder likugudubuza mofanana pa stencil.
3. Kusindikiza kukakamiza Kusindikiza kumayenera kugwirizanitsidwa ndi kuuma kwa squeegee.Ngati kupanikizika kuli kochepa kwambiri, squeegee sichidzayeretsa phala la solder pa template.Ngati kupanikizika kuli kwakukulu kwambiri kapena squeegee ndi yofewa kwambiri, squeegee idzamira ku template.Dulani phala la solder pa dzenje lalikulu.Njira yoyeserera yakukakamiza: Gwiritsani ntchito chopukusira pa template yachitsulo.Kuti muthe kukakamiza koyenera, yambani kugwiritsa ntchito 1 kg yamphamvu pa mamilimita 50 aliwonse a kutalika kwa scraper.Mwachitsanzo, 300 mm scraper imagwiritsa ntchito kukakamiza kwa 6 kg kuti pang'onopang'ono kuchepetsa kupanikizika.Mpaka solder phala ayamba kukhalabe pa Chinsinsi ndipo si zikande bwino, ndiye pang'onopang'ono kuwonjezera mavuto mpaka solder phala basi zikande.Panthawi imeneyi, kupanikizika kuli koyenera.
4. Njira yoyendetsera kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake ndi Kuphatikiza kwa scraper) ndi njira yoyenera (kuyika bwino, kuyeretsa ndi kupukuta).Malinga ndi mankhwala osiyanasiyana, anapereka lolingana ndondomeko yosindikiza magawo mu pulogalamu yosindikiza, monga kutentha ntchito, kuthamanga ntchito, squeegee liwiro, demoulding liwiro, basi Chinsinsi kuyeretsa mkombero, etc. Pa nthawi yomweyo, m`pofunika kupanga ndondomeko okhwima. dongosolo kasamalidwe ndi ndondomeko ndondomeko.
① Gwiritsani ntchito phala la solder mkati mwa nthawi yovomerezeka molingana ndi mtundu womwe wasankhidwa.Phala la solder liyenera kusungidwa mufiriji mkati mwa sabata.Iyenera kuikidwa kutentha kwa maola oposa 4 musanagwiritse ntchito, ndiyeno chivindikirocho chikhoza kutsegulidwa kuti chigwiritsidwe ntchito.Phala logwiritsidwa ntchito la solder liyenera kusindikizidwa ndikusungidwa padera.Kaya khalidwe ndiloyenera.
② Asanayambe kupanga, wogwiritsa ntchito amagwiritsa ntchito mpeni wapadera wosapanga dzimbiri kuti agwedeze phala la solder kuti lifanane.
③ Pambuyo kusanthula koyamba kusindikiza kapena kusintha zida pa ntchito, solder phala makulidwe tester adzagwiritsidwa ntchito kuyeza kusindikiza makulidwe a solder phala.Mfundo zoyesera zimasankhidwa pa mfundo za 5 pamtunda woyesera wa bolodi losindikizidwa, kuphatikizapo kumtunda ndi kumunsi, kumanzere ndi kumanja ndi pakati, ndikulemba mfundozo.Kuchuluka kwa phala la solder kumayambira -10% mpaka +15% ya makulidwe a template.
④ Pakupanga, 100% kuyang'anira kumachitika pamtundu wosindikiza wa solder phala.Zomwe zili zazikulu ndizoti mtundu wa solder phala uli wathunthu, ngati makulidwe ake ndi yunifolomu, komanso ngati pali solder phala nsonga.
⑤ Yeretsani template molingana ndi zomwe zimafunikira mukamaliza ntchito.
⑥ Pambuyo poyesera kusindikiza kapena kulephera kusindikiza, phala la solder pa bolodi losindikizidwa liyenera kutsukidwa bwino ndi zipangizo zoyeretsera zowonongeka ndi zouma, kapena kutsukidwa ndi mowa ndi mpweya wothamanga kwambiri kuti phala la solder pa bolodi lisayambike. kugwiritsidwanso ntchito.Mipira ya Solder ndi zochitika zina pambuyo pa reflow soldering
NeoDen imapereka mayankho athunthu a mzere wa SMT, kuphatikiza uvuni wa SMT reflow, makina osokera, makina osankha ndi malo, makina osindikizira a solder, PCB loader, PCB unloader, chip mounter, SMT AOI makina, makina a SMT SPI, makina a SMT X-Ray, Zida zopangira msonkhano wa SMT, Zida zopangira PCB SMT zida zosinthira, ndi zina zilizonse makina a SMT omwe mungafune, chonde titumizireni kuti mumve zambiri:
