PambuyoKusintha kwamitengo ya SMTtidzakumana ndi zovuta zina, zolakwika za SMT processing soldering izi zidzakhudza mwachindunji kapena m'njira zina ubwino wa mankhwala.Zochitika zolakwika izi ndizowoneka bwino kwa ogwiritsira ntchito a SMT pazowunikira zolakwika pakuwongolera zigamba, kuti apereke chizindikiro chamakampani kuti apititse patsogolo kupanga ndikugwiritsa ntchito dzina loyipa.Mu kwenikweni chigamba processing kwa zochitika zosalongosoka wapezeka, ndi kukhala mosamalitsa rework kapena kukonza mankhwala.Ndiye tiyenera kumvetsetsa bwanji kuti tidziwe choyipacho?
Dinani apa kuti muwerenge zotsatirazi:
1. (ngakhale malata) SMT processing kuwotcherera ngakhale malata amatchedwanso malata mlatho, pakati chigawo malekezero, pakati moyandikana solder mfundo zigawo zikuluzikulu, komanso olowa solder ndi mawaya moyandikana, perforations, etc. sayenera kulumikizidwa ndi gawo la solder yolumikizidwa pamodzi, SMT processing industry yotchedwa even malata.
2. (chipilala) tombstone, wotchedwanso Manhattan chodabwitsa, amatanthauza awiri soldering mapeto a zigawo za chip, pambuyo reflow soldering, mmodzi wa soldering mapeto kutali ndi pedi pamwamba chigawo chonse anali oblique ndi woongoka.Makampani a SMT amatchedwa chipilala.
3. (mbali kuima) Chip chigawo mbali ndi PCB PAD kukhudzana chodabwitsa.makampani a SMT amatchedwa side stand.
4. (kuchotsera) zigawo mu malo opingasa kusuntha, zomwe zimapangitsa kuti mapeto a solder kapena pini asagwirizane ndi PCB pad.
5. (otsutsa-woyera) chidutswa cha chigawo kutsogolo kwa PCB, pansi mbali mmwamba chodabwitsa.
6. (mikanda ya malata) mu reflow soldering, zomangika ku chidutswa cha mbali mbali kapena omwazikana mu solder olowa, kuwonjezera ting'onoting'ono mikanda solder.
7. (cold soldering) reflow chosakwanira chodabwitsa, solder safika kusungunuka kutentha kapena kuwotcherera kutentha sikokwanira, kotero kuti olimba pamaso pa nyongolotsi ndi kutuluka, palibe mapangidwe zitsulo aloyi wosanjikiza wosanjikiza, kotero kuti onse. kapena gawo la solder mu dziko lopanda crystalline ndikungomanga pamwamba pazitsulo zomwe zimagulitsidwa.
8. (pachimake suction) solder kuchokera padi m'mphepete mwa pini kukwera ku pini ndi thupi la chip, zomwe zimapangitsa kuti pakhale matope osakwanira kapena opanda kanthu pazitsulo zogulitsira.
9. (zosintha) zimatanthawuza polarity ya zigawo pambuyo kuwotcherera, polarity wa malangizo a zofunika kwenikweni malangizo si zogwirizana.
10. (kuwira) solder mu solidification wa mpweya pamaso kulephera kuthawa mu nthawi, mapangidwe dzenje chodabwitsa mkati solder olowa.
11. (Pinhole) mu solder olowa pamwamba kupanga mabowo ngati singano.
12. (fissure) zolumikizira zogulitsa chifukwa cha kupsinjika kwamakina kapena kupsinjika kwamkati komwe kumachitika chifukwa cha zochitika zamagulu osweka a solder.
13. (nsonga ya malata) kuwotcherera panja yotulukira kunja ngati singano kapena malata osongoka.
14. (zambiri malata) soldering pa solder zambiri kuposa kuchuluka yachibadwa kufunika, kotero kuti n'zovuta kuona ndondomeko ya soldered mbali kapena solder kupanga mulu ozungulira.
15. (lotseguka solder) chigawo zikhomo / solder mapeto a zonse kunja kapena kutali ndi ziwiya lolingana, osati chifukwa soldering.
16. (woyera mawanga) anaonekera mu gawo lapansi laminated mkati chodabwitsa, mmene galasi ulusi mu kotenga nthawi ndi yopingasa kuwoloka ndi utomoni kulekana.Chodabwitsa ichi chikuwonetsedwa ngati mawanga oyera kapena gawo lapansi pansi pa "woboola pakati", nthawi zambiri zimagwirizanitsidwa ndi mapangidwe a nkhawa chifukwa cha kutentha.
17. (kuwotcherera imvi) chifukwa cha kutentha kwakukulu kwa kuwotcherera, kutuluka kwa mpweya wambiri ndi kuwotcherera mobwerezabwereza, etc., pamwamba pa weld ndi imvi, kristalo wa solder ndi wotayirira, porous ndi slag.
Zhejiang NeoDen Technology Co., LTD., yomwe idakhazikitsidwa mu 2010, ndi katswiri wopanga makina opangira ma SMT ndi malo, uvuni wa reflow, makina osindikizira a stencil, chingwe chopangira SMT ndi Zida zina za SMT.Tili ndi gulu lathu la R & D ndi fakitale yathu, kugwiritsa ntchito mwayi wathu olemera odziwa R&D, kupanga ophunzitsidwa bwino, adapambana mbiri yabwino kuchokera kwamakasitomala padziko lonse lapansi.
Tili pamalo abwino osati kukupatsirani makina apamwamba kwambiri a pnp, komanso zabwino kwambiri pambuyo pa malonda.
Mainjiniya ophunzitsidwa bwino adzakupatsani chithandizo chilichonse chaukadaulo.
Mainjiniya 10 amphamvu pambuyo pogulitsa gulu lantchito amatha kuyankha mafunso ndi mafunso amakasitomala mkati mwa maola 8.
Mayankho aukadaulo atha kuperekedwa mkati mwa maola 24 tsiku lantchito komanso tchuthi.
