Kugulitsa pamanja ndi njira yodziwika kwambiri mumizere ya SMT.Koma njira yowotcherera iyenera kulabadira njira zina zotetezera kuti zigwire ntchito bwino.
Ogwira ntchito ayenera kulabadira mfundo izi:
1. Chifukwa cha mtunda wa chitsulo chosungunuka 20 ~ 30cm pa ndende ya zinthu za mankhwala kusiyana ndi mtengo wovomerezeka ndi wochepa kwambiri, kotero pamene kuwotcherera kuyenera kukhala ndi machitidwe oyenerera opangira opaleshoni, nsonga ya mutu wa chitsulo chosungunuka kuchokera ku nsonga ya chitsulo. Opaleshoni mphuno kukhala osachepera 20cm pamwamba pa ntchito kuwongola m'chiuno, pachifuwa atakhala, musaweramitse ntchito.
2. Kutsogolera sikumasanduka nthunzi, koma chifukwa ntchito yogwiritsira ntchito chala chachikulu ndi chala chakutsogolo kukatsina waya wogulitsira, chitsulo chosungunula chopangidwa ndi microscopic chimamamatira ku chala, onetsetsani kuti mwakhala ndi chizolowezi chosamba m'manja musanadye.
3. ndimakina odziyimira pawokhakwa smt processing,Makina owotcherera a SMTzinapanga utsi wambiri utakuta m'nyumba.Panthawi imeneyi, mukhoza choyamba kutsegula mpweya chipangizo, ndiyeno kuyamba ntchito.
4. Chifukwa kukonza ndi kufunika disassemble waya welded, nthawi zina chifukwa elasticity wa waya ndi brazing chuma kugwa kunja.Pini yoboola imatha kuvulaza mwangozi, chifukwa chake muyenera kuvala magalasi oteteza mukamagwira ntchito, ndipo izi ziyenera kuchitika mwamphamvu.
5. Palibe kuphulika kwa zinthu zowomba kuyenera kuloledwa pa benchi yogwirira ntchito ndi malo ozungulira kuti ateteze zinthu zowotcha kuti zisamamatire ku thupi kapena zovala.Yeretsani kamodzi patsiku kuti ntchito yowotcherera igwire ntchito pamalo aukhondo.
6. Chifukwa cha ntchito soldering flux kapena zosungunulira pamene kwambiri kuwotcherera, ndi mphamvu soldering chitsulo anaika pa workbench, pa kaonedwe ka kupewa moto, ayenera kukhala ndi soldering chitsulo choyikapo, soldering chitsulo kuti mwaukhondo anaika, kuchita. ndicholinga choti.
7. Anthu ena nthawi zambiri amamatira muzitsulo zazitsulo pazitsulo zowonjezera zowonongeka zomwe zimaponyedwa pansi, zomwe zimakhala zosavuta kuvulaza ena, komanso zimadetsa pansi.Chifukwa chake, choyikapo chitsulo chosungunuka chimatha kuyikidwa pa chotsukira mutu wachitsulo chotsuka, kuti mutsuka.Kapena ikani chonyowa chonyowa patebulo la opaleshoni, lingagwiritsidwenso ntchito kupukuta solder pazitsulo zazitsulo.
8. Kuphatikiza apo, mu nyengo yowuma yowotcherera, mutha kuvala zibangili zotsutsana ndi ma static, kuvala zovala zantchito zotsutsana ndi static.
