Njira zisanu ndi imodzi za SMT Patch Component Disassembly(II)

IV.Njira yothetsera vutoli
Njirayi ndi yoyenera disassembly of chip - mounted integrated circuits.Gwiritsani ntchito waya wa enameled wa makulidwe oyenera, ndi mphamvu zina, kudzera mumpata wamkati wa pini yophatikizidwa.Mapeto amodzi a waya wa enameled amakhazikika m'malo mwake ndipo mapeto ena amagwiridwa ndi dzanja.Pamene solder pa pini ya Integrated dera amasungunuka.Kokani waya wa enameled kuti "mudule" cholumikizira chogulitsira ndipo zikhomo za IC zimasiyanitsidwa ndi PCB.
 
V. Air gun soldering iron yofananira njira
Sinthani kutentha kwa mfuti ya mpweya mpaka kufika madigiri oposa 500, voliyumu ya mpweya wochepa, kutentha kosalekeza kwa mikwingwirima iwiri ya malata, solder imasungunuka patatha masekondi oposa khumi, kuchotsa mosavuta ndi ma tweezers, koma njira iyi ndi yosavuta. kukhudza dera lozungulira, ntchito mosamala.Chotsatira ndi monga chipangizo chatsopano, choyamba ndi rosin madzi besmear ndi pa solder waya, kapena ntchito rosin ufa anamwazikana pa zomangira PAD, ndi woyera kuwotcherera zitsulo-chala Kutentha zitsulo mbale kutsogolera chonyowa kuwala, kutsogolera malata ndi osamveka bwino, pamene kuwotcherera mutu Kutentha waya, yesetsani kusuntha cha m'mphepete, pangani otsala kutsogolera malata pa kuwotcherera mbale zotumphukira.Gwiritsani ntchito chida chaching'ono kuti mutsuke zinyalala za rosin pa pedi lead.Tengani chidutswa cha IC yatsopano, mothandizidwa ndi rosin ku malata pa IC pini, pini yonyowa kuwala popanda burr, IC ili pa kompyuta, dinani ndi chala, pangani IC pini tambala pang'ono, ikani IC ndi mbale yowotcherera. , yokhala ndi pini yowongoka ya IC malo apakati, maso osawoneka bwino abwenzi amatha kugwiritsa ntchito galasi lokulitsa kuti awonere, Pambuyo poyika chitsulo chowotcherera chitha kugwiritsidwa ntchito kutenthetsa malata pamphepete mwa pad, mutu wachitsulo wosungunulira umakankhira pini ya IC mkati. tini itasungunuka, kotero kuti piniyo imapanga ngodya yolondola pa pad.M`pofunika kuwotcherera anayi diagonal ngodya choyamba, kupuma pambuyo kuwotcherera, ndiyeno kuwotcherera mapazi ena.Pambuyo pa kuwotcherera, galasi lokulitsa lingagwiritsidwe ntchito kuyang'anitsitsa, ndipo malata ochepa amatha kugwiritsidwa ntchito m'malo oipa.

VI.Kuchotsa njira ya malata absorber
Pali mitundu iwiri ya chitsulo chosungunulira ndi tin absorber.Mukamagwiritsa ntchito chowumitsira malata wamba, ndodo ya pisitoni ya chowumitsira malata imatsitsidwa.Pamene mgwirizano wa solder wa chitsulo chosungunula chamagetsi chasungunuka, pakamwa pakamwa pazitsulo zotsekemera zimakhala pafupi ndi malo osungunuka, ndipo batani lotulutsa la tini limakanizidwa.Ndodo ya pisitoni ya chowumitsira malata imatulukanso ndikuyamwa malata osungunukawo.Kubwerezedwa kangapo, akhoza kuchotsedwa pa bolodi losindikizidwa.

NeoDen imapereka mayankho athunthu amizere ya SMT, kuphatikiza uvuni wa SMT reflow, makina otenthetsera, makina osankha ndi malo, chosindikizira cha solder, uvuni wa Reflow,Pulogalamu ya PCB, PCB unloader,chokwera chip, makina a SMT AOI, makina a SMT SPI, makina a SMT X-Ray, zida zolumikizirana za SMT, zida zopangira PCB Zida za SMT zosinthira, ndi zina zilizonse makina a SMT omwe mungafune, chonde titumizireni kuti mudziwe zambiri:
