The reflow soldering wopanga Shenzhen Chengyuan Makampani apeza zotsatirazi mavuto wamba pa reflow soldering kwa nthawi yaitali.Zotsatirazi ndi zina mwazovuta za soldering, komanso malingaliro okonzekera ndi kupewa:
1. Pamwamba pa olowa solder amaoneka frosted, crystallized kapena akhakula.
Kukonza: Mgwirizanowu ukhoza kukonzedwa potenthetsanso ndikuulola kuti uzizizire mosasokonezeka.
Katetezedwe: Sungani zolumikizira zogulitsira kuti mupewe zovuta
2. Kusungunuka kosakwanira kwa solder, kawirikawiri kumadziwika ndi malo ovuta kapena osagwirizana.Solder adhesion ndi osauka mu nkhani iyi, ndipo ming'alu akhoza kukula olowa pakapita nthawi.
Kukonza: Nthawi zambiri imatha kukonzedwa mwa kungotenthetsanso cholumikizira ndi chitsulo chotentha mpaka solder ikuyenda.Solder wowonjezera amathanso kukokedwa ndi nsonga yachitsulo.
Katetezedwe: Chitsulo chotenthetsera bwino chokhala ndi mphamvu zokwanira chithandiza kupewa izi.
3. Mgwirizano wa solder umatenthedwa.Chogulitsacho sichinayende bwino, ndipo zotsalira kuchokera kumoto wowotcha zikuyambitsa izi.
Kukonza: Malunjidwe a solder otenthedwa amatha kukonzedwa pambuyo poyeretsa.Chotsani kutentha kwamoto polemba mosamala ndi nsonga ya mpeni kapena mswachi.
Katetezedwe: Chitsulo chaukhondo, chotenthetsera bwino, kukonzekera bwino ndi kuyeretsa malo olumikizirana mafupa kumathandizira kuti mafupa asatenthedwe.
4. Malumikizidwewo onse adawonetsa zizindikiro zakunyowetsa matiresi osakwanira.Solder imanyowetsa zotsogolera bwino, koma sizipanga mgwirizano wabwino ndi mapepala.Izi zitha kukhala chifukwa cha bolodi lodetsedwa, kapena osawotcha mapepala ndi zikhomo.
Kukonza: Matendawa amatha kukonzedwanso poyika nsonga yachitsulo chotentha pansi pa mgwirizano mpaka solder ikuyenda kuphimba pad.
Katetezedwe: Kuyeretsa bolodi komanso kutenthetsa mapepala ndi mapini kungapewetse vutoli.
5. Chogulitsira chophatikiziracho sichinanyowetsenso piniyo ndipo idanyowetsa pang'ono padiyo.Pankhaniyi, palibe kutentha komwe kunagwiritsidwa ntchito pazikhomo, ndipo solder analibe nthawi yokwanira yoyenda.
Kukonza: Mgwirizanowu ukhoza kukonzedwa potenthetsanso ndikuyika solder yambiri.Onetsetsani kuti nsonga yachitsulo yotentha yakhudza pini ndi pad.
Katetezedwe: Ngakhale kutenthetsa mapini ndi mapepala amatha kupewa vutoli.
6. (Surface Mount) Tili ndi zikhomo zitatu za chigawo chokwera pamwamba pomwe solder sichimapita ku pad.Izi zimachitika chifukwa chotenthetsa pini, osati pad.
Kukonza: Kukonzedwa mosavuta ndikuwotcha pad ndi nsonga ya solder, kenako ndikuyika solder mpaka itasungunuka ndikusungunuka ndi solder pa pini.
7. Solder njala olowa solder chabe alibe zokwanira solder kuti solder.Mtundu woterewu wa solder umakhala ndi zovuta.
Konzani: Yatsaninso chophatikizira cha solder ndikuwonjezera solder kuti mugwirizane bwino.
8. Solder kwambiri
Konzani: Nthawi zambiri mumatha kujambula solder yochulukirapo ndi nsonga yachitsulo chotentha.Pazovuta kwambiri, solder sucker kapena waya wina wa solder amathandizanso.
9. Ngati waya wotsogolera ndi wautali kwambiri, pali chiopsezo chafupipafupi.Malumikizidwe awiri kumanzere ndi owopsa kukhudza.Koma yomwe ili kumanja ilinso yoopsa kwambiri.
Konzani: Dulani zolembera zonse pamwamba pa zolumikizira zogulitsira.
10. Zida ziwiri zogulitsira kumanzere zimasungunuka pamodzi, kupanga mgwirizano pakati pa awiriwo.
Konzani: Nthawi zina solder yochulukirapo imatha kutulutsidwa pokoka nsonga yachitsulo chotentha pakati pa ma solder awiri.Ngati pali solder yochuluka, solder sucker kapena solder wick ingathandize kuchotsa zowonjezera.
Katetezedwe: Kutsekera mlatho nthawi zambiri kumachitika pakati pa mfundo zowotcherera kwambiri.Gwiritsani ntchito solder yoyenera kuti mupange mgwirizano wabwino.
11. Mapadi ochotsedwa pa bolodi pamwamba.Izi zimachitika nthawi zambiri poyesa kuwononga chigawo chimodzi pa bolodi, mwina chifukwa cha kulephera kwa zomatira.
Izi zimachitika makamaka pamatabwa okhala ndi zigawo zopyapyala zamkuwa kapena osakutidwa ndi mabowo.
Izo sizingakhale zokongola, koma nthawi zambiri zimatha kukonzedwa.Chosavuta kukonza ndikupinda chowongolera pa waya wamkuwa womwe udalumikizidwabe ndikuwugulitsa monga momwe zasonyezedwera kumanzere.Ngati muli ndi chigoba cha solder pa bolodi lanu, chiyenera kupukutidwa mosamala kuti muwonetse mkuwa wopanda kanthu.
12. Kusokera solder spatter.Zogulitsa izi zimagwiridwa pa bolodi pokhapokha ndi zotsalira zomata.Ngati amasuka, akhoza kuchepetsa bolodi mosavuta.
Konzani: Chotsani mosavuta ndi nsonga ya mpeni kapena zomangira.
Ngati mavuto ali pamwambawa achitika, musachite mantha.Osapupuluma.Mavuto ambiri angathe kuthetsedwa ndi kuleza mtima.Ngati solder sikuyenda momwe mukufunira:
(1) Imani ndikusiya cholumikizira cha solder chizizire.
(2) Tsukani ndi kusita chitsulo chanu chogulitsira.
(3) Tsukani zotulukapo zilizonse zowotcha pamfundo.
(4) Kenako tenthetsaninso.
