Malo ogwiritsira ntchito zida zowotchera ma wave
1. Kutentha kwa kutentha kwa zida zowotchera mafunde

Kutentha kwa soldering kwa zida zopangira ma wave soldering kumatanthawuza kutentha kwa ukadaulo wa soldering pachimake potulutsa nozzle.Nthawi zambiri, kutentha ndi 230-250 ℃, ndipo ngati kutentha kuli kotsika kwambiri, zolumikizira zogulitsira zimakhala zolimba, zokoka komanso zosawala.Zimayambitsa ngakhale kuwotcherera pafupifupi ndi incandescence zabodza;ngati kutentha kuli kwakukulu, ndikosavuta kufulumizitsa makutidwe ndi okosijeni, kusokoneza bolodi losindikizidwa, ndikuwotcha zigawo zonse.Kusintha kwa kutentha kuyenera kusinthidwa molingana ndi zinthu ndi kukula kwa bolodi losindikizidwa, kutentha kozungulira, ndi liwiro la lamba wotumizira.

2. Chotsani malata mu ng'anjo yowotchera yoweyula panthawi yake

Tini mu bafa ya malata a zida zowotchera mafunde amatha kupanga ma oxides akakumana ndi mpweya kwa nthawi yayitali.Ngati ma oxide achuluka kwambiri, amawapopera pa bolodi losindikizidwa ndi malata pansi pa mpope.Zolumikizana pang'ono za solder mu luster.Zimayambitsa zolakwika monga kuwongolera kwa slag ndi kulumikiza.Choncho, m'pofunika kuchotsa oxides nthawi zonse (nthawi zambiri maola 4 aliwonse).Ma Antioxidants amathanso kuwonjezeredwa ku solder yosungunuka.Izi sizimangoletsa makutidwe ndi okosijeni komanso zimachepetsa oxide kukhala malata.

3. Kutalika kwa chiwombankhanga cha zida zowotchera

Kutalika kwa mafunde a zida zowotchera mafunde kumasinthidwa bwino kukhala 1/2-1/3 ya makulidwe a bolodi losindikizidwa.Ngati chiwombankhangacho chili chotsika kwambiri, chimayambitsa kutayikira kwa solder ndi kupachika malata, ndipo ngati chiwombankhanga chili chokwera kwambiri, chimayambitsa kuchulukitsidwa kwa malata.Zigawo zotentha kwambiri.

4. Kutumiza liwiro la zida zowotchera mafunde

Kuthamanga kwa zida zamagetsi zamagetsi kumayendetsedwa pa 0.3-1.2m / s.Zimatsimikiziridwa pazochitika ndizochitika.M'nyengo yozizira, pamene bolodi losindikizidwa lili ndi mizere yotakata, zigawo zambiri, ndi kutentha kwakukulu kwa zigawo.Liwiro likhoza kukhala pang'onopang'ono;liwiro lakumbuyo likhoza kukhala lachangu.Ngati liwiro liri lothamanga kwambiri, nthawi yowotcherera ndi yochepa kwambiri.N'zosavuta chifukwa chodabwitsa cha kuwotcherera nyumba, kuwotcherera zabodza, kusowa kuwotcherera, mlatho, thovu mpweya, etc.;liwiro ndilochedwa kwambiri.Nthawi yowotcherera ndi yayitali komanso kutentha kumakhala kokwera kwambiri.Mosavuta kuonongeka kusindikizidwa dera matabwa ndi zigawo zikuluzikulu.

5. Njira yotumizira makina opangira mafunde

Njira yotumizira zida zowotchera mafunde nthawi zambiri imasankhidwa pakati pa madigiri 5-8.Zimatsimikiziridwa ndi dera la bolodi losindikizidwa komanso kuchuluka kwa zigawo zomwe zayikidwa.

6. Kusanthula kwa malata mu bafa yowotchera yoweyula

Kugwiritsiridwa ntchito kwa solder mu bafa ya malata ya zida zowotchera mafunde kumatchedwa pambuyo.Idzawonjezera zonyansa mu solder yowotchera yowotcherera, makamaka zonyansa zamkuwa zomwe zimakhudza mtundu wa kuwotcherera.Nthawi zambiri, zimatenga miyezi itatu kuti mufufuze zasayansi - nthawi.Ngati zodetsedwa zikupitilira zomwe zikuloledwa, njira ziyenera kuchitidwa kuti zilowe m'malo mwake.
