Kodi kutentha kwa soldering komwe mukutsata ndi kotani?

Nthawi zambiri, chinthu chachikulu chomwe chimakhudza nthawi ya moyo wasoldering chitsulonsonga ndi kutentha kwa soldering.

Asanakhazikitsidwe mwalamulo malamulo a RoHS (zoletsa pa zinthu zoopsa) pa Julayi 1, 2006, lead mu waya wa solder amaloledwa.Pambuyo pake, kugwiritsa ntchito lead (ndi zinthu zofananira) ndikoletsedwa kupatula zida ndi njira zotsatirazi: zida zamankhwala, zida zowunikira ndi kuzindikira, zida zoyezera ndi zida makamaka m'magawo ankhondo ndi zamlengalenga kuphatikiza masensa agalimoto (njira zowongolera magalimoto ndi zinthu za airbag. ), makampani oyendetsa njanji, etc.

Waya wotsogola wotsogola kwambiri amakhala ndi malo osungunuka pafupifupi madigiri 180.Malo osungunuka a waya wamba wopanda lead wopanda aloyi ndi pafupifupi madigiri 220.Kusiyana kwa kutentha kwa madigiri 40 kumatanthauza kuti kuti amalize zokhutiritsasolderolowa mu nthawi yomweyo, tiyenera kuwonjezera kutentha kwa siteshoni soldering (ngati soldering nthawi kuchuluka, n'zosavuta kuwononga zigawo zikuluzikulu ndi PCB bolodi).Kuwonjezeka kwa kutentha kudzachepetsa moyo wautumiki wa nsonga yachitsulo cha soldering ndikuwonjezera zochitika za okosijeni.

Chithunzi chotsatirachi chikuwonetsa zotsatira za kuwonjezeka kwa kutentha pa moyo wautumiki wa nsonga yachitsulo cha soldering.Kutenga madigiri 350 monga mtengo wofotokozera, pamene kutentha kumawonjezeka kuchokera ku madigiri 50 kufika ku madigiri 400, moyo wautumiki wa nsonga yachitsulo yosungunuka udzachepetsedwa ndi theka.Kuchulukitsa kutentha kwautumiki wa nsonga yachitsulo cha soldering kumatanthauza kuti moyo wautumiki wa nsonga yachitsulo chachitsulo umachepetsedwa.

Nthawi zambiri, kutentha kwa soldering ya alloy wopanda lead aloyi tikulimbikitsidwa kukhala 350 ℃.Komabe, mwachitsanzo, chifukwa kukula kwa 01005 phiri chipangizo ndi kochepa kwambiri, timalimbikitsa 300-degree soldering ndondomeko.

Kufunika kolondola

Muyenera kuyang'ana kutentha kwa siteshoni ya soldering nthawi zonse, zomwe sizingangowonjezera moyo wautumiki wa nsonga yachitsulo, komanso kupewa kutentha kwambiri kapena kutentha kochepa pamene mukugulitsa zinthu.

Zonsezi zingayambitse mavuto panthawi ya soldering:

· Kutentha kwakukulu: ambiri ogwira ntchito ophunzitsidwa adzaganiza kuti n'koyenera kuwonjezera kutentha kwa soldering kuti athetse vutoli pamene apeza kuti solder sangathe kusungunuka mwamsanga.Komabe, kuonjezera kutentha kumapangitsa kuti kutentha kwa malo otentha kukhale kokwera kwambiri, zomwe zingayambitse kugwedezeka kwa pedi, kutentha kwambiri kwa solder, kuwononga gawo lapansi ndi ma solder ndi khalidwe loipa kwambiri.Panthawi imodzimodziyo, idzawonjezera makutidwe ndi okosijeni wa nsonga yachitsulo cha soldering ndikuwononga nsonga yachitsulo cha soldering.

• Kutentha kocheperako kungapangitse kuti mukhale nthawi yayitali kwambiri pakuwotchera komanso kusamutsa kutentha kwambiri.Izi zidzakhudza kupanga mphamvu ndi khalidwe la ozizira solder olowa.

Choncho, molondola kutentha kuyeza n'kofunika kupeza kukonzekera soldering kutentha.
