BQC hais txog kev tsim khoom tsis muaj hlau lead.
Kev siv ntau ntawm cov hlau lead-dawb solder, cov phooj ywg yuav twv seb nws txhais tau tias tag nrho cov PCBA boards yog cov txheej txheem tsis muaj txhuas thiab siv lead-free solder? Qhov tseeb, tsis yog txhua qhov kev ua SMT siv lead-free solder, vim tias qee zaum, xav txog tus nqi lossis lwm yam teeb meem, ntau lub tuam txhab hluav taws xob hluav taws xob yuav txuas ntxiv siv cov cuab yeej siv lead ua.
Qhov tshwm sim: ntawm lub rooj tsav xwm hauv Circuit Court, qhov saum npoo nrog cov hlau lead ua ntej zoo li ci dawb, thaum cov hlau tsis muaj hlau lead nthuav tawm lub teeb daj (vim cov hlau tsis muaj hlau lead muaj tooj liab).
Tes xav: thaum koj so lub solder nrog koj txhais tes, cov hlau lead-dawb solder yuav tawm ib lub teeb daj ntawm koj txhais tes, thaum cov hlau lead solder yuav tawm ib tug dub kab.
Muaj pes tsawg leeg: txhuas solder yog ob yam tseem ceeb ntawm tin thiab txhuas, thaum cov hlau tsis muaj hlau lead yog tsawg dua 500ppm), thiab cov hlau tsis muaj txhuas feem ntau muaj cov tin, nyiaj lossis tooj liab hlau.
Kev siv: txhuas solder yog siv rau vuam cov khoom siv lead ua. Cov cuab yeej thiab cov khoom siv yog cov hlau lead. Lead free solder yog siv rau cov hlau lead-free soldering ntawm cov khoom xa tawm mus rau Tebchaws Europe, America thiab lwm lub tebchaws. Nws cov cuab yeej thiab cov khoom siv yuav tsum tsis muaj hlau lead.
