Iiparamitha zenkqubo eziphambili zeizixhobo zokuphinda zifakwe kwi-solderingkukudluliselwa kobushushu, ulawulo lwesantya setsheyini kunye nesantya somoya kunye nolawulo lomthamo womoya.
1. Ukulawulwa kokudluliselwa kobushushu ngaphakathii-oven yokuthambisa.
Okwangoku, iimveliso ezininzi zisebenzisa itekhnoloji ye-lead-free, ngoko keumatshini wokuphinda uphinde udibaniseesetyenziswayo ngoku ubukhulu becala ngumoya oshushui-reflow soldering.Kwinkqubo ye-solder-free-solder, kuyimfuneko ukubeka ingqalelo kwimpembelelo yokutshintshwa kobushushu kunye nokusebenza kakuhle kokutshintsha kobushushu.Ngokukodwa kumacandelo anamandla amakhulu okushisa, ukuba ukuhanjiswa kobushushu okwaneleyo kunye notshintshiselwano alunakufumaneka, izinga lokushisa liya kuba liphantsi kakhulu kunezixhobo ezinomthamo omncinci wokushisa, okubangelwa ukuhluka kweqondo lokushisa elisecaleni..Imowudi yokuhamba komoya yomzimba we-oven yokuphinda ichaphazele ngokuthe ngqo isantya sokutshintsha ubushushu.Iindlela ezimbini zokuhambisa umoya oshushu zokuphinda zifakwe kwi-solder ezi: micro-circulation indlela yokuhambisa umoya oshushu, kwaye enye ibizwa ngokuba yindlela encinci yokuhambisa umoya oshushu.
2. Ukulawulwa kwesantya setsheyinii-reflow soldering.
Ukulawulwa kwesantya se-chain ye-reflow soldering izixhobo kuya kuchaphazela ukuhluka kweqondo lokushisa elisecaleni kwebhodi yesekethe.Ngokubanzi, ukunciphisa isantya setsheyini kuya kunika isixhobo esinomthamo omkhulu wobushushu ixesha elingakumbi lokufudumeza, ngaloo ndlela sinciphisa umahluko wobushushu osecaleni.Kodwa emva kwayo yonke loo nto, ukusetwa kwesithando somlilo kuxhomekeke kwiimfuno ze-solder paste, ngoko ke akukho ngqiqweni ukunciphisa isantya sekhonkco ngaphandle komda kwimveliso yangempela.
3. Ukulawulwa kwesantya somoya kunye nomthamo womoya we-reflow soldering izixhobo.
Gcina ezinye iimeko kwireflow oveningatshintshi kwaye inciphisa kuphela isantya se-fan kwi-oven reflow nge-30%, iqondo lokushisa kwibhodi yesiphaluka liya kuhla malunga ne-10 degrees.Kuyabonakala ukuba ukulawulwa kwesantya somoya kunye nomthamo womoya kubalulekile ekulawuleni ubushushu bomlilo.
Ukuze uqonde ulawulo lwesantya somoya kunye nomthamo womoya, amanqaku amabini kufuneka athathelwe ingqalelo:
a.Isantya sefeni kufuneka silawulwe ngokuguqulelwa rhoqo ukunciphisa impembelelo yokuguquguquka kwamandla ombane kuyo;
b.Ukunciphisa umthamo womoya wokukhutshwa kwezixhobo, kuba umthwalo ophakathi womoya wokukhupha udla ngokungazinzi, ochaphazela ngokulula ukuhamba komoya oshushu kwisithando somlilo.
