Raws li qhov sib txawv ntawm cov hlau alloy, ib puag ncig cov qauv, qhov loj me, thiab cov xwm txheej ntawm cov ntawv thov, cov khoom siv hlau tuaj yeem muab faib ua tsib hom: cov khoom siv lead ua, cov hlau lead- cov pob dawb solder, cov pob micro solder, tsheb- qib solder balls, thiab tshwj xeeb - lub hom phiaj solder balls. Txhua yam ua tiav cov haujlwm tshwj xeeb thiab cov txheej txheem kev hloov pauv hauv kev ntim khoom hluav taws xob.
Lead-raws li Solder Balls (SnPb)
Hom Alloys: Sn63 / Pb37 (lub ntsiab lus melting 183 degree), Sn62 / Pb36 / Ag2 (lub ntsiab lus melting 179 degree)
Nta: Tsawg melting point, zoo wettability, dav soldering txheej txheem qhov rais, txo nqi
Lead-Pob Solder Balls (Pb-Free)
Lub ntsiab Alloys: Sn96.5Ag3.0Cu0.5 (SAC305, melting point 217-219 degree), Sn99.3/Cu0.7, Sn96/Ag4
Nta: Ib puag ncig ua raws, muaj zog txhua yam, zoo qaug zog tsis kam, tab sis siab melting point, yuav tsum nruj dua reflow soldering kub tswj.
Micro Solder Pob
Pob txoj kab uas hla: 80μm rau 300μm; ultra-micro solder npas hauv qab 50μm twb tau siv rau hauv kev ntim khoom siab heev.
Nta: Siab sphericity, micron - theem kam rau ua, tsis tshua muaj oxygen cov ntsiab lus, haum rau nplua - suab ntim.
