产品描述:
对环境污染的控制已成为经济发展中的首要义题,锡铅焊料是一种高度有毒的金属合金,它作为组装辅料被广泛用于现代电子组装工业。随着欧美RoHS指令的实施,电子产品制造商已经趋向于焊料的无铅化。
The control of environmental pollution has been considered as top priorities in economy development.Tin-lead solder is a highly poisomous metal alloy to used widely in modern modern assemble industry as assemable material .As EU RoHS directive adaptep and the electronic manufactuer has move to ward to lead-free process.
由博亿莱公司研发的BYL-505系列焊锡膏为客户提供优良的可焊性与印刷型。BYL-505系列焊锡膏解决了无铅焊料在应用中出现的各种问题,如:储存于 运输稳定性,润湿性差以及由高温焊料导致的锡膏不耐热性。
BYL220 series solder paste was developed by TongFang company,which provide excellent and printbility to meet customer’s needs.The BYL220 series solves various prob lems as the implementation of lead-free solder.suceh asstorage stability,delivery stality,poorsolder wettability,and poor solder paste heat resistance caused by the high temperature solder.
产品特性:
该产品是残留物无色透明,活性适中,BGA空洞率低,手动印刷不费力,主要用于中高端产品,如DVD,机顶盒等
