    產品描述:
    對環境污染的控制已成為經濟發展中的首要義題,錫鉛焊料是一種高度有毒的金屬合金,它作為組裝輔料被廣泛用于現代電子組裝工業。隨著歐美RoHS指令的實施,電子產品制造商已經趨向于焊料的無鉛化。
    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.
     
    由博億萊公司研發的BYL-505系列焊錫膏為客戶提供優良的可焊性與印刷型。BYL-505系列焊錫膏解決了無鉛焊料在應用中出現的各種問題,如:儲存于 運輸穩定性,潤濕性差以及由高溫焊料導致的錫膏不耐熱性。
    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.
     
    產品特性:
    該產品是殘留物無色透明,活性適中,BGA空洞率低,手動印刷不費力,主要用于中高端產品,如DVD,機頂盒等
