NC-560-LF 10CC一支 松香基础材料故颜色偏黄,ROL0,低活性
无铅免清洗无卤素,短时间耐受300度高温
NC-560-LF is a lead-free, no-clean, halide-free solder paste that delivers improved solderability with all Pb-Free metallization, including ENIG (Gold), OSP, HASL and immersion silver boards. NC-560-LF is RoHS-compliant and increases production yields with its unparalleled lot-to-lot and stencil printing consistency, and offers superior print performance characteristics, including excellent wetting, strong activity, ideal viscosity, long stencil life, thermal stability up to 300°C, and minimal residue. NC-560-LF is also low beading, low voiding, and anti-tombstoning to reduce scrap and rework.
LF-4300-TF 10CC一支 树脂基础材料故颜色白色透明,REL0,低活性
无铅免清洗可水洗无卤素,亦可用于有铅焊锡丝
The LF-4300-TF is a medium viscosity water-washable, no-clean flux designed for tin-lead and lead-free alloys. LF-4300-TF is ideal for BGA, PGA and CSP sphere or pin attachment. Can be dot dispensed or screen printed. LF-4300-TF can be used with either tin-lead or lead-free alloys.
淘宝假货太多,按照筒友思路直接联系总代理,email购物
价格稍微贵一点,但保证正品
折腾无铅焊接,传统有铅助焊剂,因高温挥发太快,无法发挥全部效力
NC-560-LF是流行的NC-559的无铅版本,RMA-223-LF为流行的RMA-223的无铅版本
RMA-223未写免洗,故一定要清洗,不然其SIR达不到要求
这两天在和chemtronics联系,打算购入CW8400
可能焊锡丝也要联系一家国外厂商,继续email购物之旅
虽然焊接量很小,DIY水平较低,花费比较大,但可以试用到国外先进产品,且保证正品
查查各品牌产品的PDF,看看其网站,联系一下留下的email,也有不少乐趣在其中
