PD-35免清洗耐高温树脂芯无铅焊锡丝

pd-35免清洗耐高温树脂芯无铅焊锡丝的特点：焊剂在较高温度焊接时不失活性，焊接湿润能力强，焊接碳化物少，焊点不易桥连、拉尖。酸值kohmg/g≤200；卤素含量≤0.3%；焊剂flux1.5-2.5wt%，适合作300-400°c 的高温焊接。
features:during the high temperature soldering,pd-35will not lose the zctivate,with the properties of strong witting,minimum carbide bright and nice soldering spots without bridge and lugging tine.acid:kohmg/g≤200，halide percentage≤0.3%，flux1.5-2.5wt%，it is suitable for 300-400°c high temperature soldering.
