High reliability type for automotive 1500 series

Prevent crack of residue

Elasticity of flux residue of applying special resin prevents crack of residue after soldering and helps to improve surface insulation resistance greatly

Prevent residue crack

●Thermal shock test(QFP shoot in transmitted light)

【Conditions】
-40℃ to 80℃ 30min 168 Cycles,
0.5mm pitch QFP

Good wettability

Select suitable activators for synthetic resin and the wettability is almost same as conventional solder paste

Good wettability

●Test by reflow soldering
