Halogen free less spattering type 8850 series

Good wettability, applicable to low-Ag solder

The special activater enables to use low-Ag alloy.Achieves both of halogen-free and cost reduction.

Good wettability for both of 3％ Ag and low Ag

●High temperature preheating test

Low Ag alloy has euivalent wettability to 3Ag
Condition:Atmospheric
Component:QFP
0.5mm pitch

Reduce the chip side balls

Easily applicable to low Ag for the improved heat resistance of the flux.It may help to reduce the cost.

Reduce the chip side balls

●Chip side ball test after reflow(3216 chip)

Reduce the chip side ball, ensure the good SMT quality

Reduce flux spattering

Selecting proper activator achieved less flux spattering during reflow soldering

Less flux spattering

●Spattering test with reflow
