Halogen free standard compliant printng type for LASER 8239 series

Suitable for LASER soldering

Suitable for LASER heat soldering.Achieve a good soldering quality, with avoiding satelite balls.

Reduce solder ball

●Solder ball test by LASER heating

Few solder ball occurs by rapid heating in short time
Irradiation time:0.2 sec
Parts:1005R chip

Halogen-free compliant

No intentional addition of chlorine(Cl) and bromine(Br), which genelate dioxins.Compliant with most of halogen-free standards.

Halogen-free compliant

●Compliant situation of 8239 series

Standards	Compliant situation
JPCA-ES01	Compliant
