Good finish even with rapid heating from lasers; compatible with printing methods.
Compatible with laser methods The 'EVASOL 8239 series' is compatible with light heating methods such as lasers. It suppresses solder balls, which can be problematic during rapid heating, achieving excellent finishing quality. Compatible with printing methods Until now, it has been difficult for solder pastes for lasers to accommodate printing methods. It is now possible to transfer using existing equipment. Compliant with halogen-free standards It does not contain Cl and Br, which are causes of dioxin generation. It complies with most halogen-free standards. 【Features】 ■ Prevents solder balls ■ Stable viscosity characteristics ■ Compliant with halogen-free standards *For more details, please refer to the PDF document or feel free to contact us.
