TAMURA TLF-204-NH Halogen-free solder paste
Brief introduction of characteristics of Tamura Tamura TLF-204-NH halogen-free solder paste;
- Lead-free (tin/silver/copper series) solder alloy is adopted.
- Use halogen-free flux.
- The viscosity changes little with time during continuous printing, and stable printing effect can be obtained.
- It can show good reflux effect under the condition of air reflux curve.
- It belongs to lead-free solder paste and can show good reflow effect under the condition of high temperature reflow curve.
- It belongs to non-cleaning solder paste and has good reliability.
