TAMURA TLF-204-MDS Lead-free solder paste
Brief introduction of Tamura Tamura TLF-204-MDS lead-free solder paste;
- Lead-free (tin/silver/copper series) solder alloy
- The viscosity changes little with time during continuous printing, and stable printing effect can be obtained.
- Can effectively reduce cavities.
- Can effectively reduce the generation of solder balls between components.
- Can effectively improve the preheating fluidity.
- It belongs to lead-free solder paste and can show good reflow effect under the condition of high temperature reflow curve.
- It also has good tin-plating performance for pads with a spacing of 0.4mm such as BGA.
