The die attach process is a key step in power packages manufacturing to ensure product reliability. Heraeus Electronics solder wires ensure excellent thermal performance of the solder connection, improves customer’s yield and product reliability.

Reliability demands of electronic components are rising: High power applications and rising customer expectations put pressure on the solder interconnect thermal performance. Thermal and mechanical fatigue defects in electronic components are caused primarily from successive on/off cycling. To maximize reliability, engineers must identify the optimal combination of material performance and properties.                                                                                                                                  

A perfect solder connection is crucial for the thermal performance. Ideal wetting as well as low void rates help to create consistent connections at highest reliability. Heraeus solid core soft solder wires are flux free and especially optimized for high performance components and die attach applications. They are manufactured by a sophisticated extrusion process that leads to extremely tight diameter tolerances and is free of organic contamination and oxides. Heraeus Electronics solder wires guarantee a consistent bondline thickness (BLT) and a very low tilt rate.                                                

We offer lead-containing as well as lead-free solder wires. Some alloys are available in wetting enhancement options to further improve slump and wetting.
