Microstructure of lead-free solder bumps using laser reflow soldering

Lead-Free Soldering for Space Applications Lead-Free Solder Body of Knowledge

Lead-free Solder Assembly

Until non-lead solder conversion is mature, the evaluation of materials and components is likely to identify trade-offs. The performance of the no-clean andwater-soluble solder pastes that were tested varied widely. Ultimately each company will need to determine which attributes are most important for their product line. Also components needed for a product may not be currently available as lea...

The Impact of Reflowing A Pbfree Solder Alloy Using A Tin/Lead Solder Alloy Reflow Profile On Solder Joint Integrity

The electronics industry is undergoing a materials evolution due to the pending Restriction of Hazardous Substances (RoHS) European Directive. Printed wiring board laminate suppliers, component fabricators, and printed wiring assembly operations are engaged in a multitude of investigations to determine what leadfree (Pbfree) material choices best fit their needs. The size and complexity of Pbfr...

Nitrogen in IR Reflow Soldering

Solder doped polycaprolactone scaffold enables reproducible laser tissue soldering.

BACKGROUND AND OBJECTIVES In this in vitro feasibility study we analyzed tissue fusion using bovine serum albumin (BSA) and Indocyanine green (ICG) doped polycaprolactone (PCL) scaffolds in combination with a diode laser as energy source while focusing on the influence of irradiation power and albumin concentration on the resulting tensile strength and induced tissue damage. MATERIALS AND MET...
