features

Cost-effective solutions, built for scale

01
Outstanding thermal cycling performance
Maintains mechanical and chemical stability during high-temperature assembly processes, including Pb-free reflow profiles and prolonged thermal exposure.
02
100% compatible with Flux Residue
Engineered to achieve reliable adhesion across common PCB substrates, reducing the risk of delamination during thermal cycling and operational stress.
03
5x260°C Reflow
Formulated to minimise mechanical stress at the solder joint interface, helping to mitigate fatigue and micro-cracking over the product’s operational lifetime.
benefits

Designed for Long-Term Reliability

01
Environmentally friendly
Enhances solder joint durability under repeated thermal cycling and mechanical loading, supporting long-term performance in demanding environments.
02
Low cost ownership
Lowers the likelihood of mechanical and thermal failure in high-temperature and high-density assemblies, improving overall system robustness.
03
Low cost ownership
Supports stable, repeatable production outcomes by reducing process variability and material-related defects across manufacturing runs.
