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
Excellent mechanical shock performance
Engineered to achieve reliable adhesion across common PCB substrates, reducing the risk of delamination during thermal cycling and operational stress.
03
High process yield
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
Can flow into a 10μ gap at room temperature without preheating
Enhances solder joint durability under repeated thermal cycling and mechanical loading, supporting long-term performance in demanding environments.
02
Minimizes induced stresses
Lowers the likelihood of mechanical and thermal failure in high-temperature and high-density assemblies, improving overall system robustness.
03
Minimizes induced stresses
Supports stable, repeatable production outcomes by reducing process variability and material-related defects across manufacturing runs.
