features
Cost-effective solutions, built for scale
01
Non-yellowing
Maintains mechanical and chemical stability during high-temperature assembly processes, including Pb-free reflow profiles and prolonged thermal exposure.
02
High throughput & process yield
Engineered to achieve reliable adhesion across common PCB substrates, reducing the risk of delamination during thermal cycling and operational stress.
03
High temperature resistance
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
High reliability
Enhances solder joint durability under repeated thermal cycling and mechanical loading, supporting long-term performance in demanding environments.
02
Designed for wafer-level lens or optical lens attachment
Lowers the likelihood of mechanical and thermal failure in high-temperature and high-density assemblies, improving overall system robustness.
03
Designed for wafer-level lens or optical lens attachment
Supports stable, repeatable production outcomes by reducing process variability and material-related defects across manufacturing runs.
