Solder pastes

Best-in-class thermal performance, flexibility, reflow and reliability

AVAILABLE DIRECTLY AT CAPLINQ.COM

Solder Pastes

We offer a portfolio of solder die attach pastes that deliver the process flexibility, thermal performance, high reliability and ease of use that modern power device manufacturers demand. They provide the thermal management necessary for today’s smaller outline, higher functioning semiconductor power devices, while also delivering the processability and versatility associated with solder paste materials. Optimized rheology allows for printing or dispensing depending on process preferences and advanced flux technology is compatible with a wide range of reflow profiles to enable alloy adaptation when required. These products offer robust options for application-specific thermal requirements and overcome many of the issues historically associated with alternative products.

Solder is frequently used as an alternative to conventional die attach paste when the application calls for high thermal and electrical performance. As leadframe-based devices such as SOICs, TSOPs and TSSOPs are often exposed to high temperatures during subsequent board assembly processing, high melt point alloys are important. Optimized rheology allows for printing or dispensing depending on process preferences and advanced flux technology is compatible with a wide range of reflow profiles to enable alloy adaptation when required.

Proper solder alloy formulation is vital for laminate-based packages, as the melting point must be tightly controlled to maintain the integrity of the organic substrate. Awardwinning halogen-free, lead-free solder paste materials offer low-voiding performance and can be processed at lower reflow temperatures to align with the requirements of wirebond laminate package processing.
