138/183 Degree Lead-Free Low Temperature Solder Paste

138/183 Degree Lead-Free Low Temperature Solder Paste is formulated to enable reliable soldering at reduced peak temperatures while maintaining solder joint integrity for delicate assemblies and temperature-sensitive components. By flowing and wetting at lower reflow temperatures, this paste helps minimize thermal stress on substrates, connectors, and electronic parts that cannot tolerate high-temperature profiles.This solder paste is lead-free and intended for applications where lower process temperatures are required, such as mixed-technology boards, polymer substrates, or assemblies with heat-sensitive components. The reduced reflow range can shorten thermal exposure and may improve throughput in processes where lower soak and peak temperatures are beneficial.Key features include consistent printability, predictable slump control, and reliable wetting behavior across the specified low-temperature profile. The paste is formulated to provide stable solder paste rheology for stencil printing, allowing accurate deposit volumes and fine-pitch capability when used with appropriate process parameters. It also offers good tack and handling strength after printing to support component placement during manual or automated pick-and-place operations.For best results, follow recommended stencil design, printing parameters, and reflow profile optimization tailored to your assembly and equipment. Validate the paste in your manufacturing environment to determine the ideal ramp rates, soak times, and peak temperatures for your specific components and substrates. Proper storage and handling according to supplier guidance will help maintain paste performance over time.
