RL 404S 138°C Lead Free Low Temperature Solder Paste Relife

RL 404S 138°C Lead Free Low Temperature Solder Paste Relife 

RL-404S 138 °C Lead-Free Low-Temperature Solder Paste (RELIFE) is a specialized solder paste designed for soldering sensitive electronic components that cannot withstand the high heat typical of standard soldering processes. Unlike regular solder paste that melts at higher temperatures, this low-temperature paste melts at approximately 138 °C, reducing the risk of thermal damage to delicate parts like LCDs, LEDs, sensors, and other heat-sensitive devices. It is lead-free, making it suitable for applications that require RoHS compliance or reduced environmental impact. The paste combines fine solder alloy particles with flux in a paste form, making it easy to apply before soldering.
