RELIFE Solder Paste RL-403S 183°C
RELIFE Rl-403s Low-Temperature Syringe PPD Paste 183°C. The paste is fine and the particles are fine only 20~38 microns. Excellent wettability, the surface is still wet after 36 hours of opening and does not affect the welding. Strong welding ability, high resistance, strong activity, bright and full tin.
The RELIFE RL-403S is a professional-grade solder paste formulated for electronics manufacturing and rework. Based on the classic Sn63/Pb37 eutectic alloy, it provides reliable, predictable melting characteristics for strong solder joints. Its “no-clean” flux chemistry leaves minimal, non-conductive, and non-corrosive residue, often eliminating the need for a post-soldering cleaning step in many applications. The fine particle size (Type 4) makes it particularly suitable for printing or dispensing onto circuit boards with fine-pitch components and high-density layouts. It is supplied in a convenient 10CC syringe for manual application or compatibility with dispensing equipment, requiring refrigerated storage to maintain optimal performance.
