Mechanic Sn63/Pb37 SMD Solder Paste – 35g Syringe with Alloy Push Rod & Precision Needle for PCB Rework & Micro Soldering

Product Description:

The DHRUVPRO Sn63/Pb37 SMD Solder Paste (35g) is a high-quality, leaded soldering solution engineered for professional electronics assembly and PCB repair work. Designed for surface-mount technology (SMT), BGA reballing, and fine-pitch SMD components, this paste delivers smooth solder flow, quick wetting, and strong, reliable joints.

Packaged in a 35g syringe with an alloy push rod and precision needle, the kit allows for clean and controlled application on even the most delicate circuit boards. The alloy composition of 63% tin and 37% lead (Sn63/Pb37) provides excellent conductivity and a low melting point, making it ideal for hand soldering, reflow ovens, or hot air guns.
