MC V4B48 Lead-Free Solder Paste (35g)

The MC V4B48 Lead-Free Solder Paste (35g) is a reliable solution for SMD soldering, PCB repairs, and fine-pitch electronics assembly. Formulated using a lead-free Sn42/Bi58 alloy, this solder paste ensures a cleaner, safer working environment without compromising on performance.

Thanks to its low melting point (~138°C) and smooth viscosity, the MC V4B48 is easy to apply with stencils, syringes, or manually. Whether you’re assembling Arduino-based circuits, repairing Raspberry Pi boards, or working on IoT modules, this solder paste flows evenly, adheres strongly, and leaves minimal residue—making post-soldering cleanup quick and easy.

Additionally, its no-clean formulation reduces the need for harsh solvents or additional cleaning steps. The paste performs reliably in both reflow oven and hot air soldering processes, especially when used with tools from our Tools and Accessories or in conjunction with modules from the Arduino and Accessories section.

Its compact 35g container makes it ideal for lab technicians, electronics engineers, or hobbyists who need precise application without waste. Whether you’re into DIY kits or professional SMD assembly, this paste delivers every time.
