AIM SN63/PB37 OAJ 2% Water Soluble Core Wire Solder .032" Diameter

AIM SN63/Pb37 OAJ 2% Water-Soluble Core Wire Solder – .032" Diameter

High-Precision Water-Soluble Solder for Professional Electronics Assembly

The AIM SN63/Pb37 OAJ 2% Water-Soluble Core Wire Solder provides reliable, high-quality solder joints for medium- to large-pitch surface mount devices (SMD), through-hole components, and printed circuit boards (PCBs). Its .032" diameter wire ensures consistent soldering with strong mechanical and electrical connections.

Product Overview

This solder combines the classic 63/37 tin-lead eutectic alloy (Sn63/Pb37) with OAJ 2% water-soluble flux core. The flux promotes excellent wetting, smooth flow, and rapid soldering while leaving residues that are fully removable with water, ensuring clean, non-corrosive solder joints for high-reliability assemblies.

Key Features & Benefits

• .032" Diameter – Suitable for medium- to large-pitch soldering applications.
• 63/37 Eutectic Alloy – Smooth melting and solidification for reliable joints.
• OAJ 2% Water-Soluble Flux – Residues are fully water-soluble and non-corrosive, leaving a clean finish.
• Excellent Wetting and Flow – Produces consistent electrical and mechanical connections.
• Compatible with Manual and Automated Soldering – Ideal for hand soldering, reflow, and robotic processes.
• Reduces Spatter – Cleaner joints and less material waste.

Applications

• Surface Mount Device (SMD) Assembly
• Through-Hole Component Soldering
• PCB Repair and Rework
• Medium- and High-Density Electronics Assembly
