AIM SN63/PB37 OAJ 2% Water Soluble Core Wire Solder .020" Diameter

AIM SN63/Pb37 OAJ 2% Water-Soluble Core Wire Solder – .020" Diameter

High-Precision Water-Soluble Solder for Professional Electronics Assembly

The AIM SN63/Pb37 OAJ 2% Water-Soluble Core Wire Solder delivers reliable, high-quality solder joints for medium- to fine-pitch surface mount devices (SMD), printed circuit boards (PCBs), and other precision electronics applications. Its .020" diameter wire provides excellent control for consistent soldering and strong connections.

Product Overview

This solder features the traditional 63/37 tin-lead eutectic alloy (Sn63/Pb37) combined with OAJ 2% water-soluble flux core. The flux promotes superior wetting, smooth flow, and rapid soldering while leaving residues that are easily removed with water, ensuring clean, non-corrosive solder joints for high-reliability applications.

Key Features & Benefits

• .020" Diameter – Ideal for medium- and fine-pitch soldering applications.
• 63/37 Eutectic Alloy – Smooth melting and solidification for strong, reliable joints.
• OAJ 2% Water-Soluble Flux – Residues are fully removable with water, leaving a clean, corrosion-free finish.
• Excellent Wetting and Flow – Ensures consistent electrical and mechanical connections.
• Compatible with Manual and Automated Soldering – Works well in hand soldering, reflow, and robotic processes.
• Reduces Spatter – Cleaner solder joints and minimal material waste.

Applications

• Surface Mount Device (SMD) Assembly
• PCB Repair and Rework
• Medium- and High-Density Electronics Assembly
• Precision and High-Reliability Electronics Manufacturing

Cleaning Instructions
