Indium CW-807 Wire Solder 52939-0454 | SAC305 Lead-Free No-Clean ROL0 | .062" Dia | 1lb Spool | MOQ: 10

Indium CW-807 Wire Solder 52939-0454 | SAC305 Lead-Free No-Clean ROL0 | .062" Dia | 1lb Spool | MOQ: 10

Indium CW-807 (part number 52939-0454) is Indium Corporation’s best-selling flux-cored wire solder in a SAC305 (Sn96.5/Ag3/Cu0.5) lead-free formulation, in a heavy-duty .062" diameter, 1lb spool with a minimum order quantity of 10 spools. The .062" diameter is designed for high-thermal-mass applications: large through-hole joints, heavy copper ground planes, bus bar connections, power component leads, and wave soldering drag feed applications where a fine wire would require excessive feed rates. CW-807 meets J-STD-004B ROL0, is halogen-free (<500ppm), and passes SIR and ECM testing. RoHS compliant.

Note: This listing has a minimum order quantity (MOQ) of 10 spools. Contact MTE Solutions at 651-600-3838 for single-spool options or volume pricing.

Key Specifications

Key Features

• Heavy-duty .062" diameter — large diameter for high-thermal-mass joints: large through-hole pads, ground plane connections, power component leads, bus bar soldering, and wave solder drag feed applications
• SAC305 lead-free — RoHS compliant — industry-standard lead-free alloy; compatible with all SAC305-based SMT processes
• Halogen-free no-clean flux — ROL0 — <500ppm total halogen; no post-solder cleaning required
• SIR & ECM tested — residue is electronically safe for virtually all applications
• MOQ 10 — production volume — designed for production-scale consumption of heavy-gauge wire in high-throughput soldering operations

Frequently Asked Questions

When is .062" wire the right choice?
The .062" diameter delivers significantly more solder per unit length than fine wires, making it efficient for joints with high thermal mass or large pad areas. It is well-suited for large through-hole components (transformers, connectors, large electrolytics), heavy copper ground planes, power module terminals, and wave solder drag applications where feed speed and solder volume are important. For SMD and fine-pitch work, use .010"–.020" diameters instead.

Is the no-clean residue from CW-807 .062" safe to leave on the board?
Yes — CW-807 passes J-STD-004B SIR and ECM tests regardless of wire diameter. The flux chemistry is the same across all CW-807 diameters.

What temperature do I need for SAC305 with .062" wire on high-thermal-mass joints?
SAC305 melts at ~217°C but high-thermal-mass joints require significantly more heat delivery. Tip temperatures of 360–400°C are common for large through-hole and ground plane joints with SAC305. High-wattage soldering equipment (JBC T245 + C245 series, or dedicated high-power stations) is recommended for production use with .062" wire on demanding joints.

What is the MOQ and why does it apply?
The MOQ of 10 spools applies to the 52939-0454 production packaging. Contact MTE Solutions at 651-600-3838 for single-spool .062" SAC305 options or to discuss volume pricing for larger quantities.

Is 52939-0454 RoHS compliant?
Yes — SAC305 is a lead-free alloy and is RoHS compliant. CW-807 SAC305 wire is suitable for all RoHS-regulated product manufacturing.
