Indium CW-807 Wire Solder 53029-0454 | SN995 Lead-Free No-Clean ROL0 | .032" Dia | 1lb Spool
Indium CW-807 Wire Solder 53029-0454 | SN995 Lead-Free No-Clean ROL0 | .032" Dia | 1lb Spool
Indium CW-807 (part number 53029-0454) is Indium Corporation’s best-selling flux-cored wire solder in an SN995 (99.5% pure tin) lead-free formulation, .032" diameter, 1lb spool. SN995 is a silver-free, copper-free pure tin alloy — the lowest-cost lead-free wire solder option and the preferred choice for non-critical lead-free applications where SAC305’s silver content is unnecessary. CW-807 meets J-STD-004B ROL0, is halogen-free (<500ppm), and passes SIR and ECM testing. RoHS compliant.

Key Features
- SN995 pure tin — silver-free lead-free — 99.5% tin with no silver or copper additions; the lowest-cost RoHS-compliant wire solder for non-critical applications where SAC305’s silver content is unnecessary
- Halogen-free no-clean flux — ROL0 — <500ppm total halogen; meets J-STD-004B ROL0 and JEITA ET-7304; no post-solder cleaning required
- SIR & ECM tested — residue is electronically safe for virtually all applications
- RoHS compliant — pure tin SN995 contains no lead, cadmium, or other RoHS-restricted substances
- Compatible with all Indium pastes and wave fluxes — CW-807 flux chemistry is consistent across all alloy variants
Frequently Asked Questions
What is SN995 and when should I use it instead of SAC305?
SN995 is 99.5% pure tin (with 0.5% trace elements) — a silver-free, copper-free lead-free alloy. It is significantly less expensive than SAC305 because it contains no silver. Use SN995 for non-critical lead-free applications where cost is the primary driver and joint strength requirements are lower than demanding structural or thermal-cycling applications. SAC305 is preferred for high-reliability applications (automotive, aerospace, high thermal cycle count) where silver improves mechanical and fatigue properties. SN995 melts at ~232°C vs. SAC305’s ~217°C, so it requires slightly higher soldering temperatures.
Is 53029-0454 RoHS compliant?
Yes — SN995 is a lead-free alloy and is fully RoHS compliant.
Why does SN995 have a higher melting point than SAC305?
Pure tin melts at 232°C, which is higher than the SAC305 eutectic at ~217°C. The silver and copper additions in SAC305 form an alloy that melts at a lower temperature than pure tin. When switching from SAC305 to SN995, set your iron tip temperature 10–20°C higher to compensate.
Is the no-clean residue safe to leave on the board?
Yes — CW-807 passes J-STD-004B SIR and ECM tests regardless of alloy. The no-clean residue is electronically safe for virtually all applications without post-solder cleaning.
