Indium CW-807 Wire Solder 53030-0454 | SN995 Lead-Free No-Clean ROL0 | .020" Dia | 1lb Spool
Indium CW-807 Wire Solder 53030-0454 | SN995 Lead-Free No-Clean ROL0 | .020" Dia | 1lb Spool
Indium CW-807 (part number 53030-0454) is Indium Corporation’s best-selling flux-cored wire solder in an SN995 (99.5% pure tin) lead-free formulation, .020" diameter, 1lb spool. SN995 is a silver-free, copper-free pure tin alloy — the lowest-cost RoHS-compliant wire solder for non-critical lead-free applications where SAC305’s silver content is unnecessary. The .020" diameter is the most versatile general-purpose hand soldering diameter. CW-807 meets J-STD-004B ROL0, is halogen-free (<500ppm), and passes SIR and ECM testing. RoHS compliant.

Frequently Asked Questions
What is the difference between 53030-0454 (.020") and 53029-0454 (.032") SN995?
Both are SN995 CW-807 1lb spools but differ in diameter. The .020" (53030-0454) is more versatile for mixed SMD and through-hole hand soldering, giving better control on smaller joints. The .032" (53029-0454) is suited for larger through-hole joints and higher-thermal-mass applications where more solder volume per unit length is needed. Choose .020" as a general-purpose SN995 option; .032" for heavy-gauge work.
When should I use SN995 instead of SAC305?
Use SN995 when cost is the primary driver and your application does not require the mechanical strength or thermal fatigue resistance that SAC305’s silver content provides. SN995 is well-suited for non-structural joints, light consumer electronics, and applications with limited thermal cycling requirements. For automotive, aerospace, or high-reliability applications, SAC305 is the preferred alloy.
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 or diameter. The no-clean residue is electronically safe for virtually all applications.
What temperature should I use for SN995 hand soldering?
SN995 melts at ~232°C — about 15°C higher than SAC305. Typical hand soldering tip temperatures are 340–380°C depending on joint thermal mass. Increase tip temperature by 10–20°C compared to SAC305 settings.
Is 53030-0454 RoHS compliant?
Yes — SN995 is a lead-free alloy and is fully RoHS compliant.
