Indium CW-807 Wire Solder 52906-0454 | Leaded 63/37 No-Clean ROL0 | .020" Dia | 1lb Spool | MOQ: 10
Indium CW-807 Wire Solder 52906-0454 | Leaded 63/37 No-Clean ROL0 | .020" Dia | 1lb Spool | MOQ: 10
Indium CW-807 (part number 52906-0454) is Indium Corporation’s best-selling flux-cored wire solder — a leaded Sn63/Pb37 (63/37) eutectic formulation in .020" diameter, sold in 1lb spools with a minimum order quantity of 10 spools. CW-807 is compatible with all Indium no-clean solder pastes, wave fluxes, and all common soft solder alloys. It meets J-STD-004B ROL0 classification, contains less than 500ppm total halogen (halogen-free per J-STD-004B and JEITA ET-7304), and passes the stringent SIR and ECM requirements of J-STD-004B — making the no-clean residue electronically safe for virtually all applications without post-solder cleaning.
Note: This listing has a minimum order quantity (MOQ) of 10 spools. For single-spool purchase, see 52905-0454 (.032" dia, 1lb) or contact MTE Solutions at 651-600-3838.

Key Features
- Indium’s best-selling wire solder — .020" leaded — the .020" diameter is a popular all-around choice for hand soldering SMD and through-hole components; finer than .032" for better control on smaller joints
- 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 including high-impedance and RF circuits
- 63/37 eutectic alloy — melts at a single point (183°C) with no plastic range; crisp, bright joint formation
- MOQ 10 — volume pricing — this listing is for production and high-volume users; contact MTE Solutions for volume pricing on larger quantities
Frequently Asked Questions
Why is .020" a popular diameter for hand soldering?
The .020" diameter is a versatile middle ground — fine enough for good control on 0603 SMD components and QFP leads without depositing excess solder, while still substantial enough for efficient through-hole work. Many technicians prefer .020" as a single go-to diameter for mixed hand soldering tasks. The .032" is better for large through-hole and high-thermal-mass joints; .015" and finer are for ultra-precision SMD work.
What is the MOQ and why does this listing require 10 spools?
The MOQ of 10 spools applies to the 52906-0454 configuration. Volume packaging allows Indium Corporation to offer better per-spool pricing for production users. If you need fewer than 10 spools, contact MTE Solutions at 651-600-3838 — we can advise on alternative part numbers without MOQ requirements.
Is the no-clean residue from CW-807 safe to leave on the board?
Yes — CW-807 passes J-STD-004B SIR and ECM tests, confirming the residue is electronically safe for virtually all applications without cleaning. The residue is light-colored for easy post-solder inspection.
Is 52906-0454 RoHS compliant?
No — the 52906-0454 contains a leaded Sn63/Pb37 alloy and is not RoHS compliant. It is intended for leaded processes, RoHS-exempt applications, or repair of existing leaded assemblies.
What other CW-807 63/37 leaded options are available?
CW-807 63/37 leaded wire is available in .015", .020", and .032" diameters in 1lb and 1/4lb spools, with and without MOQ requirements. Contact MTE Solutions at 651-600-3838 to find the right configuration for your process.
