Indium CW-807 Wire Solder 53300-0454 | Leaded 63/37 No-Clean ROL0 | .020" Dia | 1lb Spool | Box of 10
Indium CW-807 Wire Solder 53300-0454 | Leaded 63/37 No-Clean ROL0 | .020" Dia | 1lb Spool | Box of 10
Indium CW-807 (part number 53300-0454) is Indium Corporation’s best-selling flux-cored wire solder — a leaded Sn63/Pb37 (63/37) eutectic formulation in .020" diameter, packaged as a box of 10 x 1lb 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 is sold as a box of 10 x 1lb spools (10 lbs total). For single-spool purchase of 63/37 leaded wire, contact MTE Solutions at 651-600-3838.

Key Features
- Box of 10 — production volume packaging — cost-effective for production lines and high-volume hand soldering operations; consistent lot traceability across the full box
- .020" leaded 63/37 — versatile diameter for SMD and through-hole hand soldering; eutectic alloy melts at a single point (183°C) for crisp joint formation
- 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
- Compatible with all Indium pastes and wave fluxes — ideal for mixed SMT/hand-solder processes using Indium paste
Frequently Asked Questions
What is the total weight of a box of 53300-0454?
Each box contains 10 x 1lb spools for a total of 10 lbs of wire solder. This is the standard production box configuration for CW-807 leaded .020" wire.
Is the no-clean residue safe to leave on the board?
Yes — CW-807 passes J-STD-004B SIR and ECM tests, confirming the residue is electronically safe without cleaning. The light-colored residue is easy to inspect post-solder.
Is 53300-0454 RoHS compliant?
No — the 53300-0454 contains a leaded Sn63/Pb37 alloy and is not RoHS compliant. For RoHS-compliant lead-free options, see Indium CW-807 SAC305 or SN995 variants.
What makes CW-807 compatible across mixed soldering processes?
CW-807 shares flux chemistry with all Indium no-clean solder pastes and wave fluxes. This means shops using Indium SMT paste can use CW-807 wire for hand soldering and rework without introducing a different flux chemistry, simplifying process control and no-clean residue management.
Can I order fewer than a full box?
This listing is for a full box of 10 spools. Contact MTE Solutions at 651-600-3838 for single-spool options or to discuss order quantities that fit your production needs.
