Overview
A no-clean flux in the wire core is the working part of this Kester lead-free solder, supplied as thin wire. The listing names the series and diameter and little else.
Lead-free and no-clean describe the wire in plain terms, enough to place it in electronics work that avoids both lead and washing. The limitation is that the description restates the title, so composition and temperature data are absent.
Who it's for
Technicians who reorder this Kester series by part code can match the listing to their records. Buyers choosing a solder for the first time should confirm the alloy and temperature range with the maker.
Pros and cons
- One pound quantity
- Alloy composition not listed
- Description only repeats the title
- No melting range given
Performance notes
The flux in the wire core cleans the joint as the alloy melts and leaves residue that the title describes as no-clean. The listing offers no wetting, residue or temperature data.
