goobay Lead-free silver solder wire Ag0.3 Cu0.7, 1 mm, 2.5 % no-clean flux, 250 g

The goobay 40845 solder listing, bullet by bullet

Five bullets: a 250 g reel of 1 mm lead-free wire with 0.3 % silver, 0.7 % copper, 96.5 % tin and 2.5 % flux, melting at 217 °C and free of halogens; a no-clean flux that leaves joints needing no cleaning; firm joints with little smoke; silver for better electrical and thermal conductivity; and uses from cables to smartphones and boards.

goobay’s shares add up with the flux

96.5 + 0.3 + 0.7 + 2.5 = 100. The first bullet counts the flux into the percentages. The metal alone is then roughly 99 % tin, which matches the same silver-copper alloy the Ka wah core reel on this site names.

At 250 g, this reel lasts. The listing mentions low smoke; ventilation and fume handling are not addressed.

Availability

At the last look-up, the German, French, Italian and Spanish Amazon stores were asking 32 € to 45 €.

It is sold in the British Amazon store as well, in its own currency, which the euro figures above leave out on purpose.

The American Amazon store returned no entry, so the buy button there opens a search rather than a missing page.

Every figure here is Keepa’s reading on the date this page was last updated. Stock and prices can change at any time.
