# Solder - 1/4lb Spool (0.032") Special Blend

**Type:** Product page · **SKU:** TOL-10243 · **Brand:** [Sparkfun](https://core-electronics.com.au/brands/sparkfun-australia)
**Page:** https://core-electronics.com.au/solder-1-4lb-spool-0-032-special-blend.html ([markdown](https://core-electronics.com.au/solder-1-4lb-spool-0-032-special-blend.html.md))

We don’t want to hype this solder TOO much, but this could possibly be the best solder in the world. There, we’ve said it. This is a special blend made specifically for us and we love it. It all started as a quest to find the best solder to use in our production process and ended up being the best we’ve tried. The best part is that it’s lead free and has a water-soluble flux core.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=TOL-10243:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/TOL-10243:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)
