# Solder Paste - 50g (Lead Free)

**Type:** Product page · **SKU:** TOL-12878 · **Brand:** [Sparkfun](https://core-electronics.com.au/brands/sparkfun-australia)
**Page:** https://core-electronics.com.au/solder-paste-50g-lead-free.html ([markdown](https://core-electronics.com.au/solder-paste-50g-lead-free.html.md))

This is 50g of high quality, Lead-Free Solder Paste, the perfect amount to keep around for prototyping and hobby projects that require a bit of SMD soldering. Solder Paste Stenciling is the easiest and quickest way to solder some of the trickier SMD components. Here at SparkFun, we use solder paste stenciling on pretty much all of our boards. It saves us a lot of time. But stenciling takes more than just a stencil and a dream… you’re going to need some paste.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=TOL-12878:1` (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-12878:1.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)
