## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA3217:1` (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/ADA3217:1.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.

## Description

Does your prototyping project require soldering? Are you looking for something other than your usual run-o'-the-mill solder wire? Look no further! This high quality, low cost, adorably packaged **Lead-Free Prototyping Solder Paste** from IC Breakout will provide strong, flux-aided conductive bonds for your board.

This paste is now reformulated to melt at very low temperatures - only 140 **°**C!

Since it’s premixed, all you need to do is screw on the self-piercing cap, squeeze the paste onto your solder pads, and heat it up using a soldering iron, oven, or any other thermal source to reach the reflow temperature of 140 **°**C (284 **°**F). Once liquidus, remove your heat source and let it cool.

The lead free metal content is a mix of Bismuth, Tin and Silver. The mix is a eutectic solder, meaning that it’s either going to be a solid or liquid during re-flow; not something in between.

**Features:**

- Lead free
- No clean-up
- Clear residue
- Premixed, ready to use
- Low temperature use

**Note: Refrigerate after opening**

**Specifications:**

- Bi57 42Sn Ag1
- ~10 grams
- Liquidus at 140 **°**C (284 **°**F)
