# Lead Solder Paste - 15g Syringe

**Type:** Product page · **SKU:** AH1640 · **Brand:** [Core Electronics](https://core-electronics.com.au/brands/core-electronics-australia) · **GTIN:** 9321758158548

NC254 has been developed to offer extremely broad process windows for printing, wetting and pin probe testing. The superior wetting ability of NC254 results in bright, smooth, shiny, solder joints. NC254 offers very low post process residues, which remain crystal clear and probable even at the elevated temperatures required for today's lead free alloys. NC254 has shown to reduce or eliminate voiding under micro-BGAs. NC254 also offers high humidity tolerance and a chemistry developed for use in air reflow. Slump and humidity tolerances found in NC254 extend the solder pastes useable life in facilities where environmental control is not at its optimum. 15g Syringe Features Broad Printing Process Window Reduces Voiding under Micro-BGAs 24 Hour Stencil Life Clear Pin-Probe Testable Residue 12-14 Hour Tack Time Excellent Wetting

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=AH1640:1` (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/AH1640:1.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)
