Item Number: NGIN-N4200

We've tested a number of different brands, sizes, and blends of wire solder with the following criteria as guidelines:

- A low-temperature solder for minimal thermal shock to our products.
- Alloy composition for good flow and bonding to copper, brass, and nickel-silver materials, and gold, silver, or tin plated contacts and solder pads.
- Small wire solder diameter.
- Self-fluxing for ease of use.
- Packaging designed for convenient use and storage (our workbenches are cluttered enough).
