Solder Wire

Choosing the right solder wire is essential for successful DIY synthesizer projects.

Since 2006, leaded solder has been restricted in the EU, so you’ll need to use lead-free solder wire. A common alloy is Sn96.5/Ag3.0/Cu0.5, now widely used as the standard. It is safer for both your health and the environment.

Modern lead-free solder alloys melt and flow perfectly for all DIY projects — there’s no need for outdated, toxic lead-based solder anymore.

For synth building, we recommend Stannol Kristall 611 with a diameter of 0.7 mm. It’s a great all-purpose solder: thin enough for precise work on dense PCBs, yet strong enough for larger connections like jacks or pin headers.

Note:

Always solder with fume extraction!

Flux fumes can be harmful to your health.

When choosing solder, pay attention not only to the alloy but also to the flux core.
Good flux ensures clean, shiny joints and helps the solder flow properly. Poor-quality solder, on the other hand, can make your work unnecessarily difficult. You might end up with dull, brittle joints or sticky residues that are hard to clean.

In general, it’s worth investing in decent solder. It makes soldering smoother, helps avoid frustration, and ensures reliable connections in your module. It is crucial for stability, audio quality, and long-term durability.

Stannol - Kristall 611

available

Kristall 611 is the best solder we could currently find, so we would like to offer it to you for your DIY projects. We tested dozens of solder wires and this stood out, even on difficult surfaces.The diameter of 0,7mm makes it kind of universal. What Stannol say in their own words: The Soldering Wire Kristall 611 electronics soldering wire is based on a halogen-activated "No-Clean" flux. It has been developed for high requirements for conventional soldering and for soldering SMDs in industrial production and for repair and resoldering. The wire flux Kristall 611 is a well activated flux based on synthetic resins. it combines high activity and good flow characteristics in an outstanding way with small amounts of solid and electrically safe residues.Features:• Roll of 100g• 1Kg = 159,66€ (+ tax)• Very low flux spitting• Leaves just slightly coloured residues• Fast soldering• No-Clean residues• Chemically modified resin, reducing the health risks of using rosin based fluxes• Mild odour
