Cleaning
We clean boards really well! You shouldn’t find any traces of flux residue at all. If you do somehow come across any flux left over on your board, unless your design is highly specialized, it is considered very safe to leave on the board. The flux we use is considered to be non-conductive and non-corrosive.
Lead free since ‘23
We ONLY use lead-free solder. This applies to every assembly step, for every single job we handle. In fact, to make sure that there’s absolutely zero chance of a “mix up”, we don’t even carry leaded solder on our premises.
It’s safer for our operators, better for the Earth, and despite the claims, really isn’t much harder to work with.
