It was just a few days ago that we added Surface Finish (HASL, Lead-free HASL, ENIG, and Cheapest) to our board specs. Today we added one more option: Cheapest Lead-free. For many manufacturers, the cheapest finish is HASL, so if you need lead-free, choosing Cheapest would not give you the results you want. Choosing Lead-free HASL would not be the best either because some manufacturers don’t offer it, even though they have other lead-free finishes. In short, we needed a way to request the cheapest lead-free finish.
And now we have it.
