Description: It's that time of year when we sell off our production scrap. These board do not work, but they make for great practice, and if you're good with the tools, you might even salvage some serious dough. These boards are a great way to encourage hot-air rework, scoring usable parts, and not having to fret if the rework goes poorly.
