Lately we have been working on several concurrent projects at DesignLab, and the need for a safe way of storing and moving PCBA's around became quickly apparent. Two of my main concerns were that the assembly process includes steps that require moving boards from one place to the other, and that we would not lose track of what stage each set of boards was at (first pass, second pass, QA, firmware, etc). I shopped around online for industry-grade trays and was surprised by their cost so decided to make our own. My first trays were heavy on the materials, and the new version is much lighter.  The one to the right is the old version. The new one is to the left. Same capacity, much less material.
