Rev. 3.0 will incorporate user input. What should be on the next layout?
The current SMTA Miniaturization Test Vehicle was released in 2018 and is projected to have an effective lifespan of three to five years. Its design has served the SMT community well – and will continue to do so with an updated layout, bill of materials (BoM) and associated programming and analysis files slated for release in late 2022.
The board is used for standard tests, such as solder paste selection, wipe frequency and pad or aperture design, which will remain the same in the new revision, albeit with some components removed and others added. FIGURES 1 and 2 show the top and bottom sides of the board with the footprints that will be removed outlined in orange, and ones that may be removed outlined in blue:
With all the newly available real estate, what will we add to the board? That’s up to the SMTA community. What do users want on the next layout? Here are some ideas we’ve received so far:
Should the 0402s stay or go? What about the wet bridge test patterns? I’m asking for user input through the month of May, and layout efforts will begin this summer. SMTA Rev 3.0 is planned to make its debut Oct. 31 - Nov. 3 at SMTA International 2022 in Minneapolis.
