Respected all;

I am currently a student at RIT and working towards my master's in Manufacturing and Mechanical System Integration with a specialization in Electronics Manufacturing.

I came across an interesting topic regarding the tooling and fixtures used for double-sided PCBA's and found some interesting products like Grid-Lok, vacuum support. My question is what the limitations of these tools when considering stencil printing operation and also where can I find research papers related to tooling and fixtures used in PCBA for double-sided boards?

We do use a company for custom fixtures, but we also make some in house.

The biggest hurdle for a board that requires a fixture to go through printing and SMT is that the board has to be the tallest thing. So any hold downs or locating hardware has to be below flush with the board surface. Also, if the fixture is to go through reflow as well, it has to be made a material that can withstand multiple passes through the oven without warping from the heat.
