Dye and Pry Testing

Dye and pry testing procedures depend on the ability of a low viscosity dye to be able to infiltrate a fracture while beneath a high vacuum. In general, this vacuum is applied for many hours and then preceded by a high-temperature bake. That way, it can cure the dye. Then, the BGA or QFN is removed mechanically, and the interfaces are analyzed for any dye remaining on the pad’s surface.

Upon this closer look, if the bonds appear to be intact, then it means that the dye will not stain the pads. On the other hand, if there is a complete or partial fracture, then the dye will add a layer to the fractured surface, and the next inspections will be able to see the solder joints that have been fractured.

Uses of Dye & Pry Testing

Dye and pry testing (also known as a dye penetrant test) is performed as a way to identify discontinuities that are discovered below a variety of SMT components. It’s important to note that while the dye and pry testing is technically destructive, it is used in a positive way as a cost-effect measure that analyzes solder connections of bottom terminated SMT packages and BGAs.
