Current laminating processes encounter high amounts of voids between a silicone adhesive and a circuit board. Voids will not allow for proper heat transfer and could cause the circuit board to overheat.
Arlon is the manufacturer of Thermabond®, a silicone adhesive used to laminate circuit boards to heat sinks. Arlon wishes to expand sales of this product by introducing an improved method of applying Thermabond®.
Our goal is to design an automated process that will create a void-free bond between a silicone adhesive, a circuit board and an aluminum plate.
