Custom Fabrication of Saint-Gobain Silicone Press Pad Sheets for the Circuit Board IndustryDemonstrating our ability to work with highly specialized materials in an efficient and cost-effective manner, Eastern Industrial Products, Inc. custom fabricates Saint-Gobain silicone press pad sheets, which are used as a conformal medium in the manufacturing of flexible circuit boards.

Working from customer supplied specifications, our team of highly skilled engineers has developed a manufacturing process that utilizes our auto balance hydraulic full head press to convert roll-form Saint-Gobain #4444 silicone into 24″ (L) x 18″ (W) x .062″ thick sheets, which are both visually and caliper inspected to verify that they adhere to the tight ±.005″ tolerance requirement. To improve the surface quality of this static-free, high-temperature, and high-pressure resistant material, each sheet is individually washed with a unique cleaning solution, then packaged with paper interleafs to prevent the sheets from sticking.

Our ability to efficiently convert this elastomer compound from roll form into these 24″ x 18″ sheets has helped our customer streamline their operations and optimize their inventory, all while providing them with a notable 8% cost savings. We are currently shipping 750 sheets annually on a just-in-time delivery schedule.
