SHP was founded in 1988 by Jack Pollock to meet an industry need for sealing system design/manufacturing capability.

For too long, feedthru seal manufacturers and users treated these devices as a commodity. Lost was the need to consider feedthru seal design as part of a larger system to properly consider interface issues such as stress and related reliability.

The result of this trend was a long history or poor results with hermeticity of soldered hermetic packages using feedthru seals. These problems were compounded by the transition from ferrous alloys to high-expansion non-ferrous alloys such as aluminum as a material for large scale integrated packages.

SHP first developed the aluminum compatible seal, which has taken aluminum hermetic package reliability to a new level.

Numerous additional products have been developed since, including miniature aluminum compatible EMI capacitors, kovar compatible capacitors, kovar compatible SMP connectors, micro “D” connectors both Solderable and laser weldable for aluminum, kovar and stainless steel and other materials, the hermetic SMP coupling for vacuum chamber application, high-frequency hermetic waveguide window, high-rel window design for hermetic detector and laser applications.

SHP continues to provide engineering services to its customers to achieve the highest possible reliability in the area of hermetics. Our staff of engineers is highly qualified in all areas of seal design and manufacture, but also knowledgeable with critical issues involved in the use of seals in electronics packages.

SHP is unmatched in its breadth of standard products and application knowledge in the hermetic packaging area. Since we design and manufacture every type of glass sealed product and the packages in which they are used, as well as direct-glassed packages in various materials, we are in the unique position of offering essentially all possible solutions. This allows us to optimize the design approach for cost and/or performance and provide our customers with options from which to choose.
