Embedded components

Components in our functional modules are embedded in monolithic blocks using high-temperature encapsulation compounds similar to those used in semiconductor fabrication.  This produces a mechanically and environmentally robust assembly and eliminates the need for a printed circuit board.  Components used in the modules are typically in leadless packages of the smallest available size.
