Maximum torque: Contact in motherboard, 3 in-oz MATERIALS Contact: Phosphor bronze Thermoplastic insulator: UL94V0 glass- filled polyester MOTHERBOARD Material: Glass-filled epoxy, FR-4 or G-10 Thickness: .093-.125 inch Drilled hole diameter: .0453 + .001 inch Copper through-hole plating: .001-.003 inch Solder through-hole plating: .0003-.001 inch Finished hole diameter: .040 + .003 inch Hole location tolerance: ee Compliant pin technology** VARIPIN Compliant section: When the contact is press-fit in, the section complies within the hole. Stress is absorbed by the pin, not the board, minimizing deformation of both the hole and the plating. Licensed under U.S, patent RE 29513. Assembly The connectors shown here are easily installed using simple tooling (available from ELCQ) and an arbor press. If desired, ELCO will install these connectors into the mother- board to provide a complete backpanel. Important: Building the hole accurately is critical to proper press-fit joint perfor- mance. The finished diameter of the hole is a reference dimension. Tolerances for all the factors in achieving that dimension (drilled hole diameter, Cu plating thickness, and solder plating thickness) must be observed. Any deviation (e.g. a bigger hole with thicker plating) may degrade the joint. ELCO can provide engineering assistance in specifying the press-fit holes.
