The resultant thin compliant spring contact can deform a small amount as the spring contact is then pressed against a compatible mating contact surface in an overlying layer.

Before mounting on the board, at least one connecting pin, preferably every second connecting pin, of the package is bent inward by a bending tool to achieve an offset arrangement of the connecting pins. The package is preferably mounted on the board using the bending tool. Since every second connecting pin is not bent inward immediately before insertion of the connecting pins, no subsequent corrective alignment of the offset connecting pins is required.

Abstract: Efficient methods for lithographically fabricating spring structures onto a substrate containing contact pads or metal vias by forming both the spring metal and release material layers using a single mask. Specifically, a pad of release material is self-aligned to the spring metal finger using a photoresist mask or a plated metal pattern, or using lift-off processing techniques.

When the release material is electrically conductive (e.g., titanium), this release material portion is positioned directly over the contact pad or metal via, and acts as a conduit to the spring metal finger in the completed spring structure. When the release material is non-conductive, a metal strap is formed to connect the spring metal finger to the contact pad/via.
