Summary: | An interposer having one or more hollow electrical contact buttons disposed in a carrier. The interposer is formed by disposing sacrificial posts in vias of the carrier. The electrical contact buttons are formed on the sacrificial posts by a metallizing process in desired pattern using a mask. The sacrificial posts are made of a material that thermally decomposes upon application of heat without altering the carrier or the electrical contact buttons. |
