Zusammenfassung:An apparatus is described. The apparatus includes a back plate, where, an electronic circuit board is to be placed between the back plate and a thermal cooling mass for a semiconductor chip package. The back plate includes a first material and a second material. The first material has greater stiffness than the second material. The back plate further includes at least one of: a third material having greater stiffness than the second material; re-enforcement wires composed of the first material; a plug composed of the second material that is inserted into a first cavity in the first material, a stud inserted into a second cavity in the plug. An improved bolster plate having inner support arms has also been described.
