摘要 A molding machine for encapsulating electronic devices mounted on one side of a substrate, and having a ball-grid array, pin-grid array, or land-grid array on the opposite side, has a two member biased floating plate apparatus to compensate for variations in substrate thickness, and a gas collection/venting apparatus for relieving gases emitted from the non-encapsulated underside of the substrate.
