  • Publication number: 20220230985
    Abstract: A jig for manufacturing a semiconductor package includes a bottom piece and an upper piece. The bottom piece includes a base, a support plate, and at least one elastic connector. The support plate is located in a central region of the base. The at least one elastic connector is interposed between the support plate and the base. The upper piece includes a cap and outer flanges. The cap overlays the support plate when the upper piece is disposed on the bottom piece. The outer flanges are disposed at edges of the cap, connected with the cap. The outer flanges contact the base of the bottom piece when the upper piece is disposed on the bottom piece. The cap includes an opening which is a through hole. When the upper piece is disposed on the bottom piece, a vertical projection of the opening falls entirely on the support plate.
