Pressing apparatus for a semiconductor device

A pressing apparatus for a semiconductor device, comprising:

• a holding frame having opposite lateral walls spaced apart from each other in a transverse direction, each of said lateral walls having opposite front and rear ends, said holding frame further having a rear wall interconnecting said rear ends of said lateral walls, said lateral walls cooperating with said rear wall so as to confine a receiving space having top and bottom sides, said holding frame further having a bottom wall disposed at said bottom side, said receiving space being adapted for receiving the semiconductor device therein;
• and
• a positioning device including
• an elongate press block unit disposed in said receiving space such that the semiconductor device is disposed between said press block unit and said bottom wall, said press block unit having opposite end portions that are opposite to each other in the transverse direction,
• a pair of L-shaped coupling blocks, each of which has a first portion connected to a corresponding one of said end portions of said press block unit, and a second portion connected to said first portion and cooperating with the corresponding one of said end portions of said press block unit so as to confine a mounting groove for extension of a corresponding one of said lateral walls therethrough, said second portion of each of said coupling blocks being formed with a screw hole, and
• a pair of positioning pieces, each of which has an operating end portion disposed on said second portion of a corresponding one of said coupling blocks, a screw rod connected to said operating end portion and extending through said screw hole in said second portion of the corresponding one of said coupling blocks, and an abutting end portion connected to said screw rod and disposed between a corresponding one of said lateral walls and said second portion of the corresponding one of said coupling blocks;
• said press block unit being movable to clamp the semiconductor device against said bottom wall, said positioning pieces being operable to engage said lateral walls for retaining said press block unit at a desired position on said holding frame.
