ABSTRACT:
Apparatus for releasably securing a flexible printed wiring board in preparation for electrically connecting an electronic component thereto may comprise an air permeable platen having a substantially flat front surface and a back surface. Vacuum pump apparatus in fluid communication with the back surface of the air permeable platen produces a pressure differential between the back surface of the air permeable platen and the front surface of the platen. The pressure differential securely holds the flexible printed wiring board flat against the front surface of the air permeable platen.
