ERNI’s Board-on IDC system offers the possibility to optimize cable connections in two ways. The compact size reduces the requi-
red area on the board and it is more cost effective than a conventional female – male connection.
Note that the Board-on IDC connector is to be soldered to the PCB before assembling the cable.
ERNI recommends the following:
• A layout proposal indicating the restricted area.
• Use upper and lower tooling to assemble the cable to the connector. Use a flat upper tool which covers the cable guide and is
mounted to the press ram and a lower tool that completely supports the area beneath the connector assembly.
• Insert the entire PCB into a fixture for the best results so that one may concentrate on the operation of the press and holding
the cable. The fixture should be fixed to the press base and have a method of aligning the PCB within the fixture using the
perimeter of the PCB and/or alignment pins.
• Important consideration must be given to the assembly tools available. When using a
hand lever press it must noted that the PCB outside edge (or the fixture edge) to the
connector center is smaller than the distance from the throat of the press to the
connector center (dimension ‘X’).
• Adjust the press shut height to 5 mm [.197"].
Additional visual monitoring of a completed assembly is achieved when the recesses are
visible and the slot between the cable guide and the connector is evenly shut.
• Neither the PCB nor the components may be bent during the press-in process.
• The flat cable must be inserted in such a way that it protrudes on the end by 0-1 mm.
• The flat cable must be inserted 90° to the connector.
