Perfect for daughter boards
A pneumatic portal press (Unipress 500PP) can develope a high insert force (56kN) and it had a large ram to insert a complete row of connectors on one stroke, like on daughter boards.
Extract and repair
If no high insertion force (<32kN) is required and the number of insertions per day is limited then a manual press could be a good solution. In combination with the right repair tool/adaptor, it could be also very usefull to extract inserted connectors out of the pcb and to reinsert a new one without desturbing the normal production flow on your high volume production machines.
