This depends on the model. Most machines and turret style typically overstroke .2mm with a force of 250 - 300 grams of force. the reason for the over stroke is to place the component into the paste. This can be adjusted through part library manipul

you should be able to get the force requirements from the connector manufacturer. Both the minimum and maximum forces used in the pressing cycle should be recorded to know the connector is properly seated without excessive force that can damage the

Peel Back Force
