Specifications of testing force are not fixed, but (incase of wave soldering) the value should be at least 120-150 % of the force the wave. So for small chip components we assume that the force from the wave on the component is about 3 Newton, this m

Your concern should be do you have a glue process that can keep up with the FCP6. We ran a GL541 in line with a CP643 which the glue machine was actually a bottle neck because if you run SOIC's which require more glue dots then it will slowdown the
