Is there a way to have one nozzle on the HSP Chipshooter 4796 to use a higher force of vacuum than the other nozzles? For instance, an 8x4 embossed feeder has components that are wedged hard into the plastic and cannot be pulled out with regular vacu

First thing is you should be using a 08MPFX nozzle for a 0603 part if you are using a flex head. Then to check the vacuum you should have received a vacuum gage with a nozzle tip that fits on to your spindle and then you turn on the vacuum in diagnos

Moisture barrier bags are polymer coated foil so are nearly gas impermeable. There's always some coating left at the weld (or it wouldn't stick) so they're not completely sealed but that's as good as it gets. Usually people use the vacuum to remove
