Just to get the simple stuff out of the way. Make sure that no one has changed the machine nozzle data to a different type. Then try actually changing the nozzle data and putting that type into the head. If this passes it will at least eliminate the

How you pack & ship your board level assemblies? I mean assembled PCB modules without housing etc. We often have small assemblies (cigarette box size) in the $5-15 range. We put them the (dreadful) red bubble bags and then on carton trays with carto

HSP nozzles get pushed back up into the head by a cam with a pneumatic brake on it. Make sure this is functioning properly. It is not uncommon for the MAC valve that actuates the brake to get flaky = replace it. Also, the nozzles are mechanically
