Khalid, Just from experiance the actual would be 0.4mm but the inspection size would be 0.3mm. This should not matter since you should be able to pull up the spec sheets on any part you place.( All you need is the Vendor and the manufacting part numb

check the archives (keyword="16 mil pitch") and also consider 45 degree pattern printing. Regards.

We have to mount our SMD devices 0.1 to 0.4 mm off the pcb PCb substrate to compensate for thermal stressing in a Space enviroment. Has any one any ideas or contacts for dissolvable pads. this only applies to leadless components

Has anyone Ran parts on the CPII taller than 4mm? If so, what adjustments were made to the machines to accomodate such a part?

We use Samsungs and have never encountered a 24mm with 4mm pitch. I actually have Samsung coming in tomorrow and we will reply. Russ
