1. What size panel does your PCB fabricator run? There is software that will optimize your yield. 2. How is the assembly de-paneled? There may be an .092" or more between PCBs. V-score has less waste but clearance from the score is required. 3. An 18x5 may print but a 20 x4.5 may not. Can your handling equipment, magazines, conveyors work with a 18" long PCA? Placement machines may have a problem reaching all the locations, additional feeders may be required to have the head reach all the points. Some machines have a large placement rate drops due to the panel configuration. 4. Test OK with this size? As usual what makes sense is dependent on your suppliers, current equipment set and volumes. ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
