if you don't mind supplying me with your fax number, I can fax over some considerations that we have used for panelizing boards. --Dean Lillibridge NEWvENTURE TECHNOLOGIES (860) 253-7057 -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of bbarr Sent: Wednesday, August 15, 2001 1:46 PM To: [log in to unmask] Subject: [TN] Panelized Boards I have a 3.5" x 5.5", .063" thick board we will be building in somewhat high quantities (3,000+/month). This size board is just on the edge as far as having to put it into a basket to run through our in-line aqueous cleaner to keep it from moving around. I do not want the operators to have to put this many boards in baskets during production runs. So, my thoughts have turned to panelizing these boards, perhaps in a 2x2 arrangement. This would go through the cleaner with no problem. I do not have a lot of experience in the best designs for panels. What are the advantages/disadvantages between v-score and tabs? If using tabs, how many are required to maintain the rigidity of the panel during reflow? Does there have to be a border around the boards? Are fiducials required on the panel in addition to the fiducials already on the individual boards? Any other issues I may have missed? Thanks.
