Hello, I am also interested in obtaining information on your de-panelizing machine. We observed cracked components from a 'pizza style' machine we evaluated. The nearest component center to the v-score is 0.25". Regards; F. Sun From: [log in to unmask] (PERARO_DJ) Subject: Re[2]: small pcb "V" score To: [log in to unmask], Pete Court <[log in to unmask]> Cc: [log in to unmask], [log in to unmask] (PERARO_DJ) Pete, I am very interested in learning more about the machine you are using to de-panelize V-Scored boards. A large percentage of the product we assemble is panelized and V-Scored. In order to facilitate the separation of the individual boards, the remaining web thickness is kept low, typically 12-14 mils. Obviously, using a mechanical cutter would allow a thicker web, which would provide us a more dimensionally stable panel array. Please send me the manufacturers name and number. Thank you Dominick Peraro ______________________________ Reply Separator _________________________________ Subject: Re: small pcb "V" score Author: Pete Court <[log in to unmask]> at 0UTG0ING Date: 5/14/97 9:31 AM James. How are you currently breaking out the v-scored boards? Our manufacturing guys use what is basically a powered, fixed, 'pizza style' cutter. The panels are fed in, and the blades run down the score line cleanly breaking out boards, thus minimizing any stress on the components because the boards are never 'bent'. I could find out more details on the machine if you're interested.
