Question, on a pc board that is .060 thick what should my v-score depth be? WE are currently using a v-score that leaves a remaining web of 15 thousandths is this adequate, or should we be going deeper?? thanks in advance

Does anyone know were I can find acceptable board scoring specification for V scoring of board break aways. I was unsuccessfully in finding the information in IPC specs..

I agree with the other posting about V-score but don't forget about a Wand punch if the application is high volume, also IPTE manufactures a cutting system that doesn't require any V-score, it just cuts the boards apart with a diamond wheel.

Why do they say to specify the depth of the score, rather than the thickness of the web? How does the scoring equipment work? Is it two blades that you can set the separation distance? Or is it one blade, that you have to run the board through twic

IPC spec is V-score shall not be more than 1/2 board thickness. They should be V scoring 1/4 off top and 1/4 off bottom equally.

Hi all, The majority of score machines used today have a top cutting wheel and bottom cutting wheel. This way they can score a line in one pass and saves on programming time, Panels are typically scored in one direction first and then the panel is r

We have some pcb assy's that are panelized and very narrow brds. We feel that some of the smt resistors may be becoming cracked when breaking them apart. Though we are scoring them deeper here and have requested our brd house to score deeper, is ther

I have never heard of heating the board for separation. You may want to try some of the following. -Using a roller cutting type depaneler helps reduce the stress. -Using a combination of routing in areas with components near the edge and v-score th

So, now you know the tolerance that you and the board fab have in the area of the score line. For more, look at: * Accusystems [accusystemscorp.com] site scoring section for their FAQ. * Merix [Merix.com]: Designing For Manufacturability (DFM) Manua
