PCB Offset

PCB Offset | 3 May, 2000

If I have four PCB's in a Panel with four different angle of rotations (0, 90, 180 and 270 degrees). What would be the formula for my Offsets? I am trying to compare our techos method of programming the Chip Mounter as I noticed that he can't have that product running on our machine coz we do not have the operations manual of that machine (we lost it). Machine is an MV100 panasert.

thanks a lot,

Greg, at least on three different brand machines, I was working on, the offsets rotated with the board. If you start out at 0 deg. and the offset in the top left corner than it is on top right at 90 deg., bottem right at 180 deg. and bottem left at 270 deg. After that you add the distance from one pattern to the other. Stefan

Greg,

sorry for not being able to help with the programming issue, but there's something wrong with the situation you're in. You shouldn't accept answers like "no book, no program". Panasonic must have a strong customer support. Just call them, they are in the best position to help.

Good luck, Ioan

Greg, Ioan seems to have the best advice. I would imagine, if you identify your zero point on the board, you would just measure from zero to zero after the necessary rotation has been completed. But, I am not familiar with the software used. Why does your tech need the manual anyway? No experience?? No tech!! That's just my opinion, I could be wrong!!!

Panasert tech support is 800 308 0891. It is 24 /7 and offers pretty good service. On the MV100 I'd ask for Pete Turner.

Jax, I agree completely. In fact even if the Tech didn't know exactly what to do he should know HOW to align resources to solve the problem. This may include ordering a replacement manual, attending service / programming classes, calling technical support or even having the machine manufacturer create the "base" program for you.

And by the way, your not wrong!

Greg, You describe the Panel as being made up of 4 PCB's each rotated 90 degrees to its previous circuit. If this is true, the placement rotation changes enough that it would probably be best to define the entire panel as a single PWB. If you wanted a formula for the placement of multiple circuits you would first have to define your board of origin and the order in which the following boards are populated. Then define an increase or decrease in theta by 90 degrees. I am not sure whether or not the MV100 has this capability, but you might want to try that. Whether your tech is capable of this or not, will tell you if he or she needs to attend more training on this machine. I wish you the best of luck. TNT
