Insulation distance

Product concerned: Sdram memory. Due to the net resistor size and shape (0603, the lead of this component is very close to some vial hole. What is the minimum clearance we must have between a component lead and a pad or via ? For the pcb design th

Plated hole to copper spacing

I am having problem with plated hole-copper spacing. I don't know if the gap between plated hole and copper can meet the capacity of PCB manufacturers. My board have 0.5oz copper weight on outer layer and distance of 0.177MM between plated hole and c

Would this dimension be the same if the board is panelized and the board has break aways? Nancy

Min Hole/Pad distance to edge of PCB

Assuming agressive design rules what is the minimum distance I can get away with between the board edge and a SMT pad and between the board edge and a plated mounting hole ??? (The board is only 1"x2" and the mounting holes are 80 mil dia, 125 mil

Stu, it is good you know that there are limitations and you want everything. Wish our designers work like that. So, the limitations we impose are dictated by the rails of the insertion and dispensing machines. Normally a .150" keepout will make a s

Bingo!!! By panelizing and adding breakaway rails (as Nancy says), Stuart can pour copper up to his board fab's tolerance from the board edge. Traditionally, he just wants to make sure no copper shows on the edge of the board. Then again, it's his
