Close but not to close, would have to be the spec. Or depends on your separating technology. Prerouted boards on a panel, you could go right up to the edge. V-grove you will need more distance, maybe 2mm's or more. The distance from the panel edge to

Hello, I would like to ask you about the minimal distance between components and border of pcb especially V-cut to avoid crack of component during depaneling? I need some standard (IPC or something) where is this defined? Thank you for your support

Thank you for your answer, but I am litte bit confusing. There are parameters of V-scoring but with put values. How can I get values for V-scoring for pcb 1,6mm thickenss. Thank you. M.

It depends. Are you hand breaking them, rotary knife or linear knife? Hand break you want to be about 5mm (and it isn't a great practice even then) with a rotart knife you want to keep parts probably 3mm, especially capacitors. With a linear knife we

If your pads are long enough you shouldn't have a problem, the pins on the connector are curved up(away from pcb)and will plow solder paste to the end of the pad then it will wick back up the pin during reflow. if you have a second stencil for the bo

There's no easy answer. It depends on: * Thickness and size of the PCB in the array. * Means of separation. * Type of component. SMT components are more sensitive to the forces that need to be applied to separate the PCB. * Type SMT device. Ceram
