yes, You need tell us how the PCB and board designed, size, material, how de-paneling the PCB?

We have recently purchased equipment that would probably solve your problem. We are using 1.6mm pcb material 1/3 of which is left unscored. When the pcb is de-panelized there is no damage to any components and we have cut our break time in half.

I can not tell you what the actual stress limits are. I can tell you that de-paneling PCB's by hand is a very poor choice. I have seen numerous accounts of cracked caps, resistors, and LED�s due to incorrect de-paneling procedures. I would recommend

Hey, thanks for your feedback, this was our initial thought however our process engineers don't buy this. Although they are close to the card edge this product only has de-panel length wise which is perpendicular to these capacitors. The PCB its

#1) Is the card in panel form: (Y)/(N) #2) PCB thickness: Thin card: YES, Thick card: See above. #3) is the PCB warping during reflow? (Y)/(N) #4) Is the PCB Symmetrical is shape & size? These are just some of the questions you need to ask yourse

Background on the PCB: Thickness: .032" Material: Standard Fr4 V-score: Leaves .016" (approx .008" cuts on either side) We are having some issues on these boards where the edges are delaminating all the way to the copper during de-panel. Now, we are

Grandpa, You got it - Identifying the bottleneck operation is the key. The secret is to design a tool can predict accurately where this bottleneck is. In your formula you can use machine process time, PCB transportation time, part trim time, part in

There are different options for de-paneling routers. There are two basic types, in-line and stand-alone. Do you need in-line for high volume? The stand-alone systems have manual insertion trays, one or two trays. Also, after de-paneling or laser ma

I would look at your de-paneling process. How are you cutting the boards? This could be inducing mechanical stress on the component; especially if the part is close to the edge of the pcb and perpendicular to it.
