X7R >Z5U,Y5V Greater means less likely to crack or in other words NP0 is better than X7R for crack resistance. Don't think that there is a set formula. There isn't! I cracked ceramic resonators at 0.050" from the board edge with CAB M2 and M3 dep

CK The term that you're searching for is: "Singulation" the process of die punching circuit boards with a hydraullic press. [Although the very nice people that sell "saw depanelers" call their equipment singulators. We assume they do that because e

Smells a lot worse even with good extraction. Key things to look out for is laser life on your thickness and layup of panels compared to spindle motor life (Typically 10,000 hours, or 2 years for us) and cost of replacement lasers. We get spindle

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

Three main groups of depaneling equipment are: 1 Scoring: Limited to straight edges and mainly 90� angles 2 Routing: And a cloud of dust 3 Singulating: Hard tooled by board To get started understanding the suppliers look here: http://www.cassembly.c

For clipping off small boards and small quantities you can try Simonds. With no components and for longer straight cuts a shear would be more appropriate. How about the various de-panelling machines? The answer could be more specific if you would te

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 have a 2-up panel measuring about 8" x 8" with a score for depanel throuch the middle. I see warping after reflow of the panel (bending in/about score line). The board is not framed (i.e., supported) during SMT reflow other than on the conveyor thr
