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

Hi! Can anyone tell me what is the min spacing between PCB edge & land pattern to avoid cracking of components due to mechanical stresses caused while depaneling with cookie/pizza cutter. Thnx!

We are currently looking for a way to measure pcb stress during our assembly process. We would like to get an idea of what amount of stress (flex) the boards are undergoing. We would also like to use this to compare a few different processes--for e

I'm requesting assistance in developing detection and containment methods for an issue with an SMD ceramic resonator (Murata CSTCE-G-A family). The returns have external visual cracks that originate at the termination and run at approximately a 45 d

Steve, I have also requirements for this machine. I was able to evaluate some of these machines but the result was not ok. It burn the PCB especially if you have 5mm thick PCB. If you can find one that doesn�t burn PCB please let me know as I am als

if you have a budget for new machine, laser depanelising is pretty good for flex PCB as no physical stress on PCB like mechanical routing, thus fixturing is easier and less prone to moving the flex while cutting. Laser systens can also cut FR4 standa

Wow. And I thought I was the only one having problem with ceramic capacitors.I too am having problem with cracking ceramic capacitors 1206 package.We changed vendors and still having the same problem. I had to reverify my entire process and I had to

You might want to call CTS and speak with Jim Welch about their depaneling system. His phone number is (630) 293-9470 Wayne

After you depanelize your product, use the remaning "frame". Just set your panels on the "frame" before reflow. That will give some extra support. JB
