Thx for the replies. Acutally I am doing a process related study to see whether the process (pcb depanelling)can induce crack to an MLCC. After depanelling, I will do a thermal shock on the MLCC based on IEC 384-1, that is, five cycles of 30min at hi

Specs for Bow and Twist for PCBs (IPC-A-610C, 10.6. There may be an update by now). I also have a note in our quality guide referencing (IPC-TM-650, 2.4.22) and (MIL-STD-105D). In summary, a PCB should not bow more than 0.040" with all four corner

Hi, In the CP6 propers, there are values: PCB Check Position X, & PCB Check Position Y. These are the servo counts that the X/Y table moves to when checking if a PCB exists on the table. Your sensor does not detect a PCB, probably because when checki

Hello everyone! I have a problem with PCB, we detect that some contamiation apear (dark spots similar to glue or underfill) we detect that this element is Policarbonate. I don't know if on PCB fabrication process some policarbonate are used. We alr

You should be able to check the sensor, most had have the red light to indicate that a PCB is being detected. Depending on the version of software it should tell you within the manual control option too

Hello, I am new in this forum and also new in PCB manufacturing. now we have issued about silver open and short. we can detect this defect after auto check process and its to late to save our PCB. Is there any way to detect silver open or insufficien

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

Avichai: What kind of PCB are you using, when do you detect that shift (right after placement, before reflow, after reflow), does the shift always appear to be the same or do you see a variation, are you able to identify the process-step where it hap
