I have checked and rechecked all my dimensions on the capacitor which is a 402 size. The manual says that the center is incorrect. Need some help to figure out why it is throwing this part away seeing it passes a vision test. Any help would be gratef

Values and range definitions on your profile attachment are for LF paste not for Tin Lead. Please recheck and redefine, so we get the correct values. Also, which location is the QFN?

If you believe your picture is in the middle and is not skewed, than go to your basics and recheck your fiducial locations and detection. Sometimes these machines recognize something around and give you this error. Try program with isolated pads and

Hello all, Are BGA's easy to develope shorts? If a process is stable and all of a sudden you get BGA's shorting out on you, what might be problems? We've checked our solder paste amount, and we've rechecked our reflow profiles and nothing has chan

Use T5 solder paste Make sure you dont have too much paste, usually 1 time printing instead of 2. Make sure the component is baked before production. Re-check your profile on the reflow. Could be also a bad pcb edit, nothing you can do there.

Off contact is generaly less favourable than on contact printing. print height becomes a issue towards the edge or foil clamps. If you Had little or no issues with your previous board vendor re-check your specs you supplied to your current vendor. If

We used to have a UP3000. Long time ago so I'm rusty but isn't there a setting for fid correction that you an program to occur after each board or after 5, 10, etc.? I thought I remembered doing offsets on ours as the camera was a little wacky (old

Hello Rob, I was able to get the machine to zero, apparently replacing the circuit board on head 2 conflicted with head one even matching the jumper settings to the old board. Once I marked the head as not mounted, head 1 zeroed. I re-checked the ju

Hello, I have a capacitor that doesn't form intermetallic joint with SAC 305 solder paste.The board is ENIG. Solder melts and forms good intermetallic joint with the PCB finish. However, capacitor can be removed with physical force - it looks like a
