Hello Jon (?) Sounds like it's just plain too hot. The Panasonic VA series specifies a maximum preheat temp of 160C for

Are you doing a reverse leakage test? Also, some electrolytic caps require two (2) cap tests and should always have a leakage test last. The UIC verifier programming manual should explain this. Otherwise, contact UIC's tech. tele. support.

we used the ball bonding, just normal chip on board. as I know the the electroless Ni/immersion Au, the gold thickness is about 0.13um at most, what about chemical plating or electrolytic plating? any experience on it, thanks

Hi Experts, Pls help advise what is the expected range of PCB gold thickness over Ni (for ENIG/Electrolytic fabrication processes)? any referrence standards set by the IPC?

I have an Electrolytic capacitor which is 17mm in diameter and is 16.7mm in height. It is presented in a reel,44mm x 24mm. I want to know if there is a suitable feeder available to place this part onto a Fuji IP3. Thanks, Alan.

ok I agree there has been a confusion with terminology When you say electrolytic soft gold with a minimum thickness of 5-8 of Au, is there a standard that you spec this from ?

Ah, so that's where the knowledgeable authoritarian style comes from. It all fall's into place! Rob. ;-) (Former exploder of electrolytics, and gas tap flame thrower pioneer)

Don't have a picture but a ribbon lead is jaust a flat lead with no standoff capability. look at a SMT electrolytic cap for this lead type.

I would second the hot melt glue method. You do have to teach the importance of "more is not always better" and there will be learning curve, but it's a lot better at securing big clunky electrolytics than RTV. It's also a lot cheaper than chipbonder

Had similar issue with Omniflow. Was actually jostling tall electrolytic caps off of pads. Found that idler sprockets/pulleys needed lubed.
