Hi, I was told that there is a reliability problem with a 30 to 50 percent champagne voiding on chip components. What is this? first time I've heard this terminology. can you help me? regards,

Hi, champagne voiding is the term for small flux enclosures in a solder joint. Under X-ray that looks like the bubbles in a champangne glass. Marcus

The voids are between the interface of the pad and the solder joint of component chips. I have a good thermal profile and this problem occured only on certain product so since we have some common components, component termination contamination is no

Normally I am Champagne taste on beer budget. But I am beginning to want a no nonsense pick and place machine and willing to pay for it. But I feel there is a disparity as some machines run ~$100k (universal/hanwa) and others run ~$400k (Yamaha/Fuj

I never understood the statement "process indicator". The 7095 committee used that wording but didn't explain it. Other than really unusual cases such as champagne voiding, BGA voids are not a reliability issue. A half dozen studies have come to t

We saw this condition over 3 years ago. It sometimes is called "champagne bubbles". The intemetalic formation is interrupted due to the micro voiding reducing mechanical strength. I discovered this on lead free test vehicles for a major computer

What's sad is, it really happened. I won't bore you with the details again. ;) Lloyd, I would love to have a nice Hi Scope too (I think Cchunks works for one of those big champagne and caviar corporate entities ;)) but if you can't swing it, at leas
