Has anyone any experience in using Arlon thermabond as a prepreg between polyimide substrates and alluminium heatsinks, Does it really make any difference to the CTE etc ?

I'm looking for information on a company called AI Technologies. They make conductive adhesives and thermal management materials for attaching dice and heatsinks. Any feedback from users would be appreciated. Thanks, Chrys

Has anybody ever done a double-sided reflow with a Altera 240-pin RQFP on the bottom? The part has a heatsink in the top and weighs just over a half-ounce... Thanks in advance! -Steve Gregory-

That must be embarassing to explain the reason that a heatsink falls-off the board at your customer's site. ;-) We have found the best approach involves: * Work instructions that are clear, complete, and unambiguous. * Proper materials and tools to

Im guessing your using a PSA? We have had very little luck with this method of attachment as a standalone.Works great if you are using clips. I would suggest you look into a thermal adhesive.

Well that Genius did it on this BGA. It does have a heatsink and absorbs alot of heat. It just stinks because the BGA cost over 1000 and I really can not scrap a board. But that first profile does not look correct for this board with the BGA esp.

We think if you follow your suppliers instructions, you should be OK. Why not have your quality people rip a couple of the soldered heat sinks from the board to assure themselves that your soldering process is adequate? Give them a pair of pliers a
