cookson has something they call "cool caps" that reduces the delta T across the component top surface, something you might wanna explore to reduce the delta T even further....FYI, I am not associated with cookson in any way

We are using AIM WS300 solder paste and are experiencing excessive voiding on our BGAs. We have exhausted reflow profile alternatives and just can't beat the voids. Has anyone had success with this paste on BGAs? If so how?

Ray Prasad is good reading, the other three are lame and not worth the money. Ray also has other services if you're interested.

I would recommend that you search this site. There has been a LOT of discussion on this.

It looks to me that your reflow profile is not hot enough. Seeing the granular structure of the solder paste still on the board would indicate the paste has not reflowed entirely.

my first thought was that too, but all the other components on tha board have reflowed properly. I have tow test boards, one with Imm Sn and other with Imm AG. on both these boards only the QFP has this solder phenemenon

Way to go! Now my favorite "deep space nine" website has turned into a "URL" fanclub. You should know better than to post that HERE!

Hi. I am trying to find out the minimum copper thickness I should see on a through hole barrel. The board has 1 ounce copper and the board thickness is 0.062". I am finding thicknesses of 0.6 to 1.2 mils. Thanks, Mike.
