Do We Still Need SMT Adhesives?
Do We Still Need SMT Adhesives?
If double sided surface mount assemblies are the way of the future, should we anticipate a growing or declining need for SMT adhesives?

I have a hot air machine which I use for most of my assembly work. I recently have had to build a double sided board which has 2 IC's, one on each side and they both have a center ground plane which covers the majority of the package.

The problem I have had is, after placing down the smaller IC and turning the board over to place the larger IC, the smaller IC is dropping to some degree and loosing some contact with the pins and center ground. I have switched to do the larger component first then turn the board over and do the smaller IC. Same results are happening.

I have taped the first IC into place after soldering it down and turning the board using Kapton tape and it still slides around when placing the second IC on the board. I have never worked with any of the bonding material and am wondering whether this will take care of my issues.
