If you are getting top side wetting, I doubt if this is a Delta-T problem. It also could be there is a lot of flux on the top side of the board stuck between the connector and the board. This is easily checked by fluxing and not running th eZ axi

Recently we have serious problem of our 0.5mm pitch QFP solder bridge. I check the viscosity of the Litton Kester paster. It's roumd about 700 is it too low. And do you have god solution about it? thanks alot

Check the pcb layers. Maybe it gets hotter in certain areas of the board. Most parts being wave soldered should be clinched, crimped whatever to avoid this. What parts are lifting?

Is there anyone out there who has used fringe pattern image projection vs laser triangulation method for solder paste volume inspection? Need some advice on which is better?

I have also come across this very same problem and found that our screen vendor made a mistake on our screen. Check the thickness of your screen it should be about six thousandths if it's eight thousandths then you are most likely depositing to much

Hi Ian- check out the ipc.org technet forum archives, there was recently a big thread about this very subject. There are some definite advantages in some situations to dispensing paste. Bill

Evtimov, Check them: http://www.mb-mfg.com/products/surface-mount-carriers Only for instance. All can remember material I was using was black and made of pressed fibers. It was hardly treatable as well. Regards, Pavel

Jason, First, check with the manufacturer of the flux you are using. They can tell you what board topside temperature range the flux is designed for. Some other info is needed for the residue part. Is it showing up on the same board, or different boa
