Sorry all I know is that storing the paste Tip down the flux will run to the tip of the cartridge so will be runny initially then dry up as you use the cartridge. Unless the Rheopump mixes it before application

Flux is less dense than metal so it 'floats' to the back NOT the tip when the tubes are stored tip down.

Yes sorry you are right so you have answered your own question anyway. Dry to start runny at the end

If you're having trouble with a specific board, double check your Pattern, Diameter, Color and Scan Area under the 'Mark Data' tab. You can also try setting the Pitch Tolerance to '0' in the machine configuration. Good Luck, Bill

I have several QFP-100's that I need to rework. Obviously this is going to be tricky with the component having a pitch of 0.5mm. Could somebody offer some suggestions for a decent, yet cost effective, rework station?

Steve, you're correct. Placing and dragging 20 pitch is tedious and easily leaves bridges behind the heels of leads that can be difficult see.
