The Zephytronics unit does not have the power you need. Their process is based on low temp soldering. Companies like PACE have preheat units that will give you more power and control. I see more Zephytronics on the shelf in my travels than any oth

All I got to say is a bowl and spoon and mix it up a little before u place it on the stencil. That works fine on our end all the time.

FYI AIM has a patnented in-tube mixing propeller. Crazy, but it actually works.

Can you use one of those hot-dog rollers (cookers?) you see in the corner convenient stores to keep the paste tubes moving to eliminate the separation? Ya know, the cookers with the week old hot dogs on it that are all shrivelled up?

By looking at the solder balls they have not joined with the other particles that are alongside them. suggesting that they did'nt reflow. But they could very well be as you suggested, reflowed and ejacta from the process. We have been experiencing

Use a spray fluxer, like those used in wave soldering. Search the fine SMTnet Archives for supplier names. We understand that spray fluxing is significantly different than dispensing. What do you want/expect to accomplish by dispensing liquid flux

Excessive Time above Liquidus will cause a solder joint to become extremely brittle. Any shock or stress to the joint can lead to a failure.
