I agree, the only way to "truly" inspect a QFN is with an X-ray. But this might be over-kill for him. He asked about soldering, not inspection. We use QFN's regularly and you can inspect these parts from the side to see if they are soldered. Unfo

Are you running individual point soldering on each component lead, of are you drawing lines with the solder fountain to increase the speed of the process? Could be that if you are drawing lines, coupled with the very low flux levels you say you are

I'm with Dave on this one. In my opinion, it'd be much more cost effective to add an alignment legend. Speaking from experience, as I've hand placed many BGA's, all you really need to do is hit the pads. Even with Pb Free Chemistries, the part should

I'm guessing you're running small batches of boards on the MyDatas. We had the same issue with management when they decided to save on parts (not realizing it cost them more in time and more frustration for us). We had Agilis feeders so that helped.

On mixing paste: There could be a lot of hand wringing about the need to minimize solvent evaporation, flux separation, and chemical activity. [True alarmists will throw in oxidation of the alloy.] But I think the real concern is a change in viscosit

Hi, You can go a long to answering that question yourself - what do you need to see? If you are lookig for the normal stuff like bridging, opens and voids you dont need anywhere near 130-160kv. I have just completed the same excercise and we have s

I would agree with Sr Tech..Grid lock and systems like this can be used on the Ekra, MPM and DEK printers also can be used in Pick and place depending on the density of pin. If you choose the method of printing out a 1:1 photoplot. Glue it to a piece

Yes, I have experience with table model of ScanSpection. Machine work fast, but process of job program making is very slowly. If you each time have elements from one supplier - this machine for you. But if you have many suppliers of components - it's

We have a My500 at out plant. We are high volume and low to medium volume. It is a great machine and is a great solution to some problems that a conventional screen printer cant get around. For example, we have some producets that are not flat on
