It all depends on what type of board you need to solder. If your boards are small in size and low thermal mass and your conveyor speed requirments are normal, then I'd say the OmniFlo 7 will do the job. It has a max zone temp setting of 280C. The cur

Hi: We started many years ago with totes on shelves 30 reels per side. Then we moved to 12" shelving with reel boxes. 5 reels per box. It was cheap and each was a single location. Great for finding and decrease cycle time in finding parts. Our wh

I don't work on quads but I can give you some things to look for... Each of the moving axis work off a motor that is controlled by a "drive". Some of these drives have a fault or error output that is connected to the motion controller. One of your

Mike, Right down all the settings you have for your machine (this may take a while). Also back up the programs you want to save. Now....if i can remember correctly.....when looking into the black computer box from the back of the machine...in your bo

ING, you had to nake it difficult didn't ya! It appears that all of your parameters are okay. When you state that "sometimes there is a residue" is it liquidous or dry? Is your spray fluxer an ultrasonic or a spray gun head? You may not be getting

We use 10% reductions when either the aspect or area ratio will not be affected. We will utilize a 1:1 when necessary. We place a lot of those little Rnets down to 0805 size .5mm pitch and do not see any problems. We use 6 mil stencils almost excl

I wouldn't raise the temps just slow the conveyor, You need to get the PCB "soaked in". It seems as if you are applying more thermal energy than the PCB can accept in all areas. Does this oven have convection heating? Hopefully so. I have found t

Glad to hear a little success from ya Duckmann! i have stenciled mask in the past and I can tell you that stencils are expensive. They are basically a step stencil, you will need full thickness for the area(s) you are going to apply mask and you wi

Mrduckmann2000: Why do you want to do this? * Removing a non-washable / peelable temporary solder resist [TSR] is going become very tedious, because they do not release well from small / tight / isolated features. * Clay from washable resists will
