Russ, I didn't use a stencil for my experiment because I was not sure that the solder mask idea would work. Now that I have treid a few experiments I feel dangerous! LOL. I will not have to use a step stencil, I will just mask all the parts. Lik

Good morning, MPM AP25 we have is equipped with dedicated vacuum support only, no side snuggers. Also we had a lot of issues with fine pitch paste deposition due to this poor support. Vacuum support can�t fix wrapped boards properly causing a lot of

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

Davef, You have a good question. If we had perfect design engineers out there that would use the proper component spacing and not put SMT parts between and around thru-hole parts - glue and wave would work perfectly. I have done this with great su

Here is the problem : We have 2 AP25 printers with dedicated tooling. After we run side one boards through reflow, we get some warpage in our boards occasionally.(Sometimes we get a lot of warp depending on the geometries of the substrate) When the

What you describe is the X snuggers fitted into the workholder which do need either a flat board or good vacuum to work. There are several solutions. One solution you can try yourself is to use Vacuum cups, ( bellows type) designed into the workholde

There should be a "Tracking" button at the bottom of the screen that you can just tab over to, then press the green start button. I have not worked with the 730, but it is that way on our 740, 750, and 760 machines. Alternatively, you can move the cu

“For a number of years now, work has been proceeding in order to bring perfection to the crudely conceived idea of a transmission that would not only supply inverse reactive current for use in unilateral phase detractors, but would also be capable of

Hi, your machine is exactly the same configuration as mine. I even think we both bought them from the same seller ;-). Anyway, it's BLOCK-I with (most probably) USOS V1.4.14 software running on OS/2. I've registered the software with UIC for 400 E
