Are there any tricks to cleaning a stepped stencil while in use. There seems to always be paste left behind around the recesses of the stencil. We have tried many different wipe combinations and don't seem to be having much luck with it. The machi

That's a pretty vague question, especially if you count "ID" in the time. In a world where you have AOI or in circuit testing telling you which part has to go, limited thermal mass to contend with and decent equipment, I'd say thirty seconds. On my

I am not an objective candidate for a Machine manufacturer selection, I only know Fuji's. But, it sounds like a good fit for a Fuji XP series machine. And of course, I will try to find a good one and install it for a fee. The price of a used XP va

Hello All. Another question about programming if anyone could help? We are current placing BGA's and it places them fine but we have noticed it doesn't spot when a ball is missing. We have adjusted the settings so it does reliably spot the missing

with 0.5mm pitch I wouldn't go too fast. Check your separation speed as well as your print area(may be you can drive your squeegees 1-2 inches less). Some pastes like Alpha like very fast separation. so you can win another 2-3 seconds from there.What

One thing to be certain on the spring action of your tools is the direction of travel. With the new black tools the tube can seem normal but the slider is retracted instead of extended. This happens when pulling or installing tips. it is a very natu

We build new tools and have rebuilt hundreds of Mydata tools over the years. Ours have a key in them so you do not hurt them by twisting the tip. About half of the Mydata we rebuild have straight tubes but damaged springs. The new Mydata tools have

Hello, in my SMT process I have some problems with the solderability (look like dewetting) on a PCB with finish HASL Lead Free with a composition that is melt at 230 degree Celsius. My oven is with vapor phase and the peak temperature is 230 degre

I can't picture much of what you're saying, not for nothing, I'm just not connecting. During assembly, solder mask can affected by heat and chemicals. Typically this would be during: * Soldering * Cleaning I will tell you this: Not to defend assem

Ok lets put it this way. If the PCB house used a high quality mask and properly applied it to a properly cleaned surface and properly cured it, then as Dave stated above there are only two things that can destroy it. Excessive heat and overly aggress
