Trust me Peter, I've put my time in with the EM! I'll be a happy camper when they'll set up the search to include/exclude by location. It's less a matter of knowing what's out there and more about knowing what will suit all of our needs best.

I'm having a difficult time understanding the need anymore for a West Coast show going forward. Other than tradition, let's face it.....there is much more going on in the midwest these days. All and all....I don't see much of a future in Southern C

Bert, Sounds like the CPU in your IP 1 needs replaced. I have seen the exact same issue a few times over the years. Only fix I came up with was replacing the CPU. Contact me if you would like to buy a functional used replacement. Thanks, Jared

There are several smd components in our factory that don't reliably wet to solder during reflow. Paste and placement are good, but the component won't wet reliably. All of the other components on the boards solder fine, but one of these components

thanks I haven't the same shift in all the components, that's why I need to correct them one by one and this takes a lot of time. I am searching in the Software of the machine if there is any way to change just one parameter to correct all the data

Had the very same thing happen the first time we used the small QFNs. The aperture for the thermal pad in the center needs to be cut in a grid form, either squares (with around a 10 mil spacing between openings) or circles, like a BGA pattern. Too mu

If the attack was unwarranted I apologize. I still stick to my answer. Unless the board shop can get rid of it you have to find a way to deal with it. Etching trace paths into the stencils is inexpensive and works just fine. If you do not have the ti

1. Can X-Ray Inspection System damage the EPROM OR OTP during inspection after Reflow? 2. At 300 degree Centigrade, program in the EPROM OR OTP disturb. Is that true? 3. Sometimes, if some ICs couldn�t program first time then I put that IC in oven

Hi all,, I running SMQ230 solder paste with a time above = 40sec with peak temperature = 239 degrees .. the complete reflow takes almost 6 min with a slope (150to190) close to .60 degrees/sec .. may I have some concern about that or it's ok?? tks..

Fellas: I'm having a tough time with voiding with my lead free water soluble paste under my large BGAs. I know some is almost inevitable, but this is more than I'd like. This is with a slope of .9, soak of 60 seconds, above 217 for 85 seco
