Hey Logan, This is an excellent resourse and should have pretty much everything you need. http://www.national.com/packaging/parts/MDIP.html#8 You get a list of a lot of different components and their pictures. You can view their dimensions and look

Dear Steve. We are EMS company and we are getting wide range of components from our customers. Some of them came in trays, that can withstand up to 75 degree maximum. If someone will not pay attention to this the tray get damaged (if there is some Q

You could have said "why don't you just flop 'em over twice into the right tray?" lol. Yeah, that's the right way. I was kind of focused on what I had to do here to get two different parts from full trays into two cut-in-half-the-long-way trays sinc

My recommendation is that you send all your question to Mumtaz Y. Bora, Sr. Staff Component Engineer from Kyocera Wireless (mbora@kyocera-wireless.com). She is also a member of the committee that is writing the new specifications for Moisture Sensit

Innovative Drying Co., considered this possibility early in our experiments. The rate of chamber pump-down is not a consideration. However, the selection of the vacuum pump is critical. Avoid oil-sealed pumps at all costs. A poorly maintained oil-tra

I would love to see the documentation of the experiment that indicated that a 24-hour/70 degree C bakeiing cycle at 10Pa is more effetive than a 24-hour 125 deg C baking cycle at normal atmosphere. We have looked at the old Levey-Perlmann paper and f

Fowler: Thank you for your documentation. Your finding roughly coincide with our own. We also found that 70 degree baking removes 50%/60% of the ingested moisture from moisture conditioned MSD packages We ran an additional experiment that compared

Good to know there are a few smart people left in this industry like Darby. I love how everyone assumes the original poster was only talking solder paste. We use screen printers for five different materials. Some of which we triple print by design

Many years ago, we used to double print. The way we did it was with a rubber squeegee set to do a flood stroke, followed by a return cleaning stroke with a metal squeegee. Why?! Well, this was in the days before Laser etch, and because the chem bat

Wow, Chunks, condescension becomes you. Not. I think that in this forum when someone mentions *stencil* printing and doesn't specify what material, we tend to gravitate towards a scenario that involves printing solder paste first, then adhesive. If
