I only build my own products, so it has to meet my needs for QA only. I am doing some 20 mil lead pitch (0.5mm) and will soon be doing a 0.4 mm pitch part. I have more magnification on my microscopes (40X) but almost never need to go that high. If

Hi, We need to solder a USB plug onto a PCB in our SMT machines, and this is the same type of plug you see on USB storage devices. It's a very flat connector with 4 SMT pins, however the hard part is the bottom of the connectors is the same level

We are in North Western U.S. I like 2.6 better (for our mix of builds, anyway). 1.0 works great on PTF parts such as fine pitch QFP's but I don't like it for chips. It's too picky and we wind up forcing parts to the 4.0. We have another GSM dual

SWAG is right on the money. I had a 0.5 mil per pixel camera and a 1 mil per pixel camera. As you increase magnification your focal range goes down. So your part height becomes much more critical. Parts out of focus will be rejected to the dump b

The APE machines are still OK in their place. We still have two APE machines that are over 8 years old and still are good for some processes, but have been consigned to the leaded solder rework area. We have upgraded to AirVac since the advent of le

We've got an auto fuse clip (a pair of tin/nickle spade type receptacles joined with a nylon bridge piece) giving us fits. The pins on this thing have a right angle profile (symmetrical "L" shape) and make great flux traps. No amount of tweaking pre

In addition to the pre-emptive steps mentioned above, in my experience there are certain BGA package designs that seem more prone to that corner bridging. I have seen some packages that will essentially "curl" down at one corner as the package begin

I have developed an application to help the ease of image set backups for YesTech AOI systems. I'm sure many CM's like to keep their scanned image sets for future reference, and manually moving those files over and over wastes time, and increases th

For those of you who recently downloaded CircuitSmart, I had placed the wrong setup.exe in the download file. It was an error on my part. Running the bad one would have brought you back to the browser to show you what looked like an XML configuration

Calculate numbers according to your situation, as follows: Cost = Cost per kilowatt hour x [Amps x volts x hours of operation � 1000] Cost per kilowatt hour: What we need to do to figure out the total cost is get out our electric bill. Look on the
