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

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

Well, I don't know if you want to muck around this much, but I bought a GE (Chinese made, of course) toaster oven with convection fan. Nice big glass door in front, you can use it in bake, broil, toast or convection oven mode. The only thing missin

I looked at a number of small bench-top batch ovens and saw two things. First, they got VERY expensive when you got above the very smallest units. Mine will fit an 8 x 12" board. I still have to do one that size and see how uniform the temperature

Process, process, process. We have been doing BGA's, uBGA's, LCC's etc for over 10 years. We have no X-ray and we don't even have a real rework station. In 2005 we placed just under 100,000 BGA's we reworked less than 100, we scrapped less than 30. W

Hello. We have currently a big problem with our Reflow owens getting very dirty very fast. It's like a thick layer of "dust" on all parts in the preheat and the beginning of the cooling zoon. We dont have that all the time and it's seems to be from b

Lead Free is probably worse as it contains something like 25% more flux by volume than Leaded. But is unusual as No Clean organics usually volatise off and rosins are non volatile so should not accumulate readily unless mixing with other gases in the

We have an Advantis and it's great for low volume, high mix (flexjet head). If you have good CAD data to upload, it takes little time to program as you can update vision on parts and placements while you are actually building boards ("NPI mode"). I

I must ask the silly question- are you sure you deposited the correct amount of paste? Depending on aperature design-the voiding could come from a stencil that has its holes partially built up with old paste. If paste volume is guaranteed, then what

SN100C contains no phosphorus. It has a dross rate equal or lower than tin-lead solder, where as SAC drosses at 2 to 3 times the dross rate of tin-lead solder. Addition of solder dross inhibitors, such as phosphorus, can be effective inhibitors of
