We got a F04 error (internal Memory fault) on the shared drive and entered 8 in location N001 as per the maint manual and cycled the power. I then set all the locations listed in the manual to thier default settings. Now the motors do not run to thei

From my understanding: Sigma is the same as one standard deviation. So 3 sigma is the same as 3 standard deviations. It all boils down to how repeatable your machine is. Another way to look at it is the probability (or confidence) that the machin

Morning all, just took a look at a new board we just got in and the there are different pad areas under the same BGA. What happened is engineering uses wider trace sizes for some pads and those overlap when more than one go to the same pad. This caus

Josh: You're correct it's tough to describe the layout of the BGA pads and traces. We wouldn't be too excited about seeing this board either. On one hand, for the obvious lack of care taken in doing the layout, this is a junk board and you shouldn

kenscj: Responding to your points of interest: * On the smoothness of BGA solder balls causing solder ball misalign, void, solder short after reflow: We expect the solder balls to be smooth and have no sharp irregularities. We can't recall attribut

Hi, That's expensive, and perhaps the MYDATA answer is not that far off if you get one of the TP9 models, which can be picked up for $40K or so. They use the modern feeders, and place only 1 component at a time, so will do ok on prototypes. As it's

Hi, Sorry, should have been more specific. We're looking for one of those benchtop/very small footprint machines to go with a support rail hand printer & benchtop reflow for our design lab to use for low volume prototypes. Something you can plug i

Hi Dave... Kanban (variances JIT, Lean, etc.) is a system I'm familiar with and have seen it used with great success in a fairly large company that was very well organized, well staffed, and spacious enough to identify things visually across the roo

Good Morning Everyone, We have had an issue with a specific board house on a job that has bright tin plating. At one point, a lot recieved proved to be unsolderable. The plating looked OK but no wetting would occur at reflow. We hagled with the boar

Chris, From your email I am assuming you are using an immersion tin process. Is that correct? If so, I would highly recommend you talk to your board house about the amount of tin that is being deposited on your boards. If the tin deposit becomes ver
