Recently started setting up our GSM 4681A system, and one of the machines comes up with the message "WAITING FOR OUTPUT BOARD TRANSFER TO COMPLETE" after the Zeroing process has been started. Machine has all the defaults set, two SMEMA connected univ

I am a new employee at a company that has had a large turnover of employees over the past year. I am working on a board (components on one side only), the engineer (he is also new ) wants to use an .035 pad with a .021 dia. hole, there are no via's u

The majority of SMT resistors use the following notation. 10 X eg 153 represents 1k5 resistor The third digit in the sequence denotes the number of zeros to add after the first two digits giving the value in ohms. Many Caps will follow the same nota

without knowing your machine, I guess the axis does not find the zero pulse. You may have to re-place the incremental or linear encoder for the X-axis. Some vendors use proximity switches for a zero pulse which could be defective. If the axis stops i

Yeah, but the one's you're typing aren't displayed that way to me, anyway. They're all 00000000000000000000000000's. Hmmmm, let's see what happens when I post this: ° o O Those that I just typed all show up the way you apparently expect them to,

You will need to set the contact and squeegee zero calibration every time you set up a new product, we do this because the thickness of the substrate (pcb) can change between product and this will effect these calibration settings. The machine does n

In obtaining almost zero defect in solder wave. I would like to suggest the following: First,We must consider changing machine if it is more than 5 years old. second, use the right tools for the right job. Most of the traditional engineers will us

Another question about Set Command Variables. We use fixed dimension, multiple window PCBs in all of our UIC machines. It is often required that we use the rotary table to populate the entire panel, but this means that for each rotation, either the w
