Thanks for the advice, Steve. Hard-headed people in high-ranking positions spells trouble.

I would start by replacing the Z axis motor for head #4, you previously mentioned there was also a theta axis issue with head #4, you might be best served to replace both motors. These motors do go bad from time to time, We have 28 Juki machines wher

Qsoft will accept a negative theta on import and change it to a positive theta. For example cad data with a -90 theta will appear as 270 theta after import.

Our GSM1 with Flex2 heads started to generate occasional error message: "Axis head 1 theta positive lead error during move absolute command" and then stop. After palm-down it runs again for some time. Everything looks fine, so I have no idea where

MPM uses a one-print-Mylar system, as do other printer mfrs. In this system there is a Mylar sheet attached to a frame that is secured over the printer table with the board on it. You print onto the Mylar. The table X-Y-theta manual adjustments are u

Theta error came back again during our first production run. Swaped motcards as a final attempt to find an easy fix and nothing. I swapped heads with another MYDATA to positively isolate the problem. And the theta error followed the head.

I'm trying to visualize how that machine is laid out. Do they all rotate together, on a belt, so that there's only one sensor for the theta (R) home position?

Hi all, Am new to the SMT process. I'm in the process of purchasing a new SMT Pick & Place machine and am trying to figure out how to perform the buy-off. I'm from the semiconductor packaging background. For any new machine purchase, I'm used to se

How does a fiducial work? I am going to venture a guess as how it ralates to the parts you are trying to place... A PCB fiducial is a landmark. The fiducial tells the machine where the board is located in the machine. A single fid can only deter

1. Do you have the necessary equipment to take on such a task and 2. Why? My only guess is that you are looking to find the probability or likelihood of a particular observation and / or a "confidence" score on your other equipment. This is just a
