Greg, You guys are right, it was a thermistor. I believe the machine was powered up with the wrong voltage. Here is what gets damaged if the transformer is tapped for 230 and you apply 480: 1. Both CPU modules on the MX100 PLC's blown. 2. Both col

Without the proper tools in house you will not be able to determine anything but the most obvious problems. At minimum, some side looking microscope that would allow visual inspection of a row or two, and to be able to rule out bridging. Using that

You have a rather old machine that you are running....now realizing this you need to check some things. 1. Clean the scales in the x and y direction. On some of the encoders there is an led to see if its reading correctly....Usually it turns green b

Hi, I am evaluating equipment for a new SMT line that I will run myself as a side business. I have so far settled on Assembleon as the machines are available and I have heard good things about them. Your comment gives me pause. Is it really such a b

HI, The short answer is, "whichever machine finds your defects." I would suggest evaluating machines based on a common vehicle. Make a bad board and identify the defects. Make a good board and have your vendor teach and tune the machine to the goo

PROBLEM SOLVED :) ! I messed with parameters, then started to check hardware again. and.... There are 2 transport position on the carrier 1) vacuum 2) mech clamp Both have fiber position sensor which shows the status When there is component, the

When an assemblied board was on active service, what's the main reason for its failure:the package broken; the mechanics fatigue failure under thermal cycle; the corrosion caused by salt and vapor; the broken chip inside the package etc. I think all

Hi! Some varibles that I would think increase the risk: -The use of Nitrogen when soldering. -The use of IR may cause thermal vias (if placed only on one "side") to produce uneven heat distribution and thus wick the comp. -Uneven heat distribution.
