Larry, What has been removed from the machine lately. Most bearings don't just fall apart while running without giving some type of warning. My experiance with LM bearings is they usually don't just fall out, most cases the bearing block was removed

Hi Ken Given the small mass of the dot I'm guessing that the adhesive is being flash cured by the heat of the board and the resulting semi-solid is unable to release from the nozzle like a liquid thereby causing your strings. Placing components on c

Okay, I believe that the XY table on our CP4-2 is not working correctly. When we place smaller parts (603,805,RNETS, etc...) they aren't seated in the paste all the way. Larger parts aren't a problem. They are kind of "floating" on top of the paste.

Sounds like you have a component problem! I say this because you say the sodler is flowing away from the components (leads I assume) This sounds like none wetting of the component. Do a solderability test on the parts. Take the parts and dip the lead

We have Siemens S-20 machine whose other gantry occasionally missmounts all its components in Y-direction(approx. 1/2 mm ). Most of the missmounts happens when there is a lot of 0603 or 0805s (B-side glue boards). Gantry picks up the components OK bu

Thanks folks. The current vendor is doing an alcohol wash, top and bottom, then performing an ionic test on 100 boards. I'm not to confident in the testing because the readings for a "clean" board are 25 ugm/sq in and a "dirty" board are 40 ugm/sq in

Hi Pat, is the soldering Ok when you solder them by hand ? We use some larger ferrite beads with no problems in reflow but I must say that we use a vapour phase and only max 5 parts/PCB. They do have a high thermal capacity and you use a lot of them,

I have two of the servo boards of the Fuji CP4-2 SMD3 version are mulfunctionaled. I don't know if it can be fixed or not. May be the moisture killed the board. A new one costs about USD 5,000 each. I wonder if anyone knows who or which company can
