Sr. Tech, youre absolutely correct that the X-Wagon (pancake) motor is the one which will do final positioning when moving to a programmed position. The X Axis motor in back of the machine is used for rapid traverse of the axis. I was thinking more

Hi John Yes I am still having the same problems years later! It keeps Fred in work supplying me with replacement tips too! Mydata came up with a supposed fix to alter a parameter called prepick which puts a pause in I think allowing the head to st

Well yesterday was uncharacteristically warm for a British summer! I always have the panel off the end of the machine at all times and certainly used to have a large desk fan blowing into it - for some reason I stopped. I had a run of strikes yeste

In general terms, guidelines for moisture sensitive devices (MSDs) say that you shouldn't put a component through reflow after it has reached its exposure limit with respect to moisture absorption. When using an automated hot air rework tool to remo

Hello all, We are using z1850/60 machines. The APC test is damaging a 1.8V device on the board. The APC stimulates -/+3Vdc in fast mode. I understand the dangers of over-voltage. But what I need to know is how the part is being damaged when the ent

Has anybody else had issues with shipping circuit boards in static shield bubble bags? It appears that parts are getting ripped off during shipping. I suspect that they're getting caught in the bubbles when the boards shift in the bags as the boxes

Thoughts are: * Most board fabs have routers that can do this work. Can yours rework these boards? * Scrap the boards and start anew. Someone made a mistake. Cut your losses. * As a wild and crazy guy alternative, buy a router with a 45* bit from

We have run Mydata machines for 10+ years with no ESD damage from the machine itself that we know of. Can you tell us how you have verified it is the machine causing the ESD damage? It seems to me the ESD damage would be far more likely coming from
