The tapping noise is what you hear when Hydra taps each tool on the tool bank to make sure the tips are seated well. The error is a Z-motor problem. The gear is at the top of the Hydra and needs grease. Have you cleaned the old grease and applied new

I admit, 16 mil QFP printing is very challenging but if all your control factors (print speed, etc...) are setup correctly (through DOE) extremely high yields can be achieved and more importantly a repeatable and robust product will be manufactured.

It has been our experience that the problem you have discribed was not solder process related. We had two such instances in the past and both were component related. The first case involved a PLCC28 that failed test. Reflowing the solder seemed to co

Dave: You pose a very good question. We have been in the electronics x-ray inspection business for 18-1/2 years and, to date, we have not received a single report of damage associated with x-ray exposure. However... we do see signs of long term x-ra

Hi Jeff Actually it's not necessarily Signal to Noise Ratio or even RF circuitry. All no cleans leave behind residue by description. This residue can affect RF or other high frequency circuits in a number of different ways including SNR. Very high

Hi all We have an Omniflo 5 (-97 vintage) with pin chain conveyor. Lately the chain drive motor has started to emit some chirping noises, as if there were a bearing running dry or something. Is there some kind of maintenance schedule specified for t

We are currently having problems with our SPM AV Screen printer. It is an intermitant problem, sometimes it will make a loud noise as the stencil is going down on top of the board and sometimes it does not meet its destination. Sometimes the machi
