I agree with the loose parts but you can also put a O-scope where the encoder output goes into the computer to see if the signal has a lot of noise. A noisy signal can sometimes fool the input card into thinking the encoder pulses are ok.

We know from experiments that the structure of Sn can be manipulatedby means revese pulse-plating. This means alayer with less pits and thus a lower mminimum thickness is needed. www.ppcs.nu

I have the same problem but an MPM downstream of the Fuji. Im looking for schematics for this Fuji. Before we had another machine hooked to this Fuji and the output switch needed to be set to latch. Otherwise only a pulse was seen and it was not long

Hi, there are many type of lasers and each have its own applications. Have you tried the short pulse laser? I was told that it will have very minimal heat dissipated on the surface. On the other hand, there is also a water assisted laser where the wa

Differant machines have differant types of control. smoe use pulse motors with encoders and are controlled by PMD pulse motor drivers. Most of these will have parameters to determine things such as fast over shoot, speed for certian tools and varati

Scott, We have 2 Amistar Placepro 5620's and 2 5720's. One with a TF-14. I've personally been working on these for the past 10 years or so. Have a pretty good grasp of the process, if placepro's are what you are using. Glad to see Amistar is

UPDATE: Just for fun... I sacrificed a scrapped board to determine what remained and what fell and this is the result. Board dimension was 18"x9" and .9" thick. Components consist of hundreds of passives plus 386 proc (QFP256), TSOPs, SOLs 14/16/20,

A couple of questions for You. How old is this oven? Does it have a history of problems? When I have seen speed variations with our Omniflow 7s it is usualy the encoder but it usually spikes rather hard in one spot. You can see this physically and by
