MTM. Wow, people still do that huh? The problem I have with MTM, it assumes everyone performs things in robotic type motions. The best time study is one that relies on sound statistical methods, and across multiple operators. MTM, however, is gre

I am looking into purchasing a used TR5300 and was wondering if anyone with experience on this model could tell me if you have the capability of importing programs from the older TR3100 dos based programs into the TR5300 windows based interface witho

I am looking for some pads for a Universal VCD, PN 23502000. It is the pad that goes on top of the knurled nut that sets the anvil height (bottom of clinch base on the piston). Universal mfg machine is down so I'm looking for someone who might have

Thanks for the reply. We have software. It just won't connect when the Fuji controller (Flexa) is powered on. It appears that the controller ties up the GEM port. We were wondering if there is something that needs to be reconfigured or shutdown o

Matte solder mask greatly reduces the potential for solder balls, and since you altered the machine parameters with no improvement it might be flux related. Do you use a VOC free (water based) or alcohol based no-clean flux? Do you use machine settin

Mask finish is the #1 variable for micro-balling with wave and selective processes. The #2 variable is the Flux. There are some flux formulations out there who're known to have additives that virtually eliminate micro-balling. However, keep in min

Based on past, actual, hands-on experience, I have found that the PCB mask finish makes a HUGE difference in solder-balling. Glossy has different surface tension and peelback characteristics than matte finish (ie glossy sucks). http://circuitsassem

Yes, the previous "non-balling" flux was alcohol based, but very weak activity. We found it was worth the switch to water-based, to get prettier solder joints - but...at the expense of having to "brush off" solder balls on a couple of assemblies wit

Yes, the mask finish is prolly the #1 contributor to solder balling. Seen it many times. It's not that it's cured or not, went down that path about 3 or 4 times as well. Different fluxes can help too. But also check your preheat. If your are get

If the phone jacks have two conductors in them, I would wire them to standard SMEMA connectors so that the upstream side goes to the middle two SMEMA pins and downstream goes to the outermost two pins. If there are 4 conductors in the phone jacks, y
