Thanks Josh, But I have a question: How about when we are talking double sided PCBA:s? The designer/layouter will see the PCBA straight trough and the mirror flip will cause the "shape" to be 180 degree Horizontally. Now that is not a real problem, a

In the next couple of weeks I will be attempting to place 0402's and 0603's using a Quad QSA-30. I am a little nervous as I have heard along the grapevine that the machine struggles in placing the smaller components as they float around in the pocke

Hopefully you dont have a lot of 0402 placements. You must have 'quality' feeder/feeders for the 0402 parts. You then should limit the picking to 1 head for those parts. Do this by assigning only 1 xf nozzle in your program. oh....Straight z-rods wi

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

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
