The whole question arose when a member posted that this is off topic, 
and I agreed.

Solder paste dispenser mechanical design is not even close.  
Mechanical etching is a legitimate and viable method of MAKING 
boards.   Yes the list owner will allow it, but that does not mean 
the responses will be the best for the person wanting to build the 
unit.

How about we agree that neither you nor I post on the solder paste or 
pic-and-place designs as we can see how the other members would 
answer this topic ?  (for a week or so ? )

I imagine it will get near zero play on this list.

Yes, you  are interested, and I am intereted, but this is not the 
mechanical design list for this topic.  Neither by the depth of 
member knoledge and experiance, nor the stated purpose of this list.

It IS a topic that would have dozens and dozens of professional 
responses on both your list and CCED.  Probably even have sites to 
people who have done it and personal experiances from those who 
already worked out the bugs.

I would make a screw plunger, that would need to be incremented as 
paste was diplaced from the syringe.  the A axis location would need 
to be advanced incrementally.  The next logical step is software and 
the next after that is troublshooting.  I think you mentioned a 
solenoid or compressed air ?  Neither of us have taken it to the 
final stage and worked out the bugs.

To keep it on here will eventally become a dis-service to the person 
making the unit.

And that, my friend, is why there are so many lists, and why both you 
and Steve have a couple dozen lists between you !

I think we are wearing this debate a little thin, so I'll let you 
have the last word.

self moderation is turned *ON*
