Working Paste Before Printing

Electronics Forum | Wed Mar 20 11:55:19 EST 2002 | slthomas

Interesting. Ours failed miserably. Of course we toss everything on the stencil at the end of a shift (they are instructed to let it run down to minimal volume on the stencil as they approach quitting time) so it's not an issue. We are more concer

If you are going to wavesolder the board after SMT you will have to epoxy the parts on instead of paste/reflow. I used to work for a company that squeeged it on. You will have to research component layout guidelines if you do want to wavesolder. If

Universal instruments registration

Electronics Forum | Sat Apr 20 01:25:39 EDT 2002 | lysik

It is not just the rgistration fee. It is the fact that often after you register the machine you sre still denied a certian portion of service. UIC is very in check with their registration pricing. OEM's do however have a clause that says we can not

QP-132E // FCM 2

Electronics Forum | Sat Apr 20 22:50:36 EDT 2002 | lysik

I am sure the QP-132 is a more stable platform. It is a Fuki after all. My big question is why not X2 CP-6 machines. I mean you can tell by resale value of the FCM Vs the QP-132 that the QP-132 is a rock solid machine but, for such cheap money two CP

Immersion Ag

Electronics Forum | Mon May 13 16:20:10 EDT 2002 | ian

Are you refering to MacDermid Sterling Silver finish or immersion silver in general. We have had enquiries about Sterling Silver from a customer and the blurb I have read looks very good (don't most sales literature). Has anyone tried this finish? O

Inventory control of SMT parts

Electronics Forum | Thu May 09 12:29:59 EDT 2002 | dougt

So after barcoding takes place, is this info sent to the feeder or the outside world (is the feeder just a number that the pick and place machine looks for or does the feeder tell the machine what it has)? I guess if every machine and remote feeder f
