I would evalauate: http://www.graphicode.com/GC-PowerPlace - Looks powerful, but also with a quite complex, confusing and messy interface. http://www.numericalinnovations.com/collections/fab-3000-gerber-cam. - Looks very promising, I found it quite n

Hi Spoilt...thanks for your reply. The latter part of your reply is a bit perplexing though. The CS-400E is easy to set up. There are two lights spots that indicate the insertion location. The component does not need to be prepped other than bent

We process an average of 300 units per batch with spikes to 750, we can sustain about two to three people populating to maintain good quality/throughput. Part placement is broken up equally to reduce operator stress(usually a limit of 5 different pa

Hi J_Dub, thanks for the continued info...Of course selective soldering would be very time consuming for such a through hole assembly...but 18 minutes, wow...didn't realize selective soldering could take that long. I would like to know the approxima

Operation Cost for SMT prototype line

Electronics Forum | Mon Nov 17 16:23:14 EST 2014 | budro

The company I work for is installing a SMT prototype line, and I've been asked to determine the cost of operation. I know there will be cost for solder, solder paste, flux, stencils, glue, nitrogen, ect... I just want to make sure I'm not missing any

Operation Cost for SMT prototype line

Feeders for your SMT machine. They can be a considerable expense, and you will hardly ever have enough if you have a high mix of products. You will wear out nozzles on the pick and place also. I don't see AOI in your machine list, so at least you wil

I can only say it looks okay for what you need, you will want a dual wave system it can make things so much easier. One thing to check would be the wave nozzle sizes I can see that the conveyor will do up to 15" but thats not to say the nozzle is

Is NO CLEAN any better for High Speed PCB's?

Electronics Forum | Thu Nov 20 17:46:48 EST 2014 | warwolf

If they asked you should try it? Im really interested in the outcome in general. We use no clean on 6 layer multi micro-BGA boards, chip size only goes as small as 0603 though. Around ~500 parts over a 4"x3" area. we haven't noticed any independe

Accounting for Dumped/Lost SMT Parts

Electronics Forum | Fri Nov 21 09:35:25 EST 2014 | gregcr

99% of the time the effort to try and track, count and update inventory takes more cost in labor than the parts are worth. We plan 2% scrap rate and move on with life. Simplifying the concept can actually save a lot of money in the long run. Can be

Accounting for Dumped/Lost SMT Parts

Electronics Forum | Tue Nov 25 12:37:26 EST 2014 | charliedci

We're attempting to seriously address this problem now. For us it is not the cost of the lost components as much as the loss of SMT efficiency holding a job waiting for a $5.00 reel of components and the cost of $20.00 to overnight ship. Our IT gro
