Good Idea. I just wanted the people to get the point. Any suggestions? I really want to start this forum. If we can track good and bad experiences it shows trends. See the thing is an OEM has to treat every license sale the same. For instance if they

I'm in a similar situation. We have a pre-historic semi-automatic printer that does a decent job, but would like to get an automatic printer. I've only just begun looking into the different options available, but would like one that could inspect t

Russ asks good questions and I think Chunks pretty much nailed it. Aspect ratio (aperture width/stencil thickness) s/b 1.2 minimum (I like 1.5 if I can get it). If your aperture width = lead width (.008"), yours is 1. Tough to get consistent paste r

I think Dave F. and Russ hit the nail on the head...components are wrong in the reel pocket from the get go. We would make a point to specify this when ordering parts. Russ also, has a good point with his number "2" item. If your machine is optomiz

Some have a bottom side adaptor plates with pins to make contact to certain areas of your board. The top side may have one or multiple heads that can move the entire area of your board. On each of these haeds is a pin like that from an ICT machine.

I think she might be more on track about the air flow. I would think they not only have thermal mass but also emit thermal energy well which would add to the dificutly of removing them. I think a Dpak would have more local thermal mass than the shie

CL pretty much hit the nail on the head. But also remember that solder paste will not go "bad" if not kept cool. It is not a fruit or perishable item (sorry guys, it's not). It's just metal and flux. The only reason they want you to keep it cool

I've used ECD's WaveRIDER and TIC's Wave Optimizer, and some people have sworn by Malcom's wave reader as well (if you look at all the past threads). We HAD an optimizer here in our shop, but somebody bwoke it. :-( As for evaluating these, see Chu

To do a profile at most companies, if you don't have a scrap board handy, you'll use the already-soldered board that's already been through ONE reflow cycle. You spend time attaching T/C's with the aluminum tape - after all, the prep-work is half th
