My first question is how many failures have you seen due to hair length I will bet zero. So upsetting your employees for something that will not reduce your failure rate by one board is pointless. However someone mentioned hair in the process that i

Hello all, Just a quick intro as I am new to this group... My name is Phil, and I work for a small electronics company in the Channel Islands. We make boards for many companies. I am the Mirtec MV-3L user, and I am intrigued by this thread. Our MV-

EricR: Regarding "*** By the way, since we have used the Tin-Silver-Copper lead free solder there has been a strange liquid type chemical leek from the oven exhausted pipes." ... I don't know anything about your process, but the first thing I'd inve

Juggalo, Your boss obviously hasn't thought about the implications of taking a complacent attitude toward safety can cost. He is liable if someone gets hurt working in his plant who isn't wearing the proper safety equipment or none at all. It does

Glad to hear we have more Jade users on the forum! What kind of flux footprint is your fluxer leaving on the board? You called it a "spray" fluxer.. We use the MIC fluxer that functions like a jet fluxer. Do you flux each individual lead or do a

Thanks for the help. Ramp soak spike but due to the density of this assembly it's more like ramp spike. Yes, leaded. I'm getting similar results with or without the carrier. (I designed the carrier like swiss cheese, full of holes and scallops on

If the machine is printing with an offset on all products, then yes the printer needs to be calibrated with the fixture. That particular model requires the same tools as the 500 and 1500. They were different from other MPM machines of that or prior

We have had some success in void reduction with LGA by pre-tinning or "bumping" the devices before placement. The extra solder seems to allow a slightly higher standoff, and allows better outgassing, is my guess. A lot more labor , but the results

Hello, I am a student and i am having problems with understanding a certain pcb design. You can find the pcb here: http://pdf1.alldatasheet.com/datasheet-pdf/view/449682/TI1/LMR62014.html What i don't understand is if the pcb is just routed normall

You want your machine to spot the fiducials automatically. A 40mil round copper pad is the absolute minimum fiducial to use, but we found in practice that our Quad equipment won't spot them reliably. I am now using a 60mil round fiducial and it picks
