We have had some components that popped off in our IR oven. It was attributed to the solder paste. The humidity was above 60% the temp was about 70 degrees.

Has there been a definite date for the total move over to lead free? Will it be 2004 or 2008. Also is there a direct replacement for leaded solder, I have read various articles on numerous alloys suggested for the switch, such as bismuth, tin, copper

Why would a board failure related problem be a process problem. I agree most companies believe EVERY problem is a Proces Problem, but in the real world we know this is not true. A pad lifting means your solder joint was able to rip it off the boa

Yes process engineers that work for contract manufacturers try to get the full CAD or XY rotation files from their clients unfortunately still many of their customers still give them only Gerber files for the PCB project. Unisoft has had a focus on

Belive it or not, these boards were run through a Centech batch mode Vapor Phase machine. Single stage top side IR preheat. Vapor temp 218 C. Solder paste is an SN62 RMA.The boards were FR4 8 layer w/ solder mask, fairly conventional as might be e

Truthfully, there are pro's and con's for both technologies. (put cost of ownership aside for one moment) Nitrogen won't dry humidified components as rapidly as a desiccant dry box. I'm talking about a self regenerating dry box that uses molecular s

Hello mickd, 1) The EL data & Vision_type is NOT necessary when using MCS30 for IP1 machine. note : your input of the above might have cause confusion during VP, hence the OS error. 2) I would suggest the following... 2a) lower the Lead_check_are

You are correct about the Manncorp machine, it was an MDC machine. The Essemtec machine is old(ish) but still runs fine, and last I knew they were still supporting it. My recent problem with Essemtec was in regards to software. I found a bug and sim

The point here is if you can't get the full CAD files or the XY rotation files and all you get his Gerbers and a BOM. Most all contract manufacturers and some OEM's at some time or another have to deal with Gerber only files. If you find yourself i
