Cheery disposition??? Would a few ;-) ;-) ;-) help? [Oh and look who is talking, the one planning the Mickie D gig after the traces on the this board start vaporizing with the fuseable link schtik.] Are you sure you're getting flux all the way up

Our R&D Guys used to push the lead of a fine pitch component using a Pick or a thin metal tip and if the lead snapped off from the land it's considered failed. Is that the proper way of identifying the solder joint strength? We got problems with sold

A worthy endeavor. Consider checking the fine SMTnet Archives. Searching on df* lists almost 200 postings between the "Design" and "Production" Forums. Further, check the SMTnet Newsletter. Earl Moon wrote some very good articles on DFx. The art

I wonder what kind of equipment the board designer had in mind? Are you shure you can do the board with a Mydata ? Where do you put the tray for your 20 mil QFP's? 10 mm thick plus component height also appears to be a problem. Multitroniks can do la

first try to get rid of the problem instead of cleaning. Try Almit V16L for finepitch (good experience!) no, I do not work for that company... assuming that the rest of your process is perfect and you do not use old paste, do not use the same paste o

We have customers that are requiring no flux residue left on boards after soldering of non-water washable parts. We currently use Multicore Crystal 502 No-Clean to solder parts that are not washable. Has anyone come up with a good way to remove this

The quip; All you can get! By the way, worthy answers above, especially Dave F getting a little tied up is good to see, he's always on the money otherwise. But seriously, watch for damage to other components. Example; thru hole's such as radial c
