We had a supplier that put a [fuzzy and of variable height) line of ss between all chip R and C pads. Of course we were in low cost mode and had purchased a year's worth of boards.

But that's how Purchasing is supposed to work, right? Then boast how they saved 50 bucks that day on buying slightly plemmed boards. Then you spend thousands of dollars over the course of the year reworking thru the plems. All the while management

Not to mention the couple hunnert they save by NOT getting an air ride truck to ship a new inline printer. You'd be amazed at what an E5 can do to a pallet in 3000 miles. I can't believe the thing worked.

Try using a solder like S03X7C from Koki, which uses cobalt to prolong the tip life & also a wire wool type dry wipe instead of a wet sponge.

Unless you go custom, the only automation I've seen for tape is the automatic dispensers. They work very well and do reduce time needed to perform this process. Could help until you revamp your process like Davef has posted.

I've spent quite some time on the google search, I keep hearing rumors but have not yet found anything. Thanks for the feedback. greg

way too low of yield. with that technology on the board I would expect about 98% as well. So what are the defects? and more importantly, is your design, machine(s) and/or process(s) capable of this technology? Details I am sure are forthcoming R

As a sidenote, if nothing of the above works, IPC 610 states that it is accetable (class 1,2,3) for solder to touch a SOT body if it is plastic.

true in the olden days, new osp's have excellent thermal stability. they are thinned or removed by organic acids mainly. contrary to believe due to the higher tin content they do tend to work well with lead free better than leaded used to. cheers gre

i have 1 customer using our reflow oven, he is facing the problem that after taking the boards from reflow oven ICs & some resistors felt down.they are using our glue dispenser also, the glue is not fixed with the component. wht will be the solution
