In my opinion save the old block and see how hard is to replace one if you have problems in future. I suppose it will be fixable.

Do you mean in a reflow oven or wave solder? if so check your exhaust blower, make sure its still drawing. if not the flux/dust that builds up on the exhaust pipes may be falling into the machine.

So how'd you do it? Each machine has a separate hole? Or all piped to one?

I agree with ProcEng1 that using a capped PVC pipe filled with flux is a good way to keep flux stones from drying out while in storage

I checked the spec sheet and it gives pressure and no volume. The volume on one of my older Yamaha's was about 2.7 CFM. That corresponds roughly to the volume of a small 2HP compressor at your local hardware store. You can place on of these in a smal

You may also consider different sizes of, off the shelf, Dry Box. i.e Seika McDray (http://www.seikausa.com/)as an alternative to N2. It is mobile, no N2 hard piping, less operating expence and actually can remove moisture while storing. good luck!

Does anybody know a (if possible low-cost) system which can travel with the PWBs through a reflov oven (like some temperature profile loggers) for measuring the residual oxygen? My problem is, it is a batch oven which does not allow to have any pi

Tks BT Can't be many places tougher than automotive, 'cept maybe oil field, down pipe. We use Dexter Hysol flow underfills for both 1 thou and 3 thou gaps, but they wouldn't come close to filling under a BGA. Most BGA are sitting about 16+ thou fr

No. Since most glues don't don't give-up many solids, we're [at least I am] speculating that you are using the same oven for both reflow and glue cure and that the 'slime oozin' out from your TV set' [FZ 'Overnight Sensation']. Ooops, no the slime
