Do you have a bake oven that will reach 200C? You could bring a batch of boards up to temp and then start the pluckin'. A sfar as the solder goes if you apply flux to the leads they remove very clean as far as solder goes. To remove the flux we pl

Hi, This would be a very exciting idea. Nitrogen is an inert gas, so this is why it's used, however Hydrogen mixed with oxygen in normal air is highly explosive, so it would be one of the worst gasses to use in a reflow oven I would think. Remember

Nonductile fracture!!! Sounds peculiar. In that case, stop wasting you time messing with the thermal recipe. Either your: * Components have poor solderability [test this by dipping the leads of a couple of the SSOP in your solder pot and then asse

Hi, It's removed from the fridge, and the tube is loaded into the stencil printer, however it's winter here right now, so it's still quite cold. It's Australia, so when I say cold, that's relative, however the room can be about 10 dec C in the morni

The directive is called RoHS. Meaning that is not only the lead that is the issue. The materials need to whithstand a hihger temperature, not only delta T is an issue (but huge). Moisture sensitive devices: how to handle these? You will see an increa

Doug, It always seems easier to fix one or two problems by eye at the time. The real problem comes when the customer wants the same board run again later. You're okay if you saved the corrected placement routine, but if you end up moving the job t
