Does anyone know of a source for a reasonably priced and simple airflow measuring instrument? A simple mechanical anemometer with a pitot tube would suffice (I think...) in this application since I'm just trying to verify proper operation of the refl

If I read this correctly you have two identical ovens that were setup the same ie zone temps, fan speeds etc... when you ran the same board through each of them one showed a lower board temp. Is this correct? Is the temp of the board 7 deg. lower t

They may be misaligned so much so that self centering would not occur. How are you placing the micro BGA's? Depending on how the boards are transported onto the oven's conveyer, by the time they start to go through the oven, there could be additio

Too much Convection Airflow in the Reflow Oven blowing parts around ? Moisture Contaminated Parts out gassing ? Board out gassing? Just some thoughts, DG

Ditto on the profile/reflow oven...a couple years ago, we had a huge increase in the number of tombstones found post-reflow. Profiling the oven showed a decent curve with some innocuous minor deviations, and further investigation of the oven found 2

Hi, We solder a part almost identical to this without problems. Could it be your airflow in your oven is set to high? On our prototypes we didn't place any solder on the middle bad as it was not a connection, and we did not need it thermally, how

If you're going to vent through a single exhaust/fan combo, I would recommend spending the money, and getting an HVAC company in there to size the exhaust fan, and duct work. It'll pay dividends for you in the future. We did that at a previous comp

I don't know your oven but I have dealt with high temperature ovens/furnaces before. These would be my thoughts. Change in the resistivity of the heating element due to aging. Blockage of air flow in the oven by buildup of soot/ debris in either th
