As stated above, Hydrogen is EXPLOSIVE, very bad idea. Management might have meant HELIUM, also inert.

Let's not be hasty about the BTU, the Pyramax consums even more N2 than the Paragon that it replaced by something like another 40%! and the Electrovert aint that much better although it's been a while since I looked at them.

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

call me picky but doesn't hydrogen combust? maybe soemthing you could do is look at your process and your products and decide if you actually need to run in N2. Yes ok I can hear the crys now but seriously, for the vast majority of things if you have

Can anybody suggest how can I achieve good solderability in convectional reflow oven If I reduced Convection Air Speed 80%. The whole purpose is to reduce 0402 LED tilting in the convectional reflow and the PCB having QFN with 60 to 120 sec soak, 30

What is the year, make and model of your oven? Are you running it with Upstream and Downstream (pre-reflow, post-reflow) conveyors? Is the qty of the product low, medium or high? What is the max process width of the oven? what is the max board with o

As you know there will be a lot of residues(such as rosin) left especialy on the peak zone and cooling zone of reflow oven after reflow soldering in a time. who use one kind of effective liquor or effective method to clean the residues ?

In our reflow oven it has pins which move at the predetermined speed to move the pcb through the various zones in the oven. The forward row of pins is fixed along the front of the oven. The rear set of pins is adjustable per the width of the pcb. We

We started getting better reflow after rotating the pcb to locate the greater mass closer to the center of the oven. However we still leave space between panels on the conveyor to achieve a better reflow. This costs us production time. I'm simply lo

A couple of caveats; The FR4 will degrade with successive reflows and will eventually need to be replaced. Not a big deal for low volume, but something to be aware of. The bigger concern is that a sheet of .125" large enough to position your assembl
