Could I get some help please? I have a Heller 1700EXL, 7 zone oven and I'm trying to figure out a better way of off-loading my completed boards. What I have now is simply a small table at the exit of the oven with about an 8" drop from the top of

Elektrobit (JOT) makes a wave unloader you can use to put your board back onto an edge conveyor (if you are using just a belt on your oven now) and then place a FIFO or Mag Loader after that.

That gets me into the main operating system but most of the menue's prompt for another one. Also when you exit it asks for one to go to dos. ZCR does not work. Any help would be greatly appreciated.

we didnt see it as a potential risk, main accumilations we around the entry and exit curtains so we lived with it and cleaned (quick wipe with acetone) once a week.

We've been doing some testing. It seems that if you move the rail IN to achieve the correct width, the exit is maybe .125" wider than the entrance. If you move it OUT to achieve the width, the exit is .25" more narrow than the entrance. So I believ

I had the lurching issue...turned out I needed to readjust to cog wheels on the exit side of the oven. The cogs had slipped, and the chain was actually getting caught in the teeth...to the point that as the wheel turned, the chain would stay in it i

Thank you Clare. After doing some more research, I found they are known in the industry as "Carriers". I did look into that durostone material. They prices are beyond reasonable. My trek now is seeking a material to make planks out of to lay the b

Just wondering, what do companies who have a stand alone reflow oven use to allow their pcbs to safely exit off the reflow machine conveyor belt or pcb rails ? I've seen home made ramps that the pcb slides down.....but is there any other option ?

I have a Heller 1808 Reflow oven with the chain that has the edge hold to keep the boards off of the mesh belt. The feed end was more narrow than the exit end, and some boards would fall off. So we adjusted both ends to be the same. Well now, when

Are they getting stuck inside the oven or at the very end? If thermal expansion is the problem the boards would be getting stuck in the reflow zone since that would be the hottest and therefore the point where thermal expansion would be the greatest
