Hi, Yes, all you really need to do is boil the fluid while suspending the PCB above the vapor, so it's quite easy. However I would recommend against dropping the board direct into the vapor cloud, as that would be a very fast warm up, while letting

I assume you using a fixed mass vapour phase system? Yes rates of rise are impacted by the mass of the PCB, larger the mass to mass of vapour phase the lower the rise generally. So if you load the machine with very little mass PCB rise times can be

We are looking at getting a new inline SMT reflow oven and I have been shown a new vapour phase oven made by ASSCON. It looks very good - just want to know if any one has used one before and can comment. Thanks

If the sensor can survive the 200C in the molding machine, then could it not survive Pb-free soldering? Maybe not convection reflow, but it should be able to survive vapor-phase reflow. I would control solder height by controlling the amount of paste

I am wondering if the fumes from reflow oven should be filtered in any way or can be just releaed to the atmosphere? Could not find any info about it. We're using Indium 8.9 HF SAC305 paste.

I know Mydata has machines that have a 44" X 32" placement area, reflowing something that big is another story. Most reflow ovens I know of have a maximum conveyor width of 20", although Heller ovens can go 23.5" wide. If you're into Vapor Phase sold

They all are inlineish They just carry the board to the vapor chamber. in a reflow system all the boards in the oven from beginning to end are in state of process, which gives you more speed. If the board has a long cycle time VP is not a problem. If

Just few brand names of VP reflow machines: - ASSCOM http://www.asscom.de - epmIBL http://www.epm.ch One of the the Heat Transfer Fluid used with today Vapor Phase Reflow(condensation) technology is the GALDEN that you can select according to

Rehm Thermal Systems (Germany)offer in process vacuum reflow in convection ovens and vapor phase pending what makes sense - volumes of PCB per hour needed. There are other vendors getting into this of course. Can only get single digit void free join

Never mind I reread your question and realized my mistake. Your best bet is just to either get more labor to rework and up your output that way or to make a custom machine that has the hot air nozzles fixtured and timed. Then load up multiple boards
