Hi Stephen, Heller ovens go up to a 30" wide apperture, I would give them a shout. Marc. -----Original Message----- From: Stephen R.

Well, it seems another "opportunity" has presented itself to me. Looking to assemble a 24" X 24", 52-layer board... piece-o-cake, right? Not real sure of all the components that are on it yet, but I do know that there is some 20-mil pitch stuff... I've been asked to investigate what it would take equipment-wise, and dollar-wise for us to do this. Printing, I know of Surface Mount Techniques that have large board printing capability. Pick and place, I know that Mydata can place monsters such as these... Reflow has me a bit stumped...I've heard that Heller ovens have throats big enough to swallow something like this, but when I checked some spec's on their web page, they say their oven can handle 23.5" boards. I also looked into Vapor phase reflow units, and R & D Technical Services (formerly Centech) has a unit called a RD3 that has 24" X 24" process chambers...thinking about it, vapor phase may be the way to go with this beast...it's around .390" thick! I've got a Electrovert MCS-1000 batch cleaner, so it'll be able to clean this thing... won't need wave solder, so that's one blessing... Just asking if there's any other vendors of equipment that can handle boards this size other than the ones I've listed. Sure would like to find some used stuff because the equipment that we get would only be used on this beast. The quantities aren't going to be that high at all...
