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

Avillaro, I don't have hands on experience with Vapor Phase equipment, but my guess is that it will work better for thick boards like yours. Trying another chemistry is a logical move. May be it is worth trying the fixture for connector flatness as n

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

Just a note, on fixed galden machines yes the way they compensate for rise time is as the previous post suggested, change power and also stage the lowering of the PCB into the vapor cushion ie not the main one but further up in the tank. The disadvan

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

I have been using Vapor Phase for about 5 years. We just started building our first BGA and the reflow profile is the same as most SMT assembly.We build PWA that are 25 layers thick with 0.050 heat sinks. We have done some preliminary X ray and BG

We are evaluating Vapor Phase right now, and there is something that bothers me a bit. The machine has a preheating stage where we can bring the board, components and paste up to temp to dry the paste out before descending into the Vapor. The heatin

Hi, When I started out and we were the same we got an old MYDATA TP9-2U. It places everything, and you should be able to get a cheap one second hand, that will perform very well. They have vision as well, as an options, and that works very well. I w

A huge help in the very first statement, Josh. And yes, fixed vapor mass in the machine I am currently evaluating. OK, and a machine that can change the vapor volume based on a calculation of mass of the assembly sounds logical. (whirrrr,click... a

I worked for a medical instrument manufacturer a few years ago and we had to calibrate all measurement devices. That included everything from our vapor phase oven's thermocouples to 6 inch steel rulers. I don't see any logical justification if you'
