I've never seen them used or even heard of them being used like this but you might want to look at http://www.sipad.com/ You will still have to work out other issues like how to keep the SMT on while you wave the LEDs. Maybe you can get these board

Hi we are currently experiencing a problem with solder contamination of the gold contact pads on our pcbs following the reflow process, possibly through sputtering. We have been advise that this can be caused due to the pcbs being humid or due to th

We are having problem to develop lead-free (SAC305) reflow profile for big SMT electrolytic caps. The delta T of the joint of the cap with the rest of the board is too big to fit in the tighter lead-free window. Any suggestions regarding the total pr

How big is the cap ? We successfully reflow caps that measure aprrox .750" x 750" at the base and are .678" tall. The ovens we use are Vitronics XPM's.(1230,1040 and 930) We also process these caps through our Omniflow 10. As stated, oven length wi

I am doing some research on flux free/flux less SMT reflow soldering. Do you have any equipent/process recommendations? Does anybody use it for volume production and what are the constraints (finish, balls, paste, vacuum, pressure, size)? What is

We recently purchased an IBL VPP-M600 vapour phase reflow oven. We currently only have partial documentation and need to know the requirements for the water cooling. ie flow rate, cooling power etc. We also need the spare parts listing and service ma

I talked to someone regarding the Biral oil and they said that they have had a problem with it "jelling up" when exposed to oxegen. Has this been a problem for you as well? I ordered some Stabylyn 773ND from Vitronics. I hope this stuff works for 57.

Rather than go into detail here, try googling "classic reflow profiling". One of the guys at ECD (a thermal profiler manufacturer) wrote a pretty decent article that covers most if not all of it. You DO have a profiler, don't you, or an oven with
Reflow ovens for automated SMT PCB assembly, specializing in lead free processing and nitrogen reflow. The best convection reflow ovens on the market.
