Manufacturers of "Benchtop" Vapor Phase Reflow Systems | 10 November, 2004

Hi Folks, Does anyone out there know the names of the manufacturers of batch style vapor phase reflow systems. I'm not interested in anything in-line. I'm looking for relatively small footprint systems. I've come across Wenesco and Sintronex. Does anyone know of any others?

Thanks, Justin

EPM-IBL of Germany is distributed in the USA by AICT Technologies hailing out of FLA. Ask for Eric Forg at 407-831-2550. They Sell Vapor Phase ovens that range from bench-top to in-line systems and everything in between.

The producers of fluids can probably help. Try: * 3M * Dupont * Ausimont * F2

Let us know what you learn.

I used ASSCON VP450 with Galden 205 Fluid. It worked fine. Good Solder Joint Quality. I'm not promoting the product just sharing what I had.

You can make one out of a stainless steel tank pretty easy. Cost maybe $1000.00. You will need some hot plate type heaters and some copper tubing with a water flow source to keep the vapor down in the tank. We used two fluid types so one blanketed the other. The chemicals are expensive though, I would use Galden. I started my company using a "homemade" one and it worked just fine for us for years. It is slow though. Ours held maybe a 5 by 10 panel and you had to "dip" and reflow one at a time.

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 the fluid come to the boil should keep your temp ramp under control.

We used a pasta cooker with a glass lid so we could see reflow. We used a small hot-plate under to boil the fluid, and then the board was placed on an egg ring on the inner container. You know those pasta cookers that have a second inside pot with holes that the pasta sits on. Thole holes allow the vapor in to the board. You can see the vapor cloud travel up the side of the pot.

However in this example, you need to start with a cool pot, or the vapor cloud will not have anything to allow it to grow slowly, and the cool sides of the pot keep it under control. After reflow, wait for your pastes specified reflow time, and then gently move the pot into a cold batch of water to let it cool down, and to condense the vapor cloud.

This works for prototypes, but we moved away from this now, as on the small 0603 and 0402 components we just could not keep the tombstones down, and it's really hard. But great quality joints, and if I was starting again from nothing as a hobbiest, I would use it again.

Regards,

Grant
