I built myself a reflow oven using an off the shelf 29l fan forced oven with digital controls. I then fully insulated the cavity around it with kiln fibreglass, and added a metal infill at the back as the back of the oven was just a metal sheet. Anyw

Not sure it's always a great route as the smaller ovens are going to struggle to get a perfect profile for a consistent result, especially on bigger boards with higher layer counts and mixed technology. You may want to take a quick look at a batch va

I have used the Chinese ovens that Manncorp is selling bought from another supplier and they can do the job. These will do the job. You can manufacture metal piece(plate) slightly tilted to collect the boards behind the oven(similar to wave soldering

I measured the temperature rise when I built the unit and it has a nice linear rise in temperature over the 3 minutes. I have used the Quikees before. The galcon gas stinks and must be evacuated. The galcon is expensive. The galcon is a perflourocar

Hello, sir. We are a SMT equipment manufacturer from China. We have a hot-press soldering machine that can change your current situation of manual soldering on PCB board. In addition, we have a better reflow oven, the upper and lower two cold tempe

Hello lads. I run a Sequencer 2596 and have had good luck. Just recently it sounds like air is not making it into the machine. With the machine palmed down it has the required 55-60psi going in, when I release the Estop the psi drops to about 30 and

I am having an issue with aligning vision for solder paste inspection with the PCB in the Momentum machine. The SMT operators setup the profile on the machine, which I then import into Aegis CircuitCAM to add PCB locations. But when I export again, t
