We have a Speedline Electrovert Bravo 8 reflow oven. We have issues where we get a "thermal runaway HTSC trip" error and the oven shuts down. We normally can unplug and replug a connector into the Sensor/Relay Watlow AnaFaze TLM-8 module and it sta

Kelly, it's been a long while since I repaired a BRAVO. The machine was a little unique as far as Electrovert ovens go. I am pretty sure that it is the only Speedline model that integrated a PLC. Loved the OMNI's, not so much with the Bravos. I a

I'm going to guess that you've tried Speedline with no success. They're awfully annoying about their older machines. Things to check: - Thermistor for the zone working properly? - Opto for the zone working correctly? - Heaters working correctly? -

As you know there will be a lot of residues(such as rosin) left especialy on the peak zone and cooling zone of reflow oven after reflow soldering in a time. who use one kind of effective liquor or effective method to clean the residues ?

Out of curiosity, what is your top side peak temp @ reflow? Have you inspected the boards prior to SMT (at your 5DX machine?) Also, have you tried to run the board through reflow with out any parts or bga placed and inspected? I how long are you in

A couple of caveats; The FR4 will degrade with successive reflows and will eventually need to be replaced. Not a big deal for low volume, but something to be aware of. The bigger concern is that a sheet of .125" large enough to position your assembl

We started getting better reflow after rotating the pcb to locate the greater mass closer to the center of the oven. However we still leave space between panels on the conveyor to achieve a better reflow. This costs us production time. I'm simply lo

Can anyone tell me if there is an industry standard on how much of a space should be between PCB's in a convection reflow oven? Thanks

Just askin but why would someone even want to subject an assembly to even 6 reflow cycles? As far as how many cycles that an assembly can be subjected to, wouldn't that be determined my your components?

Hi, After reflow process we do Automatic inspection and after that direct to 5DX machine to check all the solder joints and we detected it at 5DX inspection. This card havent go to any testing.
