If it's forced air convection I'd check all the circulating fans and filters. Also if its a clam shell bonnet make sure it's closed all the way and the seal is good. You didn't specify whether it is one zone or the full length of the oven, I do not w

We are seeing this the full length of the oven. We run a lot of double sided boards, so we cannot run them on the wire mesh. I checked inside the oven to ensure there was no build up of dropped parts that could block it. The temperature difference

Hi! I have been studying the reflow process. And now, I am researching for a recommended reflow oven that can process a small to low-medium production SMT soldering. For the experts in the reflow field, please recommend a reliable reflow oven. Here

Place a Digital CRO on that 24V rail. Watch the output. trigger on voltage drop lets say 18V picking a figure out of the air. You may well have another rail in your supply or nearby pulling your 240V //110V rail. Most likely a shot Electro either on

There is a small cylindrical sensor on the air cylinder that that actuates the chuck. I can't remember if there are one or two. Its (they) are about 4mm x 20mm and I think (it) they have a signal light. Make sure it is mechanically working properl

We use the PDR machine. Great bit of kit. We prefer it due to the IR heating on the top. No air is used to potentially blow neighbouring components that go into secondery reflow off the board. We have a Zevac to but thats not as good. Camera is

The best test will be to X-ray BGA under 3-D X-ray. About the techniques used for BGA repair you can probably take closer look to some BGA repair stations, even though I have seen it done with hot air gun in the early days.

We are high mix - high changeover aerospace manufacturer. We have 3 1809 MK3 air ovens. There has been absolutely no issues with them. We have 4 MPM Momentums. I looked at DEK but felt the MPM's were put together better. They are very easy to use
