I hadn't heard of using a domestic oven like this. It sounds like an

wouldn't think many would like being heated his hot.

The commercial assembly lines I've seen use robot soldering irons
instead of heating the entire board.


I ahve never heard of a line usiung robot soldering irons!! It would be
far too slow. Lines normally use either wave soldering or IR reflow.

Jeff,

You'd be surprised how quickly a robot soldering iron makes a connection
- less than 1/2 second per connection (and, of course, you can have
multiple irons working on the same board simultaneously, with proper
programming). The first time I saw it was back in the 70's, but I'm
sure it was in use long before that.

Yes, it's slower than wave or IR reflow. But it's a proven technology
which has been around for decades and does have its uses - i.e.
temperature-sensitive components which can't handle the heat of wave or
IR reflow.
