Reflow oven at 200 solder temperature looks good
Nice solder job with peak temp at 200, no noticeable scorching on the pcb. Oven must run a bit hot. Need a thermocouple to do some more testing.

How is ir heaters actually working?, they mostly only heat the material right?, not the air?, so you need to have an thermocouple attached to the pcb, or something?
Or paint the drawer black, and attach the tc on the drawer?
I was thinking a scrap of PCB
Yeah, but won’t you get strange fumes when the pcb starts to burn?
Well the goal is not to burn the PCB I guess ;)
I believe this is a very similar one: http://smart-prototyping.com/index.php?route=product/product&path=66_70_124&product_id=94 – for about $300 for the 110V version shipped “Express” to the USA – I bought the next size up for $400 shipped – I’ll check it out when it arrives.
A lamp based device like this heats things according to their emissivity. A black body with a low melting point and a low emissivity object on the same board would be the best test of if the reflow is okay.

As you can see if you were in vacuum you’d have a big problem, thankfully the air does heat up and help you do what you actually want. Still a nice black plastic header (often nylon) is a good object to put in for such a test in parallel with anything else.
