Jason, In Transmission AXI the entire solder joint volume is imaged, not just a slice (no missing information) as with Cross-Section. Also, there is no signal loss from mechanical or digital image reconstruction (highest contrast and edge strength).

You don't need to guess at belt speed, for example if your oven (heating area) is fifteen feet long, run at 1 ft./min that will be 15min total process time. As far as temp profiling you need to run T/C because each oven is different even if it is th

sounds like a profile for some type of adhesive. depending on your required profile (manufacturer supplied) make sure that it matches it. For most adhesives (loctite, etc...) you just have to make sure it reaches a certain temp (150C for example
