Well some of you are not seeing at all, at best you may be relying on someone's evaluation of a grey image from X-rays to determine whether your process is under control or not.

Let me tell you that a good majority of BGA joints that we see, using the Ersascope, you would not accept elsewhere within your process.

If you saw solder joints on gullwing devices that where dull or grainy you would modify your process until they became clean, bright and smooth.
