I'm talking production quantities of stuff. No one wants to be
scraping tens of thousands of boards.
because no-clean flux
between D- and D+ on a USB line will cause it to malfunction. It's
on
the order of 100k ohms at that point even for short traces, which is
significant.
I've not noticed that one yet. I'll add it to the list for the CM.
OTOH I don't want to *have* to clean water-soluble off, esp under
chips.
No one does. All depends on your circuit. For example I did not care
at all about the flux or micro-Amps when I was doing 300 Amp 3-Phase
Drives.
