[sdiy] Cleaning PCBs in Ultrasonic Baths

[Richie Burnett]

I've got some Bluetooth modules here that also have warnings about U/S 
cleaning baths causing permanent damage.  Should be okay if you just U/S 
clean your SMD ICs before mounting any crystals and other sensitive parts. 
If in doubt I wouldn't drop it into the U/S cleaning bath though.  I 
witnessed someone dangle an expensive mechanical wrist-watch into the U/S 
cleaning bath at work to remove grime from the wrist band.  Needless to say 
it didn't work again when it was taken out!

-Richie,

You need to be careful with some parts in U/S cleaning baths.  Tuning fork
(32.768kHz) watch crystals are susceptible to damage from what I can
remember.  There may be other susceptible components too?

I’m pretty sure it is okay to do this, but just wanted to check with you
guys first, but is it okay to clean flux from PCBs after the SMD chips have
been soldered?

If so, what settings? About 65DegC? On the delicate setting for about 30
mins?

Many thanks in advance.
