=20

	I regularly do quick test lashups using the breadboards, also using
PIC at 20mhz,
 but don't appear to have had any issues.=20
 I don't know how high a clock I would be comfortable lashing up on
these though,=20
 just as well I am a cheapskate when it comes to performance vs power
consumption,=20
 so I don't think i'll be going high Hz any time soon!=20

 Of course, since there are always incompetent people that blame
their tools
 instead of the real problem. Solderless breadboards can be quite
useful.
 Like any tool, they have their limitations, but those shouldn't be a
issue
 for most ordinary PIC circuits. Adjacent nodes will have some
capacitance
 between them, but so do parallel traces on a PC board. Most of the
times a
 few pF between nodes is expected and not a big deal for a well
designed
 circuit. If you have a very sensitive analog circuit where a pF or
two
 matters, then you should probably be using guard rings and the like
anyway.
 I've used these solderless breadboards many times, including for PIC
 circuits with 20MHz crystals. I don't remember any problems due to
the
 nature of the breadboards, although I thought about the
characteristics when
 building the circuits.
