QuoteMost of the boards I work with are pretty bomb proof, not laptops though haha :-/
No electronic boards are immune from ESD ;)


Think about that the next time you get in a lift then Mr TheBoy  ;)
Noooo! Don't say that! ;D

Muahahahaha! ;)

::)

Seriously though, I've seen boards stacked then carried and generally roughly handled...they can take it ;)

They might at first....but time will tell.

Seriously, ESD is a big issue, even more so in the modern world of sub micron silicon (almost everywhere now).

In our factories, its a big deal with antistatic floors, footwear and heal straps (wrist straps are rarely used in a production environment) and ESd can build up with just the movement of an arm (hence touching a case before hand its no guarantee...)

The big issue is that ESD can often do un-seen damage which can ause problems later.....like damaging the aparsitic diodes on the IC's I/O, memory is very prone to such damage

It costs big bucks to impliment and follow and buisnesses dont spend money unless they have to...

That is the big problemt with ESD - people change stuff without protection, and because it works afterwards, think that its OK.  Its not, and damage would have been done - often resulting in differcult to find intermittent problems.

Also, "it's ok, I held by edge of board" type comments aren't valid either.

PWB? same as PCB? Last time i worked for a computer manufacturer (along time ago) they were designing PCB's upto 14 layers thick......wonders how many layers you can get to now?  :-/
