a) Store in an area with high humidity?
b) Dunk in an earthed  water bath before fitting pcb?
c) Flood area with static dissipating air (deionisers?)

Note - if the charge is developed in the manufacturing process (ie an
electret material), the static may "recover" itself over a short period of
time. So use as soon as possible after "destatification". And ensure the
sensitive devices are protected againgst static problems once loaded on the
pcb. - fit high value bleed resistors on sensitive inputs etc.

Hi,
           I have the following problem. I have developed a dog feeder that
has
a PIC inside. A photo can be seen at

only
http://www.janso.com.ar/Picture%20010.jpg - Top view, full feeder
http://www.janso.com.ar/P000982.JPG - Full at the shop (400K image)

           As you can see the case is made with a process called
rotomoulding.
I don't know the specifics of the process and materials used but I can tell
you for sure that the cases come to the assembly area with lots of static
(i.e.. Plastics "stick" to them...)

           Now, the system has a RTC on it and a PIC (16C63B) the problem
I'm
having is that some RTCs (DS1307) are being damaged and I think is due to
static....

           What do you think I should do?
