GROUND plane or nor GROUND plane

[Acetronics2]

Hi,

I ALWAYS use Ground planes ... reason is very simple :

it uses MUCH less perchlorate or persulfate for engraving ...

Surprised ???

Alain

and therefore [b]much[b/] more plating solution....

[Acetronics2]

And ... as plating thickness is much less than copper thickness ...

in the End ...

Alain

in the End ... depends on copper um/cost of etchant vs plating um/cost of solution

AND.... shelf lives of each solutions.....

It helped a lot Now I still don't know if my ground plane on the bottom side is fine or not (i removed the top layer ground plane). there's a program called EAGLE that creates the plane once you draw a polygon and name it like the ground on the board. Does it do it right or not? Hell if I know.

A snapshot of the boards (when there were still a ground plane on both layers)

By the way: I'm not using any RF device and my pic runs at 8MHz, 5V.

looking good.. well done
turn off all the layers that you do not need to see and just leave bottom layer, then use the address label to "SHOW" your signal (whatever you have called it) and see the signal track it will shine brightly as a highlight, you will then see if the ground plane is cohesive. Its all down to wether when you created the polygon you used the setting "orphans", difficult for me to see in the jpg at the moment(on a mini machine) wether this is the case.

You are better not to have orphans using a single ground plane , unless you are running out of ethcant

cadsoft.de have a dedicated newsgroup, there is a lot there and they are very helpfull

If you have 1 layer board then you dont put Ground Plane on the other side.

If you want fast etching then use as much as possible Ground Plane.

If you want to protect against EMI then use as much as possible Ground Plane.

If you have double sided PCB, then
       If you want all the above then
            use as much as possible Ground Plane.
       Endif
Endif

If you have RF then use as much as possible as much (again) Ground Plane 

If you have double sided PCB, then
       If you want all the above then
            use as much as possible Ground Plane and
            connect with vias as many times as possible.
       Endif
Endif

Conclusion:

Always use as much as possible Ground Plane!
