How to solder ground?

[Buehgemeiste]

Hi,
just for fun i have soldered some active crossovers on perf-board.
they get a little bit better each time i do that, but i am far away from what i want.
my very latest project is a subsonic filter that features three opamps and virtual ground design.
the opamps have to be connected with + and - from the power supply and i have seven spots, which should be connected with virtual ground.

what is the best way to solder such 'ground points'?

i would like to have wires on the backside of the board, because i have trimpots on the front and i would like to change the opamps for listening tests.
on my last boards such points always became ugly hills of solder.
are there any good examples how to avoid that?

There is no need to have just one "giant" ground solder blob.

Stretch a piece of TCW (tinned copper wire or a cut resistor lead) between two points about 20mm apart (or whatever) which need to be grounded. This on the back of the board maybe 5mm from the copper tracks.

Solder all your "ground" connections to this. No two in the same place as it is then difficult to modify.

The impedance will be close to zero as far as audio is concerned.

Ok, i'll try that.

Are there any pics of such a solution?

i did it like this and it works.
