Subject: [Homebrew_PCBs] ant-farm etching tank

From: "Andrew Mathison" <andrewdavid.mathison@...>

Dear Paul Mateer

I share an A3 sized vertical tank for over 20 years with a friend, we do not use it that often nowadays sadly!

But I can say that a horizontal tank will only be OK for single sided boards. Double sided need a vertical tank with plently of bubbles of air to keep the etchant working on both sides at the same rate.

I have never done it, but I would imagine it difficult to keep both sides etching at the same rate.....

regards

Andy

I would think a horizontal tank would be better than a vertical one.
