Subject: Amount of etchant needed

From: "Brad" <unclefalter@...>

Hi guys,

 

So, I think I may have found some much cheaper single side G10 boards in the color I want.  I ordered a bunch from here based on photos and the seller’s (slightly language inhibited) response on colour.  They described it as between green and brown, which seems like ‘natural’ to me.

On arrival, I was initially concerned it was just another shade of brown.  But looking around the very edges of the boards where there is no copper, it does indeed look green.  I’m assuming the copper on one side is sort of providing the illusion of a different color.

 

Anyway, my question here – I have to order etchant now (can’t find any sold around here) – if I have 5 boards of around 8”x9” to do.. how much etchant do I need?  Is the etching solution via ‘bath’ method pretty much one board per go?  Or can the same solution be used multiple times?
