Does this mean that the Etching is my problem? what i did was i filled a tupperware container with boiling water. then i took a smaller tupperware container with the etchant and PCB, and put it in the boiling hot water. after about 15 minutes, i replaced the water with fresh boiling water. then i took the PCB out after 35 minutes.

when i took the PCB out of the etchant, and rinsed it off, i inspected it CAREFULLY with a 16X magnification jewelers magnifying glass. all of the toner was still on the board. it was very dark, and i only saw a few VERY small pinholes that were caused in the ironing process. how could the etchant make many more pin holes buried under the toner?
