Re: IRON METHOD for PCB's
Hi Les. Not tried your "touch up" method..... I use nail varnish...... its surprising how well it flows, when stored in the fridge..... at room temp its sludgy and slow. Up to now I have not mentioned the "occasional" missing bits.... in my case usually at ends or corners... even though I pay good attention to these areas. My etchant is ferric chloride,,, I still have some left after my years in industry. I was very fortunate to obtain an etch tank as sold by Maplins, a few years back...... I worked in returns at the time..it came back in pieces ....so I bought the bits and made a jig... and rebuilt using the silicon adhesive used in the aquatic world. A heating element and air blower finish the setup...takes about 10 mins usually, but some heavier coppers obviously take longer.
