The homebrewpcbs group did migrate from Yahoo! to groups.io; welcome. NaOH is not at all like bleach (NaOCl) - and I would not try anything that releases the Cl as a gas! It is very dangerous. There

So how it comes you can see on the video it strips all the copper from it?

NaOH and HCL is just going to make salt water and some heat.? It's not going to be an etchant.

Hi guys, I wonder if this is same as the yahoo groups that have been ported? Anyways, I'm new to the list, Hi! I watched the following video from

Thanks. It does indeed work, since I just put parts on a board using that same holder. A slight redesign would make the 3D printed arms a bit wider. The nuts are captive in the plastic. Harvey

Based on the Pace soldering stations we have at work, I will never by a Pace. The connector is very cheaply built and requires cleaning fairly regularly. Because of the construction, they are

Hi Harvey, ? I just checked out the images of the board holder. Looks pretty good. Thanks, Dave

One thing that sold me on the original Metcals was I could solder a wirewrap wire on a penny effortlessly even with a fine tip. Now I get tips for them that are not rohs temps. Rohs tips run hotter

Partially used?? I know the bottle of mine swelled up a bit.Sent from my T-Mobile 4G LTE Tablet

Yes, I noticed that too. Plastic will work so that is what I will use. I have to keep reminding myself I am a noob and don't have a lot if any boards to etch yet. I got my laminator modded and then

I may just keep my bottle of ferric chloride for a souvenir. For sure I am going with the HCI and peroxide for starters. I may as well make the cupric chloride for my first batch too. Thanks

Even if I don't try ferric chloride that was a good read. I have a few large sheets of copper for metal crafting that could use some patina. :) Thanks

Chinese tips? Never saw them. Amazon or Ebay? Ditto for the wands.... Harvey

Yep, 30 Volume peroxide is 9.09%. I just looked at my bottle and I actually have 40 Volume and that comes in at 12.12%. I found this online for the final word. :) Thanks, Dave
