Homebrew PCBs

I'm having issues understanding as well.

But I find using laminated dry film photoresist to be a very easy process for home use.  The only hard part is finding a place to get the dry film material in small quantities.

I've been buying it from a guy on EBay.  I use a simple laminator and simple chemicals available at the grocery store (washing soda) for processing.  You can make your own UV exposure unit if you want, or pick one up for under $100 on EBay.

It is much easier and has much better results then any other process I've used (except mechanical etching.)
