44<p>Currently, photo-activated dry film is <em>the</em> technique for DIY PCB 
45manufacturing. There are plenty of tutorials available, but some info is a bit 
46hard to get.</p>
47<ul>
48<li>
49<p>First, the &quot;you can use a cloths iron&quot; line is a lie, repeated by people that 
50didn't try. Add a laminator to your toolset.</p>
51</li>
52<li>
53<p>Lamination is done between 104°C and 108°C.</p>
54</li>
55<li>
56<p>Exposition takes about 2 minutes on a 25W UV light, overexposition takes a 
57really long time (I could never reach it), so don't be afraid to double that 
58time.</p>
59</li>
60<li>
61<p>Revealing is done on a solution of 1g of Na2CO3 to 100ml of water. It is 
62really fast (1 minute or 2). Use a <em>very</em> soft brush to remove the film 
63residue (yes, you must remove it).</p>
