Step-by-step summary to form the double-sided board thus far:
Materials needed:
3-FR4 Copper Clad Laminate PCB Printed Circuit Board Material;
4-Iron;
5-Pencil;
10- Hammer;
11-Miter Connection;
14-No Drain Fridge Pot w/ water;
16- Steel Wool;
17–3000 Variable Speed Rotary Tool;
18- 3 x Sewing needles;
19- Blocks for woodcut printing;
20-Absorbent paper;
21- Scholar Ruler;
22- Permanent Markers, Fine Point, Black;
23- PERCLORETO DE FERRO EM PÓ 500G;

Let’s go to design flaws:
#01 — the ideal would be to iron the two faces simultaneously (Council of Pompermaier); all I should have done is mark the three holes, sit the paper on top and bottom matched in the holes and perform the transfer; that’s not how I did it :/the next one certainly:)
#02 — the front and back holes did not match. I had to remove the front rings to avoid short-circuiting.
#03— I’ll have to find a much finer drill, maybe 0.8 mm, and do not hit a nail on the board too hard; notice the internal bubbles and some trails lifted … just hit the nail on one side and very carefully to mark the drill’s hole;
#04 — soldering the 555 will be a problem: I have two tracks on component’s side; I’ll have to use a very thin piece of wire and put this track in contact with the 555’s pins. I Have to review the board to overcome this issue!
#05 — my solder is with resin core (metal and flux — volatile and activators) and made it very difficult to solder because the iron’s temperature had to go to 400 º Centigrade; Because the core is oval the solder does not get the ideal temperature, it’s a pain in the ass“/ I’m going to change my solder and use 60% tin and 40% lead and see if it works better…
All in all, this is my first-time PCB making…learning by doing is my mission!
That’s all for now, folks!
Till the next episode of DIY with Eagle o/
Bye!
