Creating the board involved multiple steps including printing inside and borders with different mills. Putting the mill needed extra caution specially when the origin of the cutting needed to be determined. However the process afterwards was automated. I used 4 double sided tape to secure the board, and it worked relatively well
Next step was soldering the electronics. I started with the ATtiny part as it was in the center of the board. After anchoring one of the legs, I soldered all of them and resoldered the anchored leg. Adding other pieces was a similar procedure. Note that the initial amount of solder for anchoring was critical in getting a good solder, as too much solder could cause bending of the parts during soldering.
