Before sending some PCB to get pro made (really the best time proof solution) it is useful to debug it by etching it yourself

A Simple and costless method Flow to make proto PCB based upon Laser Printed Negative and Laminator or Ironer.

The laminator need a hack to increase heating temperature , but it's a more precise way ta make the transfer than ironer.

A method that uses CNC to engrave around paths to isolate them from rest of PCB board
