To mount the electronic circuit we do on a plate PCB. To make a PCB board should follow the following steps:
A) measure the length between the legs of the components that come into play in the circuit.
B) carried out a design on graph paper tracks the face of real size, which corresponds, of course, with the circuit diagram.
C) The design is passed onion.
D) Cut a copper plate for printed circuit to the appropriate size for the previous design.
E) design is pasted paper cut onion in printed circuit board.
F) sites are marked in the legs with a nail and a hammer. There has to be hit very hard, just dial.
G) design is drawn again but now in the printed circuit board with a permanent marker. It usually works very well Edding model 30000.
H) A solution of 1 / 3 of hydrochloric acid solutions, 1 / 3 of hydrogen peroxide of 110 volumes 1 / 3 of water. This solution is a highly corrosive acid, therefore we must take extra security measures: use of special gloves, tweezers, fan.
I) is introduced in the acid plate. All the acid corrodes and gets into water.
K) will be removed indelible paint with a cloth soaked in acetone.
L) minitaladradora was drilled with a 1mm drill holes design.
M) Solder the components in their respective locations, should be borne in mind that the design shown is the face of slopes (see below). Welding is performed with tin and tin solder.
