Make their own circuit boards, see circuit schematics, the circuit will be painted directly on the CCL, but this is the positive and negative side of how to solve ah?
General method is:1. First draw the position of the component on the paper (the element has size), and then draw the pin position (such as the foot of the integrated block, the capacitance, the resistance, and the foot of the two or three pole tube);2, copper foil location diagram;3. Deal with the oxidation layer of copper clad laminate;3. Carbon paper to carbon copper by carbon paper;
To Handmade double-sided copper clad laminate, PCB must be used for software production, not to hand CCL, can only use the method of printing printed laminates.
Since it is hand painted, and their own production, there is a point, it is impossible to double clad copper, can only be covered with single-sided copper (double-sided manual process can not reach).
