If you want to connect two pieces of PCB together, "golden finger" is commonly used. The gold finger interface is covered with red copper mats, which are also part of the PCB wiring. Usually when connected, the gold finger on one of the PCB is inserted into the appropriate slot on the other PCB (commonly referred to as the enlarged full slot).
Finally, the PCB on the board colors is generally green, brown, red, yellow and so on. These are resistive paint (solder mask) color. This color protects and insulates the copper wire. It prevents short-circuiting. Usually on the resistance layer it will also be a screen printing, it usually printed Characters and symbols which is white, it used for marking.
For a newly designed circuit board, there are always some difficulties in debugging, especially when the board is large and there are many components. However, if we master a set of reasonable debugging methods, debugging will achieve twice the result with half the effort.
For the new PCB board, we should take a look at whether there are any problems on the board, such as whether there are obvious cracks, short circuit, open circuit and so on. If it is necessary, you can check that if the resistance between the power supply and the ground wire is large enough.(custom pcb production)
