4. Finally, installation of the amp components onto the PCB stands for both
drilling mount points and also soldering them with the soldering iron and
drilling machine. The drilling machines designed specifically for this purpose
are used to mount the components and the drilling process should be
meticulously implemented by taking into consideration the marked areas.
5. What about the soldering process? Soldering is a process in which two or
more components are joined together by melting on the PCBs.The tip of the
soldering iron heats the copper pad and the lead from the electric component
and the through-hole components with leads or wires are carefully placed
onto the PCB and are later soldered to the back side of the board.

A) The leaded amp components are inserted into holes drilled in PCB
and soldered to pads on the opposite side by soldering iron.
B) To create an amp, we need a wide variety of components such as
capacitor, resistor, TDA 2004 amp, input/output channels, cooler,
pod, diode, plastic box.
C) This method utilizes the process of removing the unnecessary
copper on sheets specifically designed for amplifiers.
D) It is an electronical device and boosts the voltage, current or power
of signal.
E) The circuit board is covered by a paper with circuit diagram and
later pressed to the copper plate.
