Objective :To
design pcb layout
When
satisfied the circuit from the breadboard and transfer to the Printed Circuit Board (PCB). After cleaning, etching and drilling,
soldering process can be started solder the
electronic components one by one. Make sure all the components are soldered in
proper side. Ensure the component value and polarity is correctly soldered.
Those electronic components have polarity such as capacitor, diode, PIC, LM7805
and LED should be soldered in right polarity or it may cause the circuit board
fail to work. PCB is designed
for getting smaller circuit than use breadboard or strip board.
However, PCB
is often less expensive and more reliable than these alternatives, though they
require more layout effort and higher initial cost. PCB is much cheaper and
faster for high-volume production since production and soldering of PCB can be
done by automated equipment.
