By Suresh Patel, Sales Engineer, Mer-Mar Electronics Silkscreen represents the outer layers of a PCB that include text-based readable information like component reference designator, test points, company logos, PCB part number and version number, etc. This is necessary for circuit board assembly, rework and debug support. The silkscreen ink is different from the regular printing…

The efficient laying out of traces on a PCB is a complex skill, and requires much patience. This task has been made vastly easier with the advent of readily available PCB layout software, but it is still challenging.Usually an electronics or electrical engineer designs the circuit, and a layout specialist designs the PCB. There are numerous techniques and standards used to design a PCB that is easy to manufacture and yet small and inexpensive.There are various types of software which are used for PCB designing, In PCB designing first think what is required, a Schematic diagram of the circuit then we have to make a layout by using software and this layout gets printed on the PCB after that Etching, drilling, component placement and soldering are done.
