WHAT IS THE DIFFERENCE BETWEEN SMT AND SMD

SMT stands for Surface Mount Technology, the entire technology of mounting and soldering surface mount components onto a printed circuit board or PCB. SMD is an abbreviation for surface mount devices, the both are different.   Surface Mount Technology, Firstly, a PCB stencil is aligned on the surface of the boards and solder paste is applied using a squeegee to ensure the pads are coated with a uniform and controlled amount of solder paste.   Secondly, via a pick and place machine or hand placement, the components are mounted onto the boards in their respective locations. The wet solder paste [...]

FR4 Material for Fabrication of Printed Circuit Boards

FR4 is a glass epoxy laminate sheet that is most commonly used in PCBs Fabrication (Printed Circuit Boards). It is used in all kinds of flexible printed circuit boards, and other semi-rigid PCB variants. It displays excellent properties of high strength and flame resistance among others. The ease of integration in applications and allowance of component mounting has made it a preferred material in most PCBs.   Production Process of FR4 Fiberglass sheets are impregnated with epoxy resin. These sheets are used to construct FR4. Eight of these reinforced sheets are covered with a copper foil layer. This entire construction [...]
