SURFACE MOUNTING ASSEMBLY

• Surface-mount technology (SMT) is a method for constructing electronic circuits in which the components (SMC, or Surface Mounted Components) are mounted directly onto the surface of printed circuit boards (PCBs).

• Electronic devices so made are called surface-mount devices or SMDs

• Smaller components. Smallest is currently 0.5 x 0.25 mm. • Much higher number of components and many more connections

per component• Fewer holes need to be drilled through abrasive boards. • Simpler automated assembly.

SURFACE MOUNTING ASSEMBLY contd..

Small errors in component placement are corrected automatically (the surface tension of the molten solder pulls the component into alignment with the solder pads).

Components can be placed on both sides of the circuit board. Lower resistance and inductance at the connection (leading to better

performance for high frequency parts). Better mechanical performance under shake and vibration

conditions. SMT parts generally cost less than through-hole parts. Fewer unwanted RF signal effects in SMT parts when compared to

leaded parts, yielding better predictability of component

characteristics.

SURFACE MOUNTING ASSEMBLY contd..

• Faster assembly. Some placement machines are capable of placing more than 50,000 components per hour.

FINAL VIEW OF THE OUTPUT OF FUJI FLEXA AFTER PROGRAMMING

SETTING FIDUCIAL POINT (IT IS THE REFRENCE POINT FOR THE PCB BEFORE STARING THE MOUNTING OF COMPONENTS,THE LENSE OF THE THREE MACHINES READS THIS FIRST.IF THE REFRENCE POINT IS EXACTLY THE SAME AS GIVEN BY THE FUJI FLEXA THEN THE MOUNTING OR GLUE IS APPLLIED,OTHERWISE THE PCB IS REJECTED AND RED BUTTON STARTS GLOWING AND A SOUND IS GIVEN BY MACHINE SO AS IT SHOULD BE CORRECTED.
