SEMINAR ON SURFACE MOUNT TECHNOLOGY By- MARODE DNYANESHWAR D. B.E.(E&C)

OUTLINE Surface Mount Technology Role of SMT Benefits Surface Mount Devices Advantages Challenges

Surface Mount Technology SMT is a Technology that uses surface mount devices, which are often leadless and require small space. Allows high-speed component mounting and reduces PCB size. Supports Advance consumer products ( LCD color TV, video cameras & so on). Has the great advantage in portable stereos, CD players.

ROLE OF SMT IN ELECTRONIC WORLD Play a predominant role to increase area efficiency & the corresponding to the system volume. Electrical and Mechanical features are only achievable with SMT. Small light weight portable components are mount only by using SMT. SMT entails making reliable interconnections on the board at great speed, in the smallest possible area.

BENEFITS OF SMT Reduction in package size. Reduction in weight of product. Noise Reduction. Higher operating speed due to shorter interconnections.

COMPONENT PLACEMENT SMD’s on both sides. SMD’s on one side & discrete components on other sides. Randomly distributed on either sides. The comparison between wireless local area network and the diagram of internet connetion using wireless local area network.

Processes used for placement of components Screen Printing Method. Glue Method.

SCREEN PRINTING METHOD Paste Application on PCB by SCREEN PRINTING Pick & Place of components by HP-180 & SP-120 Visual Inspection Manually Reflow Process

GLUE METHOD Glue Application on PCB by HS-180 Pick & place of components by HP-180 & SP-120. Visual Inspection Manually. Reflow Process to cure Glue. Wave Soldering Process.

MACHINES USED SP 120 Manufactured by Siemens It is multi headed machine Placement speed is 7200 components/ hour Easy to used Window based Software

HS 180 Manufactured by Siemens It is single headed machine Placement speed is 4200 components/hour

CHALLENGS Need latest Technology Requires well trained worker Complications
