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

3. 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.

4. 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.

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

6. 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.

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

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

9. 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.
