TLE 9 Printed Circuit Boards: GUESS WHAT?  OBJECTIVES: 1.Define what is Printed Circuit Board. 2.Identify composition of printed circuit board. 3.Differentiate SMT and THT. TLE 9 Printed Circuit Boards: GUESS WHAT?  PCBS (PRINTED CIRCUIT BOARDS) What is PCB? are the boards that are used as the base in most electronics the foundational building block of most modern electronic devices PCBs are most commonly made out of fiberglass, composite epoxy, or another composite material. TLE 9 Printed Circuit Boards: What is PCB? COMPOSITI ON OF A PCB Silkscreen Soldermask Copper Layer Pads/Vias Copper tracks/ traces Substrate TLE 9 Printed Circuit Boards: Composition of a PCB COMPOSITI ON OF A PCB Substrate made of fiberglass fiberglass is used since it provides a core strength to the PCB and helps resist breakage. PCB’s “skeleton” TLE 9 Printed Circuit Boards: Composition of a PCB COMPOSITI ON OF A PCB Copper Layer can either be copper foil or a full-on copper coating carry electrical Track/trace signals to and from the PCB PCB’s “nervous Pad/via system” TLE 9 Printed Circuit Boards: Composition of a PCB COMPOSITI ON OF A PCB Soldermask a layer of polymer that helps protect the copper so that it doesn’t short- circuit from coming into contact with the environment PCB’s “skin” TLE 9 Printed Circuit Boards: Composition of a PCB COMPOSITI ON OF A PCB Silkscreen how part numbers, logos, symbols switch settings, component and reference PCB’s “legend” TLE 9 Printed Circuit Boards: Composition of a PCB  SURFACE-MOUNT TECHNOLOGY AND THROUGH-HOLE TECHNOLOGY THROUGH- SURFACE- HOLE MOUNT TLE 9 Printed Circuit Boards: SMT and THT  SURFACE-MOUNT TECHNOLOGY Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device (SMD). TLE 9 Printed Circuit Boards: SMT and THT  THROUGH-HOLE TECHNOLOGY Through-hole-technology (THT) involves inserting leads of components into drilled holes in the PCB. Leads can then be soldered onto pads or lands on the solder side of the board, usually with a simple soldering iron by hand or wave soldering process. TLE 9 Printed Circuit Boards: SMT and THT  THROUGH-HOLE TECHNOLOGY Through-hole-technology (THT) involves inserting leads of components into drilled holes in the PCB. Leads can then be soldered onto pads or lands on the solder side of the board, usually with a simple soldering iron by hand or wave soldering process. TLE 9 Printed Circuit Boards: SMT and THT  QUESTIONS: 1.With the two different technologies used in Printed Circuit Boards, which do you think is the most reliable? THROUGH- SURFACE- HOLE MOUNT TLE 9 Printed Circuit Boards  SMT VS. THT Through-hole technology is very reliable as there is a stronger connection between the PCB and the components. This is why most of the manufactures still use through-hole technology. Surface-mounted components are much smaller in comparison to the through-hole components. This allows us to increase the TLE 9 overall density of the finished electronic Printed Circuit Boards  QUESTIONS: 2. What is the importance of PCB in our lives? Which field do you think benefited with the introduction of PCB? TLE 9 Printed Circuit Boards  Similar to how cities work, the components on PCB work together to form a complete system to power our devices. ASSESSMENT: https://forms.gle/ 9DmZo57A8P2oFfcKA ASSESSMENT: 1. It is a layer of polymer that helps protect the copper so that it doesn’t short-circuit from coming into contact with the environment. 2. A composition of PCB that is like your nervous system that carries signals between your brain and your muscles. 3. A technology that involves inserting leads of components into drilled holes in the PCB 4. A composition of PCB that provides a core strength and helps resist breakage. 5. It is the process by which components are mounted directly onto the surface of the PCB. THANK YOU FOR PARTICIPATING AND LISTENING!
