5. 1. Single-Sided PCB 5 Types of PCB 2025 A single-sided PCB is the most common type of printed circuit board. It has a single conductive copper layer above the substrate. The electrical components are soldered or placed on one side of the board, and the entire etched circuit is visible on the other. Since these boards only have one conducting layer, the conductive paths cannot intersect or overlap and hence take up a lot of space.

6. USES: 6 presentation title 20XX Single-sided printed circuit boards (PCBs) are used for basic and low-cost electrical/electronic instruments such as calculators, power supplies, LED lighting boards, FM radios, timing circuits, and so on.

7. Advantages of single-sided pcb 1 Cost-effective 2 Easy to manufacture 3 Suitable for low-density designs 4 Easy to repair if in case something goes wrong 5 Easy to design

8. 2. DOUBLE-Sided PCB 8 Types of PCB 2025 A single-sided PCB is the most common type of printed circuit board. It has a single conductive copper layer above the substrate. The electrical components are soldered or placed on one side of the board, and the entire etched circuit is visible on the other. Since these boards only have one conducting layer, the conductive paths cannot intersect or overlap and hence take up a lot of space.

9. USES: 9 presentation title 20XX Double-sided PCBs are used in a variety of applications such as cell phone systems, power monitoring, test equipment, amplifiers, HVAC application, UPS system, and many more.

10. Advantages of DOUBLE-sided pcb 1 Reduced size which makes circuit compact 2 Relatively lower cost 3 More flexible 4 Increased circuit density 5 Suitable for advanced electronic systems

11. 3. Multi-Layer PCB 11 Types of PCB 2025 Multilayer PCBs have more than two copper layers. In general, any board featuring at least three conductive layers is included in this category. Multilayer PCBs are designed in a ‘sandwich’ fashion, with several double-sided conductive layers divided by an equal number of insulating material sheets. All of these must be bonded and laminated together under high pressures and temperatures to ensure that no air gaps exist and that the final PCB assembly is properly stable.

12. USES: 12 presentation title 20XX Multi-layer PCBs are used in computers, laptops, mobile phones, tablets, medical equipment, GPS trackers, and many other more complex circuits and devices.

13. Advantages of MULTI-LAYER pcb 1 Compact in size 2 More robust 3 High level of design flexibility 4 Suitable for high-speed circuits

14. 4. Rigid PCB 14 Types of PCB 2025 a rigid PCB is a circuit board that cannot be twisted or folded. The board’s base material is a rigid substrate, which gives the board rigidity and strength. They are composed of multiple layers including a substrate layer, a copper layer, a solder mask layer, and a silk screen layer which are adhered together with adhesive and heat.

15. USES: 15 presentation title 20XX Rigid PCBs are used in GPS equipment, computer, laptops, tablets, mobile phones, X-rays, heart monitors, CAT scans, MRI systems, temperature sensors, control tower instrumentation, etc.

17. 5. Flex PCB 17 Types of PCB 2025 A flexible printed circuit board is made up of many printed circuits and components that are arranged on a flexible substrate. These printed circuit boards are made using the same components as rigid printed circuit boards. The main distinction is that the board is designed to flex to the desired form throughout the application. These PCBs are available in single-sided, double-sided, and multilayer configurations. This contributes to a reduction in the complexity of the unit assembly.

18. USES: 18 presentation title 20XX Flex PCBs are used in organic light emitting diode (OLED) fabrication, LCD fabrication, flex solar cell, automotive industries, cellular telephones, cameras, and complex electronics products such as laptop computers.

20. 6. Rigid-Flex PCB 20 Types of PCB 2025 A Rigid-Flex PCB is a hybrid circuit board that combines elements from both flexible and rigid circuit boards, resulting in a board that can be folded or continuously flexed and is typically shaped into a flexed shape or curve during the manufacturing process.

21. USES: 21 presentation title 20XX Rigid-flex boards can be designed in a compact manner, and their lightweight nature makes them an excellent option for a wide range of applications in the aerospace, medical, and consumer electronics fields.

23. INTRODUCTION 23 2024 PCB is an acronym for Printed Circuit Board is used to connect the electronics components with each other using pads and tracks incorporated on a laminated copper sheet . PCB always serves as the backbone of every electronics circuits. composition OF PCB Now let's have a look at the composition of the PCB board. A simple PCB board is composed of different layers that are joined together with the help of heat and adhesive, giving the board a compact shape into a single object.

24. These PCB board layers are named: 24 PCB COMPOSITION 2025 Substrate Layer 2. Copper Layer 3. Solder Mask Layer 4. SilkScreen Layer

25. SUBSTRATE LAYER 25 PCB COMPOSITION 2025 The base material, also known as substrate, is composed of fiber glass. The FR4 is the most common fiber glass used today. It is like a solid core that provides rigidity and thickness to the PCB board. Some PCB boards are composed of phenolics and epoxies which are not as durable as FR4 but they are less expensive and come with a unique bad smell. Low-end consumer electronics mostly use these types of substrates. The nature of the substrate material defines whether the board will be a Flexible PCB or a Rigid PCB .

26. COPPER LAYER 26 PCB COMPOSITION 2025 Besides the substrate, there exists a thin layer of copper foil. Heat and adhesive are used to laminate the copper foil on the board. Commonly, both sides of the substrate are laminated with copper especially in double-sided PCB , except in cheap electronics where only one side of the board is laminated with copper.

27. Solder Mask Layer 27 PCB COMPOSITION 2025 Above the copper layer foil, there lies a solder mask layer. This layer is applied on the copper layer to insulate the copper layer from surroundings, in order to avoid conduction, if direct contact happens with some metal or conductive material. The most commonly used solder mask comes in green color, however, it's available in other colors as well.

28. Silkscreen Layer 28 PCB COMPOSITION 2025 Above the solder mask layer, there exists a silkscreen layer that allows the user to add symbols and number for better understanding of the board. Silkscreen labels provide the clear indication of function of each pin and component soldered in the board. Silkscreen mostly comes in white color but there are also other colors available including red, grey, black, yellow etc.

29. INTRODUCTION 29 2024 PCB is an acronym for Printed Circuit Board is used to connect the electronics components with each other using pads and tracks incorporated on a laminated copper sheet . PCB always serves as the backbone of every electronics circuits. PCB MOUNTING Characteristics

30. Through Hole Technology 30 PCB MOUNTING CHARACTERISTICS 2025 Through-hole technology is used in simple PCBs normally single-sided PCB and double-sided PCB. In Through-hole technology , electronic components are mounted on the PCB board with leads inserted through holes. These leads are then soldered on the other side of the board and the ends are trimmed off.

31. SURFACE MOUNT Technology ( smt ) 31 PCB MOUNTING CHARACTERISTICS 2025 In surface mount technology, SMD electronic components are used, which are quite small in size and instead of leads, these components have small pads, which are soldered into the PCB surface. Surface mount components are 10 times smaller than through-hole components, making them an ideal choice for complex and advanced applications.
