Due to electronic design It is an important activity in supporting the upgrading of Thai entrepreneurs to develop their own products using advanced technology in accordance with government policy. Electrical and Electronics Institute has established an electronic design center or Electronics Design Center (EDC) with the objective of providing design and development services for electronic circuit board prototypes (Printed Circuit Board or PCB) with industry standard quality as well as disseminate PCB design knowledge to entrepreneurs. Electronics design center (EDC) is located in FabLab Bangkok, inside the KX Knowledge Exchange building, which is a maker space for startups, researchers, and product developers. Come together to exchange, learn, and create innovations. They have access to advanced tools, equipment, and technology.

EEI Services / Electronic design services / Electronic circuit board design service (PCB Design)

For designing the electronic circuit single-side, double-side or multilayer following the requirements and conditions of the customer by using a program that is accepted worldwide according to standard of design, standard of production or product specifications as an Electromagnetic Compatibility (EMC) including PCB design that have IoT functions for Smart Farm, Smart Home or healthcare applications.

PCB Design Steps

1. Schematic Design: Building a block diagram to show all electronic components and routes together.
2. Board Layout: Creating a layout for importing the component or device (footprint) from the schematic to arrange the components that can wire signal lines connecting.
3. Material Selection: Choosing the component that suits for PCB by considering each factor such as heat transfer efficiency, insulator and durability.
4. Layer Planning: The planning of the number of copper layers determined by the circuit. Complexity might have many signal lines, so the number of copper layers and arrangement of components was an important step.
5. Trace Routing: Designing the connection path on the PCB to connect each component and the complex circuit design of signal lines considering electromagnetic interference and electromagnetic compatibility (EMI/EMC).
6. Component Placement: The arrangement of electronic components is one of the keys to making an efficient PCB and making sure that easy to manufacture and assemble.
7. Testing and Validation: Simulate the design of PCB to check a problem that might occur as a short circuit, signal integrity or electromagnetic interference.
8. Manufacturing file Preparation: The preparation file for manufacturing and assembly is included with the requirement.
   – Gerber files for manufacturing the PCB.
   – NC Drill files for drilling the PCB.
   – Bill of Material (BOM) files for supply and order electronic components.
   – Pick and Place files for details of XY and locate each component for use with the machine.
   – Assembly Drawing details of position and direction of the component.
   ** Details of the manufacturing file mentioned above are just one part of the manufacturer and assembly of the PCB that depends on the industry has technology.
