It is important to design electronic equipment with EMC in mind from the start. Compliance with regulations, safety and reliability from the very beginning will significantly reduce development costs. It is essential to ensure electromagnetic compatibility and reduce the risk of interference or malfunctioning. Here are some steps I consider when designing with EMC in mind:

• I am starting by understanding the EMC requirements for your equipment, including any applicable regulations or standards that need to be met.

• Select components with EMC in mind that are designed for EMC compatibility, including connectors, cables, shielding, and grounding components. I am trying to choose components that are rated for the specific EMC requirements that can fit in the device under development.

• Use proper grounding and shielding techniques that can help reduce the risk of electromagnetic interference. If needed I  usually choose grounding and shielding components, and take care to apply proper routing techniques to minimize the impact of electromagnetic radiation.

• Minimize the use of long cables that can act as antennas, picking up electromagnetic radiation and interfering with other equipment. Applying a smart component placement I am trying to use shortest possible cables if needed (display, motor, etc), as smart routing techniques as well to minimize the impact of electromagnetic radiation.
  

• Test and verify the EMC performance of device under development sc. precomplience, which is essential to early ensure compliance with regulations and standards. Those precompliance test usually include radiated and conducted emissions and susceptibility testing.

• Proper documenting my design process and the EMC measures I've taken. This helps me to identify potential issues, troubleshoot problems, and ensure that device under development meets the necessary EMC requirements.

Talking about EMC, it is almost impossible not to think about ESD performance. Those two characteristics somehow go hand in hand. Designing electrostatically robust devices involves implementing measures to minimize the risk of ESD damage. Here are some steps I consider when designing electrostatic robust devices:

• Starting by understanding the ESD requirements for the device under developmet, including any applicable standards or guidelines. This helps me to determine the level of ESD protection required.
• Using ESD protection components such as diodes, transient voltage suppressors, and capacitors to protect the device from ESD events helps shunt the high voltage spikes away from sensitive components, reducing the risk of damage.
• Defining a virtual ESD line that isolates input connectors or other inputs which can act as potential sources of ESD damage, from the rest of the design. The virtual ESD line is built of ESD protection components behind which is so called safe ESD zone. Shunting of high spikes is done before this ESD barrier and conducted to the ground shortest possible way. This approach is always minimizing the risk of ESD damage, ensuring that the developed device is electrostatically robust.

The above listed steps and techniques, for both EMC and ESD, I am using when I am in charge of full hardware development of a device, the whole chain, all from components selection, over hardware (schematic) design all the way to the PCB development,  and they help me to achieve good performances already form the very beginning. But, it is not rare case that some customers experience EMC/ESD issues with  an already developed device in which case I can offer help in solving problems with such devices.
