I have been working with PCBs for explosive gas environments, such as LPG filling plants, for about three years. This is the place where I gained the most practical PCB design thinking patterns and in-depth knowledge. The course provides a clear understanding of how to design highly sensitive PCBs while considering PCB stack-up effects such as internal capacitance and inductance between layers. I have not seen any other course in Sinhala that delivers this level of practical and technical insight. This is excellent. Prior to this, I attended PCB and embedded design training programs conducted by leading universities in Sri Lanka. Those programs mainly focused on PCB layout design using Altium Designer and EasyEDA. However, this course goes beyond software tools and teaches advanced industrial-level design concepts. Highly recommend.
