This week, I’ve been attending Thailand Electronic Circuits Asia 2024. This is the inaugural event, hosted by Thailand Printed Circuit Association (THPCA) in collaboration with the Hong Kong Printed Circuit Association (HKPCA). Thailand has supported a PCB industry for some time—mostly automotive applications—but the China Plus One dynamic has definitely taken root here.

Industry certifications have become increasingly significant in the modern job market, offering a range of benefits to both individuals and employers. These certifications serve as formal recognitions of expertise and proficiency in specific areas, validating a person's skills and knowledge. In the context of the electronics assembly industry, certifications are particularly valuable, given the technical nature of the work and the rapid advancements in technology.

In circuit theory, we learn that current flows in a closed loop, returning to the source via a conductor pair. This flow of current provides power to the load, and energy transfer occurs as described by Ohm’s law (P = VI). Conversely, in electromagnetics theory, we discover that current does not provide the power in a circuit, but rather the energy wave is guided by the conductor to power the load, according to Maxwell’s equations.
