When disassembling power boards or designing power-related PCBs, we often encounter structures like this: Figure 1: Common slot hole structure on power PCBs Many people think these slot holes are just for aesthetics or mechanical structure needs. In fact, their true function is closely related to electrical safety, and the key lies in one concept—creepage … Read more
PCEC Technical Article As an option to reduce the spacing requirements for conductive components, when the pollution level is controlled to level 2 or lower, the spacing and component isolation of printed circuit boards with ‘ic’ protection level assembly can use the reduced spacing shown in Table 1 under the following conditions. That is, if … Read more
▼ Follow the public account below for more information ▼ In high-voltage PCB design, attention must be paid to electrical clearance and creepage distance in switch mode power supply PCB design; insufficient distance can lead to leakage. General standards (varying by industry, such as lighting, electric vehicles, etc.) require certified products: design according to standard … Read more
