In the manufacturing process of electronic products, PCB and PCBA are two indispensable links. PCB is the carrier of electronic components, while PCBA is the finished product after the assembly of components on the PCB. Although closely related, there are many differences in various aspects. This article will detail these differences. 1. Differences in Structure … Read more
PCB, also known as Printed Circuit Board, enables the connection of electronic components and the realization of functions. It is also an important part of power circuit design. This article will introduce the basic rules for PCB layout and wiring. Basic Rules for Component Layout 1. Layout according to circuit modules. Related circuits with the … Read more
This article organizes some detailed issues that need attention in layout. Let’s check if you know them all! 01 Spacing of SMD Components The spacing between surface mount devices is a critical issue that engineers must pay attention to during layout. The spacing between components should not be too large (which wastes PCB space) or … Read more
Common PCB Wiring Rules (1) Pre-divide digital, analog, and DAA signal wiring areas on the PCB. (2) Separate digital and analog components and place them in their respective wiring areas. (3) Keep high-speed digital signal traces as short as possible. (4) Keep sensitive analog signal traces as short as possible. (5) Reasonably allocate power and … Read more
