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
1. PCB Size 【Background Information】The size of the PCB is limited by the capabilities of the electronic processing production line equipment. Therefore, suitable PCB sizes should be considered during the product system design. (1) The maximum PCB size that SMT equipment can mount is based on the standard size of PCB materials, most of which … Read more
1. Working Principle The working principle of a circuit board is to use an insulating material to separate the surface copper foil conductive layer, allowing current to flow along a pre-designed route through various components to perform functions such as work, amplification, attenuation, modulation, demodulation, and encoding. Figure 1: Circuit Board 2. Components The circuit … Read more
Click Blue Text Follow us~ Today, I share an experience summary on PCB process design, hoping to inspire industry colleagues. 1 PCB Basic Technology 1.1 PCB Size and Shape The welding processing dimensions of the PCB material shape are width (200mm～250mm) * length (250mm～300mm). For PCBs with a long edge less than 125mm or a … Read more
Whether engineers or PCB manufacturers, they inevitably encounter PCB failures. The occurrence of these failures may lead to delays in product delivery, damage to the manufacturer’s reputation, and increased time and monetary costs. (Most importantly, it costs money.) Today, we mainly discuss PCB failure modes and solutions. (It is recommended to save for later viewing, … Read more
01 PCB Size [Background Explanation] The size of the PCB is limited by the capabilities of the electronic processing production line equipment. Therefore, suitable PCB sizes should be considered during product system design. (1) The maximum PCB size that SMT equipment can mount originates from the standard size of PCB materials, most of which are … Read more
Despite the increasing integration of semiconductors and the availability of off-the-shelf systems on chip for many applications, there are still many use cases where electronic products require custom PCBs. In one-time development, even a standard PCB can play a very important role. A PCB is the physical platform for design and the most flexible component … Read more
It is well known that PCB design always has a series of principles to follow. If these principles are not adhered to, it may lower the success probability of PCB design, affect product performance, and even have negative impacts on signal integrity, electromagnetic radiation control, and system reliability. Today, this article will analyze these principles, … Read more
