▲ Click the public account card above to follow for more information ▲ A packaging library mainly consists of two parts: pads and graphics. The position and size of the pads determine the soldering conditions, while the graphics serve to visually represent the component status, assisting in design and guiding component assembly. We have discussed … Read more
[Click on the public account above] ▲Get a free collection of learning tools▲ In PCB design, pads are a very important concept, and PCB engineers are certainly familiar with them. However, despite their familiarity, many engineers have only a partial understanding of pads. Today, let’s explore the types of pads and the design standards for … Read more
Many people have experienced making mistakes in PCB packaging—either making it too large or too small, or even having components obstructed, which leads to issues when soldering components after the PCB is manufactured, sometimes requiring manual wire connections; in severe cases, it may even result in the entire board being scrapped. For example, the U8 … Read more
Recently, a friend asked me if I knew any PCB design masters who take apprentices. I replied that I do, and asked if he wanted a recommendation. “Is there a fee?” he asked, which caught me a bit off guard. “Yes, the specific fee needs to be discussed with the master,” I answered. He countered, … Read more

4.1 What is PCB packaging, and what are its general classifications? Answer: PCB packaging refers to the graphical representation of various parameters of actual electronic components, chips, etc. (such as component size, length and width, through-hole, surface mount, pad size, pin dimensions, pin spacing, etc.) for use in PCB design. 1. PCB packaging can be … Read more
Flex Power Modules has launched an upgraded version of its BMR510 dual-phase integrated power module. The new BMR5101041/002 version not only improves efficiency and increases the peak current from 140A to 160A, but also includes a 528μF onboard output capacitor, significantly enhancing transient response. This onboard capacitance reduces the need for customers to add external … Read more
