The success rate of first silicon for chips is sharply declining due to the increasing complexity of chip manufacturing, the need for more iterations as manufacturers shift from single-chip to multi-chip components, and the growing demand for customization, which extends the design and verification process. Details from a new functional verification survey highlight that developing … Read more
When designing electronic products, it is often necessary to evaluate hardware costs. What components make up hardware costs? They mainly consist of the prices of components, PCBs, and SMT, which together constitute the cost of PCBA. In other words, calculating hardware costs primarily involves calculating the cost of PCBA. Let’s learn about the methods for … Read more
Abstract With the rapid development of electronic products, the application fields of electronic devices are constantly expanding. From the past, where electromechanical products were limited to general industrial applications, to today, where electronic equipment is widely used in aerospace, navigation, military, and other fields. The broad application of electronic equipment means that higher requirements are … Read more
Based on years of experience in the maintenance and analysis of PCBA, we have categorized the maintenance methods into seven major types. Today, we will not conduct a detailed analysis of the PCBA circuit diagram, but rather provide a general overview of several methods we frequently use in repair analysis, as follows:1. Visual InspectionVisual inspection … Read more

1. From “Wolf Culture” to “Family Culture”: The Genetic Code of This Company I was staring at the annual report of Hongxin Electronics on my computer screen when a description caught my attention — “Sales Director Xu Xiaolan, who has been with the company for 19 years, choked up at the 20th anniversary celebration, saying … Read more
“The reason for this is that the solid-state drives (SSDs) provided with the computers at my workplace have been failing in batches. After testing, I found that some failures were due to interface issues, while others were due to problems with the storage chips. I can’t do anything about the damaged storage chips, but if … Read more
During the outbreak of the pandemic in 2020, I found myself staring at the K-line chart of PCB leader Huadian Co., feeling frustrated — who would have thought that a small circuit board could become the “throat” of the global technology supply chain? That year, when Huawei was cut off from chip supplies, the entire … Read more
