Exporting circuit boards to the EU must comply with ROHS 2.0 (2011/65/EU) and subsequent amendments (such as the addition of 10 restricted substances), which primarily focus on controlling the content of hazardous substances in electrical and electronic products. Below is the complete testing process, key requirements, pitfalls to avoid, and recommended institutions, applicable for listing … Read more
1. Demand Differences: The “Personalization” Challenge of Microcontrollers In the world of microcontrollers, there is no “one-size-fits-all” solution. Imagine if a restaurant only offered one family-style meal; could it satisfy all diners’ needs? Clearly not. Similarly, the applications of microcontrollers vary widely: some projects require ultra-low power consumption, while others pursue high performance; some interfaces … Read more
1.PCBA PCBA stands for “Printed Circuit Board Assembly” and refers to the process of PCB boards undergoing a series of processing steps including SMT surface mount, DIP through-hole insertion, functional testing, and final assembly. 2.PCB Board PCB stands for “Printed Circuit Board” and typically refers to a circuit board, which can be classified into single-sided, … Read more
With the development of technology, the manufacturing process of electronic products has become increasingly complex, requiring highly automated SMT processing technology. PCBA SMT processing is a crucial step in this process. However, for many customers who are new to PCBA SMT processing, understanding the components of SMT processing costs can be a challenge. This article … Read more
Component costs account for 40%-60% of the total PCBA cost, and even a small decimal error can lead to losses in the tens of thousands. In electronic product design, accurately estimating PCBA costs is crucial for assessing project feasibility and controlling profit margins. Whether you are a hardware engineer, procurement specialist, or a startup founder, … Read more
Click the blue text to follow us In PCBA processing, there is a term that is repeatedly mentioned, which is the BOM (Bill of Materials). Some customers may think that the BOM is just a list of components, and sending an EXCEL spreadsheet is sufficient. Why is it referred to as a “lifeline”? Let’s break … Read more
