This article will deeply compare PCBA and PCB! We will start with their basic definitions and principles, exploring the key differences in design, manufacturing, and practical applications. You will learn how PCBs are constructed and how they differ from fully assembled PCBAs. We will also explore real-world application cases across various industries, discuss manufacturing and … Read more
SMT, short for Surface Mount Technology, originated in the 1960s, involves directly mounting SMD components onto PCBs. Its greatest advantage is the high wiring density per unit area of each component, which shortens connection lines and improves electrical performance. Below, I will quickly guide you through the SMT process flow. (This is SMT) 01 SMT … Read more
From slash-and-burn agriculture to mechanized production, every transformation in agriculture has profoundly impacted human civilization. Today, amidst the wave of digitalization and intelligence, agriculture is ushering in unprecedented opportunities for transformation. Sensors have replaced the experience of traditional farmers, algorithms have optimized millennia-old farming practices, and behind this is a series of precision electronic hardware … Read more
Why Use Lead-Free PCBA Lead-free processes use environmentally friendly solder, aligning with modern green trends. Lead is a toxic heavy metal, and prolonged exposure to lead-containing materials can pose potential health risks to operators, while the disposal of lead waste can also pollute the environment. Additionally, lead-free solder has a higher melting point, typically between … Read more

In cases where the specific appearance standards conflict with customer requirements, customer requirements shall prevail in principle. 2. Scope: This standard references IPC-610D (for dedicated service electronic products) PCBA appearance inspection standards and is applicable only to … Read more
1. What Are the Inspection Standards for PCBA Boards? First, let us understand the introduction of quality inspection standards: 1. Critical Defects (denoted as CR): Any defect that can cause harm to humans or machines or endanger life safety, such as non-compliance with safety regulations, burning machines, electric shock, etc. 2. Major Defects (denoted as … Read more
