The global electronics manufacturing industry is entering a period of intensive innovation and rapid development of emerging companies. With the rapid development of component packaging, more and more PBGA, CBGA, CCGA, QFN, 0201, 01005, 03015 RC components are widely used ,
Surface mount technology has also developed rapidly, in its production process, the welding quality is more and more attention by engineers. Because product functions are becoming more and more powerful, component body specifications are getting smaller and smaller, product layout is becoming more and more dense, defective products are becoming more and more difficult to repair, and people have higher and higher requirements for product quality;
in order to save costs, based on product quality And efficiency is designed and made, not the product that people often say is detected (misconception), ask why the visual inspection did not detect it? Rarely say why so many bad things are produced?
How can we avoid bad production? It can reduce or avoid bad missed inspections, reduce customer complaints, and improve reputation. Therefore, this analysis is formulated in accordance with the principle of rooting the root cause, starting from the source, solving the abnormal problem of SMT welding, improving product quality, improving production efficiency,
saving production costs, and reducing employee pressure. .
