Since the COVID-19 epidemic in 2020, the medical industry has ushered in a new round of growth, and more and more medical equipment enterprises have also ushered in explosive growth, which has also brought new challenges to SMT patch factories.
Medical electronic SMT patch processing needs to pay attention to what matters, medical electronic products have their own special requirements:
Whether it is medical testing equipment or medical auxiliary equipment, it needs to be very high in the use of it. Things about life cannot be said about, about and so on.
High stability: especially for medical diagnosis and medical auxiliary tools and equipment, a high degree of stability is essential, the diagnosis of the diagnosis stage, the application stability of the clinical application stage.
Considering the special requirements of medical equipment, it is necessary to strengthen the quality control of SMT patch processing for medical electronic SMT processing plants.
1. Quality control of components: In the control of medical electronic components, we must first control the quality from the source of procurement. After the purchase is completed, IPQC shall conduct a full inspection of the components, seal the samples and put them into storage. Special BGA and IC shall be stored in a moise-proof cabinet.
2. Solder paste control: The patch processing of medical electronics must select and store solder paste according to the characteristics of the product, and the stirring and the addition of flux in the application process need to be strictly controlled.
3. Solder joint control: after the quality of components and solder paste is completely OK, the control of solder joint determines the quality of SMT patch processing, simply speaking, the quality of solder joint determines the quality of patch processing.
4. Static electricity control: static electricity instantaneous discharge can reach thousands/w, the damage to BGA, IC components is invisible potential damage, medical electronics in the use of considerable data need to deal with, if the core components because of electrostatic damage and loss of stability, will affect the stability of the product.
In addition, in the medical electronics patch processing, not only the above four points, there are many aspects that need manufacturers to work hard, truly be responsible for the product, responsible for the product user, is the problem that manufacturers must face.
