Generally, the most commonly used components in SMT package materials are package materials and plug-in materials, and each has its own advantages. Due to the advantages of miniaturization and precision, SMT processing occupies an increasing share in electronic processing, and chip components are the most widely used components in SMT foundry. Compared with plug-in components, SMT proofing components are small in size and low in cost, but plug-in components also have their own advantages, such as stable performance, good heat dissipation and better shock resistance.
Comparison of the advantages of the patch and plug-in materials in SMT proofing.
Patch components:
1. The defect rate of solder joints is low.
2. High reliability and strong anti-vibration ability.
3. Good high-frequency characteristics and reduced electromagnetic and radio frequency interference.
4. Light weight: The weight of SMD components is only 10% of that of traditional DIP plug-in components. Generally, after SMT, the weight is reduced by 60%~80%.
5. Small size: The volume of SMT chip proofing components is only about 10% of that of traditional DIP plug-in components. Generally, after SMT chip proofing processing, the volume of electronic products is reduced by 40%~60%.
6. Low cost: SMD processing is easy to realize automation, improve production efficiency, save materials, energy, equipment, manpower, time, etc., and reduce the cost by 30%~50%.
Component advantages:
2. The failure rate of plug-ins is lower than that of SMT chip proofing, and the inspection is more convenient.
1. When using electronic products with high heat dissipation requirements, the performance of plug-in components will be better than that of SMT-processed patches, because the heat dissipation effect of plug-in components is very good compared with that of SMT-processed patches, and the use of plug-in processing in SMT package materials will have a better effect on the stability of product performance.
3. Stability plug-ins that face bumps and vibrations in extreme environments will perform even better. Different components have different advantages, which requires engineers to make a comprehensive consideration in the electronic design stage, so as to select the appropriate components and make SMT processing achieve the best effect.
