High packing density, electronic products, small size, light weight, SMD components of the volume and weight of only about traditional cartridge components 1/10, generally after SMT electronics volume 40%~60% and weight 60%~80%. High reliability, vibration-resistant ability. Solder defect rate is low. High frequency characteristics. Reduces the electromagnetic and radio frequency interference. Easy to automate and improve production efficiency. Reduce costs by up to 30%~50%. Save on materials, energy, equipment, manpower, time, etc.
