A study of characteristics of halogen-free prevented solder materials

Green electronic products are more preferred in the recent era, especially in lead-free and halogen-free manufactures. A brand-new halogen-free solder resist, AUS320, provides the good performance, compared with the popular low-halogen AUS308 such as in halogen concentration, flatness on cavity surface and roughness on cross-section as well as the optical and thermal reactions.
