白色阻焊油墨脱落改善探讨

Discussion on improvement of white solder resist ink detachment resistance

针对白色阻焊油墨侧蚀及脱落的品质问题进行探讨,并分析其原因。通过相关试验测试,对比不同曝光能量、前处理、曝光机光源波长等对油墨侧蚀及脱落的影响程度,重点探讨了LDI曝光机、LED平行曝光机和卤素灯平行曝光机的不同光源波长对阻焊油墨的差异影响。结果显示曝光机的波长大小对白色阻焊油墨侧蚀大小、附着力不佳脱落方面的影响存在较大差别。研究成果可为同行制作白色阻焊油墨提供一定的参考依据。

This article mainly discusses the quality issues of side erosion and detachment of white solder resist ink,analyzes the reasons for poor side erosion and detachment of ink,and compares the impact of different exposure energies,pre-treatment,and wavelengths of exposure machine light sources on the side erosion and detachment of ink through relevant experimental tests.The focus is on exploring the effects of The different light source wavelengths of the LDI exposure machine LED parallel exposure machines and halogen lamp parallel exposure machines on solder resist ink.The results show that the wavelength of the exposure machine has significant effects on the size of side erosion and poor adhesion of white solder resist ink,providing a certain reference basis for peers in the production of white solder resist ink.
