一、前言众所周知锡焊是目前电子工业装配最重要的工序之一。它的好坏直接影响着电子产品的可靠性和稳定性。与锡焊质量密切相关的是电子元器件引线和印制板等的可焊性的好坏,而提高电子元器件引线和印制板等可焊性的措施之一是选用优质助焊剂。所谓优质助焊剂就是助焊性好、无腐蚀、无毒、无刺激性气味及三防性能好的助焊剂。本文主要介绍近一、二年我们在研制优 First, the preface It is well known that soldering is one of the most important processes in the electronics industry. Its quality has a direct impact on the reliability and stability of electronic products. Closely related with the quality of soldering is the solderability of electronic components such as leads and printed boards, and improve solderability of electronic components such as leads and printed circuit board is one of the measures to choose high-quality flux. The so-called high-quality flux is a good flux, non-corrosive, non-toxic, non-irritating odor and three anti-performance flux. This article describes the past one or two years we are developing excellent
