Hello, This question is an extension of my previous question on this topic. We have found Alpha-metal Cleanline 7000 (cored wire solder) and NR205 (flux pen) interesting. Could anyone who use these share their experience? Cleanline 7000 is cleanable by both water and saponifier, but NR205 can only be cleaned by saponifier. If both are used on the same rework, saponifier is forced to be used if clean is required (for instance by customers). What are the pros and cons comparing saponifier VS water cleaning? Appreciate your help. Regards, Yuan Li Exabyte
