Hi We have recently noticed that our lead free solder wire is being supplied with expiry dates (typically 2-3 years after manufacture). I have seen "date of manufacture" information on wire before but I was not aware that a cored solder wire could e

Some print expiry date on reels and some specify a shelf life on data sheets. Two main reasons are that the flux in the wire is a mix of chemicals and over time in storage these can react so soldering performance can be changed. Although I have to sa

In addition to type of paste, it is also dependant on the enviroment conditions. When you say open jar are you implying that the jar is left open all day and then at the end of shift it is closed back up? Jars should only bve open for about 30 secs
