You know the scary part about your mentioning a tread where I post something? Well. let's just say that 2007 was a long time ago. Anyhow, silver will dissolve into your solder and provide no barrier. Some people apply a silver flash plating over the

Strange indeed. We use a Q18 and have never seen this. Is it sweating inside the thermal barrier case, i.e. you put it in the case dry and it is wet when you take it out of the case? Maybe its actually coming from the inside of your thermal barrie

�..... their material acts as a barrier to oxidation," is wrong Mr. N. The MS2 material "consumes" oxides therefore removing the oxides from the dross by chemical reaction and releases the pure alloy. It is not a barrier and does not mix into the sol

Pavel, We had exactly the same kind of problem with exactly the same type of component. Our components were well within their best before -date so it is not question of that. As we could not get it to work we changed to nickel barrier finish on the

Ya its doing it in the thermal barrier. We run it through the oven and it comes out sweaty.The thermal barrier is bone dry from the beginning. This only occurs on the first run of the day. I don't know how it would make a difference but our logger i

It sounds like what you are seeing is leaching of the end cap. You need to check the manufacturer's spec. Many components have terminal barriers, which get a solder plating. Sometimes this plating process is not done well, and the solder plating le

You should be able to solder to brass - check with you flux supplier to get their recommendations. The flux you are using may not have enough activation to breakdown the oxides on the brass surface. A word of caution - brass (copper and zinc alloy)
