Plymouthy Adams Posted March 10, 2021 Report Share Posted March 10, 2021 (edited) electronics solder can be corrosive but ever so lightly....that which is marked RMA is Rosin, mildly activated. However if you wipe good with alcohol and clean up the surface....your odds at corrosion is very slight. Also they are reducing and or eliminating lead content in solder. The content is high in tin, for our use little concern here....but if you have ever had the pleasure to view a circuit card loaded with microprocessors and memory chips galore literally shorted by tin whiskers....amazing how this stuff will grow metal hair.....got a pot load of circuit cards sent to me from a well known R&D lab to troubleshoot and repair as all of a sudden nothing was working for them....amazingly after cleaning the boards of the whiskers...all was well with the world....I conformal coated the cards to prevent this...as they were R&D they did not coat and thus the oxidation issues.

lonejacklarry Posted March 12, 2021 Report Share Posted March 12, 2021 I have a Fluke 107 and it works fine for me. The auto-off is set for 20 minutes which seems a little long but there it is. The backlight goes off a lot quicker. Quote Link to comment Share on other sites More sharing options...
Rodney_Hamon Posted March 13, 2021 Author Report Share Posted March 13, 2021 WOW. Didn’t know any of this! I just never thought to open up a device and understand how anyone could invent that. Thanks for the knowledge sharing. Quote Link to comment Share on other sites More sharing options...
