Is there a danger of popping a surface mount tantalum capacitor because of absorbed moisture while hand soldering with a soldering iron?
Hand soldering surface mount tantalum capacitors
I’ve not had such a problem. It’s mainly with reflow ovens that the problem occurs.
Thanks Kartman. I knew some ICs had the problem of absorbed moisture but were OK to hand solder, but I didn't know tantalum capacitors absorbed moisture. After doing a Google on "soldering surface mount tantalum capacitors absorbed moisture" I learned that they are very porous and absorbed moisture can affect their performance, especially in high humidity environments, and reflow soldering can cause cracking. After reading what I found I am going to use fewer tantalums. Thanks.
Just about all components absorb moisture even the pcb. Ceramic caps and leds are major problems as well. Again rarely a problem when hand soldering.
Where hand soldering can be an issue is with large surface mount ceramics - hand soldering causes a temperature differential that can cause them to crack.
Thanks, Kartman. Good to know.
