moisture and electronics
micksmelanie:
If I have electronics stored in an anti-static zip bag and this bag inside a shoe box has any way to escape the accumulation of moisture inside the box and inside the bag?
the anti-static zip bag I left open for better air circulation
bob91343:
If you leave the bag open, of course moisture can accumulate. If you seal the bag, make sure first that you do it in a dry environment else you will trap moisture.
That's why silica gel is used, to absorb moisture that can corrode electronics.
jogri:
If you are paranoid about the level of moisture you could put your electronics inside a sealed bag, together with a moisture indicator like cobalt chloride paper and freshly baked silica gel (just leave it in the oven @150°C for a few hours).
Btw, why would those components need air circulation? Just close the bag (or use a ziplock bag) and you are good to go (as long as you don't store it in your shower).
micksmelanie:
I put 3 sachets of silica gel inside the box but I did not put 1 sachet of silica inside the antistatic zip bag because there is not enough space for the sachet so the bag stays open outside the bag is the box with the 3 sachets of silica
electronics inside that open bag zip antiestatic and that bag inside the shoe box and inside the box has 3 silica gel sachets protects from moisture?
jogri:
Silica gel bags only work in (nearly) airtight containers... Get yourself a big ziplock bag, put your antistatic bag AND the silica gel in and then close it. Btw, silica gel is absolutely useless after 3-4 days in open air so you have to heat those bags for a few hours if you want to use them (i don't know if the paper packaging of the silica gel can handle the heat so you have to get creative).
