OTC "Silasitc"?

(1/9) > >>

ender4171:
Dave and others often talk about components being tied down with silastic.  I have found the OG Dow/Corning 732 stuff, but it is pricey and not available in small quantities (way more than I would use in time without it going bad).  Is there anything really special about it other than it is a neutral cure silicone?  I was thinking of grabbing some GE Silicone II, which is also neutral cure and is available at any home store in small tubes.  Does anyone have experience with that product, or have any recommendations for an alternative that is readily available?

Ill give you a cookie if you make mechanical mounts for your parts rather then hosing it down in xenomorph juices

ender4171:
Maybe "hold down" was a bad choice of words.  This is for vibration mitigation on things like capacitors.  Hard mounts would of course be ideal, but they aren't practical for small-medium sized parts, especially when the board is densely populated.  I am talking about this sort of thing:

Please show your 'mechanical mounts' for PCB mounted capacitors, transistors, resistors, inductors...  :bullshit:

I'd never heard the term "silastic" until watching EEVblog. I think it just refers to a type of silicone glue that cures to a rubbery state and is non-corrosive. I'm pretty sure a lot of manufacturers just use hot glue of some kind, which is what I do.
