Are you (like me) just a little bit extra? Do you often make things WAY harder than they need to be? Have I got the keeb mod for you!
After applying each layer of tape to your pcb go ahead and throw the whole unit in a vacuum seal bag for MAXIMUM tape to board contact!
Will it make any noticeable difference? Probably not. Does it look awesome? Uh-huh! Does it scratch your itch of needing to feel different and sightly superior than the masses? Abso-fricken-lutely.
Don't give me any ideas, I have an immersion circulator and this is exactly the stupid kind of shit that gets me in trouble with the wife.
Although now that you mention it, if I could figure out a good tempurature to increase the elasticity of the tape I could get a better seal around the chips and....... yeah prolly better not.
"yeah prolly better not." ...erm no, fuck you, do it!
