HP32sII - Strip metal twisting Message #17 Posted by Vieira, Luiz C. (Brazil) on 10 May 2003, 3:04 p.m., in response to message #16 by Nick
Hey, Nick; that's good news! Thank you for your feedback.
I forgot to mention: look out for ElectroStic Discharges (ESD); take precautions, O.K.?
About the strips: I think if you do not bend them too far (I try to keep it in a less-than-90_degrees profile) they will survive after about a dozen twist-untwist porcedure. I can tell you I have gone that far or even more in one single Pioneer.
There are two two other things I have to tell you.
1) As you may have noticed, the two bottom strips (thanks; I'm collecting English terms as I see them replcaing mine...;^) at the extreme sides are different of the other four ones. They have two angled edgeds while others have two small tabs (strips?)at each side, like small forks, to made electrical contact. It's not critical, because if you look at the conections face of the mainboard, you'll see there are at least four "pins" connecting the positive pole (batteries). The tip is to slightly bend the small tabs that exist in the fork-type strips in the same direction they are already bent, before untwisting the strips when removing the mainboard, so they will scratch the surface slightly too, while you'll have to carefully straighten them back when they are under the mainboard's hole so you can remove it.
2) when you are placing the mainboard back, make sure you press it a little while you are twisting the sritps (I know there is a best sequence, but I did not stop to reason about it). This way the "small forks" will not scratch the mainboard too deep and when you release the mainborad (cease the preassure) it will remain a reasonable amount of pressure over both polymers and the keyboard's foam.
In time: the use of tape under the keyboard's contacts is not my idea; instead it was posted a few days ago by one of ours valuable contributors and I tested it so it works great.
About reassembling the case: the "trick" I use is to tear small slices of plastic appart from the border of the top (melted) internal posts (five or six?) so they allow being inserted back without much preassure and they still keep holding the case. The four ones that can be accessed outside after removing the batteries compartment cover I use one of both: heat glue or, when available, small screws. I prefer the second one, the problem is to find the d.. screws that fit in there.
Success. And let us know about the final results...
