RE: Voyager keypad construction
The springs just serve to ground the metal plate on the back so that it shields against radiated RF energy. Nothing to worry about, I think they stand in a couple of holes along the sides. The nubs you mention are heat stakes, plastic posts coming up from the front of the case. During assembly the pcb is placed over the posts and then heating elements are applied to the top of the posts. That forms the nubs which hold things in place. This is obviously a one-way assembly technique!
Search the forum posts or articles for more information. It's best to use an external search engine like google or bing and add the site:hpmuseum.org qualifier to restrict the search. The forum search engine leaves a little to be desired. Good luck tinkering, ~Mark Remember kids, "In a democracy, you get the government you deserve." |
