[HP-41CL] Time Module Implant

[Garth Wilson]

I'd have to say some of those on that page are kind of like the dangers of a vending machine falling on you. Has it happened? I understand the answer is yes, but doggone it's rare. I have designed many high-density multilayer boards, up to 500 parts and 12 layers, and gotten them into production, and then been the one responsible to fix the rare failing unit, and I've never seen a via or thru-plating fail due to heat. Never. It apparently was an issue before I got into the field in the early 1980's, but that was 30 years ago. If you solder a wire-wrap (or other very thin) wire into a via hole (so it goes all the way through), I expect it would actually improve the reliability.

Is the news saying that halfnuts can now take the CL implant, or only that the cx's time module can be used in place of the plug-in time module? (Either way it's good news.)
