+++++++++++++++++++ After a Surface Mount debate, Elecraft issued this "statement of direction" ? +++++++++++++++++++ Date: Wed, 08 Jan 2003 09:22:24 -0800 From: Wayne Burdick Organization: Elecraft To: Bill Steffey Cc: elecraft@mailman.qth.net Subject: [Elecraft] Re: Surface Mount tech; Orion; and K2/100 Hi Bill, > the real problem will come as the chip factories make the new cool chips > in surface mount ONLY.... zowie So far we haven't had to use any ICs that are available only in suface mount. But if we do, either because a through-hole part becomes obsolete or because we want to add a new feature that requires a surface-mount part, we'll have them pre-mounted on the PC boards. So you'll get the best of both: a kit that uses state-of-the-art components, while still being almost all through-hole (making assembly, alignment, and repair possible by real humans, with diminishing eyesight, who do not own microscopic tools). > when, not if, the market for thru the hole parts continues to diminish... > the chip guys will not have a market , and the SMTs will happen sooner. Note that Digikey--one of the largest electronic component suppliers--had dropped almost *no* through-hole parts from their catalog. They have added a lot of surface-mount devices (discretes, ICs, and connectors), and that explains why the catalog is twice as thick now as it was 10 years ago. The market for both is strong. The reason through-hole parts persist is that they exist at what I like to call the "unit of creativity": you can hold them in your hand, read their lables, and touch them with test probes that you can actually see. Just imagine how difficult it would be to use nuts and bolts the size of SMDs. They are below the size at which it's easy to manipulate them, so it only makes sense to use them if you have to for economic or technical reasons. Of course Elecraft might offer a small kit that uses suface-mount parts (the largest sizes only) someday just to give those who want it such a building experience. There is no other requirement to do so at this time. I believe that SMTs will continue to be used where miniature equipment size and/or mass production are necessary. But for many other niche markets where units are produced in the 1000's rather than tens or hundreds of thousands per year (hobby, medical, custom instrumentation), through-hole parts will still frequently be used.
