Surface Mount IC

When the surface mount resistors are shown for the first time?

I am looking for historic information on surface mount resistors and capacitors and inductors. In particular, I wonder if the first part were presented for surface mount (what year). I would also like a timeline for the change in size for each of the more than a year in each size CMS established resistance. Suggestions?

When I started in electronics in 1982, SMT resistors and caps have been widely disseminated. Perhaps some of the largest sizes were developed later. We have introduced market SMT IC packages of approximately 75 by 85. Some fine pitch and high lead-count types are in progress. Through the 80s and 90s, there was a lot of CMS-inducing and other components (triac, etc.). By SMT Wiki started with IBM in le'60 's. The Saturn V computer, he points to the resistance of film thick on the small screen hybrid modules, typical IBM. So we are not using caps and 1964 chip resistors.

Standards Organizations: EIA / JEDEC and EIAJ (Electronic Industries Association; Common Council Electronics Electronic Devices, IEE Japan). These standards committee to define the sizes of components, usually requires 2 – Standardization 5 years after its first use. Seek review of the history of the specifications, the old rev is probably still available or of the organizations. 3. Search for SMT devices such as computers and how they were made. You can view the online museum to see the technology used. Old newspapers, and electronic news are probably available somewhere. Announcements of products they have. 4. There are analytical market companies doing market research. You can further study if you know how to obtain them. Good luck!
