Surface Mount Device was here to stay and there was no turning back. Meanwhile the mains powered cassette radio was dead or as good as…Older mains cord fed/battery radios of the 1960s and 70s seemed like Dinosaur relics of a distant age all within 12-18 months of the first Sony Walkman device emerging. The batteries were smaller and they lasted longer. The cassette player shrunk significantly,seemingly overnight without anyone really noticing. Some walkman models had fancy light touch then called “fuzzy logic” controls the experimental forerunner of Jog/Shuttle controls seen later on Sony VCRs/Hi-Fi and Camcorders with tiny but utterly relaible digital servo motors. Surface mount chip devices were used in these, sometimes bonded on to the ribbon cables and becoming part of the cable harness itself and sometimes SMD components were used in pcb sub boards around the unit. They were compact, portable and sounded great. Perhaps the most iconic “ordinary” low cost devices created by smd technology was the Sony Walkman family of personal cassette and radio cassette players of the 1980s. Built in motordrives, super relaible autofocus and smaller,longer lasting batteries became reality.The Surface Mount Device was here to stay and there was no turning back. This was a major change as such technology was previously reserved for Aviation and Defence products manufacturers who had Govermnent backed unlimited budgets.Īt the start,35mm Cameras made by Nikon and Canon were in a surface mount device stratosphere right up there all on their own. It was Japanese companies that reduced manufacturing costs and SMD devices started to appear in their fine consumer electronics. Even today the process of “pick and place” is a commonplace in the electronics manufacturing industry but non the less it is an amazing process to watch. The SMDs could be glue mounted on to pcb boards by machines or robots then the board pcb run through yet another machine and bath soldered…ground breaking. For example, A capacitor or resistor could be made 1/20th of the size of a regular (THT) one. They offered manufacturers the advantage of making their final products much smaller. Unlike today, SMDs were very very expensive. There is a tantalum capacitor SMD to the lower right shoved in between 2 resistor packs.Īlso at the left in there is the point of my regular disposable paper mate ball point pen.Īs said these are are a few years old, there is a smaller resistor pack package now reduced by around 40%. You can see the 8 little tracks leading in and out of each SMD, one in and one out of each of the individual 22 ohm resistors. Here we see some regular Trough Hole Technology 1k resistors and some SMD 4 x 22 ohm resistor packs. This stuff was lying in the spares box and the bits shown here are about 5 years old or so. ![]() Quick photo from todays work bench in an attempt to show Surface Mount Devices (SMDs) and how much they changed electronics in terms of physical size. In the early days of Surface Mount Device production and implementation, Japan was the centre of the industry. It has top quality components which very interestingly are a mix of traditional/older THT (Through Hole Technology) mounted components and SMD (Surface Mount Devices) like the ones found in iphones and the like today. ![]() This model has great design and is much loved by airband fans due to its brilliant AM performance, no gaps coverage of both Civil and Military airband and beyond from 25mhz up to 1.3ghz. “The Pro-2006 is considered by many to be the best scanner ever produced in terms of sensitivity and selectivity.” One of the golden greats of 1990s scanner radios the Realistic Pro-2006 (also known as the Comtel 205 in European markets) was made for Radio Shack/Tandy by General Research Electronics Inc (GRE) Japan and designed and assembled in their factory in Chiba Prefecture. ![]()
