Teradyne Brand Guidelines: A Loft Over a Boston Hot Dog Stand, Diode Testers & Cobots

Two MIT graduates and a diode tester.

Teradyne was founded in Boston in 1960 by Nick DeWolf and Alex d’Arbeloff. Gale’s International Directory of Company Histories says the two were 32-year-old graduates of the Massachusetts Institute of Technology who had first met as students, when they lined up alphabetically in a Reserve Officer Training Corps class. DeWolf had made his name as an engineer at Transitron, a semiconductor company in Wakefield, Massachusetts, where he worked on germanium diodes and other components.

The name came first. DeWolf told the regional magazine The New Englander in 1974 that it “had to have a ‘D’ in it”: tera is the prefix for ten to the twelfth power and a dyne is a unit of force, and to the founders the pair meant rolling a huge boulder uphill, Gale’s history recounts. They then chose a place both men could walk to, close to the centre of Boston’s transit lines so that factory workers could get there easily: a loft over Joe & Nemo’s hot dog stand downtown. English Wikipedia tells the same story of the rented space above the stand.

Teradyne opened its doors early in 1961. Its first product was a go/no-go diode tester, and its first sale, at the end of that year, went to Raytheon. According to Gale, the idea was to bring the precise testing of the laboratory onto the factory floor, where manufacturers still relied on slow hand testers. From diodes the company moved on to testing resistors, transistors and integrated circuits.

The larger step came when chips grew too complex to test by hand. Teradyne began building minicomputers into its test systems, which Gale credits with creating the automatic test equipment (ATE) industry; DeWolf later designed the company’s own minicomputer, and he told The New Englander that the computer-controlled J259 integrated-circuit tester “made Teradyne the company it is.” In 1967 Teradyne moved into a nearby eight-storey building that had been a leather market, and in 1970 it sold stock to the public for the first time. DeWolf left in 1971, handing the company to d’Arbeloff, Gale says.

Testers for chips, boards and phones.

Teradyne’s products are machines that check whether electronics work before they leave the factory, and one of its founders wrote about that job in design terms. The industry history site ChipHistory reprints a list of rules DeWolf drew up in 1952 for factory production test equipment, while still an engineer at General Electric. Among them: equipment “should be reasonably neat in appearance,” because that instils confidence, it must “require a minimum of thought on the part of the operator,” and designers should “remember the operator, who is 2/3 of the equipment.”

In the 1970s the company widened its customer base beyond chipmakers, Gale’s history says. It set up a connector division in Lowell, Massachusetts, and from 1972 developed 4Tel, a system for testing telephone lines. After a slower period in the late 1970s, Gale adds, Teradyne raised its research spending, and the result was the J941 logic tester for very-large-scale integrated circuits in the early 1980s, which won an early contract from Intel.

English Wikipedia lists the acquisitions that shaped the modern range. In the 1980s Teradyne bought Zehntel, a maker of in-circuit board testers, and in the 1990s Megatest. In 2001 it added the circuit-board test business GenRad. In 2008 it bought Nextest and Eagle Test Systems, and in 2011 the wireless test company LitePoint, which English Wikipedia places in San Jose, California. The same article credits Teradyne’s 1987 A500 as the first analog VLSI test system.

Teradyne’s website now sorts the business into two halves it calls electronic test and task automation. On the test side it shows semiconductor testers such as UltraFLEXplus, the J750Ex-HD and the Magnum memory testers, alongside production board test, storage test, system-level test, optical test and defense and aerospace systems. The company describes its aim as making sure new products “work right the first time, every time,” and sets out its values under headings such as “A Company Without Doors.”

How equipment makers present themselves.

Semiconductor equipment makers sell to a small circle of customers: the chip manufacturers that run wafer fabs. Their machines deposit, etch, measure, test and package, and they are rarely seen outside a cleanroom. That shapes how these companies present themselves. The product is a large enclosed tool, and what happens inside it takes place at a scale no camera can show directly.

So the pictures tend to repeat. Corporate sites and annual reports show tools standing in rows behind glass, with panelled housings in white, pale grey or blue, and cleanroom staff in full gowns, hoods and gloves. A polished wafer held up to the light in a gloved hand is a familiar image, because it stands in for the chips the machines help to make. Fab interiors, lit evenly and seen down long corridors, give a sense of size and order.

Words do much of the work that pictures cannot. Makers describe their processes by name — atomic layer deposition, epitaxy, metal-organic chemical vapour deposition, wire bonding, wafer inspection — and give their tool ranges short product names and model numbers. Company histories, milestone lists and timelines are common, since many of these firms began as university spin-offs, sales agents or divisions of larger groups, and changed hands or split along the way.

Trade fairs remain a meeting point for this industry. SEMICON West and SEMICON Taiwan are among the shows where equipment makers set up stands, present new tools and meet customers. For a design guide, the pattern is a disciplined, technical register: cool colours, precise product names and photographs of clean, closed machines.

From downtown Boston to Nasdaq and Odense.

In 2006, English Wikipedia says, Teradyne sold its two Boston buildings and brought its Boston-area staff together at North Reading, Massachusetts, which remains its headquarters. Its shares, which Gale lists on the New York Stock Exchange in the 1990s, later moved: a Nasdaq trader notice announced that Teradyne would begin listing and trading on Nasdaq on 27 November 2018. The ticker is TER.

The automation half came by acquisition. In 2015 Teradyne bought Universal Robots, the maker of collaborative robot arms founded in Odense, Denmark, in 2005, English Wikipedia says. The same article describes Universal Robots as part of a Teradyne Robotics division, and says it broke ground in 2022 on a new Odense headquarters shared with its sister company MiR, a maker of autonomous mobile robots. Teradyne’s own product menu now lists collaborative robots and autonomous mobile robots next to its testers.

For a design guide, Teradyne shows how an engineering company’s identity can grow from a name chosen for its meaning and from machines meant for the factory floor rather than the laboratory. Compare Advantest, another maker of semiconductor test equipment, and KLA, a maker of chip inspection and measurement systems. For this guide we use a deep navy, white and a signal orange with a sans, an unofficial interpretation; no product or logo is reproduced.
