Douglas Electrical Announces New Hermetic Solution for USB 3.0

USB 3.0


Douglas Electrical Components is pleased to announce the release of a new line of USB3.0 solutions. In addition to historic USB2.0 products, customers will now have the option to choose between both cable feedthrough and PotCon© bulkhead connector styles for USB3.0 needs to accommodate their increased data and camera transfer speed requirements.

Offering speeds higher than USB2.0 and improved power management, USB 3.0 use is only on the rise and Douglas Electrical is poised to continue offering the highest quality solutions for some of the most demanding industries, including space simulation and glovebox testing.

Typical Douglas customization is available in terms of connector types, cabling lengths, and fitting choices that are most easily integrated for each application.  Offerings exist for both vacuum and high-pressure conditions and all versions come hermetically sealed to the expected Douglas quality standard of <1x10-8cc He/s.  

“Douglas Electric is proud to provide Potcon solutions for USB-A, USB-B and USB-C in 3.0 configuration,” said Chris Rempel, Director of Sales and New Product Development for Douglas Electrical.

“Although USB 3.0 was originally developed in 2008, regular production and commercial adoption lagged by several years. Douglas Electrical has just started seeing an increasing number of customers looking to take advantage of USB 3.0 data transmission rates, which are nearly 10x greater than those of USB 2.0.”

Although USB 3.0’s full duplex, dual-bus architecture created some initial challenges during development Douglas Electrical was able to balance the needs for hermetics with the electrical performance of USB 3.0 to provide a full hermetic seal, without affecting electrical performance. It is common in Nuclear Glovebox and Vacuum Chamber application, for customers eager to capitalize and push the boundaries of technology.

VIDEO: Improve Fuel Pump Reliability

Epoxy-based integrated feedthrough technology is a proven, effective way to seal the wiring of in-tank fuel pumps, reducing assembly time and potential failure modes. Douglas Electrical Components casts epoxy feedthroughs directly into the fuel pump to form a true hermetic seal around any wires that pass through the housing. Watch our new video to learn more about incorporating feedthroughs into fuel pumps.


How Hermetic Sealing Techniques Solve Manufacturing Defects | Douglas

In our last lean manufacturing blog post, we explored how making our manufacturing cells smaller has improved the use of our floor space and boosted overall factory efficiency. But the lean updates and improvements in hermetic sealing techniques, and hermetic feedthroughs don’t end there.

In an effort to continually improve our manufacturing practices, and decrease manufacturing defects, we turn now to “Asaichi,” which means “morning market” in Japanese. The word refers to the way Douglas Electrical tracks and eliminate various defects and disruptions that take place in our manufacturing cells.

Here’s how we do it:

The Asaichi Process
In our latest white paper (which you can read here), we discuss the seven forms of “muda,” or waste—a lean concept that includes all non-value-added manufacturing processes that eat up time, materials, labor or floor space without physically transforming the product into something the customer wants. Defects is one of the types of waste, and it refers to the effort involved in inspecting and fixing quality errors that often result in costly rework or scrap.

Last September, in an effort to identify, minimize and ultimately eliminate the defects and disruptions that take place in our cells, we initiated Asaichi. First, we categorize the various defects. For example, a product might need to be scrapped because the material quality was bad, or we were missing key information from the supplier.

The Daily ‘Morning Market’
To help manage Asaichi, a group lead is appointed to each cell. Whenever operators find a defect, they know to report it to the lead. The leads help us track the defects that occur in a particular cell, and then we summarize the findings visually on a large board. Each morning, the leads meet for 10 minutes to go over the reports from the previous day. We ask questions like: how have certain defects been trending over time? How can we get at the root cause of them? What’s the status of solving a particular issue?

These simple daily meetings—during which key information is shared by the leads—are at the heart of the Asaichi process.

The Impact Of Asaichi
Since initiating Asaichi last September, some of the recurring defects we’ve found in our factory have included missing information—either from the supplier or engineering team, for example. We also noticed issues related to the supply of certain parts. But after working on resolving these issues, productivity is up and the number of total defects in our factory is down significantly.
