Seven Levels of Interconnection (LOI) in Connector Packaging

When we integrate electronics into building and architecture environments, the number of connection points is no longer limited to the confines of a product package. By William Garver, APEX Electrical Connector Consultants LLC There are various Levels of Interconnection (LOI) in the electrical connector packaging field. At every interconnection point, at every level, there isRead More

PAM4 Extends the Life of Legacy Connectors

Replacing traditional signaling with four-level pulse amplitude modulation (PAM4) may be exactly the solution the industry is looking for. System design engineers have been dealing with the challenges elicited by ever-increasing data rates for many years. High-speed connector manufacturers have collaborated with their bleeding-edge customers and chip manufacturers to develop cost-effective interconnects that deliver aRead More

One Waterproof Connector Does Not Fit All

A host of variables define a waterproof connector. Here’s how one company helps its customers get exactly what they need. Roy Phillips, Managing Director, Intelliconnect When a customer asks a supplier for a waterproof connector, their exact requirements are often unclear.

In Search of Standards: A Look at the iNEMI Connector Reliability Test Recommendations Project

A survey of industry experts underscores the need to develop standard reliability testing protocols for connectors.   Consistently testing the reliability of electrical connectors across types and use cases is a major challenge in the connector industry. Electrical connectors come in many shapes and sizes, and differ in use. In general, the purpose of anRead More

Tribology and the Effects of Motion in Connectors

Tribology is the study of the science and engineering of interacting surfaces that are in relative motion, and includes the associated principles of friction, lubrication, and wear. So how does tribology relate to connector interfaces?   Although connector contact surfaces are usually not intended to be in continual relative motion, often the surfaces do experienceRead More

The Importance of Value-Added Services and Manufacturing

In today’s competitive market, value-added service providers help manufacturers reduce costs and lead times, while increasing throughput.   The term “value-added services” can encompass a wide range of services, depending on the individual company or industry. However, in every industry, companies that offer value-added services aim to decrease time-to-market, lower costs, and ultimately improve responsiveness,Read More

Value-Add Providers Solve Customers’ Design Challenges

The model for providing value-add services grew out of the constant changes in product designs and life cycles that are so prevalent in this industry. Whether customers are in the aerospace, transportation, or factory automation markets, their requirements for reliable, high-quality connectors and cable assemblies evolve quickly, and yesterday’s demand can’t always forecast future needs.Read More
