Sustainability is one of the most widely used terms in business today, especially for electronics and manufacturing but what does it mean to you? We explore the environmental, business, and economic impacts.
The Fabricator’s Guide to IPC APEX EXPO
This issue previews many of the important events taking place at this year's show and highlights some changes and opportunities. So, buckle up. We are counting down to IPC APEX EXPO 2024.
Getting to Know Your Designer
In this issue, we examine how fabs work with their design customers, educating them on the critical elements of fabrication needed to be successful, as well as the many tradeoffs involved. How well do you really know your customer? What makes for a closer, more synchronized working relationship?

Eurocircuits Enhances IMS Pool Service
March 27, 2018 | EurocircuitsEstimated reading time: Less than a minute
More powerful LED applications demand an increased focus on thermal management. More powerful LEDs produce more heat and temperature rise has an impact on the short-term function of a LED part such as color shift and reduced light output.
The long-term effects shouldn’t be neglected either. Higher operating temperatures can result in a reduced life time.
To reduce the operating temperature, and thus the impact of the temperature on LED applications or power converters, Eurocircuits has upgraded its IMS material. The formerly used Polytherm TC-Lam 1.3 is now succeeded by Polytherm TC-Lam 2.0.
The main difference is the dielectric. This thermally conductive layer has better properties, such as thermal conductivity of 2.0 W/mK (upgrade from 1.3 to 2.0), and thermal resistance: 0.50 K/W (lowering from 0.77 to 0.5).
The thick aluminum (alloy 5052) layer remains the same and is responsible for the heat dissipation. The copper foil on the opposite side is still 35 microns thick. This copper layer forms the base for the circuit. Other service parameters remain unchanged.

Trouble in Your Tank: Supporting IC Substrates and Advanced Packaging, Part 5
03/19/2024 | Michael Carano -- Column: Trouble in Your TankDirect metallization systems based on conductive graphite or carbon dispersion are quickly gaining acceptance worldwide. Indeed, the environmental and productivity gains one can achieve with these processes are outstanding. In today’s highly competitive and litigious environment, direct metallization reduces costs associated with compliance, waste treatment, and legal issues related to chemical exposure. What makes these processes leaders in the direct metallization space?

The Chemical Connection: Getting to Know Your Vendor
02/16/2024 | Don Ball -- Column: The Chemical ConnectionAfter working for a capital equipment supplier for almost 50 years, I’ve found that the most important part of getting to know your vendor is good communication among all parties. While contact between fabricators of a constantly changing product line and the designers of those products may occur daily or weekly, conversations between you and your equipment supplier may be years apart. That lengthy gap often means that previous contacts may have been promoted, retired, or moved on to other opportunities. You may have also migrated to a new supplier with whom you have little or no history. In either case, you will be interacting with someone you are unfamiliar with (as they are with you). Therefore, it is essential for both sides to communicate clearly so expectations will align.
EIPC Winter Conference 2024, Day 2: A Closer Look at Global Trends
