Ventec High-CTI Substrate Drives Increased Vehicle Electrification


Reading time ( words)

The increasingly complex typical vehicle electrical infrastructure, with many electronic control units (ECUs) positioned in harsh underhood environments where high humidity, -temperatures and atmospheric contaminants are expected, demands high reliability and durable materials for highest safety. Ventec International Group Co., Ltd. (6672 TT) has developed a high-CTI substrate (VT-441C) that offers an environmentally friendly, high-performance copper clad laminate that creates a stable and reliable platform on which to build ECU circuitry.

Increased electrification of vehicles is a trend now firmly entrenched, enabling more features, greater economy, superior reliability. ECU’s are positioned in harsh and distributed throughout the vehicle managing functions from critical safety systems such as airbag or ABS controllers to engine management and comfort features such as electric windows and electric seats. Reliability and thermal management is a must, so paying attention to the properties of materials at the substrate level is the first step towards achieving the most stringent performance targets.

The solution begins with high-performance substrate materials such as Ventec’s VT-441C high-CTI substrate that ensures reliability in the presence of high applied voltages in harsh and humid environments. With a Grade 0 (>600) Comparative Tracking Index (CTI) and a glass transition temperature (Tg) of 155oC, the versatile halogen-free material is the perfect choice for use in extreme high-temperature/humidity applications.

VT-441C is available in sheet or panel form with core thicknesses of 0.004” (0.10mm) to 0.200” (5mm).

Ventec International is a world leader in the production of polyimide & high reliability epoxy laminates and prepregs and specialist provider of thermal management and IMS solutions.

In this second half of our conversation, Michael Carano discusses some of the metrics that fabricators need to consider before investing in new processes, especially process control technologies, and some of the challenges board shops face updating brownfield sites.

Catching Up With John Johnson, New Director of Business Development at ASC

09/28/2022 | Dan Beaulieu, D.B. Management Group
It’s always good to catch up with old friends, especially when you can start working together. I recently spoke with my friend John Johnson, who has joined American Standard Circuits as the director of business development. At ASC, John will be using the Averatek A-SAP process that he was previously involved with. He shares some of his background and provides insight on the best ways to use this semi-additive PCB fabrication process that opens the capability window for forming trace and space.

A Focus on Process Control, Part 1

09/27/2022 | I-Connect007 Editorial Team
Michael Carano is a noted subject matter expert with respect to process control, electroplating and metallization technology, surface finishing, and reliability. So, it was only natural that we sat down to talk about mechanizing an existing facility given today’s fickle environment. Will any of the CHIPS funding trickle down to bare board fabrication? What process can be adjusted on the factory floor? The focus needs to be more than just on manufacturing and getting work out the door, he says, but also process control.
