Flexible Solutions

Digital displays are an integral part of modern vehicle dashboards, household appliances, consumer electronics, and more. In applications like thermostats, cell phones, smart watches, and vehicles, displays allow a simplified, interactive experience for users. To make these digital display assemblies, manufacturers require a variety of die-cut components that, when combined, come together to make an impressive display that provides extreme clarity and a user-friendly experience, which we highlight below.

In the fast-paced world, electronics are now integrated into almost every aspect of human life. Solutions ensuring optimal performance and longevity are necessary to meet consumers’ expectations. Many converted electronic components are made using materials that address various challenges faced by electronics applications, including thermal management, electromagnetic interference (EMI), surface protection, and more.

The rapid advancement of the electric vehicle (EV) market is no secret, and to keep pace with this progress, OEMs seek cutting-edge thermal management solutions that perform well and come at a reasonable cost.

Combining Intricate Laminations to Create Multifunctional Parts

Electric vehicles (EVs) continue to experience a sharp growth trajectory, generating process advancements and additional application requirements and needs. Marian has developed improved solutions to meet the industry’s most critical necessities for battery longevity, performance, and passenger safety.

Thermal Runaway Propagation Prevention with Thermal Barrier Materials

Marian provides custom flexible die cut solutions that are incorporated into battery design at the cell, module and pack level to aid with thermal management. These die-cut parts are made with high temperature resistant materials (also known as flame barrier materials) that are designed to offer thermal insulation to delay the onset of thermal runaway.

Thermal gap pads are one common type of thermal management materials and are utilized in electronic devices within the interface, or gap, between a heat generating component and a heat sink. The heat sink or cooling plate is designed to conduct heat away from the heat generating component to keep it cool and running safely.

According to Parker Chomerics Thermal Management Engineering Handbook, the typical contact area between most semiconductors and heat sinks can be made up of 90% air voids! We also know that air is about 200 times less conductive than a 5 W/mK thermal interface pad. This is where the thermal gap pad comes in.

Thermal gap pads are made of soft polymer that flows into the air gaps in the interface to aid in the more efficient and effective conduction of heat.

Improvements are being made to the lithium-ion batteries used in electric vehicles. Auto makers are developing more powerful lithium-ion batteries that have increased range and charge more rapidly. Along with these improvements, enhancing safety has becoming increasingly urgent for electric vehicle development.

As mentioned in our previous blog post, 11 Considerations when Selecting Thermal Interface Materials for Electric Vehicle Li-Ion Batteries, Li-ion batteries produce a significant amount of heat while in use and while charging. Along with the use of thermal management materials, placing protective engineered flame-retardant insulating materials between the components of the battery cell, module, and pack can offer additional thermal and electrical insulating protection. However, adding such materials can be challenging due to space and weight constraints.

In this post, we outline four materials that can enhance the safety of lithium-ion batteries used in electric vehicles. Some shared characteristics of these four materials are listed below. 

• ultra-thin
• lightweight
• electrically and thermally insulating
• flame retardant
• can be die-cut and laminated with PSA

11 Considerations When Selecting Thermal Interface Materials for Electric Vehicle Li-ion Battery

Currently, lithium-ion (li-ion) batteries are the most common type of battery used to power electric vehicles. Today's market is demanding that batteries charge faster and last longer. Because li-ion batteries produce significant heat when in use and charging, thermal management is critical. Excessive heat can cause irreparable damage to the battery. 

Video Demo: Thermal Resistivity and Conductivity of Silicone Foam

Thermal resistivity and thermal conductivity can be two very important physical features of foam materials for certain applications. Most devices containing electronic components must be designed to deal with heat in one way or another. Electronic circuitry operates most reliably at lower temperatures. High operating temperatures decrease the service life of the device or module. It is critical for designs to either conduct or isolate heat away from delicate components to ensure ideal operating temperatures.

Nitto TR Thermally Conductive Adhesive Tape Series

\Nitto’s TR series is a must-have for thermal and electronic applications. The TR series features a selection of double-coated tapes including TR-5912F and TR-5925F. These tapes exhibit powerful adhesion and thermal conductivity which accounts for their strength and reliability. Nitto recommends replacing the use of a screw-in an LED or other thermal applications with these thermally conductive adhesives for the best performance. Using the tape method offers superior thermal conductivity performance, and can extend the life of your LED, compared to using the screw method.
