Protect Against EMI with Die-Cut Foil Tapes

Posted by Katie Sullivan

Jun 8, 2022 8:26:16 AM

There are many EMI shielding materials to choose from when determining how to effectively control EMI within an electronic device. In this post, we focus on die-cut foil tapes for EMI shielding. Foil tapes with conductive adhesive provide effective shielding properties as the thin foil layer ensures good electrical contact with the component surface. Let's take a look deeper at EMI and why foil tapes may be the best-suited material for your application. 

What is EMI and Why is it Important?

Electromagnetic interference is unwanted “noise” or interference in an electrical path or circuit caused by an outside source. EMI can be caused by natural or man-made sources and can cause electronics to malfunction or to completely stop working. Therefore, EMI shielding and grounding components are important pieces in the design of electronic devices.

Medical Device Packaging for Converted Products

Posted by Katie Sullivan

Mar 29, 2022 1:01:05 PM

When designing a medical device, the device is the focus. It must be safe and effective. It also must be packaged!

Packaging can sometimes be an afterthought, but it is very important. Packaging design can impact the medical product’s success in the following ways:

  • Product appearance and how it compares to competitive products
  • Proper handling and ease of handling by the end-user
  • Storage efficiency
  • Sterilization and product integrity

Final packaging concepts should be considered early in the design process and should be included in the proof of concept, prototypes, product testing, and sterilization phases.

What are Double Coated Foam Tapes?

Posted by Katie Sullivan

Oct 27, 2021 8:53:20 AM

Double Coated Foam Tapes

Double coated foam tapes are a type of adhesive tape that is made of tacky adhesive coated on both sides of a foam core or carrier. DC foam tapes fill gaps and distribute stress uniformly over the bonded area. Depending on the specific tape, the result is a bond line that seals, cushions, and damps vibration, resists impact, withstands a wide temperature range, and provides good insulating qualities. Double-coated foam tapes are strong and durable.

4 High Performance Thermal Barrier Materials for EV Battery

Posted by Katie Sullivan

Thermal Runaway Propagation Prevention with Thermal Barrier Materials

Hybrid and battery electric vehicles that use lithium-ion cells require that these cells are maintained at specific ambient temperatures. "Thermal runaway" occurs as a result of the rapid rise in temperature within one of the battery cells. One of the greatest challenges for battery design engineers is to manage heat. For this reason, batteries are designed with thermal management systems that provide different levels of protection, including cell-to-cell, module-to-module, and pack level.

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.
