Protect Against EMI with Die-Cut Foil Tapes

Posted by Katie Sullivan

June 8, 2022 8:26 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.

What are Double Coated Foam Tapes?

Posted by Katie Sullivan

October 27, 2021 8:53 AM

 

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

April 26, 2021 11:16 AM

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, like thermal gap pads and thermally conductive tapes, 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.

Best Practices when Applying PSA and Storing Tape

Posted by Katie Sullivan

March 16, 2021 9:00 AM

The majority of the die-cut parts manufactured by Marian include a Pressure Sensitive Adhesive Tape (PSA). PSA tape is thin flexible material coated with a thin layer of adhesive, making one or both sides sticky. By producing billions of adhesive-backed parts each year, it’s safe to say Marian has a lot of experience with this sticky stuff!

PSA tapes can come in various constructions, which offer different functionalities based on your application. There are double-coated tapes, single-coated tapes, and adhesive transfer tapes. Check out our blog post, Pressure Sensitive Adhesive Tape Constructions, to learn more about different tape constructions.

The first step is choosing the best PSA type and construction for your application (by the way, we can help with this! Download our ebook: 4 Questions to Ask Yourself when Selecting a PSA). An equally important step when utilizing a PSA in the assembly of your product, is the proper storage and proper application of the PSA. Missteps when storing and applying your PSA can lead to product failure.

The Best Thermal Gap Pad for Your Design

Posted by Katie Sullivan

July 29, 2020 9:30 AM

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.

Ever wonder why hospitals, doctor’s offices, and other healthcare providers don’t just use duct tape for bandages, wound care, and device fixation? Well, there are many reasons, but first, try sticking it to the skin and peeling it off. The main reason is simple: duct tape does not use a medical grade pressure sensitive adhesive.

Medical adhesives must be skin-friendly, non-migratory, and have a variable degree of initial tack and peel adhesion. Ease of removal, breathability, and durability also differentiate medical adhesives from other types of tape.

Application Story: Antimicrobial Sealing Gasket

Posted by Katie Sullivan

March 29, 2017 2:05 PM

In this newly released application story, a global designer and manufacturer of critical intercommunication devices experienced a gasket failure allowing moisture to leak and compromise the internal components of their console. It's remarkable the amount of damage a single drop of water can do. Moisture often contains impurities and minerals that remain even after the water evaporates. Between the moisture and these remaining elements, the contamination can cause short circuits, corrosion, and mechanical problems. A malfunctioning device leads to recalls, replacements, and eventually a poor reputation. The company in this story did NOT want to deal with any of this. 

The intercom console product was intended to be used in medical office settings. Cleanliness and sanitary standards were very important for the high-touch surface of this device. The console was sprayed with liquid cleaners often. The console housing required a reliable sealing gasket to keep moisture out.

Marian has a brand-new demonstration piece to share with the world! Strategically named "Test My Memory," the demo illustrates the impact of compression cycling over time with 4 different foams. Neoprene, Polyethelyne, PORON Urethane, and BISCO Silicone are tested by being compressed for 48 hours.

 

Foam Material Compression

In the demonstration, you will see that certain foams depreciate as they take on impact over time, whereas other foams resist the compression set by returning to their original thickness. The material characteristic of being able to take a compression set, also called compression force defection, is extremely important in long-term sealing applications. The ability of the material to "push back" to fill in any potential gaps that would allow water or dust to pass through is critical. This makes such materials an excellent option for sealing gaskets.

PTFE Membrane Vents for Protecting LED Lighting Enclosures

Posted by Katie Sullivan

March 16, 2016 10:27 AM

PTFE membrane vents are made of hydrophobic microporous materials. This amazing PTFE material is designed to allow air to pass through while acting as a firm barrier to water and dust. 

Outdoor LED Lighting enclosures contain electronics assemblies that must be protected from the elements (rain, dirt, debris). As LED lights operate, they generate heat. As the enclosure heats up and cools down through the cycle of operation, the internal pressure changes. Without the ability to relieve this pressure, the enclosure can sustain damage and condensation can form. Both situations can be detrimental to the successful operation of the LED lighting system. 

PTFE membrane vents are a cost-effective way to protect your LED product. They keep dust and liquids out of the enclosure and relieve positive pressure or negative pressure within the enclosure.

Compression Force Deflection in Foam Gaskets: A Critical Property

Posted by Katie Sullivan

February 2, 2016 9:56 AM

Compression Force Deflection

Applications that experience periodic compression cycling over time may require a gasket that is capable of compression rebound. In the event that your application uses a material that does not resist compression force, the material may depreciate over time. When your gasket has dwindled or has deteriorated from all of the periodic compression cycling, your gasket will become ineffective and will need to be replaced. In a perfect world, your gasket should rebound to fill any potential gaps. Using a material with great compression resistance will guarantee a long-term sealing performance that will work just as effectively each time you reseal your application.

Thermally Conductive Materials in LED Assemblies

Although LEDs are considerably more efficient than traditional lighting forms, they do still produce heat. This heat can have an adverse effect on the LED and therefore must be managed to ensure the true benefits of this technology are realized. If excessive junction temperatures are reached, particularly above the maximum operating temperature of the LED (~120-150˚C), a non-recoverable effect could occur, leading to complete failure. Operating temperature is directly related to the lifetime of the LED; the higher the temperature, the shorter the LED life.

In this post, we briefly look at heat spreaders.A heat spreader is a heat exchanger that moves heat between a heat source and a secondary heat exchanger whose surface area and geometry are more favorable than the source. Heat spreaders conduct heat in the x,y, and z axes which spreads the heat to a larger surface area for efficient and effective heat dissipation. This heat dissipation keeps devices running at a safe operating temperature.
