Flexible Solutions

In the 1960s, Dupont™ developed the versatile and high-performing Kapton® Polyimide Film. Since its introduction, designers have relied on Kapton® film because of its ability to maintain its electrical, thermal, chemical and mechanical properties at extreme temperatures. Kapton® films have been used in many advanced markets including, electronic devices, electric vehicle battery, aerospace systems, power transformers, and more.

Pull-tabs, extended liners and split liners are assembly aids. They make the process of removing the liner from a die-cut adhesive part much easier. When you work with Marian, we keep your manufacturing and assembly process in mind as we develop the solution. Our goal is to make things easier for you, saving you labor and time spent during assembly,  placement, or manufacturing. Once we understand how our part will be assembled into your product, we can often offer a variety of solutions. These solutions can include (but are not limited to):

• Part orientation / spacing on the liner
• Final packaging:
  • Kiss-cut to a liner and wound onto a roll
  • Singulated parts
  • Kiss-cut to sheets
  • Perforated liner
• Modifications to the carrier liner for fixturing
• Pull-tabs, extended liners, split liners

In this blog post, we are going to focus on pull-tabs, extended liners, and split liners.

Silicone rubber materials and some plastic films have chemically inert and non-porous surfaces, which equates to low surface energy. This means they have a weak molecular bonding force making it difficult to create a bond with many pressure sensitive adhesives.

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.

Point-of-care and rapid diagnostic testing are increasingly important in the areas of disease detection, treatment monitoring, and preventative care. This market is particularly important as the world faces the COVID-19 pandemic. It is imperative that components of these devices and test kits are reliable and of the highest quality.

Per the Rogers Corporation Website, Rogers “BISCO HT-800 Medium Cellular Silicone offers the lightness of foam with the enhanced sealing capabilities of sponge rubber.” In this post, we are going to dive a little deeper into this excellent material.

Silicone Rubber, a "Low Surface Energy" Elastomer, what does this mean?

Silicone is a high-performance elastomer with the ability to withstand extreme temperatures, both high and low. It also naturally repels, which makes it an excellent choice for a water seal or a moisture barrier. However, this also makes silicone tricky to bond to other surfaces.

IP Rated Enclosures: Venting Solutions

Sensors, controllers, and other electronic elements are being integrated into devices across virtually every industry. Many of these products are made for use in conditions where they may be exposed to extreme temperatures, rain, wind, dust, and moisture. (See application story about "smart" shipping pallets linked at the bottom of this post.) Designing such products requires that the container or enclosure holding the electronic components be completely sealed. Exposure to harsh elements could cause a product failure. 

Custom Die-cut Parts for Automated Assembly

Among numerous assembly options, automated assembly is often the method of choice for many of our customers. Automated placement is used for projects with very high volumes where precise placement is critical. Automated assembly can also significantly increase assembly speed and efficiency.

Marian designs and manufactures custom components to fit seamlessly into our customers’ automated assembly process. We can modify many different aspects of the final part and packaging from liner type, part spacing and orientation, and quantity of parts per roll.
