Pull-Tabs, Extended Liners, and Split Liners for Ease of Assembly

Posted by Katie Sullivan

Sep 9, 2020 9:34:31 AM

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 manufacture. 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.

Corona Treatment of Silicone Elastomers and Plastic Films

Posted by Katie Sullivan

Aug 12, 2020 8:30:00 AM

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.

The Best Thermal Pad for Your Design

Posted by Katie Sullivan

Jul 29, 2020 9:30:00 AM

Thermal gap pads 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.

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.

3M Die-Cut Tapes

M arian die cuts millions of components containing 3M tapes. 3M die-cut tapes are used in countless applications across many industries. 3M offers one of the most innovative portfolios of tape products in the world including double-sided tapes, single-sided tapes, adhesive transfer tapes, 3M™ VHB™ tapes, and double-sided foam tapes. While 3M tapes can be applied utilizing rolls of material, there are many scenarios where a die-cut component can greatly improve placement efficiency and accuracy.

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.

4 Insulating Materials for use in EV Batteries

Posted by Katie Sullivan

Aug 27, 2019 9:00:00 AM

Improvements are being made to the lithium-ion batteries used in electric vehicles. Car makers are developing more powerful lithium-ion batteries that have increased range and charge more rapidly. Along with these improvements, enhancing safety is 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
  • light weight
  • electrically and thermally insulating
  • flame retardant
  • can be die-cut and laminated with PSA
