3M™ Thermal Interface Tapes Help to Improve The Life of an LED Lighting Application

Challenge

An LED lighting manufacturer came to us seeking ways to improve the lifetime performance of LED bulbs within their fixtures.

This company was previously using a thermal grease to help transfer the heat being created from the bulbs away from the enclosure.

The problem with using a thermal grease is that it can get quite messy, and unless you are used to working with thermal grease, it is hard to apply and evenly distribute.

Solution

SRP recommended a thermal interface material to dissipate the heat in the fixture. This material is designed to provide a heat transfer path between heat generating components and cooling devices.

We also suggested a microcellular urethane to prevent environmental contaminants from entering the product. We were con dent this was the perfect solution to prolong the life of the LED bulbs.

Results

Our customer was pleased that their thermal-management product was now higher performing and superior to its predecessor. The elimination of the thermal grease resulted in a much simplified assembly process as well.

These cost saving improvements reduced assembly time immensely, while providing more efficient distribution of heat throughout the application.

Switching To A More Cost Effective Material, While Maintaining Optimum Performance

Challenge

This electronics manufacturer was using a silicone interface pad on a heat sink for a small electronics application. The purpose of the interface pad is to provide a preferential heat transfer path between heat generating components to keep the product from overheating, which will eventually damage the product and rendering it useless.

The challenge, however, was not in the functionality of the product, but in the expenditure of the application. Our customer was looking to be more cost effective with their products.

Solution

After understanding the temperature specifications of the application, SRP realized that the performance of the silicone adhesive they were currently using was a lot more than what was required.

Our solution was to switch to the 3M 5571 Acrylic Thermal Interface Pad to be more cost effective, while continuing to maintain the same performance of the Silicone Pad.

Results

After thorough testing of the new 3M 5571 Acrylic Thermal pads, our customer found that this material was more than enough performance to keep their products safe from the heat at a fraction of what they were spending with the silicone interface material.

Utilizing a Sealing Gasket to Keep Unwanted Environmental Debris From Damaging a Telecommunications Cabinet

Challenge

This company was seeking a product for their telecommunications cabinets. These cabinets are built in two separate sections, and then the sections are pieced together at the end of assembly to form one enclosure.

For this, they needed a gasket that would create a seal between the two sections that wouldn’t affect the integrity of the cabinet.

Solution

Closed cell sponge rubber with a rubber-based adhesive was the perfect candidate for this application for multiple reasons.

Since the application was non-critical, the material did not require specific properties other than sealing out water, rain, and dust. Also, considering the seal will never have to be broken, compression set was a non-factor.

Results

A sponge sealing gasket is all that was needed to protect the cabinets from the outside environment. Simple solution to a pesky issue. The combination of materials, coupled with our manufacturing process, allowed us to offer them the highest performing, lowest cost solution.
