mmWave Radar Design Enhancement with TechFilm B-Stage Adhesives

Posted by Dan Griffin on Oct 1, 2019 10:00:00 AM

Millimeter-wave (mmWave) radar technology has emerged as an accurate and cost-effective approach to motion sensing and control.  Resin Designs’ TechFilm B-Stage Epoxies (electrically conductive and structural) have been enhancing the performance of these devices.  With their precise bond line thickness and placement accuracy, the B-stage epoxy films play critical roll in ground plane formation and adhesion of patch antenna to power boards.   The technology has been front and center in the automotive arena from basic safety innovations like back up and side sensing devices to full autonomous driving development. As mmWave devices increase in number within an automobile, a number of key factors are driving development including:

5 Advantages of Cationic Epoxies

Posted by Dan Griffin on Aug 19, 2019 10:00:00 AM

Cationic and free radical are the two most popular mechanisms for UV adhesives. Approximately 93% of the UV market is in free-radical chemistry while cationic has about 7%. Although a minority of the market, cationic adhesives provide strategic advantages over traditional free-radical acrylate chemistries. These advantages are detailed below.

All You Need to Know About B-Stage Epoxy Films

Posted by Dan Griffin on May 2, 2019 10:13:13 AM

B-stage epoxy films for clean reliable bonding/thermal and electrical conductivity

Most of us are familiar with epoxy adhesives and coatings, especially those of us within the electronics and medical device industries. We have all seen and often used two-component liquid epoxies. They are provided in syringes or pails for dispensing as adhesives, sealants, gaskets, and coatings. There is, however, a lesser known relative that can be cleaner, more consistent, environmentally friendly, and capable of unique properties such as thermal and electrical conductivity. It is known as B-stage epoxy film

How to Increase Flowability & Thermal Conductivity of Your Potting Material

Posted by Kris Hanson on Dec 20, 2018 9:38:39 AM

Thermally conductive silicone products are widely used in the electronics industry to radiate heat away from locales for component survivability while maintaining optimum operating temperatures. For potting and encapsulation applications, circuit board engineers typically specify flowable products that will quickly surround the components after dispensing and become solid at room temperature within an hour or less.

7 Benefits of Pre-Cured Pads in Thermal Interface Applications

Posted by Kris Hanson on May 15, 2018 10:00:00 AM

Concerned about the long-term reliability of dispensed, non-curing thermal interface solutions? What about cracking and pump-out that increase thermal resistance after aging and thermal shock? These are just a few of many important reasons to consider using pre-cured pads as a thermal transfer medium between a heat spreader and electrical components over wet-dispensed products that are prone to failure over time as in the example provided below.

5 Important Reasons Why You Should be Mindful of Glass Transitions Temperatures When Selecting an Epoxy Adhesive

Posted by Resin Designs Editor on Nov 8, 2017 11:03:00 AM

Unlike thermoplastic alternatives such as hot melt adhesives, cured thermosetting epoxies will not re-flow or melt when heated. Instead, epoxies will undergo a transition from a hard-rigid state to a more pliable, rubbery state. The temperature range during which this transition takes place is known as the glass transition temperature, Tg.

How to Select the Right Thermal Interface Material

Posted by Kris Hanson on Sep 18, 2017 1:00:00 PM

A common limiting factor in the advancement of electronics systems is heat. The need to manage heat removal with a cost effective solution is a significant driver in the design of many electronic devices. Thermal interfaces play a huge factor in a device’s operation both in performance and reliability. Thermal interface materials (also referenced as a “TIM”) are mostly thermally conductive, ceramic-filled systems with organic or silicone binders added to make them flowable for dispensing and processing. These materials can be used to accelerate heat dissipation and give the cost-effective method engineers need for flexibility to reduce overall size of the package.

The Various Methods for Curing UV Adhesives

Posted by Tim Desmond on Aug 31, 2017 11:00:00 AM

A majority of manufacturers, including Resin Designs, understands that new technology is frequently misunderstood. For example, let’s circle back to 15 years ago when suppliers of LEDs believed that this light source could cure UV adhesives more cost efficiently than mercury bulbs, metal-halide bulbs and electrodeless bulbs. Manufacturers also believed the following:
