Managing the Thermal Resistance for Critical Thermal Management Applications from AI Technology

Thermal management is becoming one of the critical design and manufacturing considerations in electronic devices that generate heat. In some solar applications, the ability to channel heat to the designed power generation mechanism is becoming an important consideration in balancing the costs of goods being made. There are two main categories of thermal interface materials (TIM): adhesive and non-adhesive.

Non-adhesive TIM are used in electronics and other applications to provide an intimate interface between contact surfaces to reduce thermal impedance.  These materials include thermally conductive greases, gels and thermal pads. In the manufacturing environment, dry thermally conductive phase-change pads can be applied with pick-and-place equipment whenever applicable. For pads that are tacky they can be applied manually.

Traditionally well-engineered thermal grease and gels empirically provide for the lowest thermal resistance for a majority of applications. The more prevalent use of phase-change pads is primarily based on the perceived predictable and repeatable performance because the pads have the same size and thickness before they are applied. In recent years the low melting metal-alloys that melt at temperatures below the operating temperature of the interface have also been used. In either case mechanical fasteners must still be part of the device or application construction.
In some of the less critical TIM applications, compressible thermal gaskets or pads are also used. Normally, these applications required periodic removal of the assembly for inspection, repair and maintenance operations. In some cases, the tolerance between various components or portions of the heat-generating sources vary in height. Again, strong mechanical fasteners are required to provide substantial compression to remove as much of the interfacial gaps and voids as possible.  AIT has developed compressible phase-change thermal pads [1]  that have been proven to have the same thermal resistance as the best thermal greases.

For those applications that do not or cannot use a mechanical fastener, the TIM must double as an adhesive and form a thermal interface bond between the heat-generating device and the dissipating structure. AIT has pioneered many thermal adhesives for long-term reliability with flexible stress-free bonding since its inception in 1985[2]. One of the patented applications is the use of thermal pressure sensitive adhesives that are further cured for additional bond strength "in-situ" using the heat generated by the device.

Thermal interface resistance is known to change over time because of either TIM aging or stresses induced during thermal cycling and shock. The paper in the link below provides more detail of important management aspects such as reliability issues.

Twenty Years of Technological Development Position Remtec as Leader in Metallized Ceramic Substrates and Packages

Remtec Inc. is celebrating its twentieth year as a company specializing in manufacturing a variety of ceramic packaging products for both commercial and military electronics.  Acknowledging this anniversary, Remtec President Nahum Rapoport commented:  “Over these years, we have focused on design, development and manufacture of reliable, cost effective products providing a multitude of ceramic packaging solutions that meet the changing and demanding needs in DC power electronics, RF / microwave packaging and optoelectronics.”

The first of Remtec’s technological breakthroughs came shortly after it’s founding in 1990 in developing its core manufacturing technology, PCTF®, based on combining Plated Copper and Thick films, and a patent for this technology and manufacturing process was issued in 1994.  Since then PCTF® technology has become the foundation for Remtec’s business and has undergone continuous development and advancement.

Initially, PCTF® was developed for high circuit density and high power in DC electronics. In 1997, development of unique metal filled via holes and wraparounds allowed Remtec to also enter the high frequency RF market, offering leadless ceramic SMT substrates and packages for direct PCB mount with improved thermal and electrical performance. In 1998, in order to meet high reliability requirements, Remtec developed a line of highly integrated hermetic SMT ceramic packages, both leadless and leaded, incorporating passive components and multilayers for military, aerospace and industrial applications.

With broadening product lines and fast sales growth, Remtec recognized the need for higher volume production and integrated manufacturing. In 1999 Remtec moved to a new manufacturing site, acquired a plating company and installed a fully automatic, cassette-to-cassette screen printing line.  As a result, today Remtec is a fully integrated design and manufacturing company with state- of -the -art equipment operating in a 30,000 sq. ft modern facility.

The emphasis on new process and product development has continued in this decade. Improved etched conductor capability combined with thermal vias and integrated copper heat sinks allowed Remtec to penetrate the high power packaging market up to mm wave frequencies.

In 2007 Remtec entered the laser submount market introducing its new high performance submounts with Zero Pullback™ metallization of 50 micron thick copper for high power laser diodes.  In 2009, Remtec added a new capability: an innovative, low cost gold tin finish for high power laser diode submounts.  Remtec now offers this industry a reliable single source for submounts based on PCTF® technology with Zero Pullback copper metallization and an economical gold tin finish on BeO and AlN.

Remtec, a ROHS compliant and ISO 9001:2000 registered company, operates two manufacturing facilities totaling 30,000 sq. ft. in Norwood, MA.  Remtec provides custom and semi-custom packaging solutions with PCTF® metallization on Alumina, BeO, AlN, Barium Titanate and Quartz for DC power electronics, optoelectronics and MW/RF components and modules.

Vectra® LCP From Ticona Gives Dimensional Stability To Housing In Award Winning Samtec BullsEye™ System

Samtec Inc., a worldwide manufacturer of a broad line of electronic interconnects, has specified a glass-fiber reinforced Vectra® liquid crystal polymer (LCP) from Ticona Engineering Polymers for an injection molded housing used in its award-winning BullsEye™ test point system.

"The decision to use Vectra E130i was simple — it provides the needed precision, dimensional stability and mold flow that Samtec requires in thin-wall electronic connectors," said Jon Hoffman, Advanced HDR Development Engineer, Samtec. "We've had a lot of success with it so we didn't need to spend much time considering alternatives."

Samtec’s BullsEye, named the DesignVision winner at DesignCon 2010, is a high-density, high-performance, low-cost solution that eliminates the need for expensive radio frequency (RF) connectors on production boards. An inexpensive microwave cable adaptor (RF25M) attaches to the existing SubMiniature version A (SMA) type RF connector on the test equipment, then to a plastic housing (CCH) on the board via a compression tip with locking features. A conductive elastomeric inside the plastic housing allows for the ground to transfer to the board in the same manner as it would in an SMA. The plastic housings use the exact footprint as an SMA, but cost much less. Ganged versions can be used to increase the density.

The BullsEye unit contains a Vectra LCP housing that forms the heart of the RF connector. The Vectra LCP workhorse, 30 percent glass filled E130i, was Samtec's material of choice because it offers high-heat resistance, good dimensional stability and good flow.

Vectra LCP is well suited for electrical and electronic components.
"Its high flowability allows it to fill long, complex flow paths in molding and create thin-walled parts having outstanding dimensional accuracy, both of which are essential in creating high-precision parts like the housing that Samtec used in the BullsEye," said Ed Hallahan, marketing manager — Vectra LCP. "Vectra LCP also gives electronic component manufacturers excellent dimensional stability and a low coefficient of thermal expansion, so they can consistently obtain dimensional accuracy with virtually flash-free parts at an economical cost."

Vectra E130i is 30 percent glass filled and offers the following material characteristics:

  • High temperature capability for easier flow and quicker cycle times, making it suitable for applications where very thin walls are required
  • UL 94 V-0 listed at 0.20 millimeters thickness in natural and black
  • Relative-Temperature-Index (RTI), according to UL 746B: Electrical 464 degrees Fahrenheit (240 degrees Celsius), Mechanical 464 degrees Fahrenheit (240 degrees Celsius), Mechanical with Impact 428 degrees Fahrenheit (220 degrees Celsius) at 0.75 millimeters
  • Inherently flame resistant without additives
  • Halogen-free  

"In choosing the material for the BullsEye housing, we quickly went with what had worked in the past," said Samtec's Hoffman. "We knew Vectra would work and that Ticona wouldn’t let us down with quality or deliveries. This confidence saved us time in getting the product to market.”
