| Electronic Package Designs Running Hotter
Heat Transfer and Thermal Conductivity are Critical Factors...
|
|
| As industry demands that electronic packages continue to become smaller and more compact, the need to address the heat generated by these small devices continues to increase. Dissipating this heat and removing it from the unit is a key factor in the performance and longevity of many devices. ITW Insulcast manufactures a number of materials that provide superior heat transfer and thermal conductivity characteristics to meet these demanding requirements. |
These materials draw heat out from the unit where it is not wanted and transfer it to the outside where it can be dissipated. Thermally conductive materials that come in a variety of viscosities, mix ratios and hardnesses are available to meet most processing requirements. |

| Speciaized Materials, Specific Applications
High Voltage Power Supplies...
|
|
| Encapsulating high voltage power supplies and equipment presents its own technical challenges that need to be overcome with highly engineered potting and encapsulation materials. High voltage equipment produces heat transfer, corona, vibration and adhesion issues that are unique to the electronics industry. |
ITW Insulcast has long been a leader in this demanding industry. Our selection of specialized materials designed to meet these particular challenges has been used for many years by some of the top names in the industry. Our product selection continues to evolve in order to meet the ever-changing requirements of this fast paced industry. |

| Eliminate Cracking and Stress Issues
Silicone-Epoxy Copolymer...
|
|
| Our unique silicone-epoxy copolymer is widely used to successfully address the problem of cracking during thermal cycle stress. This material also exhibits excellent primerless adhesion to most substrates. In a number of instances, this family of copolymers was the only material passing all test parameters.
In one case, the use of this copolymer not only allowed a leading manufacturer to keep one of its primary operations
|
that was slated for closure open, but its use resulted in that firm cementing its position as the dominant supplier in its field.
Copolymer chemistry allows for decreased overall cycle time as well as superior characteristics that address unique problems in critical electronic applications resulting in lower reject rate and superior performance.

| Volume Production Materials
Insulcast 116FR
|
|
Insulcast 116FR is a one-to-one mix ratio (weight or volume) epoxy potting and casting compound designed for production use. The convenient mixing ratio of the material makes it ideal for production line mixing as well as automatic dispensing. Insulcast 116FR is among the safest epoxy compounds available.
|
It appreciably reduces the risk of eye, skin or respiratory problems generally associated with the use of epoxies.
Insulcast 116FR is U.L. recognized under file E86165 and meets the flammability requirement of 94 V-0.
