For High Frequency
Electronics

ANNOUNCEMENT:

Kayaku Advanced Materials has acquired SignalSeal from GVD Corporation

Uncompromising High-Reliability &

High-Frequency Conformal Coatings

Paratronix’s SignalSeal is a proprietary polymer that is deposited in ultra-thin and uniform layers on high-frequency or high-speed circuits, protecting these circuits from the elements without degrading performance. Meeting, and exceeding, a battery of industrial and military performance standards, SignalSeal is the premier conformal coating technology for protecting circuits to 100 GHz.

Withstands Harsh Environments

SignalSeal is an ultra-thin, pinhole free, conformal coating providing military grade environmental protection at a thickness of only 1 micron.

Maintains Signal Performance

SignalSeal exhibits electrical characteristics ideal for high-speed and high-frequency applications to 100 GHz with negligible impact on signal integrity.

Ideal for Delicate and Complex Structures

SignalSeal is applied using a contactless, room temperature chemical vapor deposition (CVD) process suitable for the most delicate structures and materials.

Provides Cost Saving Workability

SignalSeal enables easy part removal without the need to strip the coating first. A reapplication is all that is needed to ensure protection to the highest standards.

Learn How Conformal Coating Has Evolved for Critical Applications

A new breed of conformal coating allows for common and efficient mass assembly processes, military-grade ruggedness, and minimal impact on RF and high-speed digital performance.

Insertion Loss: Before and After SignalSeal Coating

In a study of the high frequency impact of SignalSeal, Rogers Corp. was contracted to perform a battery of tests on 50 Ohm microstrip transmission lines on 0.0047” thick Rogers RO4350B ™. Broadband testing to 50 GHz was performed on several samples of coated and uncoated samples and the insertion loss over length was analyzed and plotted. The graph shows a direct comparison of a SignalSeal coated and uncoated microstrip sample, which demonstrates negligible insertion loss impact across the full bandwidth of the test. Moreover, several microns of SignalSeal were used to coat the samples, which is many times the thickness typically used to coat production units.
