Technical Papers

Parylene - General

Solvent Resistance of the Parylenes

Study reviews the effects of a wide variety of organic solvents on Parylenes N, C and D.

Controlling Parylene Process Quality

This paper identifies and describes quality issues related to use of Parylene vacuum-deposited conformal coating in the protection of electronic components and assemblies.

Parylene - Medical

Challenges with Prefilled Syringes

In this article, SCS concisely describes the applications and advantages of Parylenes, a series of inert polymeric coatings. In the prefilled syringes sector, Parylenes serve dual purposes being both a effective barrier material and highly lubricious coating.

Coating for Consumption

Ingestible medical devices offer a convenient, non-invasive method of delivering therapeutics, enabling diagnostics procedures, or performing imaging tasks. However, ensuring that the sensitive electronics within the device are protected is a challenge. This article will highlight a coating technology that is being used to guarantee such protection is provided.

Advances in Adhesion Solutions for Medical Applications

As electronic devices become ever smaller, their performance in many different types of operating environments has led many device packaging companies into the world of conformal coatings. Adhesion of such coatings to the intended substrate surfaces is one of the most important features of a coating’s effectiveness.

A Look at Parylene Coatings in Drug-Eluting Technologies

The continued success of drug-eluting stents relies heavily on little-known technologies. Parylene, for example, could have far-reaching applications.

The Truly Conformal Coating

The multi-property, biocompatible polymer Parylene has proved itself as having an unsurpassed role in medical coatings.

Parylene – Advanced Polymers for Medical Devices

While the demand for reliability and safety has always been at the forefront in medical device design, the challenges of minimally invasive and micro/nano devices require new and different packaging solutions.

New Development in Parylene Technology for Medical Electronics Advancement

Biostable packaging, protection and reliability of various medical electronic components and devices (e.g. retinal implants, implantable cardiac defibrillators, neurostimulators pulse generators, RFID implants, equipment, hearing aids, ingestible sensors/transmitters, and implantable radiation dosimeters) are becoming more challenging due to their long-term performance requirements.

Parylene - Electronics

Protecting Downhole and Platform Electronics

Oil companies must focus on cost savings to be profitable. A number of electronics used for the exploration, drilling, processing, and delivery of oil and gas operate in some of the harshest environments ever seen.

Protecting Modern Wafer-Level Packages

The demand for smaller sizes and lighter weights in consumer electronic devices is feeding the demand for continued package miniaturization.

Protection for Complicated SMD Assemblies

Most common conformal coatings actually can hurt, not protect, delicate and dense PCB assemblies. Parylenes are deposited differently, and offer EMS providers another option for electrical/dielectric, chemical and mechanical protection. Parylene HT proves promising for miniaturized assemblies.

Parylene as a Suppressant for Tin Whiskers Growth on Printed Circuit Boards

With the implementation of RoHS directives, pure tin plating is replacing lead in the tin-alloy used in the printed circuit boards and other worldwide electronics. Although use of tin provides a safer environment for electronic manufacturers and helps meet the regulatory requirements, it is known to form tin whiskers, odd shape eruption and dendrites that cause printed circuit boards or devices to fail.

Parylene Applications - Automotive

Parylene Rises to the Challenge

Because the failure of one component could mean an entire system failure, OEMs rely on coatings such as Parylene – an inert, conformal, polymer coating – to protect electronics and other devices and prevent failures that add to warranty costs.

An Advanced Material for Enhancing Reliability and Protection of Automotive Electronics and Other Components

With the increasing trend for better and safer products, protection and reliability of various electronic components (pressure and temperature sensors, PCB’s, MEMS and fuel cell components, etc.) used in the automotive industry are critical as they are becoming smaller, more complex and provide life of vehicle performance in harsh environments.

Parylene Applications - Military/Aerospace

Parylene Coatings Can Protect COTS Electronics in Aerospace and Defense Applications

Financial considerations show that the use of COTS electronics for military applications will continue growing, so designers should protect them from heat, moisture, and radiation. The challenge is how to protect devices originally designed for non-military use without additional enclosures.

Parylene Applications - Ferrites

Parylene Conformal Coating Benefits Coil Winding Processes

Small forms, spindles, ferrites and miniature wire-wound electric motor parts can benefit from the protection of a thin, vacuum-deposited coating.

Conformal Coatings - General

Advanced Coating Technologies for Lead-Free Solders

It has been shown that various conformal coating materials can help mitigate the damage done by tin whiskers. Coatings do not prevent the growth of whiskers, but studies have shown that some coatings do slow down or retard the formation.

Alternatives in Conformal Coating

Conformal coating of printed circuits and circuit assemblies is often required for protection against environmental concerns such as moisture, chemicals and damaging vapors. Such coatings also prevent disruption and circuit damage that could be caused by inadvertent shorting between conductors.

Ionic Contamination Testing Technology

Advances in Ionic Testing

Since the birth of the PCB, there has been a need to test for residual ionic contamination, which can lead to corrosion and dendrite growth. Whether on bare boards or finished assemblies, contamination can cause current leakage across insulating surfaces — resulting in shorts. This article explains advancements in ionic cleanliness testing, including heated dynamic ionic contamination test systems and their benefits.

Influences on Contamination Testing

The Ionograph was designed to be a simple, fast and accurate means of testing for ionic contamination as compared to the expensive, time consuming, and highly technical alternative of chromatography. However, the accuracy of the instrument is dependent on the condition of the Ion Extract Solution.


Parylene Conformal Coatings for the Oil & Gas Industry

Originally published by Oil & Gas Journal, this concise 30-minute webinar offers viewers an opportunity to learn more about how Parylene coatings are applied, their features, and the value they add to devices and components, including excellent chemical and moisture barrier properties, high dielectric strength per unit thickness, excellent thermal and UV stability, and low coefficient of friction. As materials and applications continue to advance and operating environments become more harsh, Parylene conformal coatings enhance the performance of oil and gas technologies.
