Tubing and Parylene Coating
Tubing is designed to contain or transport substances, typically liquids or gases, and is often constructed of plastic, metal and sometimes glass. When many people think of tubing, they envision its use in construction or mechanics, which is often specified by its material of construction as well as its dimensions, specifically OD (outer diameter) and...

Moisture Protection of Parylene
Conformal coatings play a vital role in safeguarding the performance of advanced electronics, like printed circuit boards (PCBs), ensuring their functionality under demanding conditions. A key focus of these coatings is shielding PCBs from moisture damage, which can stem from various sources. Exposure to acid rain, harsh solvents, air pollutants, chemicals, fog, high humidity, intermittent... Read More >>
How to Avoid Bubbles in Conformal Coating
Bubbles and foam are two of the leading causes of failure during conformal coating inspections. Bubbles cause voids in the coating, leaving areas of the substrate exposed to potential contaminants. Therefore, it is important to understand what causes bubbles to form and the steps to take to prevent them. 5 Common Causes of Bubbles in... Read More >>
Parylene-Enabled Flexible Prosthetic Devices: A Review
The flexible electrode and coil components utilize Parylene C as both a coating and structural material. Parylene C is selected for its pinhole-free nature, uniform deposition, low water permeability, flexibility, mechanical strength, ISO 10993 biocompatibility and USP Class VI rating. Inductive coupling of a pair of coils is a promising technology for wireless power and... Read More >>
Conformal Coating Service: What to look for?
Once the decision to outsource conformal coating has been made, the next step is to evaluate and select a suitable vendor. Consider these important factors when selecting a coating service provider: Experience Establishing robust procedures and processes for conformal coating is a task that requires both time and experience. While numerous new vendors may assert... Read More >>
Parylene for Defense Applications
What is Parylene? Parylene is a conformal protective polymer used for coating, first postulated by Michael Szwarc in 1947. His early experiments involved the decomposition of the solvent p-xylene. His worked proved that when the vapors of the p-xylene reacted with iodine, para-xylyene di-iodide was the only resulting product. The reaction produced only a low... Read More >>
Using Conformal Coating to Prevent Reverse Engineering
Conformal Coatings are used regularly in an attempt to cover technology designs on printed circuit boards (PCBs). Normally, this is done by using a pigmented conformal coating which obscures the components below the conformal coating material. This does effectively hide the circuit board and components initially. However, the relative success of this method is dependent... Read More >>
Cleaning Methods for Conformal Coating
Cleaning the substrate is an essential element of preparation for conformal coating, and here are several key reasons why: Although taking the steps to assure that substrate surfaces are clean increases production time and expense, the consequences of applying conformal coatings to contaminated components is far costlier and more time-consuming in the end. In addition,... Read More >>
Parylene’s Optical Properties and Performance
Parylene is a reliable, protective, conformal film that safeguards printed circuit boards (PCBs), similar electronic assemblies and other products. Parylene generates advantageous optical properties for a wide range of uses, including artwork/museum artifacts, cameras/sensors, computer touchscreens, healthcare/medical devices, light-emitting diode systems (LEDs), lenses and optoelectronic components. It should be noted that while the thinnest Parylene... Read More >>
Parylene Conformal Coatings and UV Light
Parylene has numerous outdoor applications. However, a major drawback of most Parylene types is limited resistance to direct contact with UV radiation. Daylight is the most common source of UV light. Prolonged exposure to its high energy radiation can cause objects extensive surface damage and lead to eventual malfunction of coated products. This is a... Read More >>
