In-Line Parylene Processing?
The phrase “in-line Parylene processing” is deceptive because it does not accurately describe the method in which Parylene (XY) is applied as a conformal coating. Some aspects of the traditional production line are relevant but without station-to-station regimentation of standard in-line manufacturing processes. A conventional factory production line incorporates a structure wherein the object being... Read More >>
Why Use an Automated Conformal Coating Spray Robot
A typical conformal coating selective robotic spray process consists of a programmable XYZ coordinate platform with a valve or valves attached to a controllable arm, depositing coating onto a printed circuit board in areas specified by the system programming. Technology varies between different platforms and valves, but essentially, they achieve the same result. The goal... Read More >>
Nanocoating vs Parylene
Although its basic component is remarkably small–-25,400,000 nanometers per inch–nanotechnology encompasses a growing, interdisciplinary field with an unlimited future. Nanowires and nanotubes are used in transistors for printed circuit boards (PCBs) and associated electronic assemblies. Bio-nano batteries, capacitors, LCDs and microprocessors represent just a few nanotechnology applications. Uses of Nanocoatings Conformal coatings protect electronic components... Read More >>
Conformal Coating for PCBs
Printed circuit boards (PCBs) electrically connect and power even the simplest electronic products. To function as designed, PCBs and their components – capacitors, resistors, etc. – require protection against operating problems caused by corrosive liquids, dust, physical shock and temperature extremes as well as the bodily fluids medical implants must endure. Conformal coatings are applied... Read More >>
5 Keys to the Conformal Coating Process
The conformal coating process requires careful administration to ensure successful implementation. Recognizing the unique properties of various conformal coatings is critical in selecting the most applicable coating to a project while meeting clients’ material and operational specifications. Regardless of the coating material and the component, these five fundamental procedures are essential in producing a good... Read More >>
Best Conformal Coating for Moisture
Conformal coatings are used in many of today’s advanced electronics to ensure product performs reliably and protect its functionality. While the coatings offer many beneficial properties, many printed circuit boards (PCBs), printed wiring boards (PWBs) and electronic assemblies rely on conformal coating protection against moisture. Depending on the end use of the product, PCBs or... Read More >>
Ideal Coatings for Medical Devices
Parylene is a polymeric material that is commonly applied as a conformal coating layer in electronic applications. Parylene conformal coatings are used to provide barrier protection from environmental elements and/or to provide dielectric isolation in charged conditions. They offer pinhole-free layers with low water permeability, high flexibility and high mechanical strength. While Parylene coatings are... Read More >>
Conformal Coating Facility Setup: General Requirements
If you are looking to apply conformal coatings in-house, there are several intricacies of the process can sometimes be overlooked. Given the solvents used in the spraying process, extraction is necessary. The necessary level of extraction will depend on regulations at the local, state, and federal levels. Thus, a comprehensive review of the relevant laws... Read More >>
Improving Biocompatibility with Parylene
As a biomaterial, Parylene offers numerous possibilities in the fields of biomedical implants, biophysical studies, biosensors and tissue engineering. For instance, biological microelectromechanical systems (BioMEMS) offer accurate, rapid medical diagnoses, copying standard laboratory services onto miniaturized devices that can be inserted safely into the human body. A problem limiting greater effective miniaturization has been finding... Read More >>
How Parylene is Applied Compared to Other Conformal Coatings
The generic name Parylene describes a distinct collection of polycrystalline and linear organic coating materials with innumerable applications. The essential basis of today’s Parylene N, p-xylene, was inadvertently synthesized at England’s University of Manchester in 1947. The filmy residue resulted after high-temperature heating of compounds of toulene and the xylenes polymerized into para-xylene. The substance immediately demonstrated an exceptional capacity for generating... Read More >>
