NASA conformal coating

NASA-STD 8739.1 is the Workmanship Standard for Polymeric Application on Electronic Assemblies, which describes NASA’s technical requirements, procedures, and documenting requirements for staking, conformal coating, bonding, and encapsulation of printed wiring boards and electronic assemblies.  Included are requirements which establish the responsibility for documenting, fabrication, and inspection procedures to be used for NASA work including supplier innovations, special processes, and changes in technology.  NASA-STD 8739.1 was initially released in August of 1999, with improvements and minor changes to the standard in recent years.  The current up-to-date revision is NASA-STD 8739.1A with Change 2.

Conformal Coating Standards: Meanings and Uses

Posted by Sean Horn on Tue, Aug 14, 2012 @ 07:38 AM

The Conformal Coating Standards that currently exist can be considered from two points of view. First, there are the standards that are used by the manufacturers of conformal coatings to qualify the products, whether that is done by self-certification or completed by independent testing. Second, the standards are a method for users to determine the quality of the conformal coatings they are considering to select.

Conformal coating facility: Equipment required

Posted by Sean Horn on Mon, Aug 13, 2012 @ 09:26 AM

Last time, we discussed the general requirements necessary to open a conformal coating facility.  Now I will discuss the equipment that is required in order to have a properly operating facility.

Typical Conformal Coatings Used

Posted by Sean Horn on Thu, May 10, 2012 @ 08:59 AM

Different conformal coatings have a wide range of uses throughout many different industries.  While originally founded for the electronics industry, because of the benefits of using conformal coatings, it has branched into many other fields most notably medical, automotive, and LED.

 Medical Conformal Coatings Used

 While all conformal coating types can be used for different applications, for many medical devices, parylene is the way to go.  Because parylene is biologically inert, FDA approval of parylene coated devices is well-documented. The coatings comply with USP Class VI plastics requirements and are MIL-I-46058C / IPC-CC-830B listed.  Another benefit for medical devices such as stents and catheters is that parylene is entirely conformal, meaning that component configurations with sharp edges, points, flat surfaces, crevices or exposed internal surfaces are coated uniformly without voids or pinholes.
