Cost of Parylene Dimer

Posted by Sean Horn on Fri, Apr 07, 2017 @ 07:32 AM

Perhaps the most reliable of the conformal coatings, parylene (para-xylylene di-iodide) is also one of the more expensive coating options.  Production costs typically encompass three primary expense categories -- raw materials, labor, and lot volume.  Of the three, labor expenses are generally the most costly, but raw materials can add significantly to production overhead; materials’ costs can be largely attributed to the raw parylene dimer required to make conformal coatings.

How much does parylene cost?

Posted by Sean Horn on Wed, Aug 29, 2012 @ 03:15 PM

Everyone loves the barrier properties of parylene.  The resistance to solvents and moisture, incredible dielectric strength, and the completely uniform coverage are enough to make any engineer squeal with delight.  The question that immediately follows is, “How much does parylene cost?” 

There are a couple different factors that go into decided parylene cost.  One of these factors is the material cost.  Parylene dimer can be anywhere from $100 to $10,000+ per pound depending on the type and quality.  Other raw materials, such as the cleaning materials and adhesion promotion mediums, also factor into the materials costs for parylene.

How Parylene Cost is Determined

Posted by Sean Horn on Mon, Apr 16, 2012 @ 03:34 PM

Parylene is often priced out to be one of the more expensive conformal coating options.  After a quick look at some of the cost factors, it will be easy to see why.  Three of the main factors that influence parylene cost are raw materials, labor, and lot volume. 

 Raw Materials – Parylene Dimer and Adhesion Promotion

 Parylene dimer is the raw form of parylene.  It is the solid inserted into the machine that is broken down through the deposition process.  Cost for parylene dimer can be anywhere from $200 to $5,000 per pound depending on the different type of dimer.  A typical coating run is around a pound of dimer.

The Parylene Deposition Process

Posted by Sean Horn on Thu, Mar 22, 2012 @ 09:00 AM

The Parylene Deposition Process

 Parylene coating is applied through a vapor deposition process onto the substrate or material that is being coated.  Depending on the coating type and required thickness, typical parylene deposition rates are about .2/mils per hour, so machine runs can vary from as little as 1 hour to over 24 hours.  The process begins with raw dimer in solid state (these are:  Parylene C, Parylene N, Parylene D, Parylene AF-4, or other variants) being placed into a loading boat, which is then inserted into the vaporizer.  The raw dimer is heated between 100-150º C.  At this time, the vapor is pulled, under vacuum into the furnace and heated to very high temperatures which allows for sublimation and the splitting of the molecule into a monomer.   The monomer gas continues to be drawn by vacuum one molecule at a time onto the desired substrate at ambient temperatures in the coating chamber.  The final stage of the parylene deposition process is the cold trap.  The cold trap is cooled to between -90º and -120º C and is responsible for removing all residual parylene materials pulled through the coating chamber.
