What Solvent Breaks Down Parylene?

Posted by Sean Horn on Fri, Mar 3, 2017

While parylene provides a reliable, versatile conformal coating, it can require removal.  When circumstances necessitate removal of liquid coatings – acrylic, epoxy, silicone or urethane – a wide range of chemical solvents can be used to detach the film from the underlying substrate.  No single chemical material/process is equally successful for all uses, but solvent […]

Is Parylene Safe?

Posted by Sean Horn on Fri, Aug 12, 2016

Application of parylene’s xylylene monomer employs a chemical vapor deposition (CVD) process implemented under a vacuum.  Unlike wet coating application methods – brushing, dipping, spraying, etc. – parylene CVD is not line-of-sight.  Because the vaporous monomer envelopes all sides of the assembly being coated, appropriate process control allows vacuum deposition of an entirely conformal
