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.

Conformal Coating Process – Phase 1 – Prior to Parts Arrival
Once we receive a purchase order from a customer, all of the pertinent information such as drawings, specifications, and special instructions are given to the quality department from our marketing team to create custom work instructions for that particular part. If the material to be used has not yet been determined, we work with the customer to determine the best material for their application.
WHAT ARE TIN WHISKERS
Tin whiskers are electrically conductive, crystalline structures of tin that sometimes grow from surfaces where tin (especially electroplated tin) is used as a final finish. Tin whiskers typically grow from lengths of 1-2 millimeters (mm) but have been observed to lengths in excess of 10 mm. Electronic system failures have been attributed to short circuits caused by tin whiskers that bridge closely-spaced circuit elements maintained at different electrical potentials.

How to get Repeatable Conformal Coating Thickness
Measuring your conformal coating thickness is one thing, however making it a reliable and repeatable thickness is something else all together. There are three main ways of conformal coating application where a repeatable thickness can be obtained, however, a fair degree of training and skills are needed to achieve this.
