Not completely understood, electrically conductive tin whiskers are crystalline structures between 1-2 millimeters (mm) that can grow from surfaces where tin is used as a final finish; surfaces finished with electroplated tin are particularly susceptible to whisker growth. Although their occurrence was originally documented during the 1940s, no real solution has yet been devised to […]
Ruggedized products are conceived for use in severe conditions, environments where excessive moisture or dryness, extreme temperatures, high levels of vibration, wind, or lack of atmosphere are the rule. Internal components of these specialized products require the same degree of ruggedization as exteriors.

Parylene’s benefits as a conformal coating are well known. It resists heat, cold, moisture, and pressure; salt spray, electricity, and solvents can’t permeate it. And while these attributes of parylene contribute to the conformal coating’s appeal, they also present distinct challenges, particularly in regards to parylene removal, rework, and repair.
