The Importance Of Printed Circuit Boards

Moisture absorption occurs when the material is exposed to high humidity or water. Both resin and reinforcement can absorb water; Water can also be soaked by capillary forces through openings in materials and along the reinforcement. The epoxies of FR-4 materials are not too sensitive, with an absorption of only 0.15%. Polyimids and cyanate esters, on the other hand, suffer from high water absorption. Absorbed water can lead to significant degradation of important parameters; It affects tracking resistance, breakdown voltage and dielectric parameters. Printed circuit boards are synonymous with electronic products. You have used one if you have ever owned or used an electronic product. By definition, a printed circuit board includes a separate circuit board that electrically connects elect
