Fast and Accurate Deposit Internal Stress Determination

摘要

Internal stress in plated deposits is a common problem that unchecked may affect the coating functionality and cause distortions in electroformed items. Ability to determine deposit stress in real time offers the plater a tool for preventing rejects before they occur. A modified bent strip technique for conducting stress measurements directly in the plating tank, developed several years ago and proven in a number of critical applications, will be described and compared to the traditional spiral contractometer method.
