A properly formed solder connection is stronger than the underlying copper to laminate bond. Measuring pad peal strength: IPC-TM-650, Method 2.4.21 for multiple solderings, use Method 2.4.8 for copper peal using an Instron machine. Typical requirement for Cu is: 6 lb (force)/in [106 kg (force) /m].
