Bob Bob: Fortunately, you found this before you built-up a lot of product. Some thoughs and other drivel: 1 Use IPC-TM-650, Method 2.4.8 for copper peel with a Instron machine. Typical pad peel strength requirement for FR-4, 2 oz. copper is: 6 l

Don't sound proper. There is no specification. Pad peel strength test methods are: * IPC-TM-650, Method 2.4.21 for multiple solderings * IPC-TM-650, Method 2.4.8 for copper peel with a Instron machine. Typical requirement for Cu is: 6 lbf/in [1

The proliferation of tighter microvia densities and signal integrity requirements in printed boards within the electronics industry has revealed reliability concerns with microvia structures in high performance products. A number of IPC OEM member companies have approached IPC with examples of microvia failures in high-profile hardware that were not observed until after bare printed board fabrication, inspection and acceptance, including:

Smartphones and tablets require very high flexibility and severe bending performance ability of the flexible printed circuits (FPCs) to fit into their thinner and smaller body designs. In these FPCs, the extraordinary highly flexible, treated rolled-annealed (RA) copper foils have recently used instead of regular RA foil and electro deposited foils. It is very important to measure the Young's moduli of these foils predicting the mechanical properties of FPCs such as capabilities of fatigue endurance, folding, and so on. Even though the manufacturers use IPC TM-650 2.4.18.3 test method for measuring Young's modulus of copper foils over many years, where Young's modulus is calculated from the stress–strain (S–S) curve, it is quite difficult to obtain the accurate Young's modulus of metal foils by this test method.
