Hi CW, Larger chip caps can be susceptable to cracking, but mainly this is due to handling - flexing of boards is the main culprit (the part being mechanically joined at both ends to the board). PCB's usually flex easiest along one axis, and larger

Depending on the material, the etching can damage the dielectric. This can be manufactured but is difficult and expensive. Copper plating and other processes that require agitation are almost impossible.

Channel simulations are only as accurate as the models used to develop them. While we have seen much effort placed on printed circuit board (PCB) materials (copper finish, dielectric moisture absorption), other elements within the channel have been largel

Higher-speed signal transmission is increasingly required on a printed circuit board to handle massive data in electronic systems. So, signal transmission loss of copper wiring on a printed circuit board has been studied. First, total signal loss was divided into dielectric loss and conductor loss quantitatively based on electromagnetic theory. In particular, the scattering loss due to surface roughness of copper foil has been examined in detail. And the usefulness of the copper foil with low surface roughness has been demonstrated.
