The bottom line is: non-functional pads are not required in order for a PCB to be fabricated properly, but the PCB will not necessarily fail if you keep them either. Some guidelines state to always remove all non-functional pads. Personally, I prefer to keep the NFPs on a simpler design...
The need for nonfunctional contact pads at internal layers of multilayer printed circuit boards (PCB) is still under discussion. Published papers argue on both sides of the issue [1–4]. In the present work, various perspectives regarding the utility of nonfunctional contact pads in electronic ...
Three pins on this BGA part are non-functional and have no connects. Frequently, those three non-functional pads are lifted off the board during BGA part removal. The pads are not replaced prior to installation of the new BGA part. Can these boards still be said to meet Class 3 with the...
As a 15+ circuit designer, I can add that there are major advantages to having the non-functional pads removed. First is what we refer to as 'via damage' - in a multilayer PCB board the through-hole via is a multilayer constraint and especially under high-density BGAs the ground and po...
The power supply designer is the person who best understands the technical details and functional requirements of the supply within the final product. He or she should work closely with the PCB layout designer on the critical supply layout from the beginning. ...

Through the optimization of functional materials and device design, the E-skin ...
A lot of issues arise during thePCB designprocess. One of such is the possible problem from PTH and NPTH. It is necessary to comprehend the differences found between these through hole technologies in order to achieve a functional circuit board. Knowing the difference between these two will help...
Density functional theory (DFT) calculations indi- cate that the broken space inversion symmetry, because of cationic asymmetry and the presence of Mn3 + /Mn4 + mixed valency origi- nating in the interfacial polar discontinuity, give rise to the observed behaviour. This discovery ...
