Hi MGL, Couple things to ask, have the boards recently been changed to Rohs builds? STD FR4 to High TD Laminate. Check the stack-up the board houses are using. Just about all Rohs laminate has Resin starvation issues when used in single ply co

In the life of this product that you have been doing this process, has the material alway's been IT180 material? One problem with Lead free material is that it is more fragile that standard FR4 Epoxy laminate. And is known to have chipping or fractu

Embedded Passive Technology is a viable technology that has been reliably used in the defense and aerospace industry for over 20 years. Embedded Passive (Resistors and Capacitors) Technology have a great potential for high frequency and high density applications. It also provides better signal performance, reduced parasitic and cross talk. This paper summarizes the selection of resistor embedded materials, evaluations of resistive material (Phase 1) and duplication of a complex digital design (Phase 2). Phase 1 –resistive materials (Foil 25Ω/sq NiCr and 1kΩ/sq CrSiO) and resistive-Ply materials (25Ω/sq and 250Ω/sq NiP) were chosen for evaluation.
