System z

IBM's family of 64-bit mainframes, introduced in 2000 as the zSeries. It includes the z9, z10 and zEnterprise z196, z114, zEC12 and zBC12 models, all of which are robust, mission critical computer systems that generally run under IBM's z/OS or z/VM operating systems.

IBM's z/Architecture was a major upgrade to the previous ESA/390 mainframes. The first z mainframe was the high-end 900 line, followed in 2002 by the zSeries 800, geared to the mid-size customer. Following is a list of "z" models over the years. The enterprise class designation refers to the high-end machines. See z/OS, zEnterprise, z/Architecture, IBM branding and System/390.

The new 14-layer PCBs were manufactured using BC24, BC12, and BC12TM materials as the thin laminate cores, respectively.
BC24 and BC12 are modified epoxy substrates that are 24 and 12 micrometers in thickness respectively.
To evaluate the performance of the FaradFlex materials, the BC24, BC12, and BC12TM boards were populated only with bulk &coupling capacitors, and the FR-4 board was fully populated with bulk and high-frequency SMT decoupling capacitors.
BC12 is slightly trailing behind, followed by BC24.
FIGURE 7 shows the measurements for the BC12 boards.
As shown in Table 1, by comparing embedded capacitor material with same Dk value and different thickness, BC24, BC16, BC12 and BC8, influence of dielectric thickness can be observed.
The first set (FIGURE 6a) is a comparison between BC12 and BC12TM, in which both materials have the same thickness of 12[micro]n but have different Dk of 4.
