UMLCAR, April 29, 2007 Radio Sounding and Plasma Physics Symposium URSI/COSPAR Inter-Union Working Group on the INTERNATIONAL REFERENCE IONOSPHERE (IRI) Terms of Reference The IRI Task Group was established to develop and improve a reference model for the plasma parameters in the Earth ionosphere.
Part 2: Top-Side Service Procedure Page 55 July 2010 Technician Study Guide Part 2: Top-Side Service Procedures The top-side service procedure consists of the following tasks:
Each of these sections include both a topside and a bottomside component. The topside signal generation is illustrated in Figure 2. FIGURE 2 . Topside Signal Generation A 10 MHz master clock signal is generated in the bottomside receive electronics and transmitted to the topside signal generation ...
Finally, in these bottomside measurements the sensor was fixed to always be parallel to the original plane of the sample (rather than the dent profile) as it traveled over the dent. 2.1 Small dents: bottomside MFL contour plots, before and after annealing: Figure 3 shows MFL signal contour plots ...
The board is shown in Figures 1 (topside) and 2 (bottomside). Most of the components reworked were on the topside. The bottomside has one PBGA544 component and some TSOP and 2512 chip components.

Much has been written about recommended SMD pad designs and layouts for bottomside applications. However, these guidelines are rarely used. Most often, topside pad designs are used with bottomside PCB fabrication.
