are accessible to maintenance personnel internal to the system need not be tested, as maintenance personnel should have already discharged themselves when approaching this section of the EUT. The ESD simulator should be gradually increased from a minimal to a maximum voltage level to ascertain the threshold of failure. Fifty single discharges shall be applied in the most sensitive polarity on the unit, allowing at least 1 second between discharges. The discharge points may be selected during the exploration phase using a repetition rate of 20 discharges per second. For contact discharges, the tip on the test simulator needs to have a sharp point (Figure 7.11). A pointed tip is required to pierce through paint and plating, thus ensuring optimal contact with the EUT. The tip should be in contact prior to the discharge switch being closed. When painted metal surfaces exist, the sharp tip must puncture the surface. Where such a source is intended to be insulating, such as a plastic bezel, a direct-contact discharge cannot occur. For this type of test, the air discharge method is required. The air discharge tip has a rounded end which simulates a typical human finger that could touch the EUT or other metallic reflecting surface (Figure 7.11). For the air test, the discharge switch is closed and the round tip of the simulator approaches the EUT as fast as possible, consistent with not actually causing mechanical damage when the tip touches the coupling plane or EUT. This test most closely approximates the real-world environment because in a typical situation ESD results from a charged human body or furniture that usually approaches the receptor equipment gradually, discharging static electricity during the process of approach. Atmospheric conditions such as humidity and air pressure may influence test results. In addition, the speed of approach can also alter test results substantially.

with it, so I am assuming that every organization reading this will have those tools in place. If this is not the case, I strongly recommend reading Tom Ahern s excellent new book on cases, Seeing Through a Donor s Eyes, to be Published by Emerson & Church in early 2009, a fantastic reference point on the subject.

points of equal resistance and all points of equal reactance were connected, and the result is the Smith Chart shown in Figure 3.7b. The distance out from the center of the Smith Chart is the amplitude of the re ection coef cient (i.e., the amplitude of the re ected electric eld relative to the incident electric eld), and the angular location around the chart is the phase of the re ected electric eld relative to the incident electric eld. However, instead of amplitude and phase coordinates, the Smith Chart uses coordinates of resistance and reactance. Then, if the re ection coef cient of a mismatch is known, it can be plotted on the Smith Chart to determine the resistive and reactive parts of its impedance. All lines of equal resistance and equal reactance are normalized, and the meaning of this normalization is shown in Figure 3.12. The actual resistances and reactances are not plotted, but they are divided by the characteristic impedance of the transmission line. For example, if R 75 V and X 25 V in a transmission line where Z0 50 V, the normalized impedance (z) is z 75V 25V j 50V 50V

Assembly FeatureManagers are hard enough to manage when they become full of parts; they become even more unmanageable when they also need to include the many types of fastener parts. As a result, I recommend that fasteners, as well as any other type of part that is found in large quantity in the assembly, be organized into folders, as shown in Figure 17.30. You should also group parts of the same size or function together.

The formula (14.9) provides a saddlepoint approximation to the joint density of an M-estimator. However, often we are interested in marginal densities and tail
