When the anode is very small compared to the cathode, its corrosion can be very rapid Conversely, if the anode is much larger than the cathode, corrosion is unlikely to be serious, particularly if the difference in electronegativity is small Conductive Anodic Filament Growth Conductive anodic filament growth (CAF) causes electrical shorts when a metal that dissolves anodically is redeposited at the interface between the glass (or other) fibers and the resin matrix of a printed circuit board Conductive anodic filament growth is promoted by delamination at the glass-polymer interface, which may in turn be promoted by various environmental stresses including high temperatures (greater than about 260 C for FR-4) and thermal cycling Shorts seem to occur most rapidly when a single fiber bundle connects two pads Once delamination has occurred, the metal migration that causes shorts to occur is promoted by increasing temperature, relative humidity, and applied voltage.

Small conductor spacings also significantly decrease times to failure12 In multilayer boards, failures occur faster on outerlayers than innerlayers because the surface layer absorbs moisture more readily By the same reasoning, solder mask and conformal coating both increase the time-to-failure because they slow the absorption of moisture from the atmosphere into the board Whiskers Whiskers are faceted filament-like structures that grow spontaneously on the surface of a plated metal and can cause shorts between closely spaced conductors (see Fig 5711) Whiskering can be differentiated from other causes of shorts such as dendritic growth, because neither an electrical field nor moisture is required for whiskers to form Whiskering is a particular problem with pure tin The whiskers grow in response to internal stresses in the plating or external loads Sn whiskers are commonly 50 mm long and 1 to 2 mm in diameter..

Once started, they may grow as fast as 1 mm per month. The tendency toward whisker growth is influenced by a variety of factors including plating conditions and the characteristics of the substrate. Growth may be inhibited by a Cu or Ni barrier layer beneath the tin coating. Pb seems to suppress whisker growth; eutectic Sn-Pb solder is considered almost immune. Whiskers do not cause the corrosion resistance or solderability of the tin coating to deteriorate, so tin may be used as a temporary finish. To avoid whiskering, plated pure Sn should not be used on closely spaced conductors that could short during service, such as connector terminations or component leads.13,14 57.2.2 Interconnect Failure Mechanisms 57.2.2.1 Thermally Driven Failure Mechanisms.

Thermal Fatigue of Solder Joints. Thermal fatigue of solder joints has been extensively researched in the last decade. The mechanism of fatigue, accelerated testing methods, and methods for predicting life have all been described at length, although there is still much controversy about many of the details.15 17 These references also illustrate how modern finite element methods can be used to model the strains in the solder under both operating and accelerated test conditions. This section briefly reviews some of the important principles underlying solder joint thermal fatigue. The focus of the discussion is on surface-mount solder joints, which have been extensively researched; however, many of the same principles also apply to through-hole solder joints. Through-hole joints are generally less prone to solder joint fatigue failures, so long as the through-hole barrel is full of solder. Ideally, complete fillets should be observed on both surfaces of the board. Reviews of this topic can be found in Refs. 18 and 19. Thermal fatigue in solder joints occurs because of the thermal expansion (CTE) mismatch between the PCB and the component interconnected by the solder joint (see Fig. 57.12).

The imposed thermal cycle T results in an imposed cyclic strain e of the solder joint, which is generally the weakest part of the system. The relationship is simple under the assumptions that the part and substrate are rigid, the solder joints are relatively small, and that homogeneous shear deformation caused by the global CTE mismatch predominates: e = ( T)( a)l h (57.1)
