The PTH acts like a rivet, which resists this expansion, but the Cu barrel is stressed and may crack, causing electrical failure Figure 574 also illustrates the increasing strain on the barrel associated with a high temperature excurFIGURE 573 Schematic diagram of a platedsion Failure may occur in a single cycle or may take place by through-hole in a cross section of a four-layer printed initiation and growth of a fatigue crack over the course of a circuit board showing common failure locations under number of cycles For high-aspect-ratio through-holes subject thermal stress to repeated thermal shocks from room temperature to solder reflow temperatures (220 to 250 C) during board fabrication (eg, hot-air solder leveling) and assembly (reflow, wave soldering, rework), it is not unheard of to encounter failures after 10 or fewer of these thermal cycles.

On a physical level, the number of thermal cycles to failure is affected by the strain imposed on the Cu in each cycle and the fatigue resistance of the copper These factors are in turn controlled by a number of environmental, material, and manufacturing parameters Lowcycle metal fatigue, in which most of the strain is plastic strain, can be treated approximately with the Coffin-Manson relation: Nf where Nf e ef m = = = = 1 2 ef e.

This is one port or eight lines of data. Half the port can also be used. See the data sheet. Backlight power. Backlight ground. These two lines can be ignored.

number of cycles to failure strain strain ductility factor, which correlates closely with tensile ductility constant near 2.

circuit board that this coupling agent improves the resin to glass adhesion both during the circuit manufacturing process (for example, in mechanical drilling) as well as within the actual end-use environment of the circuit. The coupling agent also plays a role in long-term CAF resistance, which is discussed in Chap. 9. A variety of these compounds are commercially available, with the specific choice primarily driven by the type of resin to be applied to the fiberglass cloth. Figure 7.18 provides examples of silane coupling agents.

Other Reinforcements While woven fiberglass cloth makes up the overwhelming majority of the reinforcements used for printed circuit base materials, other types can be used exclusively or in combination with woven glass fabric These other reinforcements include the following 7541 Glass Matte Compared to woven cloths, glass matte reinforcement exhibits a more random orientation Chopped strand matte consists of fiberglass strands that have been chopped into 1- to 2-inch lengths and distributed evenly Continuous strand matte, as the name implies, consists of continuous strands of fiberglass in a random, spiral orientation Glass matte is used in the core of CEM-3, which is used in relatively unsophisticated products 7542 Aramid Fiber As opposed to the inorganic chemistry of fiberglass reinforcements, aramid fibers consist of aromatic polyamide organic compounds, and therefore exhibit different properties.

The unique properties of aramid fibers can offer advantages in specific highperformance printed circuits and laminate-based multichip modules (MCM-L) For example, aramid fiber-reinforced materials are sometimes used in microvia applications since they are easily ablated by plasma or laser Other interesting properties of aramid fibers are their low weight, high strength, and negative coefficient of thermal expansion (CTE) in the axial direction When combined with the resin system, the resulting composite can offer reduced overall CTEs in the X-Y plane compared to conventional materials 7543 Linear Continuous Filament Fiberglass A unique process for producing fiberglass-reinforced laminates winds continuous yarns in a linear orientation The resulting laminate possesses three layers of fiberglass filaments, with the outside layers parallel to each other and the middle layer perpendicular to the outside.
