pads of an IC at one end, spreads out to a much larger pitch, and attaches to pads on a PCB. The tape in the title describes the method for carrying the parts prior to assembly, which is a tape with the TAB lead frame and IC built into it. The tape is wound onto a reel for handling. The principle application of TAB components is products such as pagers and portable phones that are made in very high volume and can justify the automation involved in attaching TAB parts to substrates.

Flip Chip Flip-chip technology involves plating raised pillars of metal on the bonding pads of ICs, turning them upside down, and attaching them to a matching pattern on a substrate. The substrates are most often silicon and precision ceramics. From this description, it can be seen that this is a very specialized packaging method. To succeed, a source of tested good bare die with plated-on pillars must be available. This situation occurs almost exclusively in very high performance supercomputers where the ICs have been specially designed for the application or in very high volume applications such as pagers and cellular phones.

BGA BGA or ball grid array is a relatively new technology that is a cross between pin grid arrays and surface-mount. High-pin-count IC die are mounted on a multilayer substrate made from ceramic or organic material. The die are connected to the substrate using standard wire-bond techniques and encapsulated in epoxy or another form of cover. The bottom side of the substrate contains an array of high-melting-point solder balls which connect to the wire-bond pads through the multilayer substrate. These balls mate with a matching array of pads on the PCB and are reflow soldered during the same operation as all other surface-mount parts. (See Fig. 13.11.) The appeal of BGA technology is as an alternative to high-pin-count, fine-pitch SMT ICs. As mentioned earlier, assembling high-pin-count, fine-pitch SMT parts is very difficult, owing to the fragile nature of the component leads. BGAs represent a much more robust package during component-level test and during assembly. As with most technologies, there are some disadvantages to BGAs. Among these are:

The solder joints are hidden from view, so inspecting them requires x-rays. The solder joints are not accessible for rework, so the soldering process must have a very high success rate. Part removal requires special tooling. The pattern on the PCB surface is an array of pads that require one via each all the way through the PCB, hampering routing. All component leads are concentrated in a much smaller area than the equivalent part in a fine-pitch SMT package. This concentrates the wiring in a small area pierced with many vias. As a result, the BGA PCB will likely have more wiring layers than the equivalent SMT PCB. The BGA package is more expensive than the equivalent fine-pitch SMT package, by as much as three times.

Wire-Bonded Bare Die As the name implies, this method of assembly involves attaching bare IC die directly to a substrate using an adhesive or reflowing solder and connecting the bonding pads to pads on the

PCB using wire-bond techniques. Virtually all digital watches and many other similar consumer products use this assembly technique. It is very inexpensive when used in very high volume products with only a single IC to connect.

A wide variety of materials has been developed for use in packaging electronic circuits. These can be divided into three broad classes: reinforced organics, unreinforced organics, and inorganics. These are used primarily for rigid PCBs, flexible and microwave/RF PCBs, and multichip modules, respectively. The following treatment of the available materials concentrates on the principle materials systems used in PCB design along with the properties that warrant their use. See Chaps. 6 and 8 in this handbook for detailed data provided on loss tangents, temperature of coefficient of expansion, glass transition temperature, and other electrical properties. IPC, the Institute for Interconnecting and Packaging Electronic Circuits, publishes a comprehensive series of standards that list in detail the properties of all types of laminates, resins, foils, reinforcement cloths, and processes that are candidates for the manufacture of PCBs. These standards start with IPC-L-108B and run up to IPC-CF-152. It is recommended that copies of the applicable standards be obtained at the start of a program in order to ensure a thorough understanding of all important characteristics of the materials being considered for a design. Properties important to the manufacture of PCBs include (see Table 13.3):

Glass transition temperature Tg The temperature at which the coefficient of thermal expansion in a resin system makes a sharp change in rate from a slow rate of change to a
