Description : Surface mount technology (SMT) is a mature technology. SMT allows placement of more surface mount components (SMC) into smaller and tighter printed circuit board (PCB) areas. This increased density means increased performance and power in smaller packaging systems, and allows manufacturing of smaller and higher performance products at lower cost. The advance of integrated circuit (IC) technology and the requirements of high density for high-speed circuity is driving the design of SM C to higher pin count and smaller package size. In general, the higher pin count and smaller package size are accomplished by reducing the bond pad size and spacing (pitch) on the chip level and the lead/pin/solder dimensions and pitch on the chip carrier (module) level. The last few years have witnessed an explosive growth in the research and development efforts devoted to FPT as a direct result of the rapid growth of SMT and miniaturization. Some examples are: hand held lightweight video recorders that can take sharp pictures, hand held lightweight devices that can track the worldwide package movements, and portable computers with tiny yet powerful microprocessors and large memory capability that can fit into a briefcase or into the palm of your hand.
Description : Fine pitch high lead count integrated circuit packages represent a dramatic change from the conventional methods of assembling electronic components to a printed interconnect circuit board. To some, these FPTpackages appear to bean extension of the assembly technology called surface mount or SMT. Many of us who have spent a significant amount of time developing the process and design techniques for these fine pitchpackages haveconcluded that these techniquesgobeyondthose commonly useed for SMT. In 1987 the presentauthor, convincedofthe uniqueness ofthe assembly and design demands ofthese packages, chaired ajoint committee where the members agreed to use fine pitch technology (FPT) as the defining term for these demands. The committee was unique in several ways, one being that it was the first time three U. S. standards organizations, the IPC (Lincolnwood, IL), theEIA(Washington, D. C. ),and theASTM (Philadelphia),cametogether tocreate standards before a technology was in high demand. The term fine pitch technology and its acronym FPT have since become widely accepted in the electronics industry. The knowledge of the terms and demands of FPT currently exceed the usage of FPT packaged components, but this is changing rapidly because of the size, performance, and cost savings of FPT. I have resisted several past invitations to write other technical texts. However, I feel there are important advantages and significant difficulties to be encountered with FPT.

Description : Solders have given the designer of modern consumer, commercial, and military electronic systems a remarkable flexibility to interconnect electronic components. The properties of solder have facilitated broad assembly choices that have fueled creative applications to advance technology. Solder is the electrical and me chanical "glue" of electronic assemblies. This pervasive dependency on solder has stimulated new interest in applica tions as well as a more concerted effort to better understand materials properties. We need not look far to see solder being used to interconnect ever finer geo metries. Assembly of micropassive discrete devices that are hardly visible to the unaided eye, of silicon chips directly to ceramic and plastic substrates, and of very fine peripheral leaded packages constitute a few of solder's uses. There has been a marked increase in university research related to solder. New electronic packaging centers stimulate applications, and materials engineering and science departments have demonstrated a new vigor to improve both the materials and our understanding of them. Industrial research and development continues to stimulate new application, and refreshing new packaging ideas are emerging. New handbooks have been published to help both the neophyte and seasoned packaging engineer.
