Check Cart/Check Out 
The increasing density and performance of today's electronic products are requiring new solutions. Amongst the solutions is to use resistors integrated into the printed circuit board. Using integrated resistors offers to the designer the choice of designing a resistor either on the surface or buried internally within the layers of a printed circuit board. The resultant resistor is very thin and flat, and what we call planar. This entire approach transforms a typical printed board from being strictly attachment and interconnect medium to containing integral resistors.
Using buried resistors is not something new or has been just developed. The technology was first developed in 1972, over a quarter century ago. The origin of these types of resistors can be traced back to the hybrid circuit industry. Since the time of the development of planar buried resistors they have been used to solve engineering problems on designs, particularly for high speed circuitry, such as ECL and GaAs, and now for high-density TTL/CMOS products sucha as the Pentium 4™ by Intel where there are a high concentration of resistors and precious little real estate. Who Will Benefit This book will be of immense value to both circuit designers as well as CAD designers, and those involved in product testing, fabrication, troubleshooting and debug of high-speed products.
