The Magnetic Field

Abstract We developed a system and a method to characterize the magnetic field induced by circuit board and electronic component, especially integrated inductor, with magnetic sensors. The different magnetic sensors are presented and several applications using this method are discussed. Particularly, in several semiconductor applications (e.g. Mobile phone), active dies are integrated with passive components. To minimize magnetic disturbance, arbitrary margin distances are used. We present a system to characterize precisely the magnetic emission to insure that the margin is sufficient and to reduce the size of the printed circuit board.

The increased usage of unmanned aerial vehicles has driven the desire for smaller and lighter missile bodies. The wiring harnesses required to connect the missile subsystems constitute a significant portion of the missile weight and cost. We have been exploring the development of flexible electronics substrates manufactured using ink jet technology on polyimide films. This technology has an advantage over traditional flex circuit manufacturing because in addition to creating traditional wiring patterns the ink jet technology enables the creation of passive components such as resistors and capacitors. The Dimatix DMP-2831 ink jet system uses individually controllable piezoelectric driven MEMS nozzles to precisely deposit nanoparticle inks. These inks are then annealed to form wiring patterns. We will present the process for converting traditional printed circuit board data formats to inkjet printable data, the process for depositing the ink, annealing and testing.

Printed Circuit

A novel process has been developed to embed discrete (surface mountable) passive components like capacitors, resistors and inductors using printed circuit board fabrication technology. The process comprises of mounting passive components on top surface of a core PCB (printed circuit board) material using surface mount technology. The passive components mounting were designed in multiple clusters within the PCB. Dielectric sheets are sandwiched between top surface of core PCB and second PCB material for lamination process. A direct interconnection of the passive components to one or more integrated circuits (IC) is further accomplished by mounting the ICs on the bottom surface of the core material in an area directly under the passive components. The close proximity of the embedded passive components such as capacitors to an IC improved electrical performance by providing impedance reduction and resonance suppression at high frequency range. The reliability of solder joints was evaluatedd by temperature cycling test.

The Impact

With the miniaturization of electronic products, reducing the size of the printed circuit board that forms the backbone of the product is paramount. Embedding passive components, which otherwise occupy valuable “real estate” atop the printed circuit board, into the printed circuit board substrate itself is one way of achieving this objective. This first part of this paper examines the techniques and advantages of embedding passives. Embedding passives also affects manufacturing system performance, due to a change in the processing sequence and changes to the processing times at resources. The latter portion of this paper describes a design for production tool for understanding the impact of embedding passives on the performance of a manufacturing system.

Electrical Impulses

The effects arising in an integrated microchip (IC) of a microcontroller (MC) performing test logic operations under the action of powerful electrical impulses are investigated. The IC MC STM8S003 was chosen as a typical microcontroller. The exposure was carried out by electric pulses with an electric field strength of up to 20 kV/cm and a duration of 6 ns. It is shown that impulse influences can lead to logical failures when performing IC MC logical operations, the effectiveness of the influence depends not only on the parameters of the electromagnetic pulse, but also on the specific operation performed during which it occurred. The repetition rate of electromagnetic pulses up to 1 kHz does not significantly affect the type of failures of the IC MC. The supply voltage of the IC MC affects its stability; to create a failure, an increase in the amplitude of the electromagnetic pulse is required with an increase in the supply voltage. Passive components of a printed circuit board are more susceptible to electromagnetic influences than IC MC.

Because of the high volume of processing, transmission, and information storage, electronic systems presently requires faster clock speeds tosynchronizethe integrated circuits. Presently the “speeds” on the connections of a printed circuit board (PCB) are in the order of the GHz. At these frequencies the behavior of the interconnects are more like that of a transmission line, and hence distortion, delay, and phase shift- effects caused by phenomena like cross talk, ringing and over shot are present and may be undesirable for the performance of a circuit or system.Some of these phrases were extracted from the chapter eight of book “2-D Electromagnetic Simulation of Passive Microstrip Circuits” from the corresponding author of this paper.
