Introduction Contemporary electronic board designs are becoming more challenging to designers than ever before. In today’s thick film, component applications designers are often faced with a trade-off between process flexibility and component performance. In terms of magnetic sensitive applications, this often requires the use of components that are sensitive to processing or attachment methods and therefore limit options for installation. At times this restricts the use of certain solders, temperatures or multiple re-flow operations. In applications where extreme processing is used with vulnerable components, failure modes can include component detachment or intermittent loss of continuity due to metal leaching of contacts and terminals. In order to understand this challenge and its factors, it is helpful to list the perfect performance characteristics of a thick film component. 1) Withstands high heat 2) Resists high Sn content solder 3) Non-magnetic 4) RoHS compliance 5) Affordability 6) Value diversity In designs where magnetism and RoHS compliance are in demand (i.e. medical imaging) resistance to high temperature solder and “non-magnetic” properties are critical. Unfortunately, they oppose each other from a process perspective. Traditionally, highheat RoHS compliant applications could often be addressed with nickel-barrier parts. These parts are readily available and very durable due to [...]
A ThermaBridge™ is a specialty thick film component developed and offered by IMS for use in the thermal management of electronic devices and modules. These products operate under the simple principle of conducting as much heat energy as possible, while simultaneously serving as an outstanding insulator of electrical energy and signal. The combination of these characteristics makes the ThermaBridge™ a very useful and flexible component that designers use to move heat either in, out, or to balance the temperature between two locations. ThermaBridges™ accomplish this without any fans, power, or moving parts making them useful for every electrical design sensitive to the effects of thermal energy. ThermaBridges™ operate by providing an electrically isolated, thermally active link between high heat generating areas and low temperature heat sinks or other locations within a circuit. According to Fourier, maximizing heat flow from one high temperature area to a lower one is made efficient by limiting the distance between the two points, maximizing the area of the conductive path and optimizing the material’s conductive heat properties. ThermaBridges™ do this by using Aluminum Nitride ceramic and offering a variety of thicknesses, lengths and widths to suit any thermal/mechanical requirement. For example if we take the [...]

Attenuators are passive two-port devices that reduce or attenuate the high level output of a signal generator. They are often used to provide a lower level signal to an antenna input of a sensitive radio receiver or similar device. Attenuator accuracy and overall effect on a system is also important to know particularly in applications for test equipment or other sensitive electronics. Improving Frequency Response The IMS A-0402WA attenuator has been characterized up to 40GHz. When this component is mounted upside down with the resistor and the transmission line in the same plane, improvements can be gained which reduces losses and minimizes capacitance effects. Face down mounting has several other advantages such as reduced current loop area, lower ESL, improved power handling and reduced overall insertion loss. Figures 1 and 2 demonstrate the improvement of physical mounting geometry with respect to insertion loss. As seen in the plots above, the two mounting techniques provide the same level of response up to about 8 GHz, at which point the ‘face down’ attenuator begins to outperform the face up attenuator. The improvement becomes more dramatic as the frequency increases. Improvement through controlled device impedance For greater improvement to the performance, the [...]

High ohmic valued chip resistors exhibit characteristics of both insulators and normal resistors. As a result, a chip resistor may have a significant voltage coefficient of resistance, i.e., the resistance may vary with the applied voltage. This mandates that a fixed voltage source rather than a fixed current source be utilized when measuring these devices. Resistances can then be computed as volts/amperes. The applied voltage for a high ohmic value chip resistor is often specified as appropriate for the application to assure correlation. Typical values of applied voltage are 1 and 5 volts DC. This requirement leads to the measurement of very low currents and the attendant problems of such measurements. The problems of low current measurements include: 1. Noise currents generated in the connecting cables when flexed (triboelectric effect) 2. Noise from sources other than the cables 3. Cable, fixture and probe leakage currents 4. Cable, fixture and other stray capacitances 5. Radio Frequency Interference (RFI) 6. Characteristically high Temperature Coefficients of Resistance (TCRs) These problems can be minimized by: 1. Properly connecting the resistor to the measurement system. 2. Properly guarding and shielding to reduce or eliminate electrostatic noise. IMS recommends that all meters be calibrated to [...]
