Dielectric Material Selection

Compex Corporation has characterized many different dielectric materials suitable for high performance chip capacitor applications. These dielectrics are listed as standard (Table 1 and Table 2). Dielectrics characterized but not listed are also available.

CLASS I - This class of dielectrics consists of material exhibiting very low losses, extremely low or closely controlled temperature coefficients, negligible voltage and frequency coefficients, no aging effects, and high insulation and dielectric breakdown.

CLASS II - This class of material is characterized by high dielectric constants, increased losses and higher temperature coefficients. The voltage and frequency coefficients as well as aging effects are no longer negligible. These properties are inherent with this class of material but the high dielectric constants permit the use of smaller size to achieve low series inductance and meet dimensional requirements. Capacitors made with these materials are often used for coupling of microstrip line circuits where the small chip size is necessary. Used as bypass capacitors, the small size provides low series inductance and dielectric losses are of little or no concern.

Commonly Used Mounting and Termination Methods

Mounting can be accomplished by:

1.      Soldering with the use of pre-tinning and solder reflow, solder preforms, solder paste etc.

2.      Eutectic bonding with appropriate metalizations of the surfaces to be joined and the use of compatible interface preforms.

3.      Conductive Epoxy

 

Termination can be made by:

1.      Soldering of wire of ribbon leads (minimum chip size limited by user's soldering techniques).

2.      Thermal compression, thermasonic, or ultrasonic bonding with aluminum or gold wire.

3.      Conductive Epoxy

Two Electrode - Series CSA

This classic design is the simplest and most widely used. The chip size, shape and electrical properties may be determined and specified from the dialectric material data and the capacitor selection chart.

Chip Sizes: Length or width .007" and up, square or rectangular.

Capicitance: 0.08 to 10,000 pF

Split Electrode - Series CSB

A single full electrode is provided on one side of the capacitor and split electrodes on the other side. This design opens up a number of application possibilities. This is a three terminal capacitor which can be used as two capacitors with a common electrode or as serially connected capacitors so that connections may be made on one side of the chip only. This design is often used in microstrip coupling to eliminate lead inductance and raise the self resonance frequency.

Multiple Values, Custom - Series CAX

A common electrode on one side of the chip and multiple electrodes on the other side. The capacitor array can be used as individual capacitors on a single chip or as a step adjustable capacitor by connecting combinations of electrodes to achieve the desired capacitance. Please call Compex Corp. for final details and specifications.

Step Adjustable Array - Series CAD

The arrays of capacitors are arranged in binary ratios (1-2-4, 1-2-4-8, and 1-2-4-8-16) to allow adjustment of capacitance from 1 to 31 units by connecting appropriate electrodes in parallel. Additional values of capacitance can be obtained by using series and/or parallel connections. Individual electrode values from 0.1 pF, chip size dependent on values and dielectric.

Row Caps - Series CRO

Row caps are used where arrays of capacitors (not necessarily identical) are needed, usually for decoupling/bypass of GaAs integrated circuits. Values up to 1000 pF per capacitor. Up to 8 capacitors per array are available. Typical overall dimensions range from 20x65 mils to 40x125 mils. Call Compex with your requirements.

Margin Caps - Series CSM

Margin caps have the topside electrode withdrawn from the edges in order to increase the distance between electrodes and dramatically decrease the possibilities of shorting when epoxy die mounting. This style is also widely used for optical recognition based assembly.
