Medium used to apply epoxy to pieces or units. Squeeze bottles, syringes, needles, and meter mix equipment are all examples.

Organic and inorganic phosphates and polymers used in aqueous cleaning to assist in the removal of insoluble particles.

The measure of electrical energy absorbed and lost in the insulating material when energy is applied in a circuit. 20-3060 has a dissipation factor of .01. This means that .01% of the energy being stored (capacitance) is lost. Dissipation factor is the ratio of the resistive component of a capacitor to the capacitive reactance of the capacitor. Also referred to as Loss Tangent. ASTM D150-59T.

Solid photoresist applied to a surface by lamination of prefabricated film.

A package with two rows of leads extending at right angles from the base with standard spacing between the leads and row. This package is intended for through hole mounting.

An LED that emits light from its edge, producing more direction output than surface-emitting LED’s that emit from their top surface.

That property of materials by virtue of which they tend to recover their original size and shape after deformation. Note-if the strain is proportional to the applied stress, the material is said to exhibit Hookean or ideal elasticity.

Undesired coupling from one circuit, part of a circuit, or channel to another. 2. Any phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates and undesired effect in another circuit or channel.

Cathode ray tube.

The difference in the coefficients of thermal expansions of two materials or components joined together, which produces strains and stresses at joining interfaces or in attachment surfaces.

To change the physical properties of an epoxy by chemical reaction through polymerization, usually accomplished in the presence of heat and catalyst, alone or in combination.

The schedule of time periods at specified temperatures to which a reacting thermosetting plastic or rubber composition is subjected in order to reach certain specified properties.

The process of irreversibly polymerizing a thermosetting plastic by subjecting it to a temperature-time profile.

A catalytic or reactive agent which when added to resin causes polymerization.

The time-temperature profile needed to cure a thermosetting material like a bonding adhesive.

The time needed to properly cure a thermosetting plastic material.

Decibels relative to milliwatt.

Decibels relative to microwatt.

Direct current.

A unit of measurement indicating relative optic power on a logarithmic scale. Often expressed in reference to a fixed value, such as dBm (1 milliwatt) or dBA (1 microwatt).
