Therefore, the electronic A. 42 J. Quant package designer, taking this factor into account, shoUld assign work only to experienced potting organizations. 2. Because of the thermal insulating nature of the microballoon filler, the cure exotherm frequently reaches a peak of 190°F. Furthermore, processing characteristics presently preclude the possibility of a reasonably short-time, low-temperature cure for thermally sensitive components, as is possible with general-purpose systems. APPLICATIONS With careful design consideration, this resin system can be incorporated into electronic packages of the type that are currently being encapsulated with the more familiar filled resins.

The standard board is available in 18 in. by 18 in. nominal sheets and is supplied with Nema G 11 skins unclad or clad with 2 oz copper. id Nema G10 paper base epoxy, glassreinforced Melamine, and paper-base Melamine can also be supplied. The physical characteristics of the damped composite boards are compatible with the requirements of MIL- P-13949B. A typical comparison of test results for these boards is shown in Table II. lt is quite reasonable to conclude that no degradation of the capabilities of the board has resulted.

The preheated components and mold shall be partially filled with the warm, deaerated encapsulating compound. Degas the mold and components by placing them in a vacuum chamber and evacuating at a pressure of 1-3 mm Hg absolute and maintaining this reduced pressure for at least 3 min. Allow pressure to return to atmospheric. 1). 1 In some units the configuration and spacing of components may be such that in order to remove all entrapped air it will be necessary to introduce the encapsulating compound in two steps, evacuating as above after each step.
