摘要： The present invention is a method of providing a protective covering on an electronic package including a first circuitized substrate, a semiconductor chip positioned on and electrically coupled to the first substrate, and a plurality of conductors also on the substrate for electrically connecting the substrate to an external circuitized substrate. In one version, the method comprises covering substantially all of the external surfaces of the substrate, the semiconductor chip and a portion of the plurality of conductors with a protective covering from immersion in a dielectric solution (e.g., TEFLON AF). The coatings can also be applied by brushing, spraying, or chemical vapor deposition. In an alternative embodiment, all of the external surfaces, including all of the conductors, are coated with the protective covering (e.g., to facilitate package shipment or other handling). The resulting electronic packages are also described herein.

摘要： A method for coating cloth especially fiberglass sheets with a resin and resulting structure is provided. The coating is performed in two steps. In the first step, essentially all of the strands of the fiberglass are coated with the resin solvent mixture while maintaining the interstices or openings essentially free of the solvent mixture. This first coating is then partially cured to the extent that it will not redissolve in a second coating of the same resin solution. The coated fiberglass with partially cured resin thereon is then given a second coating of the same resin mixture which coats the first coating and fills in the interstices between the fibers. This second coating is then partially cured, which advances the cure of the first coating and results in an impregnated fiberglass cloth structure for use as sticker sheets. During lamination, the first coating acts like an impenetrable insulating sheet, preventing resin displacement and, therefore, preventing glass fiber contact with the conductive planes. The second coating is fluid enough to fill in spaces in the planes and to form the adhesive bond to cores and conductive layers.

摘要： A method for coating cloth especially fiberglass sheets with a thermosetting resin and resulting structure is provided. The coating is performed in two steps. In the first step, essentially all of the strands of the fiberglass are coated with the resin/solvent mixture while maintaining at least some of the interstices or openings essentially free of the solvent mixture. This first coating is then partially cured to between about 70% and 90% of full cure. The coated fiberglass with partially cured resin thereon is then given a second coating of either the same or different thermosetting resin mixture which coats the first coating and fills in the interstices between the fibers. This second coating is then partially cured, which advances the cure of the first coating past 80% full cure and results in an impregnated fiberglass cloth structure for use as sticker sheets. During lamination, the first coating acts like an impenetrable insulating sheet, preventing resin displacement and, therefore, preventing glass fiber contact with the conductive planes. The second coating is fluid enough to fill in spaces in the planes and to form the adhesive bond to cores and conductive layers. The structure reduces the tendency of the resin to flake and produce dust during subsequent processing operations.

摘要翻译： 提供了一种用热固性树脂涂布布尤其是玻璃纤维片并得到结构的方法。 涂层分两步进行。 在第一步骤中，玻璃纤维的基本上所有的股线都涂覆有树脂/溶剂混合物，同时保持至少一些间隙或开口基本上不含溶剂混合物。 然后将该第一涂层部分固化至完全固化的约70％至90％之间。 然后将其上具有部分固化的树脂的涂覆的玻璃纤维给予相同或不同的热固性树脂混合物的第二涂层，所述热固性树脂混合物涂覆第一涂层并填充纤维之间的间隙。 然后将该第二涂层部分固化，这使得第一涂层的固化达到80％全固化，并且导致浸渍的玻璃纤维布结构用作贴纸。 在层压期间，第一涂层的作用类似于不可渗透的绝缘片，防止树脂移位，因此防止玻璃纤维与导电平面接触。 第二涂层是足够流体以填充平面中的空间并形成与芯和导电层的粘合剂粘合剂。 该结构降低了在随后的加工操作期间树脂剥落并产生灰尘的倾向。

摘要： A method for coating cloth especially fiberglass sheets with a thermosetting resin and resulting structure is provided. The coating is performed in two steps. In the first step, essentially all of the strands of the fiberglass are coated with the resin/solvent mixture while maintaining at least some of the interstices or openings essentially free of the solvent mixture. This first coating is then partially cured to between about 70% and 90% of full cure. The coated fiberglass with partially cured resin thereon is then given a second coating of either the same or different thermosetting resin mixture which coats the first coating and fills in the interstices between the fibers. This second coating is then partially cured, which advances the cure of the first coating past 80% full cure and results in an impregnated fiberglass cloth structure for use as sticker sheets. During lamination, the first coating acts like an impenetrable insulating sheet, preventing resin displacement and, therefore, preventing glass fiber contact with the conductive planes. The second coating is fluid enough to fill in spaces in the planes and to form the adhesive bond to cores and conductive layers. The structure reduces the tendency of the resin to flake and produce dust during subsequent processing operations.

摘要： A method for coating cloth especially fiberglass sheets with a resin and resulting structure is provided. The coating is performed in two steps. In the first step, essentially all of the strands of the fiberglass are coated with the resin solvent mixture while maintaining the interstices or openings essentially free of the solvent mixture. This first coating is then partially cured to the extent that it will not redissolve in a second coating of the same resin solution. The coated fiberglass with partially cured resin thereon is then given a second coating of the same resin mixture which coats the first coating and fills in the interstices between the fibers. This second coating is then partially cured, which advances the cure of the first coating and results in an impregnated fiberglass cloth structure for use as sticker sheets. During lamination, the first coating acts like an impenetrable insulating sheet, preventing resin displacement and, therefore, preventing glass fiber contact with the conductive planes. The second coating is fluid enough to fill in spaces in the planes and to form the adhesive bond to cores and conductive layers.

摘要翻译： 提供了一种用于涂布特别是具有树脂和结构的玻璃纤维板的布的方法。 涂层分两步进行。 在第一步骤中，玻璃纤维的基本上所有的股线都涂覆有树脂溶剂混合物，同时保持间隙或开口基本上不含溶剂混合物。 然后将该第一涂层部分固化至其不会再溶解在相同树脂溶液的第二涂层中的程度。 然后对其上具有部分固化的树脂的涂覆的玻璃纤维进行涂覆第一涂层的相同树脂混合物的第二涂层，并填充纤维之间的间隙。 然后将该第二涂层部分固化，这促进了第一涂层的固化，并产生用作粘贴片的浸渍玻璃纤维布结构。 在层压期间，第一涂层的作用类似于不可渗透的绝缘片，防止树脂移位，因此防止玻璃纤维与导电平面接触。 第二涂层是足够流体以填充平面中的空间并形成与芯和导电层的粘合剂粘合剂。
