Abstract
A method of encapsulating an article having first and second surfaces, includes positioning the article on a carrier such that at least a portion of the first surface contacts the carrier. A portion of the carrier carrying the article is then positioned within a mold and a seal is formed between the mold and the carrier. The mold is then filled with an encapsulating material to form a seal between the article and the carrier.
Claims18
A method of encapsulating an article having opposing first and second sides, comprising:
- positioning the article on a temporary carrier such that at least a portion of the first side contacts the temporary carrier in a manner to prohibit the flow of any encapsulating material between the temporary carrier and the first side of the article;
- positioning a portion of the temporary carrier carrying the article within a mold;
- forming a seal between the mold and the temporary carrier;
- filling the mold with an encapsulating material in a manner so as to cover at least the second side;
- removing the portion of the temporary carrier carrying the article from the mold;
- separating the article from the temporary carrier;
- and
- underfilling the first side of the article with an underfill material.
A method of encapsulating an article having opposing first and second sides, comprising:
- positioning the article on a temporary carrier such that the first side is supported by the temporary carrier to allow the flow of encapsulating material between a portion of the temporary carrier and a portion of the first side of the article;
- positioning a portion of the temporary carrier carrying the article within a mold;
- forming a seal between the mold and the temporary carrier;
- filling the mold with an encapsulating material in a manner so as to cover the second side and a portion of the first side;
- removing the portion of the temporary carrier carrying the article from the mold;
- and
- separating the article from the temporary carrier.

- positioning the article on a temporary carrier such that at least a portion of the first side contacts the temporary carrier in a manner to prohibit the flow of any encapsulating material between the temporary carrier and the first side of the article;
- positioning a portion of the temporary carrier carrying the article within a mold;
- forming a seal between the mold and the temporary carrier using clamping pressure;
- dynamically forming a seal between the article and the temporary carrier by injecting an encapsulating material into the mold onto the second side of the article;
- removing the portion of the temporary carrier carrying the article from the mold;
- separating the article from the temporary carrier;
- and
- underfilling the first side of the article with an underfill material.
