Abstract
A carrier and package for plural semiconductor devices includes a member with device-conformal apertures therethrough. A first removable cover is attached to one side of the member to close one end of each aperture. After devices are inserted into the apertures with their first ends “up” and their second ends “down,” a second removable cover is attached to the other side of the member to close the other end of each aperture. After inverting the assembly, removal of the first cover presents the devices in the apertures with their second ends “up” and their first ends “down.”
Claims11
A method of inverting at a work location an article having first and second opposed surfaces both of which are generally normal to the article's periphery, which comprises:
- closing one end of an article-periphery-conformal aperture formed through a member to render the aperture a blind aperture;
- inserting the article into the blind aperture so that the first article surface is supported at the blind end of the aperture and its second surface is exposed at the work station;
- closing the other end of the aperture to render the aperture a closed aperture;
- and
- thereafter, inverting the carrier so that should the one aperture end be opened, the first article surface is exposed at the work station.
A method as in claim 4, wherein:
- the article is a BGA semiconductor device the first surface of which carries an array of one or more conductive balls,
- the member is a waffle pack, and
- the BGA device is initially inserted into the blind aperture with its second surface exposed following, and as a result of, a previous die bonding operation.
A method of packaging a BGA semiconductor device having first and second opposed surfaces both of which are generally normal to the device's periphery, a first surface of the device carrying an array of contact balls, which comprises:
- closing one end of a device-periphery-conformal aperture formed through a member to render the aperture a blind aperture;
- inserting the device into the blind aperture so that the balls on the first article surface are supported at the blind end of the aperture and its second surface is unsupported and exposed;
- and
- closing the other end of the aperture to render the aperture a closed aperture;
- the member being manipulable so that thereafter opening the one end of the closed aperture with the second surface of the device supported exposes the first device surface with the balls thereon.
A carrier for an article having first and second opposed surfaces both of which are generally normal to the article's periphery, which comprises:
- a member having an article-periphery-conformal aperture therethrough, the aperture being adapted to receive the article when the member is in a first orientation;
- a first cover removably associable with one side of the member to render the aperture a blind aperture into which blind aperture an article is insertable with the first surface abutting the first cover and the second surface exposed;
- a second cover removably associable with the other side of the member to render the blind aperture a closed aperture in which closed aperture an inserted article may be held, the member being manipulable into a second orientation wherein the second surface abuts the second cover so that the article is presented with the first side exposed following removal of the second cover.
