Abstract
A substrate carrier which is used through beginning assembly operations such as solder reflow for attaching ball grid array devices to flexible substrates. The carrier includes a main structural support for centerly placing the substrate. The support member include two pairs of pins protruding from the support member to engage with a matching pair of datum apertures disposed inboard of the side edges of the substrate. A plurality of high temperature magnetic inserts are affixed into holes of the support member disposed parallel and outboard of the pins. The cover has two rows of apertures for engagement with the pins of the support member is attracted by the magnetic inserts forcing the outer periphery of the cover against the top surface of the substrate.

A substrate support carrier which is used through beginning assembly operations while holding flexible substrates, comprising:
- a main structural support member having a first surface for centerly supporting a substrate thereon, said support member including two pairs of pins protruding from said first surface, a first pair disposed towards one end of said support member and a second pair disposed towards the other end, said pins are spaced laterally in pairs to engage with a matching pair of datum apertures disposed inboard of side edges of said substrate;
- a plurality of high temperature magnetic inserts affixed into holes of said first surface of said support member, said magnets disposed parallel and outboard of said of pins;
- a cover for placing over and semikinematically pressing against top surface of said substrate, said cover having two rows of apertures for engagement with said pins of said support member.
A method of producing a substrate support carrier which is used through beginning assembly operations while holding a flexible substrate, comprising the steps of:
- providing a flexible substrate;
- providing a main structural support member having a first surface for centerly placing a substrate thereon, said support member including two pairs of pins protruding from said first surface, a first pair disposed towards one end of said support member and a second pair disposed towards the other end, said pins are spaced laterally in pairs to engage with a matching pair of datum apertures disposed inboard of side edges of said substrate, said support member having a plurality of high temperature magnetic inserts affixed into holes of said first surface of said support member, said magnets disposed parallel and outboard of said of pins, and
- providing a cover for placing over and semikinematically pressing against top surface of said substrate, said cover having two rows of apertures for engagement with said pins of said support member.
