LUOWEI LW-313 Mini Chip and Board Fixture

Reballing a loose chip is fiddly when the chip keeps sliding. The LUOWEI LW-313 is a small metal fixture that clamps single chips and small boards firmly.

It measures 70 x 60 x 21.5 mm and weighs 210 g net, with a packed size of 96 x 64 x 28 mm. The listing describes adjustable clamps and a precise grip for delicate parts.

When the LW-313 helps

• A chip that drifts under the stencil while you spread paste.

• A small sub-board with a damaged connector.

• A camera or charging flex with a cracked joint.

• Missing solder balls you are replacing one by one.

Using a small fixture

Clamp the chip by its edges and check it sits level before reballing. Metal fixtures draw heat away, so preheat a little longer than you would with the chip on a mat. Clean flux off between jobs.

For full logic boards, a larger holder like the D3 FA suits better; the LW-313 is for the small parts that larger fixtures can't grip. At 70 mm wide it fits under most microscope stages easily.
