2UUL BH16 NAND Reball Base, Magnetic Dual-Sided

When a phone's storage chip fails or has to move to a new board, it must be reballed first. The 2UUL BH16 is a magnetic, dual-sided reballing base dedicated to these NAND storage chips.

Magnets hold the chip and stencil in line, and the two sides cover different reballing needs. The listing describes heat-resistant material and a compact size but gives no dimensions or stencil list.

When NAND reballing comes up

• A phone stuck in a boot loop after a drop that cracked NAND joints.

• Data recovery from a dead board by moving the NAND.

• Storage errors from a faulty chip being replaced.

• A chip with missing balls after removal.

Step by step

Put the base on a steady surface and seat the NAND chip in its area. Attach the stencil with the magnets, apply paste and reflow following your usual reballing routine. Remove the chip and stencil once cool, then clean and store the base.

The BH16 is for NAND; the BH17 is the CPU version with a large stencil set. Check the photos to confirm the stencils you need are included, as the listing doesn't say.
