2UUL BH13 Mid-Layer Reball Base 5-in-1, iPhone 12-16 Pro Max

Every iPhone generation since the 12 has its own interposer layout, and lining up a stencil by eye wastes time. The 2UUL BH13 is a 5-in-1 reball base with alignment slots for iPhone 12 to 16 Pro Max mid-layer boards.

Its heat-resistant metal base spreads heat evenly, with anti-slip clamping so the board doesn't shift. It measures 13 x 8.4 x 1.1 cm and weighs 434 g. The listing describes a modular design but doesn't list the five modules.

When the BH13 helps

• A mid frame with missing balls after board separation.

• Cracked interposer joints that cause no power or no signal.

• A board that shifts while reballing under hot air.

• Liquid damage between layers that needs a full reball.

Working method

Clean the mid frame pads flat, seat it in the matching slot and clamp it. Apply paste through the stencil, reflow evenly and let it cool before lifting.

Choose the BH13 if you reball iPhone 12 to 16 boards often; the BH11 universal holder suits other models.
