Antminer BM1370 Series ASIC Chip Tester for BM1370BB/BC/AA/PA/PB

BM1370 Series ASIC Chip Tester – Diagnostic Tool for Antminer S21 Pro / S21+ / S21XP

This BM1370 ASIC chip tester validates chip health across all BM1370 variants — BM1370BB, BC, AA, PA and PB — used on the Antminer S21 Pro, S21+, S21XP, S21XP Hydro and Bitaxe Gamma 601. It enables rapid fault identification before chip installation and repair verification after hashboard rework, preventing the costly mistake of soldering a defective chip onto a good board. Essential bench equipment for any shop handling S21-generation hashboard repairs.

Why Test Chips Before Installation

New and pulled ASIC chips can be defective — manufacturing rejects, ESD-damaged stock, or chips degraded during desoldering from donor boards. Installing an untested chip, reflowing it onto the hashboard, then discovering it's dead wastes time and risks pad damage from the unnecessary reflow cycle. Testing each chip before installation eliminates this waste and ensures every rework produces a working result on the first attempt.

How to Use

Place the BM1370 chip into the tester socket with correct orientation. Run the test — the tester validates the chip's hashing core, communication interface and power integrity. A pass/fail result tells you immediately whether the chip is suitable for installation. Test pulled chips after desoldering to confirm they survived the removal process, and test new stock to catch any defective units before they reach the board.
