1. Hash board repair and maintenance: The KF1990E is a direct replacement chip for faulty ASICs on the M73S hash board. When the miner experiences a drop in hash rate or chip damage, replacing this chip can restore the overall board performance.
2. Mining farm operation: For mining farms deploying M73S on a large scale, stocking KF1990E spare parts can minimize downtime and ensure return on investment.
3. Professional repair services: ASIC repair technicians and service centers need to use original KF1990E chips to repair components and hash boards to meet the growing demand for M73S miner maintenance.
1. Static electricity prevention is mandatory: The KF1990E is an electrostatic-sensitive device. Please use an anti-static workbench and anti-static tweezers during operation, and ensure proper grounding.
2. Professional installation is recommended: BGA/QFN/LGA package soldering requires specialized equipment and experience.
3. Post-installation testing: After replacement, please perform a comprehensive functional test to confirm that chip recognition and hash rate output are normal.
