Soldering station, ultrasonic cleaner and preheat plate.
As in any service center without a soldering station, nowhere! And since data recovery implies a temporary resurrection of the drive - you can’t do without these devices! For chip off and desoldering bga, lga, tsop, emmc (android devices), cob (monolith), nand memory chips, replacing burnt elements (diodes, drivers, processors, etc.) on the hard disk controller or ssd drive, flushing flooded circuit boards for other everyday data recovery tasks - without a hot air soldering station, ultrasonic cleaner, multimeter, preheat plate and laboratory power supply, adapters and pads, you just can not do!
