Bench tools compared by the numbers manufacturers actually publish.
Twelve hot air rework stations, straight from the manufacturers' own spec sheets: six different airflow conventions, one number that is not litres per minute, and the 2x correction nobody applies.
Bandwidth, sample rate and the probe that quietly ruins your measurement - how to choose and use a first oscilloscope for board-level repair.
Input impedance, burden voltage, counts and CAT ratings, decoded from two real published spec sheets — the multimeter numbers that decide whether a reading is true at a repair bench.
