Final answer:
It is false that stacking circuit boards is safe during disassembly when following ESD protection rules; physical damage can occur regardless of ESD precautions.
Step-by-step explanation:
When disassembling a computer, it is false that it's okay to stack circuit boards on top of each other as long as you follow ESD protection rules. Circuit boards should not be stacked on top of each other because they can still physically damage each other. Scratches or stress on components can ruin their functionality, even when proper ESD precautions are taken. Moreover, the sensitive contacts and components may bend or break under the weight, causing unnecessary risk to the hardware. Instead, each circuit board should be placed separately and ideally in anti-static bags or on anti-static mats to ensure both electrical and physical protection.
