Experimental Verification of Damage of Scale Copper Powder to Equipment Electronic Components
The scale copper powder is one of the main components of the jamming agent in the jamming projectile.With good electrical conductivity and small size,the smoke screen particles formed after the ex-plosion of the jamming projectile are easy to enter the interior of the equipment through gaps.During the equipment movement,the smoke screen particles are further embedded into the pin gaps of the electronic components by vibration.This will cause short circuit failure of electronic components and do damage to the equipment.To solve this problem,a damage experiment is designed,and an oscilloscope is used to de-tect the electrical signal of the BIOS chip when the computer motherboard is started,in order to verify the damage of the scale copper powder to the computer motherboard.The results show that the computer motherboard is damaged by spreading 6.0 g of scale copper powder and vibrating for 60 s.The influences of the vibration factors on the damage is compared and analyzed,and the damage of electronic components caused by scale copper powder is analyzed.The damage of equipment electronic components caused by the explosion of jamming shells is evaluated,and it is verified that the scale copper powder will cause serious harm to equipment electronic components.The development direction of smoke-screen jamming agent is clarified.
