[0057] Another embodiment of the utility model provides an electronic assembly 1.

[0058] As can be understood from market data statistics, cockroaches are a common cause of damage to kitchen appliances. Cockroaches like warm and humid environments, and the interior of kitchen appliances provides just such conditions. The circuit board 11 in the appliance generates heat during operation, which will attract more cockroaches. Cockroaches crawling on the circuit board 11 will cause short circuits between devices, resulting in the entire device being unable to work, and the eggs laid by cockroaches on the circuit board 11 and the excrement left by cockroaches will also corrode the devices, affecting the service life of the entire device.

However, some appliances such as microwave ovens cannot be completely sealed due to assembly or heat dissipation during operation, and need to reserve air ducts. The cockroaches can enter the circuit board 11 inside the appliance through the air duct opening. If the air duct opening is too small, it will affect the heat dissipation of the device, and due to the super stretching ability of the cockroaches, reducing the air duct opening has little effect on preventing the cockroaches from entering the inside of the appliance.

[0060] The electronic assembly 1 of the embodiment is made of a material that can drive away cockroaches without harming the human body, such as peppermint oil, eucalyptus oil, garlicin, dichlorobenzene and dimethyl disulfide, as a pest control material to make a master batch, mixed with plastic particles such as polypropylene, polyethylene and polystyrene, mixed in a certain mass ratio (between 3%-25%), and the master batch and the polypropylene, polyethylene and polystyrene particles are made into a circuit board support (i.e. the support plate 12) or a control box wrapped around the circuit board 11 by injection molding. The circuit board support has the effect of driving away cockroaches, and can protect the circuit board 11 from damage caused by pollution of cockroach crawling and excrement.
