Embodiment Construction

[0022] An ultra-clean tray for storing spare parts used in a clean room environment. Its cleaning process is as follows:

[0023] a. Manually pre-treat the tray to remove labels and other visible foreign matter on the surface.

[0024] b. Before entering the 1000-class clean room, first pass through the cargo shower. The function of the cargo shower is: the efficiency of the tray is 99.99%, the filter particles are > 0.3um, and the large particles on the surface are removed, thereby reducing the pollution to the 1000 class.

[0025] c. Employees in dust-free suits transport the pallets to the 1000-level environment. Class 1000 means that the number of particles with a size above 0.5mm (including 0.5mm) does not exceed 1000 per cubic foot of space.

[0026] d. The operator first puts the tray in the special fixture for the tray, and then puts it on the automatic cleaning machine. The system will automatically run according to the process.

[0027] e. The system first pre-c...

Abstract

The invention belongs to a cleaning method in the undefiled environment, in particular to a pallet cleaning process of a computer hard-disk fitting. According to the technical scheme of the invention, the cleaning process with the super cleanliness of the pallet comprises: a. goods shower: blowing off the particles on the pallet surface using the filtered wind; b. pre-cleaning: ultrasonic cleaning the pallet in the ultrasonic container; c. a first spraying: carrying out the first spraying after ultrasonic pre-cleaning; d. blow drying: after spraying, carrying out the blowing drying process of the pallet; e. oven drying: putting the pallet in the oven after blowing drying and drying the aqueous vapor on the pallet surface; f. packaging: putting the pallet under the 100-grade environment and packaging the pallet by the staff wearing undefiled clothes after the pallet is cooled to room temperature. By the method of the invention, the particles of the dead zone of the pallet are easy to clean, thereby greatly improving the cleanliness of the pallet surface.

Description

technical field [0001] The invention belongs to a cleaning method in a dust-free environment, in particular to a tray cleaning process for computer hard disk accessories. Background technique [0002] With the rapid development of electronic technology in today's world, the replacement cycle of computer hard disk products is becoming more and more frequent. As the world's largest supplier of computer hard disks, Seagate Corporation of the United States keeps updating its products, and at the same time puts forward higher requirements for the performance of product components, especially in terms of cleanliness. [0003] The traditional tray cleaning method is suitable for cleaning injection molding and blister trays. The cleaning principle is: pump high-pressure water from the water pump (the pressure is 50pis-80psi, the flow rate is 12GPM), and through the specially designed nozzle, a 45-degree fan-shaped water column is sprayed on the surface of the tray to wash down the ...
