A method for manufacturing a microelectronic package (1) comprises the steps of providing two parts (13, 14) comprising electrically insulating material such as plastic; providing members (21, 22, 23) comprising electrically conductive material; providing a microelectronic device (30); positioning the electrically conductive members (21, 22, 23) and the microelectronic device (30) on the electrically insulating parts (13, 14); and placing the electrically insulating parts (13, 14) against each other, wherein the microelectronic device (30) and portions of the electrically conductive members (21, 22, 23) are sandwiched between the electrically insulating parts (13, 14). The electrically conductive members (21, 22, 23) are intended to be used for realizing contact of the microelectronic device (30) arranged inside the package (1) to the external world. An important advantage of the method having steps as mentioned is that the electrically conductive members (21, 22, 23) as such are provided, wherein it is not necessary to provide a conventional lead frame which has the disadvantage of causing considerable waste of metal material during its manufacturing process.

The invention discloses a folded teaching tool of an ink and wash painting. The folded teaching tool of the ink and wash painting comprises a piece of painting paper, a brush, ink and an ink absorber. The painting paper is a rectangular hard board with a smooth and flat upper surface. The upper surface of the hard board is covered with a waterproof layer. A plurality of uniformly distributed small-bore pits are formed on the upper surface of the waterproof layer. A guide groove is formed in the inner wall of a rib. A through groove penetrating through the rib is also formed in the rib. The guide groove is communicated with the through groove. An open-close door is formed on the through groove. The hard board is connected with a second hard board. A second waterproof layer is arranged on the second hard board. The second hard board and the hard board are arranged back to back. The outline size of the second hard board is identical with that of the hard board. The second hard board is connected with the hard board through a hinge. The ink absorber comprises a housing, a fan in the housing and a battery in the housing. A fan cavity for accommodating the fan, a battery cavity for accommodating the battery and an ink absorption channel connected with the fan cavity are formed in the housing. The invention provides the folded teaching tool of the ink and wash painting.

The invention relates to the technical field of dust removal equipment, in particular to a dust removal device. The water tank is provided with an exhaust port and a water injection port, and the lower part of the water tank is provided with a sewage discharge port. The air distribution pipe, the air distribution net, the adsorption net and the air flow sieve plate are arranged in sequence from bottom to top; The mesh of the cloth has an adsorption area composed of adsorption nets above the air distribution net. The adsorption nets are divided into upper and lower layers. The two layers of adsorption nets are supported and connected by a support frame; The sieve holes of the airflow sieve plate are evenly distributed cylindrical sieve holes and penetrate up and down through the airflow sieve plate; the shapes of the air distribution net and the airflow sieve plate match the cross-sectional shape of the water tank, and the air flow sieve plate is placed in the water tank in a movable manner. The water port is arranged above the water tank. It has the advantages of simple structure, easy maintenance and high dust removal efficiency.

This application discloses an AAA high-concurrency authentication method and system. The method is introduced into the Netty server, and the authentication information sent by the terminal device is forwarded to the AAA authentication server through Netty. The authentication module is based on the authentication information and the historical authentication information in the Redis cache. Authenticating the terminal device; and updating the historical authentication information in the Redis cache. Netty's IO thread NioEventLoop can process hundreds or thousands of client Channels concurrently due to the aggregation of the multiplexer Selector. Since the read and write operations are non-blocking, this can fully improve the operating efficiency of the IO thread and avoid due to The thread suspension caused by frequent IO blocking does not need to waste CPU resources for switching between threads, and can solve the technical problem of network packet loss in the existing AAA authentication technology. In addition, Redis caches information to reduce disk IO and improve authentication efficiency.
