Embodiment 1

[0019] Aluminum foil with a thickness of 0.01mm was selected and produced according to the following steps to obtain figure 1 The shown outer diameter is 3mm, the number of mesh holes is 600 mesh, and the mesh is an aluminum foil mesh with square holes.

[0020] The first step (1) is drawing: first draw manually according to the requirements of the required aluminum mesh, then transfer the manual drawing sketch to the computer for accurate drawing, and then print out the black and white negative film at a ratio of 1:1; form a sheet on the negative film The picture opposite to the real aluminum mesh is also called the positive and negative film, which is used as the target for making the real thing.

[0021] Step (2) is aluminum foil treatment: the surface of the aluminum foil is cleaned and dried with an ordinary kitchen fume cleaner; the ordinary kitchen fume cleaner is purchased from Beijing Lvsan Chemical Co., Ltd., and its model is Q / HDLSH008.

[0022] The (3) step is glu...

Embodiment 2

[0032] Select an aluminum foil with a thickness of 0.05mm, and make it according to the following steps to obtain figure 2 The outer diameter shown is 3.05mm, the number of mesh holes is 100 mesh, and the mesh is an aluminum foil mesh with round holes.

[0033] The first step (1) is drawing: first draw manually according to the requirements of the required aluminum mesh, then transfer the manual drawing sketch to the computer for accurate drawing, and then print out the black and white negative film at a ratio of 1:1; form a sheet on the negative film The picture opposite to the real aluminum mesh is also called the positive and negative film, which is used as the target for making the real thing.

[0034] Step (2) is aluminum foil treatment: the surface of the aluminum foil is cleaned and dried with a kitchen super fume cleaner; the ordinary kitchen fume cleaner is purchased from Beijing Lvsan Chemical Co., Ltd., and its model is Q / HDLSH008.

[0035]The (3) step is gluing: ...

Embodiment 3

[0045] Select an aluminum foil with a thickness of 0.02mm, and make it according to the following steps to obtain image 3 The shown outer diameter is 3mm, the number of mesh holes is 200 mesh, and the mesh is aluminum foil mesh with honeycomb holes.

[0046] The first step (1) is drawing: first draw manually according to the requirements of the required aluminum mesh, then transfer the manual drawing sketch to the computer for accurate drawing, and then print out the black and white negative film at a ratio of 1:1; form a sheet on the negative film The picture opposite to the real aluminum mesh is also called the positive and negative film, which is used as the target for making the real thing.

[0047] Step (2) is aluminum foil treatment: the surface of the aluminum foil is cleaned and dried with a kitchen super fume cleaner; the ordinary kitchen fume cleaner is purchased from Beijing Lvsan Chemical Co., Ltd., and its model is Q / HDLSH008.

Abstract

The invention provides an aluminum foil mesh for a transmission microscope and a scanning microscope. The thickness of the aluminum foil mesh is from 0.01 mm to 0.05 mm and the number of mesh holes is from 1 mesh to 600 meshes. A production method of the aluminum foil mesh comprises drawing, aluminum foil processing, performing photoresist, pre-baking, performing exposure, developing, rinsing, post-baking, etching and removing of photoresist. The production method of the aluminum foil mesh for the transmission microscope and the scanning microscope has the advantage of enabling obtained mesh holes of electron microscope aluminum foil meshes to be clear and hole walls of the electron microscope aluminum foil meshes to be smooth.

Description

technical field [0001] The invention relates to an aluminum foil net used for a transmission microscope and a scanning microscope and a manufacturing method thereof. Background technique [0002] After 1975, in the field of electron microscopy in China, metal grids were developed, such as copper grids, nickel grids, stainless steel grids, molybdenum grids, and tungsten grids; aluminum grids were successfully developed for the development and special needs of materials science research. . The main function of the aluminum mesh is not to interact with other metal elements in the experimental analysis and research. [0003] At present, the Chinese patent application (publication number: CN101866803A) discloses a transmission electron microscope microgrid, which is the closest prior art, and it specifically discloses that the microgrid 10 includes a carrier 110, a carbon nanotube support 120 and a fixed body The material of the carrier 110 (that is, the aluminum foil mesh) can...
