Lida for you to analyze the technical difficulties of etching network

The etching net hole products as well as a variety of products has been widely used in precision filtration equipment, chemical fiber spinneret, jet nozzle, computer print head baffle, printed circuit boards, TV, planetarium star orifice, aviation gyroscopic instrument components, aircraft turbine blade and the red blood cell filters in the medical equipment parts processing fields.

Divided according to the size of the hole range, so far, about more than 50 kinds, every kind of machining method has its advantages and disadvantages, it mainly depends on the size of the workpiece aperture, hole arrangement, hole density, hole accuracy requirement, and want to consider the subsequent use of artifacts, it comes to think about which one to use process can batch processing problem.

Zolida USES chemical etching process to process some mesh intensive, high tolerance requirements of mesh products have a very unique processing method.The hole wall after processing is hairless, with uniform pore diameter and good roundness.When such mesh products need to be mass produced, the etching process can also respond positively.Etching process needs to consider the problem of material thickness, in general, chemical etching mesh processing products, the use of material thickness is less than the aperture to be processed, if the thickness of material is greater than the aperture, the etching process is not suitable for processing.Because, at this point, because the chemical etching agent expansion can not meet the etching amount.

There is a wide range of technical difficulties in etching network products in the etching industry, that is, the phenomenon of blocked hole and blind hole, in this paper, the cause of this bad analysis to you, for you to etching network processing technical difficulties.Wall hole or blind hole phenomenon generally occurs in intensive network of etching processing products, due to the dense hole machining product aperture and subtle, the effect of the etch film was exposed film difficult to check, there will be a part of the exposure and development undesirable phenomenon, so there will be a part of the wall after etching hole or blind hole is undesirable.

It is usually scattered, the general plugging hole or blind hole rate will be around 5-8%, customers will also accept, if it is a large area of plugging hole or blind hole occurs that is bad production, is the customer can not accept, judged as bad waste.The reason for this kind of bad is the clean room level is not up to the established standards, dust adsorption into the ink produced bad.

Another problem is warped film problem, the so-called warped film is just a saying in the etching industry, that is, in the etching process, the area that does not need to be etched into the chemical potion caused by the surface micro-corrosion phenomenon, generally presenting a layer of white surface, a little rough.The cause of this phenomenon is generally the metal surface in addition to the oil is not clean led to photosensitive ink coating or photosensitive film adhesion decreased.

Zolida is a high-tech enterprise engaged in the research, development and production of precision metal etching components and SMT laser templates, and vacuum diffusion welding. Our products have passed ISO, quality and environmental management system certification, and have been widely recognized by a large number of customers for their exquisite technology and considerate after-sales service.Hotline:0513-81601668    182-0629-3159
