Problems solved by technology

Especially in the production process and in the product testing process, the film system design and manufacturing process are not easy to coordinate, so that the control of product quality in production is not timely and accurate, which affects the yield; , so that the production time of the product is too long, so that the production efficiency of the equipment is not high; in the pre-melting process of the film material, the melting time is too long, and the effect of the melting material is not good, which seriously affects the Production efficiency and product quality of optical filters
The above-mentioned problems have not been effectively solved in the industry.

Embodiment Construction

[0028] The present invention is further described below in conjunction with accompanying drawing:

[0029] The production method of this technological process is perfect to complete the production of the product. In order to resolve the technical difficulties in the actual operation details. This process generally includes the following important links: substrate→polishing / cutting→ultrasonic cleaning before plating→plating of IR film→testing link→cutting→post-plating ultrasonic cleaning→inspection link→finished filter

[0030] The most core and key links are ultrasonic cleaning and IR film plating, which affect the final yield and product quality of the entire production process. In addition, ultrasonic cleaning before coating is added before coating, so that the substrate before coating is free from scratches, stains and dust; thus ensuring that the good product of the substrate before coating is close to 100%, greatly reducing the generation of bright spots under the coatin...

Abstract

The invention relates to a producing technology process for high performance IR-CUT filter that includes the following steps: cutting basal piece to mold basal piece and removing the silica oxide in polishing process, taking ultrasonic wave cleaning to the basal piece before coating, and taking R film coating, detecting, cutting, ultrasonic cleaning after coating, and detecting processes. The invention could effectively solve the film design and manufacturing technology consistency. It could decrease the coating layers.

Description

【Technical field】 [0001] The invention belongs to a production and processing technology of a filter, in particular to a production process applied to a high-performance IR-CUT filter. 【Background technique】 [0002] Although optical communication technology started earlier, it has only entered metropolitan cities in recent years due to the development of the Internet, which has greatly increased the demand for optical communication components. If you want to stand out in this industry, you must not only grasp market consulting and new product trends, but also It is necessary to master the changes in process technology (changes in film types, changes in equipment and changes in coating technology) to achieve high performance and high yield of products in mass production. The IR-CUT filter can correct the color of visible light and is used in image tubes, CCD / CMOS, digital cameras and mobile phone cameras to prevent false colors and ripples caused by the pixel spacing of the ...
