JPS63154985A - Dial for wrist watch - Google Patents

Abstract

PURPOSE:To improve appearance and yields, by a method wherein a water soluble printing ink is used and undergoes remasking and reetching to remove pinholes due to dirt, dust and the like. CONSTITUTION:In the peeling of a resist, the resist is immersed into a thinner and brushed for 15sec or so. Here, dirt, dust and the like adhering to the surface of the resist are left as resist foreign matter like a pattern during the exposure to light and as etching foreign matter after the etching treatment, which poses a cause of poor appearance. To solve this problem, a water soluble ink is printed by means of a screen or a pad printing machine. Drying is of a force type at the normal temperature. Here, be sure to eliminate pinholes and thereafter, a second etching treatment is conducted. After the etching treatment, the time setting is the same as the first operation. In the separation of ink, the ink is immersed into a thinner or alcohol and brushed for 15sec or so. The appearance thus finished is without etching foreign matters as illustrated thereby improving manufacture and yields.

Finishing is Polyplastic 103), and then a Cr vapor-deposited thin film (1400 people) and an Au vapor-deposited thin film (1400 to 1600 people) are applied on the coating film using Cr metal to express silver and all color tones, respectively. Then, the photoresist solution was mixed with Cr, A
Apply thin film (film thickness: 1 to 2 μm) and then pre-dry (80° C. for 20 minutes). Patterns such as letters and patterns are formed using a mask film (thickness: 115 μm) with an exposure time of 5 to 6 seconds. Next, development is performed for 145 seconds using a resist exclusive solution, and the resist solution other than the one that has been patterned by exposure is removed. Further, using a special etching solution, the deposited thin film other than the part for forming the pattern is removed by etching to reveal the pattern (FIG. 1). Dip the resist peeler in thinner, wash the brush for about 15 seconds, and then remove the resist. At this time, dirt, dust, etc. adhering to the resist surface will remain on the resist as well as the pattern during exposure, and will remain on the resist during the etching process, causing poor appearance. Therefore, the water-soluble ink of the present invention (product name: Sericol FM-016. Manufacturer Teikoku Ink) was screened,
Or print with an octopus printing machine.

minutes). At that time, make sure to eliminate all ink pinholes. Thereafter, a second etching process is performed using the same etching solution and time as in the first process. The ink peeler is soaked in thinner or alcohol, and the brush is cleaned in about 15 seconds to remove the ink. Therefore, the finished appearance is as shown in Figure 1, with no etching residue left on the dial decoration and texture.
We were able to express novelty and further improve the manufacturing method and yield.
