Abstract

PURPOSE:To form a gold film having overall uniform thickness, by a method wherein a plurality of gold film layers are so overlaid as not to be overlaid at the raised portions which are formed at the edges thereof by using screens of different printing width. CONSTITUTION:A first gold film 21 is formed by a method in which a gold paste is applied on the surface of an insulating substrate 1 through a first screen having the printing surface on the overall surface of an insulating substrate 1 and the burning process is applied thereon. A second gold film 22 is formed by a method in which a gold paste is applied on the surface of the first gold film 21 between the raised portions 31 of the both sides thereof through a second screen having the printing surface smaller than the first screen in width by the width of raised portions 31 formed at the both sides of the film 21 and the burning process is applied thereon. A third gold film 23 is formed by a method in which a gold paste is applied on the surface of the second gold film 22 between the raised portions 32 of the both sides thereof through a third screen having the printing surface smaller than the second screen in width by the width of raised portions 32 formed at the both sides of the film 22 and the burning process is applied thereon.

The present invention relates to a method for forming a gold film, and particularly relates to a method for forming a gold film using a screen printing method to form a thin gold film having a uniform thickness over the entire surface. [Prior art] Conventional film forming methods using gold paste include 1. For example, when manufacturing a thick film cedar thermal head, an inorganic gold paste is printed on an insulating substrate by screen printing, and then fired. Process? Repeat multiple times lj,! 35μm f!
It is common practice to completely form a gold thin film of i degree, and this gold thin film is photo-etched to form a double positive conductor with an i!4 pattern. 1-C gold particles, frit glass, and a binder such as a vehicle are mixed with a solvent and made into a paste. If the screen mark 1G, ]te is thinly marked 14ilI once, gaps will be created between the gold particles, so the firing process is

[Nate alms 1%j sa 3.511m Ff! A thin gold film was completely formed. Figure 3 is a cross-sectional view showing the thickness of each part of the gold thin film formed by the conventional film forming method described above. (Color 1 is a flexible substrate, (2) is a gold thin film, and this example is a three-layer gold thin film with υ
. (a), and the CO is the first screen mark formed in the first screen mark (51j,・suε formation process).
``7!t;y *tsu is the second gold thin film formed during the second screen printing and firing process, c13 is the third gold thin film formed during the third screen printing and firing process. (3) is the part 919 formed on the peripheral edge of the insulating substrate (1), and (G]), (2), and (g) are the first, second, and third gold thin film sheets, respectively. The rising part formed at υ, (A), and c23 is formed in a sequentially stacked manner and is about 1.5 times thicker than the central area.In this way, it may be one peripheral part. The reason for this is that when gold paste is applied using a squeegee, the gold paste is thicker at the periphery of the screen and thinner at the center area.
A pool of gold paste is formed at the peripheral edge, and this is fired to form the raised part. [Problems to be Solved by the Invention] As described above, when an electrode conductor is formed by photoetching with a thick gold thin film at the periphery, gold tends to remain between the patterns at the periphery, resulting in pattern short defects. In order to correct this, it was necessary to perform a photo-etching process multiple times. This invention was made to solve the problem of non-uniformity in the thickness of the gold thin film. The object of the present invention is to obtain a method for forming a gold film that can form a thin gold film that does not bulge up at the peripheral edge. [Means for Solving the Problems] The present invention uses screens in which the vertical and horizontal sizes of the printing surfaces are different by a predetermined length, and the vertical and horizontal edges do not overlap. This is a gold film forming method in which each screen is positioned at a position shifted by a predetermined length, and gold paste is printed and fired. [Function] The vertical and horizontal sizes of the printing surface of the screen on which the gold paste is applied multiple times are made different by a predetermined length, and the predetermined length is set so that one peripheral edge does not overlap when printing. Zu? Since the position is shifted,
Since the 9 parts of the periphery of the gold thin film of each layer do not overlap and are dispersed appropriately, the bulging of the periphery of the formed gold thin film is small and the difference in thickness is small over the entire surface of the gold thin film. can be formed. [Example] FIG. 1 is a cross-sectional view showing an embodiment of a gold thin film formed according to an example of the present invention. In fig. The first gold thin film e2 is formed by applying gold paste using a first screen that uses the entire surface of the insulating substrate (1) as a printing surface, and then performing a firing process. (A) is the second gold thin film, which is formed on the surface of the first gold thin film t21) at the edges of both sides of the first screen, and has a width smaller than the width of the 919 portion 0]). Gold paste is applied onto the dark side of the 919 portion C31) on both sides using the second screen formed on the printed surface of , and a firing process is performed. 4 is a third gold thin film, which is formed on the surface of the second gold thin film block with a printing surface having a width smaller than the width of the raised portions (2) on both sides of the second screen 91. Using a screen, apply gold paste on the surface between the 919 parts (2) on both sides. It is formed through a firing process. In this way, the first to third gold thin films/2D, (a), (
to). Using the 1st to 3rd screens whose printing surface widths were successively narrowed, they were overlapped so that 03 did not overlap and at a predetermined shifted position. When the thin film p, ■, (23 is formed, the 919 parts 6υ, (to), (to) do not overlap even though they are formed at each edge part, so the thickness of the gold thin film (23) is uniform as a whole. ) can be formed. FIG. 2 is a sectional view showing an aspect of a gold thin film formed according to another embodiment of the present invention. 2. Third thin gold film? Sword,
Using screens with wider widths in the order of (A) and @,
The 919 portions 01), (a), and □□□ of each gold thin film were formed so as not to overlap. Even if you do this,
As in the previous embodiment, it is possible to form a thin gold film (2) having a uniform thickness as a whole. In the above examples, the gold thin film (2) was formed by coating and firing three times, but the invention is not limited to this example, and the thickness of the gold thin film to be formed Apply the coating and firing process as many times as necessary (for example, when forming a thin gold film twice the thickness of the actual example described in Section 2), apply the coating and firing process as many times as necessary. Gold thin 1st copy t21) , (c)
After forming the edges, layer them one on top of the other and use the same procedure to form the first, second, and so on. By performing the third gold thin film C), (a), and (transfer) gold forming steps, the entire gold thin film can be formed to have a uniform thickness and double the thickness. [Effect of the invention] This 56-metal gold base was coated on the surface of the FC insulating substrate using a screen kumquat and a squeegee, and then baked to form the entire gold thin film. This film forming method is characterized by using screens of different widths to prevent the rising part of the gold thin film formed on the edges from crossing over. , the film JV as a whole is formed into a homogeneous gold thin layer.
