![]() ![]() On the other hand, it has disadvantages such as being difficult to coat uniformly and the contours being prone to bleeding. Its advantages are the rich variations of photosensitive materials that can be used as well as the high durability after printing. This is a method of directly coating the photosensitive material on the screen by using a type of trays called bucket, a coating machinery or the like. Screen printing can be said to be a printing method that meets the needs in the manufacturing of electrical and electronic components, as seen in how it has enabled the printing of fine wiring to the degree of just 10μm (the diameter of a single human hair is 60 to 80μm) through technological advancements in recent years.īroadly speaking, there are two methods of coating the photosensitive material on the screen mesh. In addition, any ink can be used as long as it is in paste form, so the ink components can be designed and selected relatively freely. Screen printing can be used regardless of the printing object, so it can even be used on base materials that are slightly uneven. Although printed electronics employs various printing methods, such as offset printing, gravure printing and ink jet printing, screen printing is particularly a method that is frequently used due to its characteristic of “being able to be used on many kinds of material.” Printed electronics is a technology that forms electronic circuits, devices and the like by using printing technology. ![]() Amid an ever increasing need for price reduction, miniaturization and weight saving in the electronics industry in recent years, a technology called printed electronics is gathering attention. ![]()
