Introduction to silver paste wiring

Silver paste circuit is an application of conductive silver paste. As a type of screen printing paste, conductive silver paste not only has excellent adhesion and coverage, but also has extremely low resistance value, greatly reducing the curing temperature. Widely used in fields such as electronic tags, film switches, printed circuits, etc.

                                                         

Generally speaking, the higher the conductivity requirements, the higher the silver content and the higher the cost. However, when pure silver printing is not necessary, mixed use can reduce costs. In recent years, with the rise of radio frequency identification (RFID), the use of silver paste lines for shopping has doubled. In response to market demand, Nanhuang Industrial recommends it to everyone, hoping to provide some reference value for friends in need. Silver paste electrode material is used to form the output electrode of an electrostatic capacitive touch panel through screen printing

Previously, the minimum line width for screen printing methods was 100 meters, and silver paste lines could be as fine as 50 microns In addition, as it is a material that can cure at low temperatures below 100 ° C, it can be printed not only on glass but also on materials such as plastic films.

The insulating material is used for electrode insulation film and is suitable for forming insulation film by photolithography. It can be combined with fine patterns such as stacked electrode intersections to form insulation film. Adhesive is used for bonding glass protective covers to touch panels, or for bonding touch panels to liquid product panels. Although the thickness between the layers of the glass protective cover, touch panel, and liquid product panel varies depending on the manufacturer, the new product is liquid, so compared to adhesive films, it can flexibly respond to changes in interlayer thickness. And the adhesive also has the characteristic of being able to be shaved off without damaging the surrounding components after bonding.

There are various types of silver paste. Conductive silver paste has stable performance, good printability, excellent adhesion and elasticity, and clear electric rain coefficient for road separation. Conductive silver paste is widely used in electronic components. The use of conductive silver paste reduces the production cost of electronic components and improves the stability of the components. The following is its related information.

The application of silver paste wiring: film switch, flexible circuit, dance blanket circuit, toy circuit, handwriting board circuit, electronic keyboard circuit, computer Jinpan Liquan Chuangwu use

The silver paste circuit has excellent conductivity, wear resistance, and disease resistance, making it easy to walk without any watermarks

The five characteristics of silver paste wiring:

1、 Excellent printability and antioxidant properties

2、 Extremely high conductivity originality document

3、 The extremely high Naiwei is studying agriculture on Hu 6118.com

What is the minimum standard for silver paste lines? Insulation resistance ≥ 5MG;

Design layers 1-4:

Carbon silver thickness 0 025-0.1mm:

Attachment strength 10 Nam: minimum line width ≥ 0.2MM: minimum line spacing ≥ 0.25MM: minimum pad inner layer ≥ 0.5MM: outer layer ≥ 0.8MM: anti click strength ≥ 1 million times: green oil bridge capacity ≥ 4 mil UV standard:

UV curing aperture tolerance 0.05mm: hole position tolerance 0.075mm: external tolerance 0.075mm; Printing area (0.5-160CM) 2: Test voltage DC 10-50V: Quality standard GB/T 4588. IPC-A-600F

Commonly used for manufacturers of calculators, password machines, perpetual calendars, telephones, learning machines, voice e-books, electronic keyboards, electronic calendars, electronic audio charts, dance mats, toys, car antennas, etc.

The silver paste circuit is made of non-conductive film

Printed with conductive silver paste or carbon paste on PET, and printed with non-conductive insulating oil to form a circuit board. Thin film circuits can be printed with pure silver or silver carbon mixed printing. The price of silver carbon mixed printing is lower than that of pure printed circuits, but the anode is larger and the conductivity is poor. Please refer to the customer's specific requirements.
