Due to the increasing popularity of advanced manufacturing technologies, it has become easy to achieve the smallest PCB size. Although PCB manufacturers have experimented with a variety of sizes, materials, and technologies, they also rely on Gerber files to oversee the production of printed circuit boards.

The conduction function of the panel keys and the reliability of the conductive circuit depend on the use of functional inks and other treatment measures. Functional inks used in panel keys mainly include conductive silver paste, conductive carbon paste and insulating ink.

The printed circuit board design process includes drawing circuit schematics, planning printed circuit boards, component packaging, component layout, automatic wiring, manual adjustment, saving output, etc.

Quality inspection of membrane switches is a very important task. The first task of a successful membrane switch manufacturer is to establish a complete quality assurance system.

The general machine uses a variety of models, functions of integrated circuits (ics), and several large or very large scale integrated circuits as the core, with other integrated circuits and discrete parts circuit, to form the circuit of the whole machine. These core integrated circuits may contain the functions of one or several system circuits.

The membrane switch panel is a switch made by printing a contact circuit with a conductive paste on a flexible polycarbonate or polyester film. It is a type of contact switch. The membrane switch panel is a flat type, multi-layer combination and sealed structure. It is an assembly of an electronic complete machine operating system that integrates key switches, panel function markings, reading display transparent windows, indicator light window holes and circuits.

PCB wiring refers to laying electrical roads to co-sign components. In PCB presets, wiring is the closing step to complete the preset product. What are some common rules for PCB wiring.

Membrane panel the membrane layer is an integral part of the membrane switch, which can clearly display the function, color, type, operating position and protection function of the switch.

The four-layer circuit board can be divided into a top layer, a bottom layer and two intermediate layers. General Principles for Layout and routing of multi-layer PCB board The general principles that PCB designers need to follow during the circuit board routing process.

There are many raw materials used in the manufacture of membrane key panels. In addition to film materials and inks, another widely used material is double-sided tape. Double-sided tape is one of the most widely used raw materials in the membrane key panel panel industry. Among the double-sided tapes, 3M brand double-sided tapes play an important role in the double-sided tape industry.

The membrane switch factory will use a lot of production processes in the production process, such as laser engraving process, silk screen printing process, stamping process, etc. Here we want to talk about the stamping process.

In order to ensure the production quality of PCB board, the manufacturer has gone through a variety of detection methods in the production process, and each detection method will target at different PCB board defects.

The typical process of PCB multilayer circuit board processing is "graphic plating method". That is, a layer of lead-tin corrosion resistance layer is pre-plated on the copper foil part that needs to be preserved on the outer layer of the board, that is, the graphic part of the circuit, and then the other copper foil is corroded by chemical methods, which is called etching.

Membrane switch is an electronic component, which is a part of instrumentation. It is a product that integrates functionality and decoration realized by screen printing process.It is widely used in machinery, automation, instrumentation, medical instruments, etc. industry.

The PCB forms a connection between the point and the printed element according to a predetermined design on the general substrate. The main function of this product is to make various electronic components form a predetermined circuit connection, play the role of relay transmission, is the key electronic interconnection of electronic products, known as the "mother of electronic products".

The instruments of different cars are different, all of which are film panels, but the conventional instruments of general cars include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc.
