Ink is important material for printing. Its performance directly has an impact on printing quality and production efficiency. Let's talk about ink viscosity. Rheology Rheology is the science of deformation and flow of materials. Ideal elastic bodies and ideal viscous materials do not actually exist. The deformation...

In the 1980s, when organic conductors and semiconductor materials were discovered, people saw the hope that information electronic devices in the future might be manufactured through printing. This is because organic materials can generally be prepared in solution form, giving them the features of printing inks. Theref...

Relief printing Pattern of relief printing is raised, and the blank part without pattern is concave. There is a certain height difference between these two parts. In order to evenly apply the ink on surface of screen, the raised pattern should be on the same horizontal plane. For curved screens, the raised part should ...

Surface mount technology (SMT) is one of the core technologies of modern electronic manufacturing. It leads to efficient and accurate component placement and welding operations, thereby improving product quality and production efficiency. Production process 1. Making stencil Here is the preparation of surface mount tec...

Surface Mount Technology (SMT) is the processing technology that directly mounts electronic components on printed circuit boards. It adds traditional plug-in components on PCB surface, thus avoiding connecting component pins with PCB drilling holes in traditional processes. SMT reduces production time and production co...

Silver conductive paste enables microelectronic devices to work stably under normal temperature and humidity. Silver conductive paste is screen-printed on a substrate to form circuit pattern with a thickness of several microns to tens of microns. Then, through processes such as drying and sintering, the bonding phase p...

In-Mold Electronics (IME) is the extension of In-Mold Decoration (IMD). Thermoformed plastics with decorative coatings are transformed into 3D components by injection molding. IME is the development of existing technology, so much of existing processes and equipment can be reused. Compared to technology on traditional ...

In-mold electronics (IME) is a combination of in-mold decoration (IMD) and printed electronics. It is an alternative to traditional human-machine interfaces (HMIs) with mechanical switches. IME has strong functionality, light weight and lower cost. It has wide application in automotive, medical devices and household ap...

There are three popular materials for graphic overlay: PC, PVC and PET. There are two surface types, matte and glossy. PC has good physical and chemical properties. It is suitable for a wide range of inks. PC is the most commonly used material for graphic overlays. It is available for matte and glossy surfaces. People ...

Tempered glass Tempered glass is a kind of prestressed glass. To improve the strength of ordinary glass, people use chemical or physical methods to form compressive stress on glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enha...

The assembly and welding process of FPC is very different from that of rigid PCB. FPC is not hard enough. If you don't use a special carrier, it is impossible to complete fixation and transmission. It is also hard for SMT processes, such as printing, patching, and furnace passing. 1. Pretreatment FPC is usually not...

The holes of FPC can be drilled by CNC like PCB. With high density of circuit, small aperture of metallized holes and the fact that the aperture of CNC drilling has a certain limit, many new drilling technologies have been put into use. They are plasma drilling, laser drilling, punching of small apertures, chemical etc...
