When the PCB design is correct, components and printed boards are good, there may still be some problems with surface mounted technology (SMT). There can be something wrong during solder paste printing. What can affect assembly and soldering? Printing position (printing accuracy), the amount of solder paste, whether th...

Inkjet printing is a contactless, pressureless technology. It has the common features of digital printing with no screen. Silkscreen printing needs screen that is mesh-shaped. During printing, the ink on screen leaks from the through-hole of screen surface to the substrate under extrusion of the squeegee, thus finishin...

Thermal-transfer printing is ideal for large, bright patterns that print from edge to edge. The printer allows ink particles to transfer easily and create a lasting effect on fabric fibers. On the other hand, silkscreen printing is ideal for producing high-density patterns on a variety of materials. It is more suitable...

1. Leveling property During printing, if the ink has good leveling properties, the glossiness will be good. If the ink has poor leveling properties, it will be easy to draw, and the glossiness will be poor. 2. Fluidity The greater the fluidity of the ink, the larger the print size, the larger the dots, the thinner the ...

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...

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...

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...
