Introduction Flexible Printed Circuit (FPC) is critical component in modern electronics. It enables compact, lightweight designs in devices like smartphones, wearables, and medical equipment. The delicate, multilayer structure, comprising conductive copper traces and insulating polyimide substrates, demands precise fab...

Metal domes are tiny, spring-like components found in devices, like remote controls, keyboards, and smartphones. They are the reason that you can feel tactile feedback when you press buttons. But how do you make sure these little parts work well every time? You want to choose good ones before installation. Let's ta...

Flexible Printed Circuit (FPC) has some advantages, such as high-density wiring, light weight, and thin thickness. It is widely used in many products, such as mobile phones, laptops, PDAs, digital cameras, LCMs, etc.. In recent years, PCB manufacturing technology has developed rapidly. People put forward higher require...

Plastic substrates are popular due to good stability, water resistance, softness and strength. They have various types. However, due to the features of plastic itself, there are some difficulties to printing. For example, in silkscreen printing, plastics are highly hygroscopic. They are easily deformed by the relative ...

The weaknesses of the material itself limit the design of flexible printed circuits. You must overcome hardening and fatigue of copper foil, keep good flexibility, and prevent tearing of FPC substrate. In order to produce reliable flexible printed circuits, there are something you should do, and something you shouldn&#...

15 things that improve accuracy when making screen 1. Mesh We are talking about the type of mesh we use, mesh count, fineness of mesh diameter, size of the opening area, expansion and contraction rate, weaving method, and color. 2. Screen frame They are material, size and strength. 3. Tension 4. Angle of mesh 5. Bondin...

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 ...
