As the raw material for silkscreen printing, ink requires the features of wear resistance, high temperature resistance and easy mixing. There are two types: solvent-based ink and light-curing ink. Solvent-based ink After silkscreen printing with solvent-based ink, plastic pieces needs to be dried in a three-stage dryer...
1. Tension meter Tension meter is an instrument that measures the mutual traction between the contact bodies of mesh when the mesh is subjected to tension. There are two types of tension meters: mechanical and electronic. The unit of tension measurement is N/cm. Tension can also be expressed in relative values. Centime...
Automobile technology is developing rapidly. People want good driving experience. We also pay attention to in-vehicle display system. At present, most of the in-vehicle screens are LCD screens. Due to the special use environment of in-vehicle displays, the screen is generally required to be moisture-proof, dust-proof, ...
Something you need to know In silkscreen printing, people want customized colors. Color mixing is an important step. The basic principles of it are the subtractive color principle of colorants and the additive color theory of colored light. To get the correct color, ink mixing should be done under stable natural light,...
Is the gap necessary? There should be a certain gap between screen and substrate. The mesh is stretched on screen frame. When the screen is in a horizontal state, there will be a certain sag. Especially during the scraping process, the sag will increase. To prevent the substrate from sticking to the ink before scraping...
1. Features Compared with gravure printing and offset printing, there are some features of multi-color silkscreen printing. It has very strong expressiveness, bright colors and good 3D sense. It has light resistance and drug resistance. It's popular because of durability, long-lasting use, and no fading, especially...
Doing a good job of preparation before silkscreen printing is essential. Let's talk about some of them. Clean the printing site, and ensure that there is enough space around the printing machine to avoid something that interferes with the production. Keep the place clean to avoid dust and other things that affect p...
Inaccurate printing position Even if there are no problems with the screen size and printing machine, the inconsistency of the shape of the printing material will cause inaccurate printing position. For example, in paper color printing, after one color is printed and dried, the temperature changes, causing the size to ...
Electromagnetic interference (EMI) is something generated by the power supply, which affects the circuit through electromagnetic induction, electrostatic coupling or conduction. EMI can significantly degrade the performance of FPC, or even make it unable to work properly. Radio frequency interference (RFI) refers to th...
Preparation 1. Choice of ink When choosing right ink for silkscreen printing on acrylic, high-gloss, scratch-resistant ink is what we want. Don't use matte ink when printing on the surface, because it is not resistant to friction. The color is duller than that of glossy ink. It's not bright enough. 2. Choice of...
Flexible printed circuit (FPC) has the advantages of high line density, 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 has developed rapidly, and people put forward higher requirements for FPC. Prec...
Nowadays, we pay attention to quality management of flexible printed circuit (FPC). It is the fundamental way to eliminate defective products. So how to do it well? Let's dive in. 1. Manufacturing staffs We are talking about the personnel responsible for manufacturing. They are supervisors, production personnel and...
