Matte release film is the preferred isolation material for epoxy resin printed circuit processing, with high tensile strength and tear strength. The professional manufacturer of release film will explain to you the characteristics and characteristics of FPC copper clad plate and aluminum substrate laminated high-temperature resistant matte release film.

Using high-quality fiberglass yarn for plain weave or special weaving to weave high-quality fiberglass fabric, and then using unique process technology, fully immersing and coating imported PTFE (Teflon) resin, producing various thicknesses and ultra wide fiber high-temperature resistant coating fabrics.

Analysis of the causes of ten common problems in the production process of release film

There are many types of matte release films, including high gloss films, reflective films, coating films, anti-static films, etc. Do you know what classification PET release films are all based on? Let the release film manufacturer tell you.

Ruichangxing Barrier Release Film is a high-performance and high-temperature resistant resin barrier release film. The barrier release film is used in the circuit board pressing process. After special process design, it can be used to block multiple lamination processes such as burying holes and blind through-holes after resin overflow, with good adhesive blocking and plugging effects.

This includes preparing component libraries and schematics. Before conducting PCB design, it is necessary to first prepare the schematic SCH component library and PCB component packaging library. The PCB component packaging library should preferably be established by engineers according to the standard size data of the selected components. In principle, first establish a component packaging library for PC, and then establish a schematic SCH component library.

Generally, we choose green because it has little irritation to the eyes, and production and maintenance personnel are less likely to have eye fatigue and less eye damage when staring at PCB boards for a long time. Common colors include yellow, black, and red. Various colors are sprayed onto the surface after manufacturing.

Flexible Printed Circuit (FPC) is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film. It has the characteristics of high wiring density, light weight, thin thickness and good bending performance.

Single/double sided release film is mainly used for laminating adhesive products due to its excellent high-temperature resistance characteristics. The product uses PET as the substrate and is evenly coated with an extremely thin release agent on one or both sides. The release film surface is flat and smooth, and the coating is uniform, without defects such as wrinkles, particles, bubbles, etc.

In the process of producing release films, we will encounter various problems. Today, the editor of Shenzhen release film manufacturers will share with you the common problems encountered during the production process of release films.

There are many specialized terms in PCB circuit boards, and it is also necessary to know these terms. Here, we will explain some professional terms in PCB circuit boards.
