For a product, we not only need to know its usage method, but also the storage method, so that it can be directly stored when not in use. If the incorrect method is used, it will affect the quality of the product, and the release film is the same. So what are the usage and storage methods of the release film? 1、 Storage 1. Store in a ventilated space or a cool place, and the temperature range should be kept between 5 ℃ and 32.5 ℃ 2. Keep away from ignition sources and compatible materials: strong alkali, Mineral acid, ammonia, chloride, strong oxidant. 3. Keep the container tightly closed when not in use. four

What should I pay attention to when choosing an anti-static PET protective film? When users shop, they usually focus on quality and price issues. Therefore, when choosing a release film factory, they should also pay attention to the following questions: Do the manufacturers of the release film factory have their own production capabilities? This can generally be studied by studying the release film factory of this manufacturer, which can be seen from the quality and quantity of users. Due to the low sales volume of many small manufacturers in a year, they may shut down or close down at any time, which has a direct impact on after-sales work. The selling price of the release film factory does not meet the market price. At present, the selling prices of release film factories that are very common on the market are generally in the range

Transparent release film can be said to be a material that plays a significant role in the production of certain industries. Why do you say that? Because sometimes a film needs to be removed after a few processing steps when it is attached to the material, but the general film may be stuck on top and unwilling to be removed, which causes a lot of trouble. Transparent release film avoids this cool production, and the printed materials produced inside will use transparent release film. The surface of the transparent release film has undergone special treatment by adding a layer of material different from the film itself, which can avoid sticking to certain specific materials,

The root cause of expansion and contraction is determined by the characteristics of materials. To solve the problem of expansion and contraction of rigid flex joint plates, it is necessary to first introduce the flexible plate material polyimide:

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.
