G10 FR4 Fiberglass Epoxy Composite Laminate Sheets

 

FR4 G10 epoxy board is a kind of high polymer that can be used in medium temperature environment. It is also a typical insulating material. Its main component is epoxy resin, so it will generally show heat deformation at a high temperature of 180°C. In order to ensure its integrity, it is generally not heated together with other metals.

In addition, we must also pay attention to whether it is toxic. Although the raw materials used in manufacturing are non-toxic, whether the products produced are toxic or not depends on the manufacturing process. When using epoxy resin to make various products, Other substances or solvents may be added to make the performance of the epoxy resin itself changed and become toxic.

Epoxy resin is generally used together with additives. According to the different additives, it can be judged whether the products are toxic. Generally, the main additives of epoxy resin are curing agent, modifier, filler, diluent, etc., which determine whether the product can be molded and cured.

  Therefore, the product cannot be confused to determine whether it is toxic. Depending on the manufacturing process, the added substance, and the qualification of the manufacturer, the quality of the product is also different. In the actual purchase of this type of product, the specific description of the product should be carefully checked to see whether it has the use of special substances, and the qualification of the manufacturer should also be investigated.

It is well known that FR4 G10 epoxy board is a commonly used insulating material with a wide range of uses. It can be processed into transformer parts, switchgear insulation parts, electric furnace insulation parts, and semiconductor insulation parts.



Is fr4 g10 a composite material?

  Composite materials refer to new materials made up of two or more materials. One of the materials is used as the matrix, and the other is used as the reinforcing material. In terms of performance, complement each other. It is indeed a composite material, its matrix material is glass fiber, and the reinforcing material is epoxy resin. After the glass fiber is pre-impregnated with resin, layer by layer according to the specified thickness, and then pressed and solidified. Although glass fiber alone has high strength, it is easy to bend and has good ductility when mixed with resin. Of course, some additives are added during manufacturing. For example, adding a curing agent can speed up the curing of the resin, and adding a stabilizer can ensure that the epoxy resin will not be decomposed due to high temperature during processing, assembly and use. The flame retardant can Make the material extinguish fire by itself, increase the sex.

  Therefore, as a composite material, it has good performance, high temperature resistance, chemical corrosion resistance, light weight, high strength, insulation, fatigue resistance, etc., and it can work normally in harsh environments. It has the following advantages:

  Advantage 1: Avoid the undesirable phenomenon of delamination and deformation of the plate. The appearance of FR4 G10 epoxy board under high temperature conditions is prone to deformation, which affects the appearance of the board, and some of the board has various phenomena. But its high temperature resistance can avoid the above situation.

  Advantage 2: To avoid the impact of the performance of the board. High temperature not only affects the appearance of the board, but also has a certain impact on the performance of the board, which may cause the performance of the board to be damaged.

  Advantage 3: Increase the service life of the board. The influence of various unfavorable conditions on the board is avoided, so that the aging of the board can be delayed, people's replacement time is saved, and the production efficiency is improved.

The polishing treatment methods for alumina ceramics

  It has become very common for thick film integrated circuits to use   alumina ceramics . Ceramic materials mainly made of alumina (Al2O3) have good conductivity, mechanical strength and high temperature resistance. It is a widely used ceramic at present. ​ However, after the alumina ceramic is sintered and cooled, it does not mean the end of product processing. Some products do not meet the application requirements. Therefore, they need to be processed, such as size correction and polishing. The polishing treatment method of alumina ceramics is as follows: 1. Using laser processing and ultrasonic processing for grinding and polishing. 2. Use Al2O3 powder or diamond paste for grinding and polishing. 3. The method of glazing is required (suitable for products that require high surface smoothness). 4. Use diamond, silicon carbide, etc. harder than alumina to grind step by step from coarse to fine. 5. The surface of the material is processed by ion implantation. Ion implantation...

The solution of bubble issue during injection molding process

  According to the causes of bubbles, the countermeasures are as follows: (1) When the wall thickness of the product is large, the cooling speed of its external surface is faster than that of the central plastic part. Therefore, as the cooling goes on, the resin at the central part shrinks and expands towards the surface, resulting in insufficient filling at the central part. This condition is called a vacuum bubble. Solutions mainly include: A) Determine the reasonable gate and gate size according to the wall thickness. Generally, gate height shall be 50% ~ 60% of the wall thickness of the product. B) Until the gate is sealed, a certain amount of supplementary injection material is left. C) The injection time should be slightly longer than the gate sealing time. D) Reduce the injection speed and increase the injection pressure; E) Use materials with high melt viscosity. 2) The bubbles caused by the production of volatile gases are mainly solved as follows: A) Sufficient pre-drying...

The application range of sandblasting treatment

Sandblasting is the process of cleaning and roughening the substrate surface by the impact of high-speed sand flow. Use compressed air as the power to form a high-speed jet beam to spray the blasting material (copper ore, quartz sand, corundum, iron sand, Hainan sand) at high speed on the surface of the workpiece to be processed, so that the appearance or shape of the outer surface of the workpiece surface changes. (1)  Workpiece coating and sandblasting before workpiece bonding can remove all dirt such as rust on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece (the so-called rough surface). By changing the abrasives with different particle sizes, the roughness of different degrees is achieved, which greatly improves the binding force of the workpiece with coatings and plating materials. Or make the adhesive bond more firm and better quality. (2)  The rough surface of the casting, the cleaning and polishing of t...
