What is FR4 PCB？
FR-4 is the most commonly used name in the printed circuit board industry. People inside and outside the industry who have a preliminary understanding of FR-4 believe that it is a printed circuit board material. There is no problem with the above statement, but in fact, FR-4 is more accurately a code used in PCB materials, mainly referring to the heat resistance level of the product. Therefore, the complete meaning of FR-4 is the material specification of the resin material that can self-extinguish when burned. It is a material grade, not a name. There are many FR-4 grade materials, which are also the most commonly used materials in the printed circuit board industry. No doubt Ulectronics is no exception, it also uses FR-4 materials. Traditional single-sided printed circuit boards, double-sided printed circuit boards, including multi-layer printed circuit boards, mostly using FR-4 level materials, materials mostly using TERA-FUNCTION epoxy resin, filler, glass fiber, etc., belong to composite materials.
As mentioned above, FR-4 has a very wide range of applications. Manufacturers, including Ulectronics, evaluate the main use of their products before manufacturing, and select different FR4 PCB material types according to the use and characteristics of the product. Such as insulation board, epoxy resin board, glass steel plate, FR-4 reinforced board, flexible circuit board reinforced board, flame retardant insulation board, FR-4 light board, PCB drilling pad, etc., are commonly used types. They all have some common advantages and characteristics that can be used in various types of products: first, the insulation is very good, which can effectively reduce the interference between components. Good flatness, smooth surface, no bump affect subsequent assembly and beauty. When applied to high-performance electronic products, the thickness can also meet the needs of the end product.
Regarding the common color of FR4 board, according to the years of production and cooperation experience of Ulectronics, different industries have different requirements for colors. The common colors are black, white, blue, yellow, red and so on. In general, special industries will use special colors. Many of our rail customers will choose red, while some sensor customers will choose blue, many controller customers will choose black and so on. FR-4 is just a sheet material. In addition to the substrate FR-4, according to Ulectronics experience, there are four types of sheet material, mainly classified according to the reinforcement material.

Waste caused by manufacturing defective products
As mentioned above, PCB is short for printed circuit board. It is the carrier of electronic components. All components are connected via PCB to achieve electronic functions. PCB assembly is short for printed circuit board assembly. It refers to the process of welding components to the PCB. PCBS and components have their functions, but they only work as fully functional products after they are all soldered together.
There is no minimum order quantity for PCB manufacturing in Ulectronics. By the way, Ulectronics focuses on low-volume to medium-volume PCBA service. Yet prototype PCB and mass production services are also offered.
We can consider providing free samples after an agreement has been reached on all aspects. For specific details, please contact our sales representatives. They will keep you informed of certain terms and conditions.

Types of FR4 Materials and Parameters
The name FR-4 with glass fiber epoxy copper-clad laminate is too complicated. We usually call it FR-4 copper-clad laminate or CCL. FR-4 type copper clad plate has excellent classification characteristics, and the quality is from high to low. According to different products, different grades of FR-4 type copper clad plate are selected. This can not only meet the needs of high quality, but also further ensure the cost performance of the product. In addition, it is especially important to know and understand our products. According to different product specifications and characteristics, choose the corresponding FR-4 copper clad plate grade, which can not only achieve the best quality, but also make the price in the most competitive position!
FR4 Performance advantages
Due to its wide range of applications, FR-4 has covered most electronic products well and its advantages are well known. For example, we know that FR-4 has good insulation, good heat resistance, and is not afraid of moisture. In addition to the excellent machining properties mentioned many times, FR-4 also has many advantages and characteristics in the processing process. Therefore, FR4 PCBS are widely used in many industrial fields. From a mechanical point of view, its scalability is very good. Whether it is in a high temperature and low temperature environment, or in an environment with different humidity, it can withstand various external forces. It can maintain good stability regardless of bending, stretching or impact. The loss coefficient is also very low, with a DF value of about 0.0024.
FR-4 is very adaptable. Whether it is a solid with a relatively low viscosity or a high melting point, FR-4 can be well adapted to meet the needs of the product. The curing temperature range is wide, from 0℃ to 180℃. FR-4 can be fixed at the required temperature of the product. The fixed temperature is very flexible and greatly facilitates manufacturing. The melting point of the platen is 203°. Therefore, the FR-4 printed circuit board can be used in high temperature applications such as power modules.
Shortening is very low. According to Ulectronics's production experience, it is usually less than 3% when curing, because there are no volatile substances during processing. Due to the presence of strong hydroxyl and ether bonds in the FR-4 material, it has good adhesion. In addition, due to the small intermolecular internal stress, the adhesion is further strengthened.
Good heat resistance. The heat resistance can reach more than 150°, so the product has a wide coverage and can be used in electronic products of all walks of life. The dielectric constant is very stable, about 2.34.
