Impact Of Thickness And Specification On Price Of FR4

In the electronics manufacturing industry, FR4 materials are popular for their excellent electrical properties, mechanical properties, and heat resistance. FR4 sheet, an important form of this material, is priced according to a number of factors, the most notable of which are the thickness and size specifications of the sheet. In this article, we will explore in detail the relationship between FR4 sheet price and thickness and size specifications, and how this price range affects the market.

First of all, we need to understand the basic characteristics of FR4 sheet.FR4 sheet, known as glass fiber reinforced epoxy resin sheet, is an insulating material widely used in the manufacture of circuit boards for electronic products. Due to its good electrical properties and mechanical strength, FR4 sheet occupies an important position in the electronics industry. However, different application scenarios have different requirements for the thickness and specifications of FR4 sheet, which directly affects its price.

In the FR4 sheet market, the price is usually divided according to the thickness and size specifications of the sheet. Generally speaking, FR4 sheet has a wide range of thickness, from 0.2mm to several millimeters. The size specifications, on the other hand, are customized according to the customer's needs, ranging from a few centimeters to several meters. With the increase of thickness and specifications, the price of FR4 sheet also shows an upward trend.

Specifically, when the thickness of FR4 sheet is thinner, its production cost is relatively low because raw materials are less consumed and processing is less difficult. As a result, the price of thinner FR4 sheets is typically lower. However, as the thickness increases, the consumption of raw materials and the difficulty of processing also increase, resulting in higher costs and higher prices. In addition, FR4 sheets of different thicknesses differ in electrical properties and mechanical strength, which also affects their price.

In addition to thickness, the size and specification of FR4 sheet is also an important factor affecting the price. Smaller FR4 sheets are more convenient in the processing and transportation process, so the cost is relatively low and the price is more affordable. However, for large FR4 sheet, its processing difficulty and transportation costs will increase significantly, resulting in higher prices. In addition, large FR4 sheet also requires more space and resources during production and storage, which also increases its cost.

Combining these factors, the price of FR4 sheet typically ranges from US$2.5-5.5/kg. This price range covers a wide range of specifications from thinner, smaller sheets to thicker, larger sheets. Of course, the specific price needs to be considered according to market demand, raw material prices and production costs.

In short, the price of FR4 sheet is affected by a variety of factors, of which the thickness and size specifications are the most significant two factors. For electronic manufacturing enterprises, in the choice of FR4 sheet needs to be based on their own needs and budget for comprehensive consideration, in order to choose the most suitable for their own products.
