The circuit board is the backbone of almost all electronics. But it has long been more than just a conductor track carrier. It is an electronic component that can do more than just connect chips. Here we will explain the basics and types of printed circuit boards (PCBs) and make it as easy as possible for you to understand them. To understand the types of PCBs, you first need to understand their structure. PCBs include prepregs and cores. Board core material and copper foil molding between the layers of insulation. Laminate is a material used as the basis for the manufacture of circuit boards, also known as copper clad. Laminates are made of glass cloth impregnated with resin woven with highly insulating glass fibers. Classification by their parts and structure The types of PCBs are classified based on the parts and structures used. The six main types are as follows. Rigid boards This type of board usually has a hard copper or epoxy composition. This results in high strength and easy mounting of electronic components. Photoelectric Rigid PCB Flexible boards Rigid and high-strength printed circuit boards are called rigid boards, while printed circuit boards using flexible plastic films are called " flexible boards". Since this type of printed circuit board can be bent, it is often used for moving parts in electronic devices. Rigid-Flexible Boards A printed circuit board that combines a rigid board and a flexible board is called a "rigid-flexible board". This type of board combines the advantages of high flexibility and strength. This makes it easy to mount electronic components, but it also has the disadvantage of being slightly larger in size. Layered Rigid-Flex PCB Single-sided A rigid board in which printed or electronic components are mounted on one side only is called a "single-sided board". This type of printed circuit board is not suitable for forming complex electronic circuits. It has significant advantages in terms of cost reduction. Double-sided A "double-sided" board is a board on which both sides are printed and on which electronic components are mounted. This type of board is more suitable for forming complex electronic circuits than single-sided boards. It has the disadvantage of higher cost. The above is a general classification of PCB types. You may have heard of high-frequency PCBs, multilayer PCBs, flexible PCBs, and some other advanced types not listed above. However, you can refer to TOPFAST, which manufactures, designs and provides one-stop customization services for various high-end PCBs. Assembled boards Printed circuit boards with multiple layers are called "laminates". These types of PCBs were used in the 80s mainly as components for high-performance computers. Telecommunication PCBA Classification by substrate The types of PCB boards can be broadly classified into: paper phenol and glass epoxy. Paper phenolic boards are made by hardening the paper substrate with phenolic resin containing grease. Although it is inferior to glass and epoxy resin in terms of electrical characteristics and heat resistance. It is widely used for consumer use because of its low price, of which the production volume is the largest including overseas. Glass epoxy resin substrates are used for circuits that require strength and insulation. There are various other materials for printed circuit boards. There are composite substrates that mix paper and glass substrates, and flexible substrates that can be bent using plastic film as the substrate. If you are looking for excellent flexible boards, you can choose TOPFAST, which has more than 20 years of experience in high-end PCB manufacturing. the global demand for printed circuit boards is expanding. Printed circuit boards can be classified into various types according to their characteristics and processing methods. At the same time, these characteristics will be further utilized in the future to develop small, high-performance electronic devices worldwide.

We first need to understand what PCB thickness is . PCB thickness is the thickness of the finished circuit board. the nominal thickness of copper-clad boards is 0.5, 0.7, 0.8, 1.0, 1.2, 1.5, 1.6, 2.0, 2.4, 3.2, 6.4 mm. the nominal thickness of paper-based copper-clad boards is 0.7 to 1.5 mm Standard Copper Thickness When we talk about the thickness of copper when implementing a printed circuit, we are referring to the thickness of the tracks and pads, whether they are inside or outside of the layer. PCB copper thicknesses are generally classified as 1oz (35µm), 2oz (70µm), and 3oz (105µm). Of course, the copper thickness depends on what kind of board you make. The greater the weight of copper, the better the electrical properties of the board. But the more difficult it becomes to etch the board. For mass production of boards, please make sure that the minimum pattern width/pattern pitch meets the specifications. We offer a complete customization service for you, please contact us to learn more. PCB Core Thickness The substrate, also known as the dielectric, is the insulating material that separates the two conductor layers. The core is a copper-clad material that hardly changes its thickness during the manufacturing process of the board. In a two-layer printed circuit, there is therefore a central substrate between the two copper layers, often referred to as the top and bottom. The standard thickness of the substrate is 1.6 mm for two-layer circuits and 4/6-layer multilayer circuits. However, due to the minimum thickness of the layers, usually the more layers, the thicker the printed circuit board. Thicker or smaller thicknesses may be required for mechanical reasons or for characteristic impedance. aircraft circuit boards professional PCB design team Prepreg thickness In the laminate structure of a printed circuit board, there are always 2 to 3 pieces of prepreg between the 2 copper cores. They are pressed together with the core. Unlike the cores, the prepreg changes its effective thickness during the pressing process. Therefore, the thickness depends on the PCB manufacturer, its process setup and the ratio of copper cladding area to open space. Inner PCB thickness In addition to the layer order, the true customization of the stack includes the definition of the internal PCB thickness. In particular, the vertical distance between the floor where the copper rails are placed. It is important to clarify immediately that the internal thickness values do not have complete freedom. Because in fact, these thicknesses are the result of a specific construction order of the printed circuit. In a sense, to obtain a certain thickness configuration, it is necessary to build with a certain structure. Consumer Electronics PCBA Standard PCB thicknesses Printed circuit boards have standards such as JIS, JPCA, IPC/JPCA, UL, etc. Materials and PCB thickness vary by standard. PCB thickness is not only the thickness of the board itself, but also the thickness of the copper foil section, the thickness of the plating section, etc., which varies depending on the material of the printed circuit board. The standard thickness of 2-layer PCB thickness is 1.6mm. our expectation is that the PCB fab has some copper clad core and the total thickness of copper and FR4 material is equal to 1.6mm. If you want to control the copper thickness of the PCB, you just write your requirements clearly, tell us, and the manufacturer will make the copper thickness according to your requirements.
