1. PCB bare board refers to a printed circuit board that has not had any through-holes or electronic components added. It is often referred to as a bare PCB board, and sometimes also as a PCB.
2. Bare PCB boards only consist of basic channels, patterns, metal coatings, and PCB substrates.
FR-4 is a code name for a fire-resistant material grade, representing a material specification where resin materials must self-extinguish after combustion. It is not a material name, but a material grade. Currently, there are many types of FR-4 grade materials used in general circuit boards, mostly composite materials made of functional epoxy resin with fillers and glass fibers.
In the industry, FR-4 epoxy glass cloth laminates are commonly referred to as FR-4 epoxy glass cloth, insulation board, epoxy board, epoxy resin board, brominated epoxy resin board, FR-4 fiberglass board, FR-4 reinforcement board, FPC reinforcement board, flexible circuit board reinforcement board, FR-4 epoxy resin board, flame-retardant insulation board, FR-4 laminated board, epoxy board, FR-4 optical board, FR-4 fiberglass board, epoxy glass cloth board, epoxy glass cloth laminate, and circuit board drilling pad.
FR4 is made of epoxy resin and glass fiber and is the most widely used material in PCB manufacturing due to its excellent electrical, mechanical, and thermal properties. It is suitable for high-frequency and high-performance applications.
The bare PCB board is the skeleton of traditional circuit boards which guide current through appropriate paths and is used in most electronic devices. Its simplicity provides engineers and designers with the freedom to add components as needed, and it is capable of mass production.
This type of PCB board requires more design work than other methods, but it can often be automated after assembly and manufacturing, making it the cheapest and most effective choice. Bare boards are only useful after adding components, with the ultimate goal of becoming a complete circuit board with multiple uses if matched with suitable components.
FR-4 epoxy glass cloth laminate is classified by its surface colors: yellow, white, black, blue, etc. It is the substrate used for PCBs and is a category of sheet materials, mainly classified into four types according to their different reinforcing materials.
FR-4 epoxy fiberglass cloth substrate is a type of substrate that uses epoxy resin as the adhesive and electronic-grade fiberglass cloth as the reinforcing material. Its mechanical properties, dimensional stability, impact resistance, and moisture resistance are higher than those of paper substrate. It has excellent electrical performance and a high operating temperature, making it suitable for double-sided PCBs with a large amount of usage.
The most widely used product model for epoxy fiberglass fabric substrate is FR-4 due to its high Tg and its application in electronic product installation technology and PCB technology. A bare PCB board is a template in the production of printed circuit boards, which undergo chemical corrosion and other process steps to ultimately obtain a PCB circuit board.
