Ordinary PCB is usually made of copper foil and substrate, and the substrate material is mostly fiberglass (FR-4), phenolic resin (FR-3), and other materials. The adhesive is usually phenolic, epoxy, etc. During the PCB processing process, due to thermal stress, chemical factors, improper production processes, etc., or due to the asymmetry of copper paving on …
The currently available PCB cleaning processes include water-based cleaning, semi-aqueous cleaning, solvent cleaning, and no-clean process. We have discussed the first 3, today we will introduce no-clean process. What is a No-clean Process? The no-clean process refers to the quality and process control of raw materials such as printed circuit boards and electronic components. The alternative …
Soldering is an important step in the production of electronic equipment. After soldering, there are always varying degrees of flux residues and other types of contaminants on the circuit board surface, even if a low-solid content, halogen-free, no-clean flux is used. There will still be more or less residue. In order to prevent circuit failure …

The standard thickness of a printed circuit board (PCB) can vary based on the specific application, type of PCB, and the industry standards followed. However, some common standard thicknesses exist. Here are a few examples: Standard Thickness for Single-Sided PCBs: 1.6 mm (0.063 inches) is a commonly used standard thickness for single-sided PCBs. Standard Thickness …
Flexible Circuit boards are generally customized products with widely varying shapes and performances. They can be divided into the following types according to the number of layers. 1. Single-sided Flexible Board Lowest cost. When the electrical performance requirements are not high and single-sided wiring is possible, a single-sided flexible board should be selected. This most …
A PCB copper plane is a layer in a PCB with copper on it after etching, usually traces and pads or power and ground planes. PCB copper material Copper foilCopper foil is the cathode portion of the electrolytic material, which is deposited on a continuous thin metal foil layer on the PCB substrate. You can …
A printed Circuit Board (PCB for short), also known as the circuit board, PCB board, aluminum substrate, high-frequency board, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc., is an important Electronic components are supports for electronic components and providers of circuit connections for electronic components. Traditional circuit boards use the method …
