Can I cut PCB with scissors? Why do I need to cut PCBs?Cutting PCBs is an important process for customizing and optimizing electronic projects. There are several reasons for cutting PCBs.Personalizing Boards from Panel ArraysWhen you work with PCBs, you often come across PCB panelization, where multiple smaller boards are mass-produced and connected together to
Generally speaking, when designing ordinary single-sided and double-sided boards, there is no need to consider the pcb board stack up problem. Usually, copper clad boards with copper thickness and board thickness that meet the design requirements are directly selected for direct processing. However, when designing PCBs with more than 4 layers, the stacking design directly
The outlook for the global chip contract industry will remain stable by 2024. TSMC ranks first with a market share of about 60%, followed by Samsung, Taiwan’s UMC, the United States’ GlobalFoundries, China’s SMIC IC, and Huahong. The list has not changed for many years. Among them, the highest ranking in mainland China is SMIC,
Why do we need to test circuit boards? how to test a printed circuit boardTesting circuit board methods, how to test PCBs? Generally speaking, PCB manufacturers provide different PCB testing methods to customers when placing PCBs, and some of them are highlighted below:Visual inspection:This inspection is done manually by a trained operator with the help
PCB board thickness usually refers to the overall thickness of the PCB, including the circuit layer, dielectric layer, and copper cladding layer. Thick pcb board are usually expressed in millimeters (mm), and common thicknesses include 0.6mm, 1.0mm, 1.6mm, 2.0mm, 2.4mm, etc. When designing a PCB, it is necessary to select the appropriate board thickness according
what tool to cut keyboard pcb? First of all, cutting boards is a must for many reasons. One common reason is that some of the projects you are working on require board sizes that are not easy to source unless you are willing to invest more money and negotiate with the manufacturer. Therefore, you may
Lead is a chemical element with an atomic number of 82 and an atomic weight of 207.2 u. Lead is a heavy metal that is denser than most common materials. It is a soft, malleable metal with a low melting point. Freshly cut lead is a bluish silver, but it loses its luster and turns
Screw terminal pcb refers to a component similar to an inductor that is made by directly drawing a coil on the pcb board with traces. Because this process has the characteristics of good voltage resistance, good consistency, flexible wiring, and strong current carrying capacity, it is widely used in the field of antennas. So how
