Flexible PCB is carefully designed to cope with bending requirements, and their bend radius is a core parameter that ensures their functionality and durability. This parameter determines the extent to which the PCB can be bent safely without damage. The bending radius of a flexible PCB is influenced by a number of factors, the main
In 1936, Austrian Paul Eisler first utilized printed circuit boards in radios. By 1943, the technology was commonly used by Americans for military radios. And it was not until 1948 that U.S. officials officially approved the invention for commercial use. It was only from the mid-1950s that printed circuit boards came into widespread use. Before
Wafer testing is divided into two main categories: wafer testing (CP testing) and finished product testing (FT testing). Wafer testing is a moderate test of the capacitance and circuit function on each wafer after wafer fabrication is completed to ensure that its circuits are functioning properly before it is sent to the packaging plant for
Hard gold PCB is a printed circuit board with a layer of hard metal plated on its surface. This hard metal not only enhances the PCB’s abrasion and corrosion resistance, but also greatly improves its electrical conductivity, making hard gold PCB in high-frequency, high-speed, high-current electronic equipment outstanding performance. Application of Hard Gold PCBHard gold
PCB damage often results from mishandling. In the PCB assembly workspace, circuit boards can be dropped, bumped or mishandled when placed on a carrier. So, when a laminate suffers such damage, can it be repaired? The answer, as with most engineering issues, depends on the circumstances. Electronic products are categorized according to the industry standard
In the manufacturing process of electronic equipment, pcb layout is a crucial link. A reasonable circuit board layout can ensure the efficient and stable operation of electronic equipment, but also help to improve production efficiency and reduce production costs! Seven principles of device layout in circuit board designConvenienceIn the circuit board design will often be
Surface mount PCB, that is, a variety of electronic components directly mounted on the surface of the PCB, and then fixed by welding and other processes. This technology eliminates the traditional plug-in technology of piercing, pin bending and other cumbersome steps, greatly simplifying the manufacturing process and improve production efficiency. At the same time, because
Printed circuit boards are the basis of modern electronics. As such, they require special care and precision in their production and manufacturing processes.
