Aerospace circuit boards are one of the important components in the aerospace industry. This article will comprehensively analyze the three-proof standards for aerospace circuit boards, namely moisture-proof, salt spray-proof, and mildew-proof. Implementation of these standards is critical to ensuring flight safety. The reasonable design and implementation of moisture-proof, salt-spray-proof, and mildew-proof measures can greatly improve […]

PCB positive and negative films are two important steps in the PCB manufacturing process, and there are some differences between them. Below we will explore the flow of these two processes and their differences in detail. First, let’s understand the concepts of positive and negative films. In PCB manufacturing, the photolithography process mainly involves the […]

When designing a PCB (printed circuit board), one of the most basic issues to consider is how many wiring layers, ground planes and power planes are needed to achieve the functions required by the circuit. The wiring layers, ground planes and power planes of the printed circuit board The determination of the number of plane […]

PCB board edge safety distance refers to the minimum safety distance between the edge of the circuit on the PCB board and the board boundary. The determination of this distance is very important to ensure the reliability of the circuit and prevent interference between circuits. This article will discuss in detail the appropriate range of […]
