The process of testing PCB circuit boards is a critical step in the manufacturing and assembly of electronic devices. It involves a series of meticulously designed evaluations and assessments to confirm that the PCB functions as intended and is free from defects. These tests not only assure the quality of the final product but also play a crucial role in identifying and rectifying issues early in the production process.
With the rapid development of electronic design technology and manufacturing technology, electronic products are gradually developing towards high density, high functionality, light,small, and high transmission rate; In addition, with the rapid development of chip miniaturization and the increase of the number of data transmission, the working frequency of the system is higher and higher, and…
When the PCB design is completed, the laminate layer is determined, and the PCB board has been put into fabrication, the simulation evaluation found that the high-speed signal channel margin may be unsafe. Is there still a chance to improve? Let’s first introduce the loss classification of PCB. There are three kinds of losses: conductor…
How to choose how many layers of boards are used for design and how to stack them, Today we are going to talk about this topic. The following are some common stacked structures, let’s analyze them： PCB Layer stackup of single-sided and double-sided boards For two-layer boards, there is no stacking problem due to the small…
