Panelization refers to the process of combining multiple small PCB boards into a single larger panel by the manufacturer. 1. Why Panelize? What Are the Benefits of Panelization? 1. To meet production needs. Some PCB boards are too small to meet the requirements for fixtures, so they need to be panelized for production. 2. To … Read more
1. Layout 10 Rules for Component Layout: 1. Follow the principle of “large first, small later, difficult first, easy later,” meaning important circuit units and core components should be laid out first. 2. The layout should refer to the schematic diagram, arranging major components based on the main signal flow direction of the board. 3. … Read more
There are many factors that engineers need to consider. This article organizes some detailed issues that need attention in PCB layout. Let’s check if you are aware of them! 01 Layout of Special Components Heating components should be placed in a location conducive to heat dissipation, such as the edge of the PCB, and away … Read more
1Introduction to Circuit Boards 1. Flexible Printed Circuit Board A flexible printed circuit board (Flex Print Circuit, abbreviated as “FPC”) is a printed circuit board made of flexible substrates, which can be single-sided, double-sided, or multi-layered. It features light weight, thinness, compactness, high density, high stability, and flexible structure. Besides static bending, it can also … Read more
A backplane PCB is a special type of circuit board that is typically located at the back or bottom of electronic devices, used to support and connect various electronic components and subsystems. Unlike conventional PCBs, backplane PCBs have higher layers and complexity to accommodate a large number of connectors, slots, and other connection devices. They … Read more
Source: SiP and Advanced Packaging Technology Author: Suny Li The three main characteristics of Rigid-Flex circuits are Multi-bending, Multi-stackup, and Multi-zone. In this article, we will take a detailed look at the multi-layered design of Rigid-Flex. 01 Multi-Stackup Multi-Stackup Multi-stackup refers to different numbers of layers and thicknesses in different areas of the substrate, meaning … Read more
