PCB Circuit Board Testing, Inspection and Specification (2)

Posted on March 26, 2025 by G

This article provides an in-depth exploration of key terms and techniques in PCB circuit board testing and inspection, covering everything from basic quality control methods to advanced testing technologies. It begins by explaining acceptability and acceptance standards, followed by the application of Acceptable Quality Level (AQL). The article then discusses common defects in PCB manufacturing, such as air inclusion bubbles, blistering, and copper foil warping, and highlights how Automatic Optical Inspection (AOI) and Automatic Testing Equipment (ATE) ensure PCB quality and reliability. Additionally, various quality tests, such as cross-cut tests, continuity tests, and solderability tests, are covered, offering strategies for ensuring that PCBs meet industry standards. By exploring these testing methods and techniques, the article helps PCB manufacturers and quality control professionals improve production efficiency and maintain high product quality.

Why do PCBs have to be multi-layered

Posted on June 13, 2019 by G

For the most basic PCB, the components are concentrated on one side, and the wires are concentrated on the other side. Because only one side can be wired, we call this PCB a single panel. Both sides of the double panel can be routed, so the wiring area is twice as large as that of a single panel, making it suitable for use on more complex circuits.

PCB Design Preparation

Posted on May 31, 2019 by G

Design requirements: The designer must read the schematic diagram in detail, fully communicate with the project engineer, understand the circuit architecture, understand the working principle of the circuit, and clearly understand the layout and routing requirements of key signals.

Overview of PCB Via

Posted on May 27, 2019 by G

Via is one of the important components of a multi-layer PCB. The cost of drilling is usually 30% to 40% of the cost of PCB board. Simply put, each hole in the PCB can be called a via.

Computer Aided Manufacturing (CAM)

Posted on May 20, 2019 by G

Computer-aided manufacturing technology, the English name is Computer Aided Manufacturing, referred to as CAM, is an advanced technology that is controlled by computer control. The development of computer technology and the emergence of laser plotters have led to the use of PCB-assisted manufacturing technology. Various CAM systems can generally process the gerber data (Gerber data), eliminate various defects in the design, make the design easier to produce, and greatly improve the production quality.

PCB Engineering

Posted on May 20, 2019 by G

For the production of PCB printed boards, because many designers do not understand the production process of the circuit board, the circuit diagram of the design is only the most basic circuit diagram, and can not be directly used for production. Therefore, it is necessary to modify and edit the line file before actual production. It is not only necessary to produce a film map that can be suitable for the production process of the factory, but also to make corresponding punching data, mold opening data, and other data useful for production. It is directly related to various production projects in the future. These require engineers and technicians to understand the necessary production processes, and at the same time master the relevant software production, including common circuit design software such as: Protel, Pads2000, Autocad, etc., should be familiar with the necessary CAM software such as: View2001, CAM350; GCCAM Etc., CAM should include PCB design inputs, which can edit, correct, repair, and imprint circuit graphics, use disk as the dielectric material, and output automated data for ray mapping, drilling, and inspection.
