PCB Test Strategies

Posted on June 04, 2019 by G

As automated test equipment becomes part of the overall electronics assembly process, DFT must include not only traditional hardware usage issues, but also knowledge of test equipment diagnostic capabilities.

The DFT team should be aware of the existing testing strategy. As OEMs turn to relying on more and more CMs, the equipment used varies from plant to plant. Without a clear understanding of the manufacturer's process, too many or too few tests may be used. Existing test methods include:

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.

Film

Posted on May 23, 2019 by G

The film consists of a protective film, an emulsion layer, a bonding film, a film base and an antihalation layer. The main components are silver salt photosensitive materials, gelatin and pigments. Under the action of light, the silver salt can be reduced to the center of the silver core, but it is not dissolved in water. Therefore, it can be suspended in a gelatin state and coated on the substrate. The emulsion also contains a pigment to sensitize. The exposed film is then obtained by actinic action.

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.
