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.

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.

Overview of High Precision Technology for PCBs

Posted on May 06, 2019 by G

The high precision of printed circuits refers to the use of fine line width/pitch, micro holes, narrow ring width (or no ring width), and buried, blind holes and other technologies to achieve high density. The high precision means that the result of "fine, small, narrow, thin" will inevitably bring high precision. Take the line width as an example: O.20mm line width, and O.16-0.24mm is qualified according to the regulations. The error is (O.20 soil 0.04) mm; and the line width of O.10mm, the same error is (0.10±O.02) mm, obviously the accuracy of the latter is doubled, and so on is not difficult to understand. Therefore, the high precision requirements are not discussed separately. But it is a prominent problem in production technology.

Introduction to HDI and circuit boards

Posted on April 28, 2019 by G

Since the printed circuit board is not a general end product, the definition of the name is slightly confusing. For example, the motherboard for the personal computer is called the motherboard and cannot be directly called the circuit board. Although there is a circuit board in the motherboard, It's not the same, so when you evaluate the industry, you can't say the same thing. For example, because there are integrated circuit parts on the board, the news media called him an IC board, but in fact he is not equivalent to a printed circuit board.
