What is the printed connection plate?
Printed connection plate is a frame used for many modern electronic components. These boards are usually green colors with several styles of electrical components and connected computer chips. The printed connection plate has an extremely high reliability associated with very low costs. As a result, these boards are common in everything from mobile phones, toys for children to cars.
All printed cable boards are made of a non -conductive material called a substrate. This material is the base of the board. It must be light, strong and completely non -conductive. Most boards are made of a combination of materials created by man, such as polyester or glass fiber, mixed with different plastics.
The next step in creating a printed connection plate is to lay conductive tracks. For this purpose, most companies cover the entire surface of the copper alloy. After the plate is covered, any undesirable material is removed. Other manufacturers have laid the district directly on the board,But this process is more complex and costly, so it is rarely used.
To remove undesirable copper, one of the three techniques is usually used. The milling of the board works like most industrial milling, a specialized machine gets rid of undesirable substances up to extremely accurate specifications. When etching the screen, the copper that remains behind is protected, whether physically or with specialized inks, and the rest of the copper is etched. Foengraviring is the third method and is similar to the labeling of the screen. Materials and protective substances have different properties, but the process is the same.
At this point, the holes are drilled into the substrate of the printed board. Some of these openings are used as anchor points for the assembly of a plate or electric components. Other holes have inserted rivets; These rings allow electrical signals to move the side side of the board to the other. After the holes are drilled, it is deSKA covered with various sealants and protective substances.
The last step in assembling these boards is to connect electrical components. Some components are put on holes and secured on the underside of the plate. Others are placed on non -conductive pillows and work on one side. Machines usually cause mass production of printed cable boards. In smaller dose tasks or dealing with extremely small components, it is not unusual for the printed connection plate to be made manually.
After assembling the board is subjected to an automated test. The test machines flood the board by electricity and verify that all connected devices are powered as it should be. This process will also emphasize any potential shortcuts or broken paths.
