Product Description

Circuit board milling processing is to divide the PCB into the production size required by the customer, and it is also the main process that affects the customer's production and assembly. There are mainly: cutting direction, milling board compensation, positioning method.
1, the direction of the knife:
When a milling cutter cuts into a plate, one of the cut surfaces always faces the cutting edge of the milling cutter, and the other side always faces the cutting edge of the milling cutter. The former has a smooth surface and high dimensional accuracy. The spindle always rotates clockwise. Therefore, whether it is a CNC milling machine with a fixed spindle motion or a fixed spindle motion, when milling the outer contour of a PCB, the tool must be moved counterclockwise, which is commonly known as up milling. And when milling the frame or slot inside the PCB, the down milling method is used.
2. Milling plate compensation:
Milling plate compensation is when the machine tool is set according to the set value, the milling cutter is automatically offset from the center of the milling line by half of the set milling cutter diameter, that is, the radius distance, so that the milling shape and program settings be consistent. At the same time, if the machine tool has a compensation function, it is necessary to pay attention to the direction of compensation and the command of the program. If the compensation command is used incorrectly, the shape of the circuit board will be more or less the length and width equivalent to the diameter of the milling cutter.
3, the positioning method:
Positioning methods can be divided into two types: one is internal positioning, and the other is external positioning. Positioning is also very important for engineering and technical personnel. Generally, the positioning plan should be determined during the early stage of PCB production.

_____________________________________________________________________________________________

Printed circuit boards abbreviation as PCB. A conductive pattern which is formed on a dielectric material in a predetermined design to form a printed circuit, a printed component, or a combination of the two is generally referred to as a printed circuit. And a conductive pattern that provides electrical connection between components on an insulating substrate, called printed circuits.

PCB characteristics
● High density. For decades, the high density of printed boards has grown with the increased integration of integrated circuits and advances in mounting technology.
● High reliability. Through a series of inspections, tests and aging tests, the PCB can be reliably operated for a long period of time (usually 20 years).
● Designability. For the various performances of PCB (electrical, physical, chemical, mechanical, etc.), the design of printed boards can be realized through design standardization and standardization, with short time and high efficiency.
● Productivity. With modern management, it can carry out standardization, scale (quantity), automation and other production to ensure product quality consistency.
● Testability. Established relatively complete test methods, test standards, various test equipment and instruments to detect and identify PCB product qualification and service life.

● Assemblyability. PCB products not only facilitate the standardized assembly of various components, but also can be automated, large-scale mass production. At the same time, the PCB and various component assembly components can be assembled to form larger components and systems up to the complete machine.

● Maintainability. Since PCB products and various component assembly components are produced in a standardized design and scale, these components are also standardized. Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly, and the system can be quickly restored. Of course, you can say more about it. Such as miniaturization and weight reduction of the system, high-speed signal transmission, etc.
