Composition and technology of placement

Placement machine is a high technical content in electronic assembly equipment equipment, mechanics, optics, electronics, materials, mechanics, automation and disciplines, such as computers, materials processing, mechanical transmission, motor and servo drive, pneumatic, laser, visual image, sensor, automatic control and computer hardware/software and other series of integrated technology, is one of the main symbol of the levels of electronic manufacturing equipment development.Since its inception, the placement machine has been constantly updated in technology, enhanced in function, improved in performance index, improved in automation and intelligence, and adapted to the development trend of micro-miniaturization, multi-function and low cost of electronic information products.

With the diversification and personalized trend of electronic products, electronic components are becoming smaller and smaller, with more and more pins, thinner and thinner spacing, and more and more compact mounting positions.Placement machine of high precision, high speed and flexibility in the continuous development.Although various and various placement machines are dazzling, the basic functions and working principles of placement machines have not changed fundamentally, and the basic composition and technical principles of various placement machines are the same.

With the development of the electronic industry, electronic components become more and more sophisticated and diversified. At present, chip components have been developed from 0402 (1005 in metric system) to 0201 (0603 in metric system) and 01005 (0402 in metric system).In addition, a large number of packaged components such as BGA,CSP/BGA,FC and MCM emerge and are widely used, which objectively puts forward higher requirements for the placement equipment and higher requirements for assembly efficiency.Placement machine is the key equipment of integrated circuit board (PCB) assembly line. It can attach the components (such as patch capacitor, patch resistor and patch chip, etc.) to the designated position of the integrated circuit board with high speed and high precision, and conduct quality inspection and identification of the components before the patch.Placement machine is a highly automatic equipment integrating precision machinery, automatic control and computer systems, mainly composed of rack and drive system, computer and hardware control system, servo and drive system, software system and feeding system.

The placement machine is actually a kind of precise industrial robot, which is a combination of electro-optical and computer control technology.
