A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. PCB's can be single sided (one copper layer), double sided (two copper layers) or multi-layer. Conductor on different layers are connected with plated-through holes called vias. Advanced PCB's may contain components - capacitors, resistors or active devices - embedded in the substrate.
Growing demand for PCB PCB manufacturing equipment manufacturers to meet user requirements changing new equipment. Request the board thinner, smaller hole, spacing finer, promote equipment manufacturers to improve its product performance. In the United States, equipment manufacturers in the development of better sensor technology, machines capable of small pore and micro hole, and shorten the production process of other properties. Now, laser imaging device can write 50 microns.
With the development of PCB industry, the requirement of PCB are changing, too. According to industry sources say that the future will have two typical PCB changes significantly. The first is more popular surface-mount technology. A percentage of the total market, the surface mount PCB share growing rapidly, especially for the U.S. PCB manufacturer. IPC, estimates that in 1993 64% for the PCB industry production of laminate is made of surface-mount application, while only 2% in 1984. The second is the line density increase sharply. Today is more thin laminated board, with smaller and more sophisticated drilling spacing between lines. IPC, estimates that in 1992 the United States fully 27% of PCB manufacturers use 15 mm to 25 mm spacing, compared to 14% in 1990. 1992 hole diameter of 482.6 microns or less some board accounted for about one-third of the board. Two factors that led to a new and powerful market to replace the PCB manufacturing equipment, and puts forward new requirements for PCB manufacturing equipment.
Improve the board line density of the development of technology, make the PCB industry production process and technology on the old capital equipment, equipment maker, agreed that the increase of the circuit density and smaller hole and more sophisticated line spacing of the changing of the specifications of the products required of them.
To meet the requirements of bat smaller aperture, drilling and the given specifications of the equipment manufacturers to adjust their product line, in order to develop and provide the most accurate, low cost, small and micro hole, the ability of development and provide flexible configuration of drilling workshop automation equipment.
With proprietary uv laser imaging technology, called Polyscan (used to generate large graphics). Polyscan laser imaging system by eliminating the steps contained in film production, inspection and repair to simplify the production of PCB. Using the system to avoid defects caused by membrane, and cancel the basic inspection steps in the process of imaging.
High-speed direct imaging PolyScan 2000 series products have multiple beam laser design, it provides more than 60% to the substrate surface generated by ultraviolet ray, allows the use of standard instead of special high photosensitive layer. Products can be in the typical 45.72 mm x 609.6 mm substrate tablet the same printing machine productivity and projection in 50 microns.
Will move for flat panel display technology to PCB manufacturing, push forward direct imaging, in order to produce a finer lines, creating better automation equipment, greatly improve the high-definition images of cycle.
Design, production, sales, PCB industrial use of automated manufacturing systems, including manual and automatic loading and unloading of drilling system, system of a given line, contour line machine and network products. Now provide PCB drilling system and technology to help PCB manufacturers get higher production efficiency. Strong demand for current products, annual sales growth of 44% last year.
