Chip diodes, semiconductor discrete devices, integrated circuits, optoelectronic devices and other electronic devices, electrical business scope: manufacturing of electronic components, semiconductor chips and special materials. (for projects subject to approval according to law, business activities can be carried out only after approval by relevant departments)
（2） The issuer’s main business, core technology and R & D level
1. Main business of the issuer
The company is a high-tech enterprise focusing on the R & D, production and sales of semiconductor discrete devices
Various small signal devices (small signal diode, small signal triode), power devices (power diode, power transistor)
Rate triode, bridge rectifier) and other semiconductor discrete device products. The company is based on packaging and testing expertise
At present, it preliminarily has the integrated operation ability under IDM mode, and can provide customers with strong applicability
High reliability series products and technical solutions to meet customers’ one-stop procurement needs. The company has a wide range of products
It is used in computer and peripheral equipment, household appliances, adapters and power supplies, network communication, automotive electronics, industry and commerce
Industry control and other fields.
2. Core technology and R & D level of the issuer
(1) Core technologies mastered by the company
The manufacturing process of discrete devices is highly standardized, and the technology is generally combined with specific process links
If the specific problem of a process node is solved, the technology can be widely used in multiple series using this process
Products.
The company has mastered the general technology of discrete device packaging and testing, which is the mainstream in the industry
The test process was optimized to achieve accurate control, and gradually mastered the characteristics of some kinds of chips of power diodes
Design and manufacturing technology, as follows:
The process uses this nuclear correspondence
Link core technology description and characteristics main invention patent of core technology
Want products
The multi arrangement of frame design increases the number of products in each frame and improves the single small signal diode
The number of products in the high-density array bit area can improve production efficiency and reduce material consumption. Tube and optocoupler (1) ultra thin packaging frame design technology taking SOT-23 as an example, the number of products per square centimeter is increased from 4.75 to 5.71, and the density is increased by 20%. Diode, bridge technology; (2) Large current rectifier / high voltage diode
Solder paste or solder chip is pre welded on both sides of the chip, and a process is added to improve the preparation method; The chip pre welding technology has obvious effects in improving the efficiency of the welding process and reducing chip contamination. A semi conducting air hole of the welding bridge rectifier (3) is reduced from 5% to less than 3%. Welding of bulk chip
Insulating film mounting technology is an important supporting technology of multi chip stack packaging, which can meet the same or small signal diode method; (4) Due to different chip stacking requirements of core technology, the connection between the bottom of the chip and the base island will not be coated with tin overflow glue on the back of the segment, and achieve accurate chip loading effect. Paste loading formula
On the basis of general technology, through the special control of welding wire process parameters, small signal diode method; (5) The invention relates to an improvement of ultra-low radian welding wire and welding wire method, so that the separation technology of small signal device packaging welding wire arc height tube and small signal semiconductor rectifier bridge can be controlled below 40um at least, so as to realize the ultra-thin product and the preparation method of triode; For device assembly, such as dfn0603, the thickness is less than 0.25 mm. (6) The dispensing amount of axial diode packaging technology CPK performs statistical process control by automatically detecting the dispensing amount of each product, and the automatic measurement and control of power diode and protective adhesive layer test, so as to improve the control degree of the chip and ensure that the dispensing amount of each point is within the scope of polyimide Technology of controlled tube and bridge. Axial diode of current transformer
Power chip tin painting is a preparation method through the uniform walking of a special dispensing needle within the dispensing range; The welding technology makes the glue amount more uniform and the position more controllable, so as to achieve the purpose of uniform solder and reducing the hexagonal hole of the welding gas power diode (7), which can improve the performance and reliability of the power device. Chip filter
Adjust the light transmittance of silica gel, control the dispensing height and screen the formula through the proportion of silica gel color paste
The optocoupler CTR control and control chip are precisely adjusted according to the angle, and the control technology is implemented
