“Localization of key equipment is a benchmark for measuring the technical level of an industry.†Henry, general manager of Shenzhen Dazu Photoelectric Equipment Co., Ltd. (hereinafter referred to as “Daguang Optoelectronicsâ€) introduced. The development of LED not only depends on the light efficiency of the packaged device, but also the light attenuation of the whole lamp. The supporting equipment and the process and technology level it represents are also an important basis for measuring the development level of the LED industry.
China's LED equipment industry started nearly 30 years later than the international. In recent years, some achievements have been made from packaging equipment to chips to epitaxial MOCVD.
Henry said that LED packaging equipment can be roughly divided into two types: automation module and optical module. Although the domestic start is late, the industry has insufficient experience and technical innovation, but it has made rapid progress in the speed and precision of equipment. “China is closer to the raw materials and end customers of the products and has many advantages in terms of human resources reserves. These will help domestic packaging equipment manufacturers to walk faster than the international market in terms of technological progress and cost optimization.â€
With the continuous advancement of technology, LED domestic packaging equipment will be more and more accepted by the market in the future.
Domestic equipment is still waiting
Equipment is the most important factor in measuring a country and an industry. The state has increased its support for high-end equipment through a series of policies. In recent years, some LED equipment companies have also grown rapidly.
It is understood that packaging products other than LED products have strict patent restrictions. Equipment patents are often limited to the peripheral mechanical and hardware functional modules, and can not be refined to specific hardware and software and process solutions, because once the application is equivalent to making their own technology public, this is a lot of manufacturers are not willing Seen, so it also gave domestic manufacturers a good opportunity to "fast track overtaking" by introducing talents or technology.
According to Henry, Dazu Optoelectronics has developed a complete set of automated packaging equipment including high-speed SMD splitter, SMDLED tape-cutting machine, high-speed planar solid crystal machine, high-speed automatic SMD gold wire bonding machine, including high-speed automatic SMD gold wire. The wire bonding machine is the most complicated and technically difficult. It is understood that the Hans5200 automatic SMD wire bonding machine of Dazu Optoelectronics is close to the international level while ensuring the welding precision and the mass production reliability. In addition, the high-speed automatic in-line wire bonding machine (HANS5110) independently developed by Dazu Optoelectronics has surpassed the latest international models.
The working principle of the wire bonding machine is thermal ultrasonic welding, in which the requirements of temperature control, ultrasonic drive control, mechanical control, multi-axis coordinated motion control, welding effect detection, etc. are very high, and it is required to have good between subsystems. Cooperate, this is also lacking in the domestic packaging equipment company. According to Henry, the wire bonding machines independently developed by Dazu Optoelectronics all adopt modular design. Especially in terms of automation, Dazu Optoelectronics fully absorbs the experience and advantages of the parent company Dazu Laser in automated laser equipment, and actively introduces foreign high-end talents. Fully mastered the international technology of wire bonding machines.
“Although the key parameters of domestic equipment have reached international standards, the overall performance still has a certain gap with the international market.†Henry said that foreign packaging equipment manufacturers such as ASM and K&S have more than 40 years of product experience and various equipment operations. The problems they have encountered and provided solutions, and domestic manufacturers because of the late start, more is "takenism", so many cases are aware that they do not know why, can not achieve excellence, this is also the domestic LED package There is little innovation in the equipment industry, and the key to the market is difficult to accept on a large scale.
"The popularity of domestic packaging equipment still has a hard way to go." Henry said that from the current sales situation of Dazu Optoelectronics, more and more manufacturers began to accept high-quality domestic packaging equipment, give up imports, switch to domestic equipment.
It is understood that it is difficult for domestic packaging manufacturers to reverse the brand effect accumulated by foreign equipment manufacturers in a short period of time. In addition, the introduction time of domestic equipment is short, and it will take time for the market to accept a large area.
