Since entering this year, the door to the CSP market is being opened. In foreign countries, such as Japan and South Korea CSP has a higher market penetration in the TV backlight and flash market. In the lighting market, some big brand manufacturers have also begun to design and promote.

In 2016, the last month will be entered. In the past one year, there have been many positive changes in CSP, mainly reflected in the substantial improvement of product performance, standardization formation, and improvement of supporting industrial chain.

According to Zheng Haibin, deputy general manager of Zhaochi Energy-saving Lighting Co., Ltd., “These changes indicate that the CSP market is slowly maturing, and the main factor driving these changes is that the prospects of CSP products are being favored by more and more people; meanwhile, CSP products The high light efficiency and low thermal resistance performance are being recognized by more and more people and have irreplaceable advantages in specific fields."

It is understood that in August this year, Zhaochi Energy-saving Lighting Co., Ltd. successfully developed new products CSP1313 and CSP1010, and successfully launched it to the market. It is worth mentioning that, based on the innovative and strong market competitiveness of CSP1313 and CSP1010 series products, Zhaochi Energy-saving Lighting decided to bring this product to compete for the 2016 Innovation Golden Product Award “Innovative Product of the Year”.

At present, the CSP1313 and 1010 products of Zhaochi Energy-saving Lighting are based on flip-chip and the company's own patch application technology and end-user resources, completing the overall technical path from packaging to placement to application, providing the client with In addition to the more reliable CSP products, it also provides product placement technology support to help the application side to better reduce the cost of its luminaire solution system.

According to Zheng Haibin, “The production line of CSP products of Zhaochi Energy-saving Lighting adopts high-precision and high-automatic production equipment to ensure the production quality and production efficiency of the products. At the same time, the company's special fluorescent coating process adds a better color of CSP products. Uniformity makes the BIN more concentrated (lighting MAC Adam 3 steps BIN up to 99%)."

It is understood that Zhaochi Energy-saving Lighting has carried out technological innovation and improvement in the process of developing CSP1313 and CSP1010 products. Mainly reflected in the following six aspects.

1. The leadless frame package saves the LED product cost by more than 30%, and completely avoids a series of performance problems such as vulcanization and poor airtightness caused by the failure of the lead frame;

2. The production efficiency is improved. The implementation of the project simplifies the production process, directly bans the least efficient welding line process in the traditional production process, improves the production efficiency by 100%, and reduces the production cycle by 50%.

3. The non-bonding wire package adopts flip chip and removes the bonding wire to realize the thinning of the product, and completely eliminate the LED product failure caused by the short wire of the bonding wire, and greatly improve the reliability of the product;

4, ultra-small package, simplified packaging around the LED chip to achieve miniaturization of LED products (product area and chip area ratio <1.2 times), greatly increasing the design space of the finished product, allowing the dimming scheme of the subsequent lighting module Infinite possibilities arise;

5, silica gel modification technology, through the filling and reinforcement modification treatment of silica gel, directly solve the heat-resistance bottleneck of CSP technology material, realize the material constraint breakthrough of CSP product performance, and ensure the full performance of flip-chip performance on CSP Play

6. Angle selection, multi-angle control of CSP light source can be realized by controlling the CSP light-emitting surface, which can provide customers with more choice of light-emitting angle.

Although the CSP1313 and CSP1010 products have been introduced to the market for a short time, they have been highly praised by many customers.

Some customer reviews:

1. The product has small size, small volume, low thermal resistance and good reliability. It has obvious advantages in the application of large wattage and high optical density floodlights.

2. This CSP is flexible and convenient in dimmable, color-adjustable COB and integrated module applications.

3, replace the existing ceramic packaging products, low cost, low thermal resistance, good reliability, a very competitive product.

4. The product has small thermal resistance and small size, and has relatively strong competitiveness in the application of the dual color temperature module.
