The COB market is on the eve of the outbreak, and Simaida's new centrifugal sedimentation machine is already on the “air outlet”.

COB has been in the market for several years. In the past two years, COB market demand is growing rapidly, especially in the high-end commercial lighting field, and the penetration rate is getting higher and higher. In addition, in the outdoor lighting market, the COB application ratio has gradually increased, so more and more manufacturers are involved in the COB market. At present, domestic packaging manufacturers including Hongli Zhihui, Zhaochi Energy Saving, Guoxing Optoelectronics, Liyang, Xuyu Optoelectronics, and Zhonghao Optoelectronics have already been closely arranged.

For the rapid growth of the COB market, Shen Cuikui, general manager of Shenzhen Simaida Electronics Co., Ltd. (hereinafter referred to as “Simaida”) said that COB products are the best choice for high-end commercial products because of their high light quality and high optical density. The COB market, like the early patch beads, is on the eve of the explosion.

It is worth noting that although COB is more competitive in terms of light quality and optical density, COB is not the mainstream of the market compared to SMD products, which also leads to the current market capacity of COB light sources is not particularly large. Since the existing COB integrated packaging technology in China is so hot, but it does not quickly occupy the market, there must be another "hidden feeling" behind it.

In this regard, Shen Cuikui pointed out its root cause: "The reason why COB has not yet broken out is that the unit price of the product is too high, and there is no way to form a positive competition with the 2835 product." At present, COB has not replaced the main part of the patch lamp. The problem is that there are too many product models and the price is not competitive. Among them, too many product models will make lighting companies become difficult to purchase COB devices, and therefore cannot be purchased and produced in batches, which inevitably increases the procurement cost of the manufacturers and the subsequent assembly costs. If the COB can have several standard devices like the 2835, it can solve these problems greatly, and thus can break the market share.

However, with the current 1313 and 1919 series COB products slowly becoming the main models of COB products, and the flip-chip packaging technology is becoming more and more mature, COB products will have a large room for decline in raw material procurement cost and production cost after the start of COB products. . In any case, when the cost and performance reach a balance point, the COB market will have a rapid growth. "I am very optimistic about the development of COB in the last 2-3 years. Compared with the patch white light, the COB will grow much faster." Shen Cuiui said frankly.

In fact, for the COB market, many people in the industry are optimistic, and more and more companies are pouring in. However, domestic manufacturers want to compete with international manufacturers such as Nichia and Langmings, not only need to consider product price issues, but also need to do a good job in product performance. In other words, it is necessary to reduce the cost by using mass production to increase the light quality and aging resistance of the product, thereby winning the market.

In short, on the basis of guaranteeing performance, how to solve the problem of excessive price of COB products has become one of the key factors for market development. As a well-known LED packaging equipment manufacturer in China, Simaida recently introduced the COC centrifugal sedimentation machine CMC-20 for the consideration of customer efficiency.

According to Shen Cuikui, as early as 2016, there were customers who entrusted Simaida to develop COB centrifugal sedimentation machine. Due to the technical difficulties at the time, many problems were difficult to solve. It was decided to attack this project in early 2017; May 2017 The first prototype was successfully trial-produced, but there was no way to use it. After the continuous improvement, the second prototype was launched in October of the same year, and after nearly two months of improvement, it barely met the customer requirements; Tests, after several months of testing, and a number of improvements, finally made a third generation product.

High-tech LEDs have learned that the third-generation COB centrifugal sedimentation machine can place 6-8 cartridges at a time, realizing automatic loading and unloading and automatic centrifugation. This equipment can centrifuge 1-20 pieces of material at a time, can completely centrifuge the phosphor produced by COB with the luminous surface within 19mm to the bottom of COB, and the phosphor is evenly dispersed without overflow phenomenon, the effect is controllable and the efficiency is high. Fundamentally meet the needs of the centrifugal precipitation of COB customers.

Of course, for any technology company, especially high-precision equipment companies, improving product performance, improving equipment production efficiency, and reducing customer production costs are the fundamental purposes, and related patents are needed to protect themselves and customers. Simaida's research and development COB centrifugal sedimentation machine is also based on the needs of customers and the market, and has built a strict intellectual property protection system for this product.

“Our COB centrifugal sedimentation machine is completely independent research and development, and has applied for a number of practical patents and invention patents. Customers can choose to use it with confidence, and there will be no patent troubles.”

The COB centrifugal sedimentation machine is different from the SMD patch centrifuge. The centrifuge diameter of the COB centrifuge is more than one meter. During the centrifugation, it is necessary to consider the automatic loading and unloading of the bracket, how to not overflow the glue, the influence of the airflow on the material, and the centrifugal diameter of the phosphor. The solution to the problem of uniformity of precipitation, etc., and the price and capacity, can be said to be quite technical challenges. However, Smida has successfully solved these problems.

At present, Simaida already has a mature series of centrifuge equipment. Among them, in the CMC-20 COB centrifuge, Smida is the first manufacturer to develop physical centrifuges for COB. Now customers have already placed orders and built laboratories, which already have the ability to mass production; Cartridge centrifuge CM-3000, this product can solve the demand of large-volume centrifugation of patch products. The capacity of one cartridge centrifuge is similar to that of 8-10 automatic small centrifuges, which greatly reduces the customer's site. Cost and labor cost; CMA-20 automatic centrifuge, designed for EMC products and special bracket backlight products, can meet the centrifugal requirements of 200mm and above 280mm length, 60mm and 75mm width LED patch products, so that customers do not need Buying more equipment can balance the centrifugation requirements of most brackets; CMA-25 automatic centrifuge can centrifuge 1-25 pieces of material at the same time, customers can choose different procedures according to the specifications of their own production line, you can achieve efficiency the goal of.

Shen Cuikui introduced that the CMA-20 and CMA-25 centrifuges are the first in the market to adopt mechanical positioning (patent applied), accurate positioning, no jamming. The bottom plate in contact with the bracket is specially designed to be centrifuged in a case where a part of the product has a large amount of glue, and the glue does not stick to the pad of the lamp bead after overflowing, thereby reducing the defective rate and reducing the labor cost of cleaning the device and Standby cost.

In the future, as the power of single lamp packaged in white light is getting higher and higher and the weather resistance is getting higher and higher, the demand for centrifugation will be more and more. For the market segment demand, Simaida will continue to introduce some Competitive products to meet customer needs, but also to enhance their market share, to provide customers with better services and more competitive products to return customers' love.
