Comments: Before the CSP "Great Leap Forward", please clear the concept!

Since 2016, flip-chip and CSP are becoming two hot topics...

However, these two technologies are not parallel packaging technologies, but are cross-over and fused. Among them, flip-chip represents the mounting method of the chip electrode, and CSP represents the size of the package relative to the chip.

From the current industry development trend, it can be seen that flip-chip technology has a place in the middle and high power. CSP is mainly realized by flip-chip technology. Flip-chip CSP will not replace SMD and EMC package structures in the short term, but the flip-chip CSP will be big in the future. The power market will have certain advantages and scale.

Some experts in the industry pointed out that "CSP is currently widely used in the field of backlight applications, but there is still no cost performance in the lighting industry. After the packaging factory is forced into Liangshan, SMD products suddenly have a way out, SMD two years ago The price, CSP may have the advantage of substitution, but at such a low price, perhaps it does not make much sense."

It is true that from the current technical point of view, it is difficult to see that a certain technology can replace all other technologies in the field of LED packaging. Each technology trend has its own advantages and disadvantages, depending on different applications.

1, CSP troubles "revolution"! Whose life, price OR quality?

It is undeniable that CSP technology is one of the most controversial topics in the LED lighting industry, but for the new technology of CSP, many LED companies still adopt a wait-and-see attitude.

Today, the majority of high-quality companies that insist on not fighting price wars hold a wait-and-see attitude. They believe that this technology is still unstable and cannot guarantee product performance. They are more willing to follow the original production methods to ensure product quality.

In addition, compared with the CSP products of international manufacturers, the domestic price is civilian, the cost performance is higher, and it has a competitive advantage.

Industry experts pointed out that 2016 will be the outbreak of the promotion and application of CSP products, I believe that CSP will be popular in the next two or three years. Based on the various advantages of CSP, the future development prospects are worth looking forward to.

In general, no package, no heat, no power, the simpler the better! CSP is in line with this trend, the design structure is simplified.

2, the prospects of brightly flipped LED into a public enterprise layout focus!

With the gradual development of the LED lighting market, flip-chip LED products undoubtedly have a huge market space, and in the production process of these flip-chip products, the selection of flip-chip accessories is also crucial.

Among them, the application of solder paste in flip-chip devices has attracted much attention from enterprises. For LED package products, packaging materials and package structures are the main factors affecting their performance.

Insiders pointed out that in the LED packaging market, flip-chip will be a trend, but now the market share of flip-chip is indeed very low, the problem is undoubtedly the cost control.

In addition, with the deepening of high-power LEDs in semiconductor lighting applications, LED packaging technology is becoming more and more powerful and integrated.

3, LED power supply traps "closed cycle"? Intelligent into a straw?

Since entering 2016, Gaogong LED has heard a common voice in the industry during the visit to the company, which is “simplification”.

"The structure of the future lighting must be simple, the lighting area must be the smallest.", "The lamp is just a light, it must be simple to use, to meet customer needs, and linear is the simplest."

At the same time, if you can't be the first brand in the market, then create a new market segment to be the first. The market segment is the king's law, which has been successfully demonstrated by many companies.

Although the LED driver power supply has become smarter and has not yet matured, it has formed a true standardization. However, with the gradual reduction of prices, LED smart power products will gradually move toward the mass market and tend to be civilian.
