LED package: the general trend of or will go?

[LED] China Vtion change everywhere, so is the packaging industry, once the ferocious "free package" or "free package" concept was caused by panic, and even that "free package" will dominate the political arena yijianfenghou.

Why is the LED packaging technology has attracted much attention, and even some of the traditional packaging enterprises are worried about life? It is mainly used in what areas? What will be the size of the market in the future?

The first to popularize a concept, the so-called "free package" or "free package" is actually positive solution for chip scale package, namely the use of flip chip packaging directly to the pad at the bottom of the package, no gold, no stent, simplify the production process, reduce production cost, the package size can be made smaller, and package the same size can provide more power.

As the originator of the chip scale package, EPISTAR and perhaps more reliable interpretation. EPISTAR associate Linyida bluntly, "chip scale package is not encapsulated, now it seems there is no way to do free package, it is not possible to leather off the traditional package of life, and from the development of the LED industry so far, not a completely replace another packaging technology packaging technology. "

CREE (CREE) marketing director Chinese market lintie view, chip level packaging has been declared "cost advantage" does not have much convincing, but is simple at the expense of the original maturity of technology, to advance into the package process process chip made in increasing the chip made difficult, does not have the yield for the production, the original production equipment became not applicable, increase the purchase cost of new equipment, at the same time to explore new technology, then the production line workers for higher technical requirements, increase the cost of training. On the current finished product, chip packaging and no obvious performance advantage.

Why do chip level packaging, the final foothold is $1 or $1 to buy how many lumens. I think the chip package to flip chip technology to upgrade a step, become smaller and cheaper. Flip chip this year, more civilians, more convenient to use, and SMD packaging closer. "Elec-Tech LED chip division vice president Mo Qingwei's view was that optimistic. Chip level packaging can achieve a very large angle of light, in the laboratory example, the fluorescent lamp with a chip level package to replace, you can avoid the ordinary light emitting angle is narrow and lead to the black area. "

Stand on the application side of the point of view, no matter what kind of technology, the most important is to look at the price. OSRAM LED expert Liang Yuhua believes that the current price of the chip packaging system or system has no obvious advantages, even more expensive than traditional packaging technology. More intensive advantage is smaller in size, used in some high efficiency high density areas. "

The question is, what is the size of the chip packaging market?

Hongli opto electronic engineering technology center director Li Kunzhui said, because the advantages of chip scale package light angle, this year will burst some alternative market, market share will be about 10%.

From the lighting market, most of the commercial lighting or preference for small and medium power, and chip scale package are mainly concentrated in high power, medium power if it is necessary to go through the chip scale package is debatable. OSRAM LED expert Liang Yuhua said, "the future of small and medium-sized lighting power ratio will exceed 60% or higher, while in power or COB will drop to 40%, large power accounted for only 20%, only a part of high power field to replace free packaging technology, the proportion is about 10%. "

In the field of TV backlighting applications, the current brand of a fist product 37 inches, millions of units, the number of devices required for each device is probably between the number of 32 to 37, count down is the demand for tens of KK. Compared to the total lighting market and packaging market, the proportion of chip packaging is still very small. "Linyida also gives his own answer. (text / China LED network Lurena)
