Big talk about what CSP can extend the application areas?

Since entering in 2015, the LED industry on the application of CSP lighting lamps gradually high, is believed to be the life of leather LED packaging factory subversive products"!

LED application based on the direction of the wind began to bias CSP, many companies began to layout CSP, for fear of leaving the CSP will be abandoned by the application of the danger.

But is not all packaging enterprises have capital, ability (technical capacity and equipment capacity) CSP layout? For traditional packaging enterprises, because it has been committed to installing LED, there are advantages in the field of production, richly endowed by nature in the application process, the market there are huge groups of application. When CSP comes, has been engaged in the packaging industry enterprises, large enterprises, listed companies have been involved in to seize the initiative, don't want to break in period.

But for small and medium sized packaging enterprises, is not to say that you can easily switch to switch, because companies have been massing and small, narrow application group, revenue is limited, if the following R & D investment in CSP, rectification equipment, equipment, technology and so on major action, driving the funds, products are high risk and uncertainty expansion. It is more difficult to make a choice, the current development of CSP is still in the initial stage, the advantage is not obvious. Fried hot CSP contrast to the current form of packaging, CSP packaging there are still several difficulties:

1, light effect design is not a cost-effective chip;

2, with the power of the light effect, dress chip yield and technical maturity than the current CSP more advantages;

3, with the effect of light flux output, also have the advantage of dress;

4, lighting manufacturers on the use of CSP SMT.

In view of this, the lighting industry elite alliance WeChat group in November 29, 2015 in the "elite perspective" column on the CSP what are still unknown and pending technology? In addition to the traditional CSP in the traditional flash, backlight display to play a dominant role in the field of lighting, such as whether people expect ideal, and other issues were discussed. Chen Yong, general manager of Shenzhen City, a new bright spot as host of this period. China semiconductor lighting network as a support media, with a view to further communication and interaction within the group of CSP technology, to the future development of the industry and enterprises can help. The following is a participant in the discussion (for reference only):

Elite view

1:CSP LED status?

Solution: Chen Yong (general manager of Shenzhen new bright spot Electronics)

The full name of CSP is ChipScalePackage, which means chip level package, chip size package.

CSPLED status: 1 light effect is not high; the reliability of the 2 to be verified; the price of the high side of the 3; 4.ESD level is low; the application of the 5 end of the high accuracy of the installation requirements of high mounting costs.

In response, Yuan Haihui proposed the general manager Fu CSP has those advantages, Chen Yongru replied: "no CSP chip three main structures: 1 by silica fluorescent powder pressing, five surface light, high light efficiency, but the uniformity of color temperature control is poor at the top and around the top 2; a light emitting surface (single light), surrounded by titanium dioxide coated fluorescent protective film, light consistency and directivity is very good, but the loss of output light around the light effect is still insufficient; 3 with fluorescent film full coverage, plus a fixed transparent silicone molding, light quality slightly worse (anisotropic color consistency is not good)".

In response to the question of the million photoelectric Zhang Dongyuan also mentioned, because through the back plating, so that the reflection cavity or the bottom of the quantum wells are involved in the issue of patent. But from the application side to see the current 28359v100mA1w products do between 0.11-0.16RMB, CSPLED also need a long time to settle in order to achieve this price. CSP currently in the backlight, the application of flash in the rapid increase in the future in the UV, lighting, landscape lights, lights and other applications are also expected to complete the replacement of existing light sources. As indoor 30W following products are likely to replace some of the SMD and cob market.

CSP used in the flash, the main use of CSP slim, small size, light time only in an instant.

What are the areas of application of 2:CSP technology after the question of maturity?

Solution: Chen Yong (general manager of Shenzhen new bright spot Electronics)

It does not affect the entire packaging industry, but the mainstream form of packaging industry. It belongs to the technical aspects of the chip update, and does not belong to the packaging world. Just a product form, is a supplement to the entire LED product category, the short-term will not cause too much impact on the overall packaging situation. Of course, the existing packaging plant still has its existence value, and in the CSP product yield and cost problem has not been solved before. In the field of lighting, SMD packaging of the high cost of technology will still be the mainstream, can be expected at least 3-5 years was dominated by SMD, CSP yield problems also engage in about 3 years, from the current number of CSP plant yield roughly estimated at around 70%. So packaging enterprises do not scare themselves to death.

2016 packaging enterprises strive to improve the efficiency of the machine, the elimination of low production equipment, improve the yield through technical improvement is the focus. After the mass production of CSP applications, the price should not be a problem, mainly CSP yield problem now, in theory should be able to do lower prices than SMD.

What are the problems of 3:CSP in large-scale lighting applications?
