OSRAM Oslon LED using unified pad design, greater flexibility brings two opportunities

LED is not all the same. Not only the performance data and the size are different, the pad and the procedure choice also have the difference. But recently, OSRAM Opto Semiconductors based on the Oslon family of products, developed the concept of unified pad, so that customers can more easily use the collocation of different manufacturers (second sources) the production of LED, reduce the storage and process improvement cost.

Second Source (Second) refers to the supply of a particular product or a series of products in a particular project by different suppliers. Using this strategy, all products should be able to integrate into the current production, and will not produce additional costs. In this way, the supply of higher security, LED components is the standard sourcing strategy. However, due to different manufacturers of components usually have different pad size and shape, so often need to use two types of circuit board welding two manufacturers of LED, so as to raise the circuit board storage and process transformation cost.

Circuit board layout

Considering the entire Oslon family of products are LED ceramics, OSRAM Opto Semiconductors in the German city of Regensburg put forward a new concept: the circuit board pad design, compatible with LED components by at least two different manufacturers. The same concept applies to metal core, FR4 and ceramic plate.

General lighting product development headquarters in Germany OSRAM Opto Semiconductors Oslon Project Manager Christian G by Dr. rtner explained: "just do a little adjustment to the process, can bring real and lasting benefits. "This kind of composite circuit board design is one of the two LED elements. A welding surface is divided into two parts: electrical connection and power cut. By reasonably choosing the distance between the welding surfaces, the second LED products (rotate 90 degrees) can be integrated into a unified circuit board design. The anode and cathode of the two LED elements are connected to the same electrical contact part. By dividing the weld surface, two types of LED are automatically aligned with the edge of the weld surface during reflow soldering. For the two LED element, the light emitting region on the circuit board in the same side, which is located in the plane of the circuit board with a line. If the two LED have the same emission performance, you can use the same two lens and reflector. This means that the characteristics of the LED component and the final application will not change.

Benefit maximization

With this new concept, do not have to modify the circuit board design, you can properly handle different manufacturers of LED components. In addition, due to the need to repeat the circuit board, the cost is further reduced. Christian G by rtner, the benefits concluded: "the efficiency and performance of the Oslon family of products is unmatched in the global scope, and pad flexibility in the design of this concept is to let our customers to get rid of the mechanical parameters of the restrictions, free to integrated OSRAM LED high power components second supply of goods. "

The improved pad design can be used to weld two different types of LED on the same board.
