Second source is the term given to the possibility of using different suppliers for a product in a particular project or for a product series. It should be possible for the products to be incorporated in current production without incurring additional costs. Second source is standard practice for LED components because of the greater security of supply but components from different manufacturers generally differ in terms of their dimensions and the shape of their solder pads. This is why two boards are generally needed for the LEDs from two different manufacturers. This drives up costs for storing the boards and also for modifying the process.
For ceramic LED components, to which the entire Oslon family belongs, Osram Opto Semiconductors in Regensburg has therefore developed a concept that makes the board solder pad design so adaptable that it can be used for LED components from at least two different manufacturers. The concept can also be used for metal core, FR4 and ceramic boards.
