Solder pad patterns and shapes underneath lighting LEDs are not the same from different manufacturers,forcing users to re-lay their PCB if they change suppliers.
In a neat side-step,Osram is proposing a six-pad PCB pattern that will accommodate either the firm's own Oslon LEDs,or one from another manufacturer(see picture),making it easier for customers to second-source LEDs while only stocking a single PCB.
"For ceramic LED components,to which the entire Oslon family belongs,Osram in Regensburg has 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,"said the firm."The concept can also be used for metal core,FR4 and ceramic boards."
