Product Bin and Labeling Definitions Designing with SignalSure Flux bins supportable for car programs depend on product color and program start- and end-of-production date. Flux roadmaps by year and product color are maintained and available from the sales representative. Please contact local sales representative to request the flux bin range with best supportability for program timing. Decoding Product Bin Labeling In the manufacturing of semiconductor products, there are variations in performance around the average values given in the technical datasheets. For this reason, Lumileds bins...
