Leadtimes stretch
By Staff -- Purchasing, 2/15/2007 2:00:00 AM
Leadtimes for 37 of 41 electronic components tracked monthly by Purchasing stretched in January.
For instance, multilayer printed circuit delivery times went out from 6.5 weeks in December to 10.6 weeks in January andd-subminiature connectors stretched from 6.5 weeks to 9.4 weeks.
Leadtimes also stretched for rechargeable batteries. The average leadtime for a lithium-ion cell went out from 4.2 weeks to 9.0 weeks. Leadtimes also stretched for nickel cadmium and nickel metal hydride cells.
Leadtime lengthening should be short lived as first quarter demand should weaken.
