Notification of Removal of Device Backside Mark on all Lattice QFP Products Lattice is providing this notification of our intent to remove the backside marking for Lattice Quad Flat Pack (QFP) products. The backside marking removal will be a gradual transition until existing inventories have been exhausted. The manufacturing process will be changed on or after December 28, 2020 and the realization of the removal by the customer will be a gradual transition over time, depending on the individual products' inventory levels. Backside marking consists of the Date Code (YYWW) and Assembly Lot number. These are both being marked in package assembly. Currently, backside marking is utilized only for internal traceability. The device and assembly lot will maintain traceability with the Inspection Lot (topside lot number). The change is aimed to standardize with current industry practices.
As you may be aware, Lattice recently announced PCN 07A-19 which addresses an alternate source qualification for certain Lattice devices.This was issued to address the unexpected and sudden plant closure of our sub-contractor facility at Unisem Batam. The devices listed in that PCN were sole-sourced at the Unisem factory and must be re-qualified at ASE Malaysia.In addition to the sole-sourced devices identified in the above PCN, Lattice has an additional list of devices which are dual-source qualified between ASEM and Unisem. Lattice has been shipping from both factories for these dual sourced devices for many years with equivalent high quality.Given the unexpected timing of the Unisem closure, Lattice is shifting our allocation of both raw materials and assembly builds from Unisem to ASEM.
