Notes: 1.These assemblies are ESD sensitive, ESD precautions shall be observed.
2.These assemblies must be clean and free from flux and all contaminants. Use of no clean flux is not acceptable.
3.These assemblies must comply with workmanship standards IPC-A-610 Class 2.
4.Install Bumpons on back side(unpopulated side) of PCB. Install one in each corner after cleaning.
5.Ref designators marked with an * cannot be substituted. All other components can be substituted with equivalent components of the MFG.
