A land grid array interposer structure, including an electrically insulating carrier plane, and at least one interposer mounted on a first surface of said carrier plane. For example, this disclosure relates to ultra concentrated liquid laundry detergent having superior water dispersibility at low temperatures. In addition, the fault detecting method and the layout method perform ordering of faults with their likelihood and weighting of the faults, taking into consideration physical information on a mask pattern within a chip or records of actual use of cells or functional blocks. Additional mechanisms are also provided for the return of remote resource management to the control of a previously failed, but now recovered node, even if the failure had resulted in a node reset.
