A fastener assembly including an elongate fastener adapted to extend through a chamber having a longitudinal axis, a first end and a second end; a first seal disposed at least partially at the first end of the fastener to prevent leakage of fluid from the chamber; and a second seal disposed at least partially at the second end of the fastener to prevent leakage of fluid from the chamber. The modules include cover layers. HCl is used in part to reduce corrosion and improve selectivity. The first conductive element may be substantially parallel with the second conductive element. The pre-defined protocol includes using the location frame having the pre-defined frame structure.
