10.5.2 Pressure recorder PCB (printed-
circuit-board) replacement
This approach (Boothroyd et al., 1994, Huang 1996) has been used to
study the service disassembly and reassembly processes by identifying
all individual steps including part removal, tool acquisition, pickup
and orientation, and insertion. The time standard in this procedure is
the result of Abbatiello (1995) at the University of Rhode Island. An
exploded view is given in Fig. 10.7. The worksheets in Tables 10.5 and
10.6 were developed to utilize the serviceability time database. The
first step of the DFS approach is to complete the disassembly work-
sheet in Table 10.5. The DFSS team may disassemble the pressure
