Hi Steve

Our application is essentially to boost current carrying capacity without
the need to increase the size of the housing (marketing requirement). We
need to provide a high current path from pcb to bulkhead mounted connector.
The wires are insulated and can withstand the ends being tinned and
soldered. ie the insulation type has been appropriately selected. The
length of wire is 4 to 6 inches. Due to the compact nature of the design,
there is no physical height for through-hole slid on terminal points on the
pcb on which to attach wires with a crimped "spade lug". My concerns are
the reliability of the large soldered wire joints to the pcb - during
assembly or servicing will an unacceptable force be applied to the solder
pad. The assembly process if this is acceptable is slow, but acceptable to
production. I am also concerned with the ability of the operator to repeat
the process hundreds of times per day, with the same level of consistency.
As in most engineering solutions we appear to be looking for a compromise,
I want to ensure a reliable one.

Greg
