The major difference during disassembly is the type of fasteners used for the PCBs:
Screws are used for the HS-50 (see Fig. 2.6.1) and spacer bolts for the S-25, F5HM and F5 HM,
in a like manner to that shown in Fig. 2.6.3. In addition, there is no head cover on the HS-50 as yet.

1. "old" Head PCB with processor board HS-50 (Conversion PCB, small axis" see Fig. 2.6.2)
2. Fasteners: 4 socket hex head cap screws M3 on the spacer bolts
3. Ribbon cables (are removed completely and replaced by cables from the retrofit kit)

1. 4 spacer bolts removed (fastening of the PCB unit), size 5.5 mm open-end wrench
Å Wear the ESD bracelet (see CAUTION text above).
Å CAREFULLY detach all connectors on the top of the "Conversion PCB, small axis" / on the
"old" Head PCB with processor board (on all placement heads).
Å In each case, remove the two wide and the narrower ribbon cable (see Fig. 2.6.1 -> 3) from the
placement head because they are being replaced by the new cables in the retrofit kit.
Å Set the remaining cables to one side such that there is no contact between them.
– For the S-23, S-25 HM, F5 HM:
4 spacer bolts on the "Conversion PCB, small axis" (see Fig. 2.6.2 / in like manner to that
shown in Fig. 2.6.3)
– For the HS-50:
4 socket hex head cap screws on the "old" head PCB with processor boards (see Fig.
2.6.1).
Å Lift the PCB slightly and unplug the 4 ribbon cable connectors on the bottom of the PCB.
Å Remove the PCB and place it in an antistatic package immediately.
