HP 4062UX - Installing the SWM on a Wafer Prober; Automatic Wafer Probers; Manual and Small Automatic Wafer Probers

Installing the SWM on a Wafer Prober
The prob er manufacturer and the customer are resp onsible for mounting the HP 4085B/F
onto your wafer prober, and subsequent adjustment and service. Hewlett-Packard will,
however, provide technical assistance regarding SWM installation up on request. Contact your
nearest HP Service Oce for assistance.
Automatic Wafer Probers
Before you can install your SWM and HP 16072 Personality Board onto your wafer prob er,
mounting hardware|hinge, head plate, and so on|must be fabricated. For this purpose, the
dimensions and other mechanical sp ecications for the SWM and the p ersonalit y boards are
provided in the Pre-instal lation Manual .
Warning
Keep hands clear of the SWM, hinge, and wafer prober when lowering the SWM
into position on your wafer prober.
Caution
Do not touch the measurement pins of the SWM or the printed patterns of the
personality board. Oil, perspiration and dirt prev
ent go o d electric contact,
deteriorate insulation, and degrade measurement accuracy.
Note
After you have installed the HP 16072F Personality Board on your wafer
prober, adjust the p osition of the p ersonality b oard so the pin b oard n
umbers
printed on the p ersonality b oard line up with the corresp onding n
umbers on
the SWM. Conrm that all the measurement pins of the SWM are making
go o d electric contact with the pin contacts of the p ersonality b oard.
Manual and Small Automatic Wafer Probers
Because the SWM cannot b e installed directly on the manual wafer probers or small
automatic wafer probers, you need the Extension Cable Fixture (HP 16077A for HP 4085B
SWM or HP 16077F for HP 4085F SWM) to connect the SWM to the manipulator or probe
card of the prob er.
The extension cable xture installs onto the SWM and is secured in place b
y four thumb
screws. Wires from the manipulator or prob e card of the prober can then b e soldered to the
measurement pins of the extension cables xture. Figure 3-3 sho
ws the extension cable xture
with its protective cover plate installed.
For more information on the HP 16077A/F Extension Cable Fixture, refer to the HP
16077A/F Operation Manual .
Warning
Potentially hazardous voltages may be present at the measurement pins of the
extension cable fixture when the output enabled lamp on the SWM is lit. Mak
e
sure the protectivecover plate of the extension cable fixture is installed before
you operate the system.
