PNP head: A clogged or dirty vacuum filter or silencer at this
vacuum generator can cause dropped devices and placement
problems at the PNP head.
Marking System: [Marking option] Two vacuum generators in
the Option Bay must be clean to ensure devices stay on the
marking shuttle.
Tape Output: [Output option] A clogged or dirty vacuum filter
or silencer at this vacuum generator can cause dropped devices
at the PNP Taping Head on the Tape Output Module.
1. Preparation—
1a. Use the Gantry Window to move the PNP head to an accessible
location.
1b. Shut off the PS System power and ensure the main power switch
is in the OFF position. See Turning Off the System on page 4-4.
WARNING: Electric shock hazard. Shut off the PS System
by
switching off the main power switch before working on or near
the PNP head, before opening any access doors or removing any
cabinet panels.
1c. Remove the two Vacuum Generator mounting screws with a
7/64 in. hex key and be ready to support it as it falls free. See Fig-
ure 4-12 below.
2. Check silencer and filter—
2a. Push the silencer out of the vacuum generator block (either
direction). If dirty or clogged, replace with new silencer
(Data I/O part number 288 5500 902). See the figure below.
2b. Unscrew the black knob on top the vacuum block and remove
the filter. It should be white or nearly white. If dirty or clogged,
replace with new filter (Data I/O part number 288 5500 901). See
