it may be necessary to clean sockets with low pressure, clean dry
air.
Blow out sockets every day. Refer to Inspecting the Socket Adapters
on page 4-8. Actuate the socket to blow out debris from beneath
the contacts. More frequent cleaning is recommended in a dirty
environment.
Bent or distorted contact pins can cause intermittent socket fail-
ures.
System Maintenance that Affects Yield
PSV7000 machine maintenance is critical to maintaining high yields.
Periodic cleaning, adjustment and replacement of worn elements
ensures the best possible performance. These periodic procedures are
outlined in Maintenance Schedule on page 4-2 and should be followed
closely.
Part of regular maintenance is ensuring that the system hardware is
in good working order, and that settings are accurate.
To check programmer hardware see FlashCORE Programmer Diagnos-
tics on page 4-28.
For accurate placement, ensure that workspace locations (also known
as a Package File) are taught correctly.
If throughput is down, perform Get Movetimes again: see Optimize
Movetimes on page 3-11.
Process Errors
Finally, some process errors can result in reduced yield. While an
automated approach eliminates most human error during produc-
tion, errors in setup or maintenance can result in reduced yield:
Using old algorithms may affect programming yields.
PSV7000 System algorithms are updated weekly at
http://www.dataio.com/algorithms/ and are available depending
on your maintenance plan. Algorithms are updated vis
TaskLink. See TaskLink Help for more information.
Selecting the wrong device part number for the job in TaskLink,
and therefore the wrong algorithm.
Selecting unintended programming processes in TaskLink (sec-
tor protection, security options, verify options, continuity test-
ing, blank checking).
Measuring yields too infrequently, so that a drop in yield rates is
not detected until a large number of devices have failed.

Socket abuse, such as digging failed devices out with sharp
instruments.
Changing to a questionable vendor source. Lower quality
devices tend to produce lower yields.

(Optional) Creating a Data File from
a Master Device
The PSV7000 System can read data from a master device and create a
data file (also called a PC File) that can then be used in programming
jobs.
For complete instructions on creating a data file from a master device,
see TaskLink online Help.
Figure 3-10: TaskLink’s online Help includes steps for creating a
computer file from a master device.
