With the Process Optimization Device (P.O.D.)
service from SMT Research Inc., vision
assistance is used to measure components placed by your
placement equipment. After
inspection, the Service Engineer will then analyze the
placements. Then either suggest repairs
needed, or repair and mechanically adjust the machine
on site. Once placement variance is
reduced to within tolerance, the P.O.D.
system will then update all placement offsets. This
moves parts within the placement accuracy determined by
the OEM or your own specifications.
Here
are the steps we perform:
Statistically evaluate each machine’s current placement
accuracy and mechanical capability
utilizing customers set specification limits.
Evaluate and analyze process data to identify any machine
deficiencies.
Perform statistical calibration of machine’s X,
Y axis with respect to zero both with and with out
optical correction. This will also detect worn X, Y table
components.
Perform statistical calibration of machine’s nozzle
shaft offsets for Place Position X and Place
Position Y to increase machine capability and placement
accuracy.
Provide each machine’s placement accuracy (Cpk)
via collected raw process data for customer
to evaluate utilizing their own statistical software package
and techniques.
Submit to customer and review certified process data.
In addition, repeat what steps should be
taken in order to achieve and maintain an efficient production
process.
Address any other ongoing issues.
