Maintenance Plan
Chapter Issue 2, July 16 Maintenance Manual 1.7
Accuracy Check The accuracy check should be performed after doing 10 cycles unmeasured,
allowing the machine to settle. Month 1 and Month 7 are 100 cycles, all other
months are 30 cycles as shown in the table below.
Pre and Post print measurements are taken to record the accuracy of the
alignment in CPK values and the front and rear squeegee pressures.
SPC Results Where the QC Calc for Windows program is installed, SPC data capture can
graphically show critical alignment and squeegee pressure accuracy. The
graphs in their visual form are often useful in determining the optimum mainte-
nance plan.
NOTE
Customers may opt to use the collected data in their own management system,
ASM cannot provide support for this.
Examining the
Collected Data
In addition to examining the SPC data which is displayed graphically in the QC
Calc for Windows program, engineers can extract information about machine
performance from other sources.
The SPC data collected on the machine is stored in E:\config\readings.dek.
Information can be displayed in a text editor and specific data can be examined
eg, events between dates or a specific word or phrase.
Each occurrence of an error for example, can be examined to see if the rate at
which it has occurred has increased (is it a random occurrence or an increasing
trend?).
Authorization At the end of each monthly task a Summary/Remarks form is provided to allow
the engineer to make comments or express observations. The engineer must
sign off and date the form on Page 1 so that there is a record that the schedule
has been completed.
