– Definition of Component Sum
Component Sum = (S placed Components + S errors) 4
– Definition of Total Component Rejects
Total Rejects = (S Identification errors + S Vacuum errors) 4
– Definition of Total Rejects %
Rejected % = (S Total Rejects / (S placed Components + S errors)) * 100 4
– Definition of Vacuum Error %
Vacuum Error % = (S vacuum error / (S placed Components + S errors)) * 100 4
– Definition of Identification Error %
Identification Error % = (S identification error / (S placed Components + S errors)) * 100 4
4.2.3.1 Possible discrepancy between SIPLACE Explorer and OIS placement data
The number of consumed components, rejects and boards may differ between SIPLACE Explorer
and OIS. 4
In OIS each data record has a timestamp (consumed components, rejected components and each
board). If an OIS query is sent via SQL Query to OIS, for the consumption quantity within a certain
period, it will return the number of component records which have a timestamp within the specified
period. 4

SIPLACE Explorer assigns the components to the boards on which these have been placed. If a
query is sent to SIPLACE Explorer for the consumption within a certain period, it will return the
number of components which were placed on the boards produced during the specified period.
This difference is most obvious in production runs using 2 placement areas. 4
The following diagram illustrates the difference. 4
Example: 8 boards are produced by a machine with 2 placement areas. The diagram shows three
timelines: 4
– Components for placement area 1
– Components for placement area 2
–Boards
The components X, on the timeline for placement area 1, show the possible timestamps for com-
ponents which have been placed on board X. 4

If an OIS query is started via SQL Query for the period between T1 and T2, this will return the total
number of components which have been placed on all 8 boards, minus the number of compo-
nents, which were placed on board 1 in placement area 1. 4
If you start the same query via SIPLACE Explorer, this will return the total number of components
which were placed on all 8 boards. 4
In this example, the quantity returned by SIPLACE Explorer will be higher than that from OIS. 4
