16.1 Introduction
Apart from technical malfunctions occurring in SMD production, mainly problems originating in the organizational
environment are likely to arise. These frequently result from missing components, inadequate information flow
and imbalances in the workload on the stations of a line. Prerequisite for the efficient elimination of these weak
spots is a profound knowledge of their underlying causes which can only be determined through continuous
automatic monitoring of the system.
The Ma
chine Data Management System (MaDaMaS) collects all relevant data of the line and offers the
possibility of a graphical representation of the production line status. It is thus possible - as soon as a PCB has
exited the line - to obtain a current display of the operational status of a complete line or individual stations.
This allows the user to swiftly take appropriate corrective action in the case of malfunctions, errors or
imbalances.
The present MaDaMaS version allows all logged production data to be evaluated taking one of the following
three time intervals (time base) as the basis:
- Evaluation from the time of the last set-up changeover to the present
- Evaluation from the time of the last PCB type changeover to the present
- Evaluation from the time of the last reset to the present
The evaluated data allow assessments to be made related to the following subject areas:
- placement performance (track errors, "good" placements)
- breakdown of the total processing time of a PCB into different status classes
(running, waiting, blocked, interrupted, failed)
- logging of automatically detected malfunctions
Each station automatically collects all data of "good" placements as well as track errors occurring during the
assembly of a PCB. Moreover, specific machine states are recorded with the aid of time meters.
