Quality Control for Auto Insertion machine manufacturing

   

Quality Control

 

 

Every Auto Insertionl machine
is subjected to a Quality Acceptance Test (QAT) before being shipped to
its customer. There are 4 phases to a QAT:

 

 

Phase I – Pre-Dry Cycle

 

The
appropriate pattern program is loaded and the machine performs a short
part run with all motions and mechanisms functioning to check setups and
speed. All data is recorded on the machine’s event log.

 

 

Phase II – Dry Cycle

 

Can
only occur after successful completion of the Pre-Dry Cycle. The
machine is run with all motions and mechanisms functioning but without
boards or inserting components for a pre-specified period of time. All
data is recorded on the machine’s event log.

 

 

Phase III – Integrity Run (Final Run)

 

Can
only occur after successful completion of the Dry Cycle. This is a
simulated production run to check insertion performance and speed.
Results are recorded on the machine’s event log.

Phase IV – Customer Acceptance (Optional)

 

Can
only occur after successful completion of the Integrity Run. The
customer visits the factory to watch verify the machine’s ability to
meet performance requirements. The customer’s production run is
simulated and all options are verified and explained.

Phase V – Preproduction Acceptance (At customer site)

 

Service engineer installs the machine and assures it is setup
and running with the same degree of operational efficiency as at the
factory.
