SERIES ASA
The process of manufacturing ASA-SMD series of Automotive Grade Surface Mount Microprocessor Crystals is
performed by using
Advanced Product Quality Planning (APQP).
This technique defines and establishes the
following actions:
Product design activities communicating special characteristics to the process design activity, prior to design
release, linking the DFMEA to PFMEA.
Plan, acquire and install appropriate process equipment and tooling based on design tolerances provided by
the customer. – CPPD (Collaborative Product Process Design)
Assembly personnel communicating suggestions on better ways to assemble a product prior to the completion
of the design of the product. – DFA/M (Design for Assembly and Manufacturing)
Manufacturing or Process Engineering establishing adequate Quality Controls for features of a product or
parameters of a process, which still risk potential failure. – Control Plan Methodology
Performing Stability and Capability studies on special characteristics to understand the variation present and
predict future performance. – SPC (Statistical Process Control and Process Capability)
Request for
Production Part Approval Process (PPAP)
documentation must be requested at time of
order placement. Requests for part approval will be supported in official PPAP format and with
documented results as requested at time of order placement. Actual measurements are taken of the
parts produced and are used to complete the various test sheets of PPAP.
NOTICE
If you intend to use our product referenced above in an automotive application that may result in loss of life or assets, please do
not fail to advise us of your intention beforehand. The use of the listed part in those applications is not covered by warranty,
and we will not be held accountable for any liability claims. We reserve the right to not supply parts in those circumstances.
