7.4. Production
7.4.1. Production planning
To achieve the quality required by ASM AS, the supplier must apply a systematic planning of the manufacturing
processes. This is part of the quality management system used by the supplier. Each step in the manufacturing of the
product to be supplied must be documented in work and process instructions.
7.4.2. Production and assembly equipment
The use of suitable production and assembly equipment must be planned at an early stage in order to ensure that the
equipment is available with sufficient capacity at the start of the series production. The employees must be adequately
trained for the application.
Service and maintenance of the equipment must be planned in a preventive manner. Evidence of the systematic and
consistent application shall be furnished.
The supplier must establish and maintain an emergency strategy for the processes that could prevent his capability to
deliver.
7.4.3. Test planning / test methods / test equipment / statistical methods
The protection of quality with the suppliers must be so reliable that an adequate control of the manufacturing processes
(process capability) is achieved to meet the agreed requirements.
The extent of testing during the manufacturing process shall be planned and defined according to the degree of the
achievable and achieved process capability, the respective quality attribute and the possible impact of faults.
The tests shall be documented so that the supplier can prove at any time that the specified requirements were met over
the entire manufacturing period.
The application of statistical methods (e.g. SPC, MFU) serves the evaluation and proof of the quality capability of relevant
process and product attributes. They enable the user to detect changes in the process faster and to correct the impacts on
the customer’s product at an earlier stage.
For further details on process capability and SPC, see ISO 11462-1 and 11462-2
Process FMEA:
To ensure that the manufacturing process is free of errors, ASM AS expects its suppliers to perform a process FMEA. This
is designed to detect sources of error and to enable preventive measures to be taken to avoid errors.
Testing equipment:
The testing equipment used must be sufficiently accurate in respect of the specified tolerances. The measurement
uncertainty of the measuring equipment used must be taken into account. The supplier must ensure that the measuring
equipment used for quality assurance is inspected and calibrated at specified intervals.
Analyses of the measurement systems must be used to ensure that the measuring equipment and devices used are
capable of providing meaningful measurements in the context of statistical process regulation and process capability
analyses. Any deviations and uncertainties in the measurement system that arise must be appropriate in relation to the
threshold values and to process variance.
The supplier must ensure that any variance that does arise during series measurements cannot be traced back to any lack
of accuracy or precision on the part of the measuring system.
For further information, see Measurement System Analysis (MSA) Reference Guide TS 16949
7.4.4. Execution of Tests
Tests during production permit the early detection of faults as well as selective countermeasures. This helps prevent
negative impacts on the capability to deliver and reduce or avoid rejects and rework costs.
Purchased parts must be subjected to quality testing before use.
In-production tests shall be implemented for quality-relevant manufacturing steps.
In order to supply fault-free products in the sense of the “zero defects” quality goal, ASM AS considers it indispensable to
conduct a final test unless the quality requirements have already been adequately protected in the previous processes.
Functional modules must be subjected to a 100% functional test. The results shall be recorded as a “First Pass Yield”
report.
The rework / repairs performed on failed assemblies shall be recorded and evaluated by fault attributes.

7.4.5. Test records and safekeeping
Quality records furnish the evidence that the quality requirements have been met. They must be maintained so that they
can be evaluated and permit a clear assignment to the tested products.
The quality records must be kept in compliance with the applicable legal provisions. The responsibility for the proper
safekeeping lies with the supplier.
The records shall be made available for review to the representatives of ASM AS on request and serve as the basis for
cyclic quality reviews between the supplier and ASM AS.
7.4.6. First article inspections
The First article inspection must furnish evidence prior to the start of the series production that the quality requirements
that have been agreed and defined in drawings and specifications are met.
First articles are products that have been fully produced using series equipment under series conditions.
A sufficient number of First articles shall always be produced to enable an initial statistical assessment of the
manufacturing process. The selection criteria for the statistical analysis shall be coordinated with the Supplier Quality
department of ASM AS. At least 3 units shall be subjected to 100% testing of all attributes.
The number of First articles to be manufactured shall be specified by ASM AS in the order for the First articles.
This procedure serves the purpose of obtaining an initial statement about whether the production process is repeatable,
stable and capable with respect to the accuracy requirements.
A First article inspection must always be conducted for / in the case of:
• Parts / assemblies (new parts) manufactured by a supplier for the first time
• Major changes initiated by ASM AS according to the requirements defined in the change requests
• Product changes initiated by the supplier or his subcontractors if such changes have an impact on the form and
appearance, interchangeability or functionality as well as performance features
• Production relocations initiated by the supplier or his subcontractors with respect to function-relevant / critical
processes
• Changes of the production process at the supplier or his subcontractors with respect to function-relevant / critical
processes
• More than one year production interruption
In the case of production relocations and changes of production processes with respect to function-relevant or critical
processes, the supplier shall always notify ASM AS in order to coordinate the implementation and number of First articles
to be supplied.
As a rule, the order to produce First articles will be defined by ASM AS in the order or change request.
Inspection of the First articles according to the quality attributes that are defined in the drawings and specifications with
respect to dimensions, materials, functionality, appearance, surface quality, etc. in the form of a variable test (measuring
inspection) if possible. This may require the use of external services.
As a rule, the goal shall be process capabilities in the individual processes. The measuring and test results have to be
evaluated under this aspect.
Scope of First article inspections:
• First article inspection report results
• Documentation of test results using the forms provided for this purpose
Test results shall be recorded as set point (lower and upper) tolerance limits and actual value, in order to enable
their quick and easy comparison.
• Report results and test results shall be enclosed with the supplied goods so that they can be clearly assigned to
the numbered parts and are provided with the date / signature.
• Reports on life cycle, reliability or other special tests
• Clearly identified parts that can be clearly assigned to the documentation
• Material certificate
• Evidence of compliance with required legal provisions (e.g. environment, safety)
• Declaration of compliance with the specified requirements for purchased parts / components used
14 www.asm-smt.com
• Control plan that describe production process control
• FMEA for category A parts
• Packaging proposal for the serial production shipment
• Drawings showing the marked test characteristics (assignable to test result, e.g. by consecutive number)
The documentation can also be supplied by fax, email, Internet etc. in coordination with ASM AS.
Incomplete deliveries of First articles will result in the refusal of the First articles!
As a rule, all quality requirements must be meet. Non-compliance is not permissible!
Repeated refusals can lead to objections, which can in turn affect the supplier rating!
After the samples have been submitted and the First article inspection reports have been generated, the Incoming
Inspection department of ASM AS will conduct a counter-check. It is also possible to conduct a joint inspection at the
supplier after prior coordination.
The release of the samples does not dispense the supplier from his responsibility for the quality of his products.
The release of the First articles does not constitute a delivery order.
Approved First article forms include e.g. First Article Report see Appendix 11.1a and 11.1b.
First Article flow attached 11.2
Always check with Procurement Engineer / Supplier Quality Engineer for the specific first article requirements for various
commodity which is described in “First Article Submission and Requirement” document.
7.5. Identification and traceability, configuration documentation
Special attention must be paid to safety-relevant components and assemblies for reasons of product liability.
Failure to observe the minimum applicable regulations in the respective countries may entail severe pecuniary penalties,
recall or replacement campaigns or a sales ban in the case of quality defects.
In the event of a product safety incident, evidence of the properly executed tests and the traceability of the results must be
furnished for the affected components and assemblies.
In order to ensure the traceability of the supplied products, the supplier must clearly identify his supplied or manufactured
products relevant for the safety or functionality of the ASM AS products.
Where required by ASM AS, traceable documentation must be provided for systems and assemblies with respect to their
constituent components and subassemblies by means of serial numbers or batch numbers. The records must be kept in
compliance with the applicable legal regulations.
Form and content of the identification and documentation shall be agreed with ASM AS if not already specified in the
product documentation.
