IEC 61338-4-2005 pdf – Waveguide type dielectric resonators – Part 4: Sectional specification.
2.2.1 Outline drawing and dimensions The detail specification shall include a dimensional drawing of the waveguide type dielectric resonator and/or reference to an appropriate international standard, to permit easy recognition and to provide information for dimensioning and gauging procedures. The dimensions shall include the overall dimensions of the body of the component and the size and spacing of the terminations. All dimensions shall be stated in millimetres. 2.2.2 Marking The detail specification shall prescribe the content of the marking on the waveguide type dielectric resonator primary package in accordance with 2.4 of IEC 61338-1. 2.2.3 Ordering information The detail specification shall prescribe that the following information is required when ordering a waveguide type dielectric resonator. a) Quantity b) Detail specification number, issue number and date and where applicable c) Nominal frequency in MHz or GHz d) Full description of any additional requirements to identify the waveguide type dielectric resonator. 2.2.4 Additional information (not for inspection purposes) The detail specification may include information which is not normally required to be verified by the inspection procedure, such as circuit diagrams, curves, drawings and notes needed for clarification. 3 Capability approval 3.1 Eligibility for capability approval Prior to making an application for capability approval a manufacturer shall first obtain manufacturer’s inspection approval in accordance with QC 001002-3. The primary stage of manufacture shall be as defined in 3.2 of IEC 61338-1. 3.2 Structural similarity Structural similarity is not applicable to capability approval. However, it is applicable to released lots as defined in 3.14.1 of this specification.
The CQCs shall comply with the following requirements: a) the range of CQCs used shall cover all the processes, component types and limits of the declared capability; b) the CQCs shall be one of the following: – waveguide type dielectric resonators in production; – test pieces designed for assessment of a process or range of processes; – a combination of both of these. When CQCs are designed and produced solely for capability approval, the manufacturer shall satisfy the NSI that the same design rules, materials and manufacturing processes will be applied to released products. The CQC specifications may refer to internal control documentation which specifies production testing and recording in order to demonstrate control and maintenance of processes and boundaries including the use of SPC procedures where appropriate. 3.5.1 Process The CQC specifications shall include the following processes to be assessed. This list is not exclusive: – sintering see 220.127.116.11 – deposition of electrodes (when applicable) see 18.104.22.168 3.5.2 Boundaries CQCs shall demonstrate a set of boundaries which shall include the following: – Temperature range see 22.214.171.124 – Ageing limits (when claimed) see 126.96.36.199 – Climatic category see 188.8.131.52 – Mechanical test severities see 184.108.40.206 This list is not exclusive. Where additional boundaries are claimed these shall be covered by one or more CQCs. 3.6 Inspection requirements for CQCs The inspection requirements shall be contained in the CQC detail specifications together with environmental tests, measurements, severities and end point limits, where appropriate (see 3.11). Where possible the tests applied to CQCs shall be selected from Clause 4 of IEC 61338-1. For capability approval and the subsequent maintenance of that approval, the inspection requirements shall ensure that processes and design features meet the declared capability.
3.8 Capability approval report The report shall contain the following information; – the issue number and date of the capability approval manual; – a programme for capability approval in accordance with 3.7; – the test results obtained during the performance of the programme; – the test methods used. The report shall be signed by the Chief Inspector as a true statement of the results obtained and submitted to the NSI for approval. 3.9 Abstract of description of capability The abstract, is intended for formal publication in QC 001005 when capability approval is granted by the National Certified Body (NCO) on the recommendation of the NSI. It shall include a concise description of the manufacturer’s capability and give sufficient information on the technologies, methods of construction, packaging and range of products for which the manufacture has been approved. The layout shall conform to Annex A of this specification indicating the boundary conditions for which approval has been granted. 3.10 Modifications likely to affect the capability approval Any modification likely to affect the capability approval shall satisfy the requirements of Clause 4 of QC 001002-3. 3.11 Initial capability approval The test plans given below are to be applied to appropriately selected groups of CQCs. The test plans are in categories as follows: a) Process CQCs b) Boundary CQCs The tests referred to in each test plan are defined in Table 1. These tests have been grouped to prove particular design areas covering materials, processes, resonator performance and durability.
