CQI-17 is one of the special process assessment standards issued by AIAG (American Automotive Industry Action Group). Its full name is:
CQI-17: Special Process – Soldering System Assessment (SSA)
It is specifically used for quality management and process assessment of electronic soldering processes (such as wave soldering, reflow soldering, manual soldering, selective soldering, etc.), and is mainly used in the field of automotive electronics manufacturing (ECU, vehicle control module, circuit board, etc.).
Standard name: CQI-17 Soldering System Assessment
Current version: 2nd edition (released in 2020)
Language version: Officially issued in English, the Chinese-English version is translated by some companies
Purpose of CQI-17
Structure of CQI-17
The evaluation system of CQI-17 is divided into the following main parts:
1 Management Responsibility
2 Common Process Requirements
3 Soldering Process Tables
4 Appendix (Terminology, Inspection Diagram, Record Template, etc.)
1. Management Responsibilities (Section 1)
Is an effective welding training and certification system established (such as IPC-A-610 standard)?
Is there an internal audit mechanism (it is recommended to conduct self-assessment once a year)
Is there a traceability mechanism (welding batch, operator, equipment number, etc.)?
2. General welding process control requirements
Applicable to all electronic welding processes (manual soldering, wave soldering, reflow soldering, etc.):
Solder point inspection Including appearance standards such as bridge, cold solder joint, cold solder joint, solder bead, lifted foot, solder point morphology, etc.
Equipment maintenance Including regular cleaning and inspection of soldering iron tip, solder pot, nozzle, etc.
Anti-static control Whether there are ESD measures such as grounding, anti-static mat, wrist strap, ion wind, etc.
3. Sub-process tables (Process Tables)
CQI-17 has established 6 sub-process tables according to different welding processes, each containing control points and evaluation requirements for specific processes:
Table A Hand Soldering Soldering iron welding plug-in, cable, circuit board small batch welding
Table C Wave Soldering Batch welding of through-hole components
Each sub-process table contains:
Appearance standards comply with IPC-A-610 or customer requirements
CQI-17 evaluation items adopt AIAG general scoring method:
Soldering defects AOI automatic optical inspection 100% inspection
Antistatic Electrostatic wristband/ESD detector Daily power-on inspection
CQI-17 Scope of application
Tier 1/2 factories that perform reflow soldering, wave soldering, manual soldering, and cable soldering
Standard name CQI-17 Solder system evaluation
Latest version 2nd edition (2020)
Sub-process table Manual soldering, reflow soldering, wave soldering, selective soldering, flexible circuit, cable soldering
Evaluation cycle: self-assessment is recommended every 12 months
General standard comparison: IPC-A-610, J-STD-001, ISO 9001, IATF 16949
