- by Admin
IPC 620 is a common terminal crimping standard for industrial connectors, which is mainly used to connect various electronic devices to realize the transmission and exchange of electrical signals. This standard describes in detail the requirements and precautions in the process of terminal crimping to ensure that the crimping quality in accordance with the provisions.
Definition and role of IPC 620 standard
IPC 620 is a crimping standard for connectors in the electronics industry, which specifies the requirements for the crimping process, quality assessment and acceptance criteria to ensure the reliability and stability of electronic connectors.
IPC 620 standard scope of application
It applies to the crimping of various types of connectors used in the electronics industry, such as wire-to-wire, wire-to-board, board-to-board and other connection methods.
History and development of IPC 620 standard
With the development of the electronics industry, the crimping technology of connectors is constantly improving, and the IPC 620 standard is constantly updated and improved to meet the new technology and market demand.

Crimp terminal quality requirements and assessment
- Definition of crimp terminal quality: Crimp quality refers to the connector in the crimping process of process control and quality stability, including crimping strength, crimping position, metal deformation and other elements.
- Crimp terminal quality assessment methods: through visual inspection, X-ray inspection, tensile testing and other ways to assess the quality of crimping to ensure that the electrical and mechanical properties of the connector meet the requirements.
- Crimped terminal quality common problems and solutions: for the crimping process of common problems, such as poor crimping, metal deformation, insulation skin damage, etc., to take appropriate measures to solve the problem, such as adjusting the crimping parameters, replacement of crimping molds, and so on.

Acceptance criteria and process
- Formulation of acceptance criteria:According to IPC 620 standards and customer requirements, we formulate acceptance standards, including appearance inspection, size measurement, electrical performance test and other aspects.
- Implementation of acceptance process:According to the acceptance standards for connectors one by one inspection, record the results of the inspection and issue an acceptance report. For connectors that do not meet the requirements, rework or scrap processing.
- Precautions in the acceptance process: In the acceptance process, we need to pay attention to check whether the connector labeling and packaging meet the requirements, and pay attention to the problems that may arise in mass production, timely feedback and improve the production process.
Kaweei strictly follows the IPC 620 standard for terminal crimping, realizes zero defects in metal biting with nano-precision technology, ensures that each wire harness is as smooth as silk when energized and as tensile as a steel cable with military-grade quality control, and welds “reliability” into every connection point.
