BS IEC 62899 discusses printed electronics. BS IEC 62899‑202‑3 belongs to BS IEC 62899 multi-series and discusses the measurement of sheet resistance of conductive films by the contactless method.
BS IEC 62899‑202‑3 defines terms and specifies a standard method for the measurement of the sheet resistance of printed conductive films using a contactless eddy-current method.
BS IEC 62899‑202‑3 printed electronics is useful for:
Conductive films, transparent or non-transparent, are a key element for electronic products. The most used method for the measurement of the sheet resistance of conductive films is the 4-point probe measurement. For some devices or films which are covered with an insulating layer or composed of micro-/nanostructures, establishing an electrical contact is difficult. which makes the 4-point probe method not suitable for the measurement of sheet resistance.
BS IEC 62899‑202‑3 provides you with the method for measurement of sheet resistance using a contactless eddy-current method. The eddy-current-based measurement method does not require electrical contact.
BS IEC 62899‑202‑3 gives a brief explanation of the eddy-current-based measurement method and a comparison between 4-point probe measurement and Eddy–current measurement. BS IEC 62899‑202‑3 also gives test requirements, conditions procedures and parts to be mentioned in the test report. BS IEC 62899‑202‑3 helps you to manufacture high-quality printed conductive films.
