7628 electronic fiberglass fabric prices china tells you that trace metal impurities in the electronic fabric should be eliminated. 7628 electronic fiberglass fabric prices china tells you that the electronic fabric contains conductive impurities, which is an important reason for the poor electrical insulation performance of printed circuit boards.

7628 electronic fiberglass fabric prices china tells you that for this reason, the manufacturer has installed a special metal content detection device on various glass fiber twisting machines to identify glass fibers that contain any metal within a diameter of 4m or more and a length of 2mm textile yarn.
7628 electronic fiberglass fabric prices china tells you that if any metal content in the textile yarn exceeds the specified standard, the sensor and the diode indicator light on the amplifier will automatically send out a signal, at this time the spindle of the twisting machine will automatically stop running, and the The twister will remove it and handle it separately.
7628 electronic fiberglass fabric prices china tells you that it can ensure that the textile yarn exceeding the standard does not flow into the weaving process, thus ensuring the electrical insulation of the electronic fabric. This method is called the LC oscillator method.
7628 electronic fiberglass fabric prices china tells you that some electronic fabric manufacturers use the microwave method (non-destructive detection method) or variable frequency discharge method (destructive detection method) in the surface treatment process. The detector is installed on the surface treatment unit, and it will start immediately when the detector finds that the electronic cloth is abnormal.
