Mobile phone touch screen insulation resistance test

In the field of consumer electronics, especially in an environment where mobile phones and other devices are so popular, the insulation resistance of the device (the resistance value measured by applying a specified voltage to the insulating part) is directly related to the safety of the device itself and the user of the device.
In addition to insulation resistance, the resistance, inductance, interlayer short circuit and other characteristics of the mobile phone coil also need to be precisely measured, and the resistance test needs to be accurate to the milliohm level. Tonghui Electronics has built the following solutions for mobile phone coil manufacturing customers, which can meet all needs.
