Non contact technology -- open and short circuit test technology for electrical properties of ITO + Ag wire

in this paper, the design of ITO film and Ag lead is introduced+The electrical performance and function test is carried out after the sensor and other parts are installed.
if the ITO film or lead leads lead to open and short circuit, it is a great waste for the sensor on the bonding!) V + e n * '& B. M / I& B9 g2 \( K% J& g0 l! iThe company's ITO + Ag electrical performance short-circuit test can not only test the open circuit (single ended test point) and short circuit at one time, but also test after FPC bonding, so as to ensure the FPC, bonding effect, ITO film and Ag line short-circuit test, ensure that the subsequent production is carried out on the OK board, improve yield, reduce sensor loss and avoid waste of subsequent production cost.

is not a function test. It can detect the on-off and short circuit of ITO + Ag without sensor, so as to ensure that the upper and lower ITO are good products before bonding or before bonding with glass, and reduce the waste of sensor in the later stage! .

a, D! D* pI don't know what kind of equipment is used to inspect this part of each factory?
: lol.
what is the testing principle? Is it buried? .
