Embodiment Construction
[0017] Specific embodiments are given below to describe the content of the present invention in detail, and the accompanying drawings are used as auxiliary descriptions.
[0018] Figure 1A and 1B It is a schematic diagram of the printed circuit board of the present invention, and the printed circuit board includes: a substrate 110 , a conductive terminal (lead) 130 , a detection area 150 and a pigment coating 152 .
[0019] The conductive terminals 130 are arranged in a row on the substrate 110 , and one or more detection regions 150 are disposed between the conductive terminals 130 , and the detection regions 150 are covered with a pigment coating 152 .
[0020] Among them, the pigment coating 152 is preferably a paint with stable color; more precisely, the pigment coating 152 is not easily affected by environmental conditions (eg, temperature, humidity, etc.). In a preferred embodiment, the pigment coating 152 is resistant to chemical solvents, especially commonly used che...
