Inspection of multipattern circuit boards. |
| 摘要 |
<p>Circuit boards with advantageous properties are produced through the addition of a fluorescent dye. The presence of the dye allows an expeditious inspection of the metallic pattern on the circuit board by induced fluorescence. If the circuit board is two-sided, to maintain the effectiveness of the dye, a material such as a light scattering composition is added to the circuit board substrate.</p> |
