Abstract:
Methods of manufacturing circuit boards and circuit boards formed thereby to have a surface that is configured to receive circuitry and a notch of a selectable configuration in a lateral edge along the surface of the circuit board boards, and where the selectable configuration is configured to convey identifying information relating to the circuit boards. Such a circuit board can be produced from a panel containing one or more circuit boards, wherein at least one circuit board has a border adjoined and defined by a partition feature that is configured to enable the circuit board to be physically separated from other portions of the panel. Notches having the same of varying selectable configurations may be formed on the at least one circuit board during the manufacturing of the circuit board.

The first outer electrically conductive pattern layer includes many first gold fingers. The second outer electrically conductive pattern layer includes many second gold fingers. The blind hole corresponds to the identification mark. The first outer electrically conductive pattern layer, the second outer electrically conductive pattern layer, and the at least one identification mark are simultaneously formed.
Abstract:
A method and system increase processed specimen yield in the laser processing of target material that includes multiple specimens formed on a common substrate. Preferred embodiments implement a feature that enables storage in the laser processing system a list of defective specimens that have somehow been subject to error during laser processing. Once the common substrate has been completely processed, the system alerts an operator to the number of improperly processed specimens and gives the operator an opportunity to run a software routine, which in a preferred embodiment uses a laser to scribe a mark on the top surface of each improperly processed specimen.
Abstract:
The present invention provides a routing structure and display panel. The routing structure includes a plurality of routing, disposed separately. Each routing corresponds to a symbol, and the symbol is disposed on the routing to act as a part of the routing to conduct electricity. In this manner, the routing structure and display panel of the present invention allow expansion of routing width, effectively reduce RC constant and energy-consumption, and improve yield rate.
