Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electronic products, and particularly relates to a substrate connecting rib structure. Background Art
[0002] With the rapid development of electronic products, the production of electronic products needs to consider production efficiency and production cost. At present, the main costs of the circuit boards of electronic products are various electronic components and the substrates required to carry the electronic products. Especially in high-power and high-performance circuit boards, due to the requirement of heat conduction, most substrates adopt high-heat-conductivity aluminum substrates or copper substrates. Therefore, the cost of the substrates accounts for a large part.
[0003] However, in the production process, the substrates of the circuit boards cannot be directly placed in the pick-and-place machine to mount components. It is necessary to splice several single substrates together with connecting ribs and supplement process edges around the substrates to form a rectangular circuit board substrate panel, which is convenient to run on the pick-and-place machine track. Since most high-performance circuit boards adopt high-heat-conductivity aluminum substrates or copper substrates with high costs, in order to reduce the usage area of the circuit board substrate panel and reduce costs, when making the circuit board substrate panel, several single substrates should be as close as possible when connected with connecting ribs, and only the necessary width for the cutter head of the board separator to cut is reserved between single boards. Manufacturers will cut off the substrate materials in the gaps between single boards and between single boards and process edges during processing. This is a necessary loss during substrate production. In high-heat-conductivity aluminum substrates and copper substrates, because the substrates are very expensive, the cost of this kind of loss is very high. Moreover, a relatively large distance needs to be reserved between single boards and between single boards and process edges, so the area of the entire circuit board substrate panel will also become larger, thus affecting production efficiency.
