The invention relates to the field of processing a printed circuit board and specifically relates to a forming processing hole for the printed circuit board for correcting a compensation factor. The forming processing hole is a slot hole and is formed at the edge of the printed circuit board; the forming processing hole is shaped as a concave groove; and two angular positions at the bottom of the forming processing hole extend toward two sides, thereby forming an arc-shaped groove. The forming processing hole for the printed circuit board has the beneficial effects that a milling cutter with the cutter diameter being 2.0mm is utilized to compensate the traditional forming processing slot hole for 0.1mm, and the milling cutter with the cutter diameter being 2.0mm is used for processing and producing the forming processing hole for the printed circuit board with convenience in USP slotting, increased production quality of the printed circuit board and forming operating efficiency (being increased by 17.3%).
Description
technical field [0001] The invention relates to the field of printed circuit board processing, in particular to a printed circuit board forming processing hole for correcting compensation coefficients. [0002] Background technique [0003] With the development of integrated circuits, the requirements for integrated circuit packaging have also increased, and the requirements for printed circuit boards (PCB boards) used in packaging are also developing towards higher wiring density, better electrical performance and thermal performance. . In order to meet the above requirements, the development of high-reliability via holes, forming and processing holes and other technologies is the key, which has a great impact on the density of wiring, electrical and thermal performance after packaging, and processing efficiency. [0004] In the PCB manufacturing process, the PCB shape forming and milling process belongs to the last stage of the processing process. At this time, mos...
