工具孔(Tooling Hole)是PCB设计中用于制造过程中辅助定位和固定PCB板的孔。这些孔在PCB的制造、组装和测试过程中起到关键作用,它们帮助确保电路板在这些过程中能够准确对齐和固定。工具孔通常位于PCB的边缘或特定位置,不参与电路的连接,但对于确保电路板的质量和性能至关重要。 一、工具孔(Tooling Hole)的设计要求 位...
ipc中对tooling hole的定义在IPC(电子行业联合会)中,tooling hole被定义为用于定位、固定或支撑PCB(印刷电路板)上的元件或组件的孔。这些孔通常在PCB制造过程中形成,并在后续的装配和焊接过程中使用。 Tooling hole的主要作用是提供定位和固定,以确保元件或组件在PCB上的正确位置和稳定性。这些孔通常在PCB的设计阶段...
工具孔， 例如，用来做为定位孔，如钻孔，阻焊，成型，曝光等
The dedusting tooling can lead the PCBs to be kept at a fixed angle, so that a high-pressure wind gun is always to be vertical or vertical approximately, and the high-pressure wind gun is in parallel with through holes on the PCB, therefore, better dedusting effect and higher dedusting ...
Circuit board positioning hole refers to determining the specific position of PCB via hole in the PCB design process, which is a very important link in the PCB design process. The function of the positioning hole is the processing reference when the printed circuit board is manufactured. There ...

If PCB does not have any fiducials, we can add special fiducials with SMT Reflow Pallet & same can be use in Laser cut stencil. Printing Carrier for Flexible PCB Single / Double Sided assemblies with Through Hole technology can be soldered using the Wave Soldering machine in conjunction ...
He doesn’t say what material he intends to use, but it’s likely some type of fibre reinforced plastic. He claims the rigidity is close to that of die-cast aluminium. One addition we would like to see is some plugs for the unused hole to prevent small components from falling into ...
