Screw Terminal 3D View - Wrong
382 3
Marco33 1 year ago
I am working on a project that has three types of screw terminals. \- 3Pin 2\.54mm Pitch from [https://jlcpcb\.com/partdetail/Dibo\-DB125\_2\_54\_3P\_GNS/C918121](https://jlcpcb.com/partdetail/Dibo-DB125_2_54_3P_GNS/C918121) From PCB 3D View wires enter from top. This seems correct.  The small rectangles on top of the pads suggest wires from top. Yes. A plain rectangle on the bottom of the pads. \- 2Pin 5\.08MM Pitch from [https://jlcpcb.com/parts/componentSearch?isSearch=true&searchTxt=C480516](https://jlcpcb.com/parts/componentSearch?isSearch=true&searchTxt=C480516) From 3D View wires enter from bottom. This seems wrong. Wires from bottom. The small rectangles on top of the pads suggest wires from top. No. Also, a plain rectangle on the bottom of the pads. \- 2Pin 3\.81mm Pitch from [https://jlcpcb.com/parts/componentSearch?isSearch=true&searchTxt=C89123](https://jlcpcb.com/parts/componentSearch?isSearch=true&searchTxt=C89123) From 3D View wires enter from bottom. This seems inconsistant and wrong. Wires from bottom. A plain rectangle on the bottom of the pads. Put these three on a schematic.  Convert schematic to PCB. Look at 3D View. You will find conflicting positions for the entry direction of the wires.  Something is wrong. Is the 3D Viewer wrong? Are the footprints wrong? How to reconcile? <br> <br>

'Put these three on a schematic.  Convert schematic to PCB. Look at 3D View.' . OK, I did... . ![SCREWS_01.jpg](//image.easyeda.com/pullimage/3wSwhPlVhxD0AcCF7ZQrP5PfQss6ZiCSNYrgn4vD.jpeg) . . Apart from rotating SCREW #3 180° this is out of the box. . Regards. MrToM.

Hi MrTom See these inconsistancies. Screw #1 wires go away from the three small rectangles on the footprint. Screw #2 wires go toward the three small rectangles on the footprint. Screw #3 no small rectangles. These are directly from the LCSC library. Totally inconsistant.

Hi Marco33, I see your point and agree it's not easy to deduce cable entry from just the footprint alone. . Bear in mind though that each footprint is unique to its respective component and reflects the details within it, three different manufacturers of a similar component will produce three different components with differing details. . You can of course edit a footprint or create your own if you find them confusing. . Regards. MrToM.
