pta-one-slot-registered-one-not-registered Creating precise slot hole for screw placement in Eagle CAD can be a detailed process, as the software doesn't natively offer a direct "slotted hole" creation tool. However, through a combination of existing features and clever workarounds, users can effectively design and implement these essential mounting points. This guide will delve into various methods, drawing upon community expertise and common practices to ensure successful PCB design.
One of the most frequently cited methods for creating a slotted hole in Eagle CAD involves utilizing the milling layer (layer 46)making 'slots' in PCB's? (Eagle) - General Electronics. As noted in several discussions, this approach is particularly effective for creating plated or non-plated slots. The strategy often involves using a log pad or an elongated pad and defining its shape on the milling layer, effectively communicating the desired non-circular aperture to the fabrication house.2016年2月13日—I'm trying to make a PCB which mounts to a metal chassis with 4holesin the corner of the PCB.Screwswould be used to hold the board down ... Some users recommend placing two vias where the slot begins and ends, then setting the drill size of the pad to the desired slot widthHow to create plated slotted hole/cutout as a footprint in .... This creates the visual representation of the extended opening.
For creating slotted holes that are intended for mounting with screws, the dimensions are critical.Here attached an example from other commercial cad (Solidworks) where you create a straightslot, a counterboreslotor a countersinkslot. While Eagle CAD itself doesn't have a direct command for such features, understanding the fabrication process is key. Many PCB manufacturers prefer to have these defined as either milled features or as a series of closely spaced drill holes. Therefore, drawing the intended slotted hole shape using the poly/arc tools on a mechanical layer, such as the dimensions layer, can be a viable option, though it requires careful coordination with the manufacturer regarding the tool path for milling.
Another common technique mentioned is to leverage existing hole types and manipulate their properties. For instance, when you need to make a through hole slot without a dedicated tool, placing two standard holes at either end of the desired slot and then using the milling layer to connect them or define the shape can be effective.making 'slots' in PCB's? (Eagle) - General Electronics Some users have even reported success by using a unique hole size that approximates the width of the slot and placing them strategically2013年6月4日—I'm looking for a way tomake a through hole slotinstead of a drill for the DC power jack connector pins (DCJ0202 from con-jack library).. This workaround, while not a direct solution, often serves the purpose when importing into Eagle CAD.
It's important to acknowledge that slotted holes in EAGLE are a nightmare for everyone for some designers due to the lack of a direct feature. This has led to a variety of creative solutions over the years.Prototyping Board Design - PCBs - Digital Concepts One such method involves using libraries that contain pre-defined slotted pad shapesCutouts and Slots In Eagle. While Eagle does not support oblong holes natively in its standard pad creation menu, custom libraries or user-created footprints can bridge this gap. The holes.lbr library, for example, offers various plating options and hole sizes that can serve as a starting point or template for non-standard dimensions if you need to make holes.How to create plated slotted hole/cutout as a footprint in ...
When considering plated slots versus non-plated slots, the fabrication process plays a significant role.Dimensioning slotted holes - YouTube Plated through-hole (PTH) slots are typically achieved through milling and subsequent plating. Non-plated through-holes (NPTH) might be achieved through simple milling without plating. Understanding the distinction between PTH and NPTH is crucial when defining your slots holes requirements.How to define cutouts and slotted holes in Eagle ... Many design discussions highlight creating these features using milling (layer 46), a technique that ensures the manufacturer understands the intent for both slotted and round holes.
For specific components like DC jack connectors that often require a through hole slot, users have detailed their approaches. This often involves ensuring the slot dimensions are correctly defined on the milling layer to accommodate the connector pins. Some have found success by creating a rectangular pad and then using the milling layer to achieve the desired elongated shape. This is a practical application of defining slots for specific electronic components.Cutouts and Slots In Eagle
Ultimately, successfully implementing a slot hole for screw in Eagle CAD relies on a robust understanding of the software's capabilities and limitations, coupled with good communication with your PCB manufacturer. Whether employing the milling layer, using strategically placed vias, or leveraging custom libraries, the goal is to clearly define your design intent for these crucial mechanical interfaces. The broader concept of slots in PCB design is not limited to mounting; they can also be used for wire routing, heat dissipation, or aesthetic purposes, further emphasizing the need for accurate representation within your Eagle CAD design.How to Make Oval or Slot Holes on PCB? - Layout
