![]() So - while I'm still trying to find a way to make my videos look less half-assed - I encourage you to look at some much nicer ones. #Edge reflow tutorials how to#It shows how to use Reflow to define layout of. Defining Layout This episode covers the first steps of the Getting Started with Reflow tutorial series. It briefly covers the basics of Adobe Edge Reflow as well as navigation within the tool. #Edge reflow tutorials update#The impact of this is probably obvious to everyone (well everyone with more CSS experience than I have), but when you modify the base font size then all the elements using ems will correctly update relatively. Intro This is the introductory episode of the Getting Started With Reflow video tutorial series. You may notice that the base font is in pixels and other text blocks are in ems. One thing I didn't make clear in the video is how sizing works after you've done this. Next - check out the inline styling for text blocks:įinally, this video demonstrates how to specify base font settings for a document: There are many updates but in this blog post I'm going to demonstrate just a few of them that related specifically to typography.įirst, let's look at Typekit integration: Edge Reflow is a powerful prototyping tool for creating responsive designs. We can see the 20 mil clearance between the fill and non-ground copper, and the larger 40 mil clearance between the fill and GND pads.One of the many products updated last night as part of the Creative Cloud was a new version of Edge Reflow. The brown-yellow color is the combination of red (top side) and green (bottom side) copper fills. You should see something like the image below. Then, you can run the DRC tool (Ladybug Checkmark in the top toolbar) which will fill all your zones. The button below that will hide the fills. To see the copper fills in your design, click on the “Show filled areas in zones” button, the 10th button in the left-size toolbar. This brings up the zone properties box for the new zone, so select the other copper layer and press “OK”. To add the fill on the other side, the easiest way is to right-click on the existing board edge, select “Zone outline”, then go to “Zones”->”Duplicate Zone”. Generally you want to have a copper fill on both the top and bottom of the PCB. You should see red or green hatching (depending on which copper layer you used) on the edges of your PCB indicating the filled region, as shown in the image below. Then, to complete the final segment, double-click on the original corner to end the zone. Once you have closed the zone properties window, click once in each of the other three corners (in order) on the board outline. Click “OK” to close this window and continue drawing the fill outline. You also want to select “Arbitrary” for the “Outline Slope” setting to make it easier to draw the zone outline. We’ve found these settings to work pretty well for most of our projects. The “Thermal Reliefs” settings control the clearance around the ground pads (0.040″ here) and the width of the traces connecting from the fill to the ground pads (0.009″ here). The “Minimum width” setting controls the thinnest that the fill can be when flowing around other pads/traces. The “Clearance” setting controls the general clearance between the filled area and pads/traces of other nets. This still provides a very good electrical connection for the ground pad, but makes it much easier to solder. To avoid this problem, you almost always want to add “thermal relief” to your ground pads, which means there is a keep-out area adjacent to each ground pad where there is no fill, and instead each ground pad is connected by a number of thinner traces. ![]() One potential problem with adding ground fill is that the ground pads will become very difficult to solder, as the ground plane will suck away all the heat from your soldering iron, and the pad won’t ever heat up hot enough for the solder to flow. The settings in the bottom half are important for controlling the drawing of the filled area as well as the “thermals”. Select the relevant copper layer (here, either “F.Cu” or “B.Cu”) and the desired net for the fill (usually you want “GND”, but sometimes you might want some other net, or “” which will make an isolated copper fill). Once you click in the first corner, the following properties box will appear. Next, click in one corner of the PCB outline to start drawing the copper fill. Then, select the “Add Filled Zones†from the toolbar on the right side of the screen. First, ensure that you have selected one of the copper layers (such as “Front†or “F.Cuâ€). We usually add fills after having already drawn in the PCB outline in the Edges layer. It is relatively easy to create a copper fill in Kicad. This has a number of advantages, including decreasing the amount of etching fluid required during manufacturing, as well as reducing the amount of electrical noise and signal crosstalk experienced by the circuit elements. #Edge reflow tutorials software#This is part of a series of short tutorials on advanced topics of using Kicad, the favorite schematic/PCB design software here at Wayne and Layne.Ī copper pour or fill refers to an area on a printed circuit board where the original copper is not etched away, and remains in place, usually electrically connected to the Ground signal, producing a “Ground Plane”. ![]()
