How to create through hole footprint altium

How do you make a hole in your footprint in Altium?

We can create mounting holes in Altium Designer in two ways. Create a mounting hole as a common object using Place > Pad from the main menus. After creating a pad, we need to configure its type (through), the exact size of the hole, the metallization area, and manually assign a net to it.

How do you make a through in Altium?

Right-click in the design space then choose the Place » Via command from the context menu.

How do I create a custom footprint in Altium?

  1. Step 1: Create the Pads.
  2. Step 2: Define Component Height and Area.
  3. Step 3: Add Silk Screen Information.
  4. Step 4: Save the Footprint.

How do you make a non plated hole in Altium?

right click on the hole. select properties. unselect "plated".

How do you make a hole in a PCB?

The hole can be created either through electrochemical etching (chemical milling) or by mechanical means such as drilling, laser cutting, or punching. The most common method used in manufacturing today is the combination of chemical milling and electrochemical etching.

How do I edit a drill table in Altium?

The drill table is automatically sized based on the specified Text Height setting, as well as the number of different hole sizes (rows) and the number of defined columns. To interactively resize the table, click once to select it then click and hold on a corner vertex then move to resize as required.

How do you create a footprint from a Datasheet?

  1. Specify the appropriate name for the part.
  2. Create your logical symbol using pin tables and diagrams.
  3. Create the physical footprint using mechanical dimensions.
  4. You have found the appropriate name, entered the symbol information (creating a graphical representation)

How do I add footprints to schematic Altium?

Footprints can be added to schematic components using the Properties Panel. Selecting the schematic component, under the Parameters section, click the Add button and select Footprint.

What is mounting hole in PCB?

Mounting holes seem simple enough—they let you mount your PCB to an enclosure or a surface. Simply pick a screw size that makes sense for the size of your board and the surface you wish to mount it to, and drill accordingly.

Should PCB mounting holes be grounded?

Mounting holes should generally be plated as this allows mounting with metal screws. Because floating bits of metal can be sources of EMI, the mounting holes should be connected to some ground net (earth (PE), signal ground (SGND), a grounded enclosure, etc.).

What size are mounting holes on PCB?

Although there is no fixed hole size that must be used, there is a definable range of standard PCB drill hole sizes to guide your selection. By choosing a hole size between 5 mil (0.13 mm) to 20 mil (0.51 mm), your CM should be able to accommodate your design, although the smaller sizes may cost more.

Can you drill a hole through a PCB?

PCB construction is certainly an area where drilling is a critical part of the process. This is true whether your design is single-layer and only needs mounting holes or is a multilayer PCB that requires vias. In most cases, your design requires both of these, as well as other types of drill holes.

Can you drill through a PCB?

Single-sided or double-sided PCB will be drilled directly after getting on the production line. Multi-layer board will be drilled after pressuring layers. By classification of the function, different drilling holes can be divided: parts hole, tool hole, through the hole, blind hole, Buried hole.

Why do you drill holes in PCB?

PCB tool holes help to keep the board aligned and still during a specific operation. For instance, the board must not move laterally when drilling to achieve proper drilling accuracy. Similarly, the operator locks the board in place with the tool holes when using a stencil to deposit solder paste on the board.

How do you add drill drawings in Altium?

  1. Choose the Place » Additional Views » Board Drill Drawing View command from the main menus.
  2. Click the button in the view objects drop-down on the Active Bar located at the top of the workspace.

How do you make a drill file in Altium?

How to Generate NC Drill File by Altium Designer? In the main interface of Altium Designer, click File>>Fabrication Outputs>>NC Drill Files sequently and come to NC Drill Setup dialogue in which options need to be specified including NC Drill Format, Leading/Trailing Zeroes, Coordinate Positions etc.

What is via tenting?

Tenting a via refers to covering via with soldermask to enclose or skin over the opening. A via is a hole drilled into the PCB that allows multiple layers on the PCB to be connected to each other. A non-tented via is just a via that is not covered with the soldermask layer.

Should vias be tented?

Tenting is best used on small vias with a finished hole diameter of less than about 12 mil. The specific diameter limit depends on the LPI solder mask solution, and your fabricator should be able to recommend a maximum via diameter to ensure reliable tenting.

What are stitching vias?

Via stitching is a technique used to tie together larger copper areas on different layers, in effect creating a strong vertical connection through the board structure, helping maintain a low impedance and short return loops.

How do you use blind vias?

Blind vias are used to connect one outer layer with at least one inner layer. The holes for each connection level must be defined as a separate drill file. The ratio of drill diameter to hole depth (aspect ratio) must be 1:1 or larger. outer layer and the corresponding inner layers.

How to create through hole footprint altium

Comment by Dale Godbout

hello in this video we're going to have a look at how to make a new library for Altium and how to generate a new footprint and schematic for a library component we're then going to show how we would integrate it with the circuit that we built in the first tutorial so we are going to start by clicking on our projects over on the left hand side right clicking choosing add new to project and then a schematic library we can actually make the PCB library first if we want it doesn't matter which order you create these documents in so let's start with the PCB library instead the PCB library generation window looks very similar to the window we use to design these circuit boards last week we had a look at designing this circuit here and you can see it's a very similar layout the first thing that we're going to do is have a look over here on the left hand side we can see there is a new PCB component which has been manufactured for us we can double click this if we want and rename it so why don't we call it 505 timer and this is going to be a dip package dual inline package what that means is that our component has legs like this it's a dual inline so two lines description 505 will probably do my remove this up here as well 5:55 dip about the name and description we can ignore the height property for the moment but so the first thing you'll notice is we have an origin on the center of the screen as I move my mouse around you will see that we have an X and a Y in the top left hand corner of the screen up here and as I go to here we have 0 0 the DX and dy values also change this is going to be a moving number so if I hover over this 0 0 point and press the insert key you'll see it resets the DX and dy this is good because we want it to be something that moves around as we move the mouse starting at the origin point so the first thing I'm going to do is save this library because we haven't saved it yet I have got one here already PCB Lib one let's call this 5 5 5 Lib safe so the first thing we're going to need to do is add a pad we can do that either by clicking the pad button up here by right clicking and choosing place pad or by simply using the key command PP this adds a pad to the mouse before we click anywhere we're going to want to press the tab key to open up this window we'll remember whenever we're doing anything out in before we click on place we can press the tab to access the properties this is going to be a multi layer pad that means I'll have a pad on the top a hole through to the bottom layer and then a pad on the bottom layer as well the default sizes and shapes are probably going to be fine for us because then these are default for most pads there'll be no problems here what we do need to change is the designator when we look at our document we can see that we have pins 1 2 3 4 5 6 7 & 8 working in a kind of anti-clockwise motion around this pin so the first pin is one we're going to need to make sure that our designator is set to one this will make sure it's the first in so designator 1 we can press ok and you'll see it's now attached to the mouse remember if I try and move around it will scroll the page in the direction I'm moving kind of helpful but we want to make sure we're locating straight onto this pin so what I'm going to do is i'm going to click move my mouse away you'll see there is another pad attached now what I could do at this point is continue to move my mouse along and wait until I get to the right position which would be 100 mil and then click again and then there's my mouse along again and click again but we run the risk of there being error all things being slightly out of line so this isn't the best way to do this I'm gonna hit escape and I'm going to delete this last pad that I placed making sure I've only got one pad here now the order that we do these next steps is quite important what we're going to try and do is make an array of pins 1 2 3 and 4 automatically so we need to know the distance between these pins we can look up in our datasheet and see that the distance is this constant e here by comparing that in our table the small e we can see they're inches this is zero point 100 that means 100 mil not 100 millimeters 100 mil it's an imperial measurement I can click this pin pad choose right click copy and then set the origin so we click again in the center of this pad very important we do that now we can then delete the pad I know it seems strange to delete something we've just copied but bear with me we can then edit paste special uncheck paste on current layer if it is checked paste array and we're going to say we want to base for pins with an increment of 1 so 1 2 3 and 4 and we want our spacing to be 100 mil in a linear fashion we don't want any Y spacing because we just want a horizontal array that's ok and I'm going to click back on this origin point turn our four pins very useful we can continue on in the same vein to add the next pin so what we're going to do is we're going to click on the pin four right click and copy click on the origin of pin 4 but this time we're not going to delete pin 4 because we want it to remain where it is we're going to edit paste special make sure this is unchecked paste array item count for incrementing it 1 it'll start automatically on 5 because the pin we have highlighted is 4 but this time we want a minus 100 mil spacing now the question is why do we want - 100 because we can see that we've got 1 through 4 on the bottom but 5 through 8 going the opposite direction so you don't want to continue 5 6 7 8 in this direction we want to do 5 6 7 8 left we also need to check the distance here between 4 and 5 how far should these pins be away from each other so there are a couple of different things we can check here let's look at the constant F to begin with so f is showing 260 which would be the width of this package that looks about right we would also look at the constant e which is going to show a minimum of zero point three one three and a maximum of zero point three eight four we can also look for efore which is the width at the top this is going to show zero point three because this is showing a minimum of zero point three and a maximum of zero point three eight four we should probably do something in the middle I would suggest something like zero point three five so 350 we'll head back into out him click ok and we need to make sure we can see that our origin is set to 0-0 the DX and dy in the top right hand corner left hand corner is set to 0-0 so we're going to need to make sure that we go up by 350 there we go 350 I'm gonna click once and we can see the pads have been added automatically now it seems there's been a slight error here because pins four five six and seven have been named four five six and seven respectively this is a bit of a shame but nothing that we can't fix straight I'm gonna right-click and escape double click on this pin and simply change the name five six seven and eight there we go problem solved the last thing we're gonna do is add a little bit of the drawing so I'm going to choose the top overlay the line tool and I'm simply going t
