==Description==

The Through Hole Press is a hand-operated through hole plating machine using rivets. A rivet is a component used to easily connect traces that are transitioning between the top and bottom layers of a PCB. Specifically, it is a small hollow copper tube that can be inserted on one side of the board, then - using a specialized rivet tool like the Through Hole Press - the rivets are pressed and deformed to connect both sides. There are other methods that carry out the same function, but using rivets is the fastest and most consistent method.  {{#evu:https://www.youtube.com/watch?v=ywfjknf6Vtg}}{{#evu:https://www.youtube.com/watch?v=nz1TcfEnw-o}}

# Hole Sizing

# Hole Sizing

## Before pressing a rivet, you need to make sure you design the holes so that they fit well. For a rivet to fit nicely in a hole, the hole diameter needs to be 0.1 mm (3.9 mils) larger than the rivet outer diameter. Use the table below to see what types of rivets Voltera offers. Also, refer to the chart below to assure you have the right size rivet for the hole you are pressing it into.[[File:Through_hole_press_chart_snippet.PNG|none|thumb|500x500px]][[File:...rivetTable.png|none|thumb]]

## Additionally, these rivets are hollow, so these can also be used to secure headers on your PCB. When placing vias '''[? define term or correct word]''' in your design program, ensure the right drill size is used so the V-One '''[add to terminology]''' leaves enough space when printing the ink.

## Before pressing the rivets, you need to make sure you have the right tool inserted into the upper and lower parts of the press. These tools can be found in the drawer in front of the press. The tool you choose should have the same inside diameter of the rivet you want to press.

## Now it is time to press the rivets. Place the board over the pin of the lower tool and fit a rivet over the pin as far as possible. To flatten the other side of the rivet, press the lever until it reaches the stop pin, then release. [[File:...rivetPress.png|none|thumb]]

## Your rivet should change somewhat like this. Pressing the rivet too hard can cause it to crack and damage the traces on the board, yet pressing the rivet too softly will to a poor job because it will not make a firm connection with the traces. It should be hit just hard enough to deform the rivet to make a firm connection with the traces. With practice, you'll learn the right amount of pressure to apply. Come stop by!

# Using the Rubber Mallet

# Using the Rubber Mallet

## Rivets can also be pressed using a rubber mallet! The setup for the through hole press apply here as well. This method is faster than the Through Hole Press, but it is not as consistent.

## You will need to place all the rivets into the board. Some like to use their fingers, some like to use tweezers, it is up to you. Pinching the rivets on the side is the easiest way to go, as shown in the picture below.[[File:...rivetPlacing.png|none|thumb]]

## The through hole press pretty much just flattens down the other side on the rivet. Once all rivets have been placed, you will need to turn it upside down while keeping the rivets snug inside the hole in order to flatten the other side. Find a flat unused PCB, place it over the rivets, and turn it upside down to keep them from falling out. Using some tape to keep the plate stable on the board is something to try if things are not quite going your way.

## Using the rubber mallet and the rivet tool, you can press the rivet as shown in the picture below. Place the tip of the tool inside the rivet in an upright position, then hit the top of the tool with the mallet. The rivet tool can be found in the drawers in front of the PCB Printers.[[File:...rubberMalletPress.png|none|thumb]]
