Elegant Keepsakes with Custom Coins  

Tokens of appreciation and medals given for honor and achievement are the usual purposes served by custom coins. When it comes to giving keepsakes for weddings, birthdays or any occasions, coins are usually overlooked. Coins that are uniquely designed to give as keepsakes will make your event more special and memorable. Here are some of the occasions that can be immortalized through custom coins.

Challenge coin

Common keepsakes or favors for weddings are bags with some sweets inside, candles, matchboxes, and shot glasses to name a few. These are cute things to give away as wedding favors but you would surely want this event to be remembered for a long time with an extra special favor for your friends and family. Your wedding is one of the most important events in your life and custom coins will make it more awesome. It can be useful for the recipient in the shape of a key chain or a lapel pin. Print a 3D image of you and your spouse or have your favorite poem or quote engraved on the coin signed with your names. Include the date and location of the event as well.


Imagine the face of your baby immortalized on a coin. That is a great way to make the event much more memorable. A personalized coin is also a great idea as a gift for the child and his or her parents. It is something that is worth keeping.

Family Reunions

While a group picture in your physical or online album will surely make a family reunion memorable, giving out coins as keepsakes will make it more of an interesting and special event. Make the shape and color of your custom coins different each year so that relatives will always look forward to attending the occasion. You can also engrave the name of a family member on each coin to make it more personal.

Easter Egg Hunting

Make children more excited in looking for those hidden eggs by having them look for those with a coin inside. The more eggs with coins they find, the higher the prize. It will surely be more fun hunting for more than just candies or any sweet goodies inside the eggs. Children will feel more adventurous in hunting with that twist in the game. If you are hosting the egg hunt, you may also want to give customized coins to all participants as tokens of appreciation for making the event a success.


This can be made more fun with coins as keepsakes. You can also have a specially made coin that will serve as a small medallion for winning a party game that you planned for the event. You can engrave the date and time and even the location on the flip side of the coin.


The silver or golden anniversary is a milestone in a couples’ life. If you are the one celebrating this event, coins are best favor you can give to mark this very special event. If you are attending one, a coin with your personal message engraved on it will be very much appreciated.

Custom coins can come in any shape that you want. You can stick with the usual rounded shape or let your imagination run wild to create odd-shaped coins that will be unique for your special occasion. You can choose from a variety of base metals that will be used as well as the colors or finishing that you want. Turn coins into bracelets for female attendees and pins or key chains for male attendees. Create the custom look and feel that you want for your coin. It’s your party and you can customize your coin any way you want.

Commons Methods Used in Creating a Printed Circuit Board Pattern

There are various ways to create a copper pattern, or mask, for a printed circuit board. The simplest method is to use a permanent marker. You can also use a silkscreen, a photoengraving method using a photoresist coating, and PCB milling. These methods are collectively known as subtractive methods of creating PCB patterns. A subtractive method will remove the copper substrate from the board and leave only the desired PCB pattern. This pattern is based on the circuit’s schematic design.

Here are the definitions for each method:

Silkscreen Printing

Silkscreen printing uses a special ink that is designed to resist the etching solution. The paint, or ink, masks specific portions of the printed circuit board, and protects the copper foil from being eaten away by the acid. All the exposed copper will then be removed by the etching process.

A woven mesh is needed in order to create a silkscreen. The desired pattern is cured and developed into the mesh, forming an ink-blocking stencil. The mesh will then be divided into ink-blocked areas and open areas. The open areas of the mesh will contain the copper connections and the vias (circular copper area that will be drilled). Inks can be transferred to these areas. You just put the silkscreen on top of the PCB, and apply ink to the screen. A squeegee is used to force the ink through the mesh openings. The final product is the PCB pattern.

This method is used in mass production. The silk screen is used to print one PCB layout pattern to multiple copper boards in the shortest possible amount of time.

Photoengraving Process

Printed circuit boardA photoengraving process consists of a special-purpose printed circuit board called a photoresist, a photomask and a developer. This type of PCB is sensitive to light. This process uses a photomask and a developer. A photomask marks a portion of the copper that will be exempted from etching. A developer will then be used to remove the exposed areas of the photomask coating.

A photomask is a plastic film (example: over-head projector film) that contains the printout of a PCB layout. A photoresist has a thick cover that protects it from light. This cover must not be peeled off before the exposure process begins. This process involves the exposure of the photoresist to bright light. The protected areas (copper that should not be eaten by the acid), however, should be covered with the photomask.

Put the light source on top, the photomask at the middle, and the photoresist PCB at the bottom. The photomask and PCB must also be tightly pressed together. The exposure will depend on the intensity of the light source. After some time, remove the board from the light.

The developer is a powdered chemical that is mixed on water. The solution will dissolve the portion of the mask that was left exposed. The PCB must be submerged to a container that contains the developer solution. Shake the basin until an image appears. The image, usually of blue color, is the developed printed circuit board pattern. The part exposed to the light source contains bare copper.

This method is used by hobbyists and small businesses. It is still better to use this method, than using a permanent marker as a mask.

PCB Milling

PCB milling does not create a mask. It uses a machine that physically removes the copper by drilling on the PCB itself. It is effectively the etched board itself. The miller usually is a two or three-axis mechanical drill. This machine operates like a plotter. It receives commands from a computer software, which controls the driller’s position in the x, y, and, if possible, the z axis. The data is retrieved as a file. This method is commonly used with computer-aided machinery. It is only used by large industries, since only few people or businesses can afford this machine and its corresponding software.


There are various ways to create a printed circuit board pattern. Your chosen method may vary, depending on your objectives. Having a good mask can save you problems in etching.
