This project guide will show you how to make your own printed circuit boards using our silkscreen stencils along with your artwork. It assumes a working knowledge of the process involved in creating the artwork and etching a printed circuit board.
The circuit pattern in this guide is intended only to demonstrate the steps required to make a printed circuit board using PhotoEZ/StencilPro silkscreen stencils.
Read all instructions before beginning your project. Read manufacture labels on products and supplies being used. Use safety glasses and gloves when using chemicals. Have FUN!
Project By: Circuit Bridge Time to Do: 3-5 hours Skill Level: Advanced
Instructions
Step 1: Gather your supplies
Step 2: Create your artwork The silkscreen stencil is a negative of your circuit design so be sure to layout and print your image as a positive non-mirrored image. For maximum detail use transparence or vellum paper when printing.
Step 3: Make your silkscreen stencil Expose and develop your film using the original artwork from step 1. Follow the instructions provided with your stencil film of choice. PhotoEZ or StencilPro will work just as well.
Step 4: Silkscreen etch resist onto your clean copper clad board Clean and prep your bare copper board as usual. In this example we used an acrylic based paint from Liquitex however any resist that is capable of being silkscreened can be used. Use the following tips to avoid bleeding and pinholes:
• Use plenty of paint.
• Keep squeegee at no lower then 45º angle. This will help prevent bleeding under the stencil.
• Use even strokes and go back and forth only once. Avoid the tendency to paint.
• Lift the stencil slowly. Lifting too fast will create bubbles and possible pinholes.
Step 5: Etch your board as usual
