How to make a PCB using Marker

Home made PCB Etching using Marker How to make a pcb An easily understandable video demonstration of how to make PCBs at home with available inexpensive materials. This process involves the use of a chemical etchant called Ferric Chloride. It is to be treated with the utmost respect and care. This means that it has to be handled with caution and disposed of properly. Ferric Chloride is an etchant.

DO NOT pour down the sink or flush down the toilet. LET’S BEGIN First we will want to assemble our tools and chemilcals. Here is a small shopping list: Ferric Chloride/etchant - this will remove unwanted copper from the board. Copper clad - this is the term for the unetched board that will eventually be your circuit. Copper clad comes in varying thicknesses and can be one or two sided. Acetone - we will use this to prime the unetched board. Lacquer solvent - this is for one of the final stages of the process where in we remove the resist. Glossy pages from a magazine or Staples photo paper for inkjet printers. Steel Wool - for preparing the copper. Toothbrush - for cleaning the paper from the board before etching. Several plastic containers - these containers should be larger than the board you are etching. I use three: two for soapy water and one for the etchant. Iron or Heat Press - this is used to apply the resist to the copper clad. Access to a laser printer. Now that everything is assembled it’s time to design your circuit in our favorite program. This can be anything from eagle PCB to Illustrator. As long as you can print the design, it’s all good. You can print on Staples photo paper. Try to find the cheapest available, but feel free to experiment with all kinds. Lately it seems that glossy pages from a magazine work better than If possible, run the paper through the printer twice to double up on the print. This can be tricky because the paper doesn’t always move through the printer the same way twice. I found that putting the paper in the same corner of the paper tray helped. In many cases there was little or no doubling of the design. Here is what’s happening: laser toner contains plastic fibers. These fibers are what we call the resist as it resists the ferric chloride in the etching process. Being plastic, they are sensitive to heat, which will come in handy when we apply the design to the copper clad. Prep the board. Before applying our design, it’s important to prep the copper clad. Take the steel wool and rub down the copper until it has a well brushed look. This puts little grooves in the copper and creates a greater surface area for the resist to attach to and the ferrich chloride to react with. After the steel wool, clean the board with the acetone. It will pick up all the fine copper dust created by the steel wool. Though it’s just dust, it will save on the ferric chloride. There’s no sense in the chemical eatiing away material that’s not on the board.Once the board is clean use the iron or heat press to apply the design to the copper clad. Take the second plastic container and pour enough ferric chloride in to completely submerge the board.If the container has a lid, put it on and gently rock the container to agitate the etchant. If you have no lid, then find a piece of plastic to use as a stirring stick and move the ferric chloride with this. After ten minutes has passed check the copper clad for progress. There should be patches where the copper has been completely etched away.he ferric chloride will turn completely black and the design will be all that remain. continue to agitate the chemical until only the design is on the board. Once the unwanted copper is completely removed, use the tongs to move the board from the etchant and into the last container of soapy water for rinsing.When the last of the etchant is removed from the board, take the laquer thinner and with a cloth remove the resist until your design in copper is revealed. Drill the holes for your components and you have made your first circuitboard. Congratulations! You’ve just etched your first printed circuit board.
