Make your own PCBs at home is an economical alternative to an order from one of many PCB manufacturers. Using simple household items you can get your home pcb etching station to start creating your own custom PCB.
Before beginning to put together your etching station, make sure you understand the process and want to use the material as a solution to treat an acid etching process. Be sure to take specialattention in the development of your style, such as gloves, eye protection and work in a well ventilated area.
The materials needed to affect your job is easy to have someone who can have at home. Since we use the toner transfer method, you need a laser printer to print your designs, so you can wear to the board.
To transfer actual design, printing on photo paper or other high brightness asmagazine paper, it is because we have the toner printed by laser printers to Remain on the paper surface of Com toner will adhere to the paper fibers in a plain and transfers will not be reliable. Another thing to consider is that a print reverse or mirror image of your design, so when you wear it, and traces of letters have the correct orientation.
Now that you have your design, it is time to transfer to the vacuumcircuit, also called copper clad board. These cards have a laminate of copper on a non-conductive surfaces such as glass fiber epoxy FR4 of the Common Council. These dishes are easy to obtain as many hobbies and electronics stores have them or you can even go online.
Make sure the copper surface to it so well that the area of oil or oxide forms before the transfer of toner can not be broken stick and must be removed leaving a trace.
To transfer, you must enterglossy paper with the design side print buyers laminated and then printed with a steam iron without higher taxes. Use the general pressure of iron over the entire surface of the table to apply a bit, 'use the pressure point located in the areas of the board to ensure that fuses the toner to use and quick for buyers. Corners and areas with high density design requires special attention in this heat and pressure steps.
The transfer is now set atcopper, paper removed, soak the board in hot soapy water and peel the paper when wet, but make sure not too much pressure or toner can also make use.
The last step is really the board, so the tracks do. There are two general acids, which can be used is the ferric chloride, available at most electronics stores, the other by means of hydrochloric acid and hydrogen peroxide. The formulas and methods used for acids, etc. is an art and sciencethem, and is outside the scope of the article. This is typically the positioning of the plate in acid and wait for the buyer may face dissolved in acid.
After the procedure, etc., it is time for the Board of toner to clean, so there may be a coating or tinning Soldermask cuts for protection against corrosion of use. Drill holes may be necessary if you have used through hole components.
Now you know how to make your own printed circuit boards to do at home. This processgives you the flexibility to work not only with a design of low volume and low-cost materials, but also your printed circuit board to create a number of shapes other than rectangular or square, which would cost a fortune in trade published.
