Laser Marking of PCB

The PCB etching is a process of removing material from the PCB surface with the aid of an etching agent. The removal of copper areas from the PCB is called etch. The process of etching can be done by covering the parts of the laminate that are copper and then removing the copper layer.

The PCB Etching can be done at home or in the lab. A machine tool and a special cutter are used to remove a small strip of copper from the boundary of each pad and trace. The circuit elements are separated from the rest of the foil.

It is not necessarily required to heat the liquid. The ferric chloride is cheap, but it cannot be used again, and it is not friendly to the environment. It is important to dispose of it properly after use.

Ammonium persulphate is a solution used for etching circuit boards. The Ammonium persulphate is a powdery substance that requires the addition of water to make it a solution. The solution must be maintained in a hot state to ensure efficient etching of copper.

The PNP paper is a resist and a film. The paper has two sides, one shiny and one matt, which are used to transfer images onto metal. If the direction of the pattern is essential or includes lettering, it may be necessary to flip the pattern to clear the PnP paper so that it will be reversed on the PnP paper.

The Caustic Soda Solution

The Caustic Soda solution is ready for use. You can put some of it into a small bottle and the clean solution into a larger bottle for easy etch use.

Laser engraving and laser transfer

The laser-engraving through a mask and the laser-transfer method are the only methods I've tried that have been abandoned. It is highly unpredictable and very frustrating. The right mask may have worked better with laser engraving, but spray-paint left a film and didn't give great resolution.

The etching of the knife

The pivot, detent and lock face areare important to protect if you are etching a folding knife. You don't want to mess with the tolerances. You could ruin your knife by eating too much metal.

New Dura-Film Reusable Stencils

The New Dura-Film Reusable Stencils allow you to make your designs and use them over and over again different ways, without the need for re-making your stencils. You will find hundreds of ways to reuse your stencil when new ideas come up. You can make money by decorating glassware with your own designs or artwork for yourself, friends or for local restaurants, taverns or cocktail lounges.

Acid Etching

It is easy to learn but difficult to master the art of acid etching. You can create amazing works of art by burning away parts of metal. The process can be used in a variety of styles.

Printing plates, jewelry, and knife blades are popular items for acid etching. The most popular metals for metal etching are copper, brass, and nickel silver. Zinc and iron have been popular.

Daniel Hopfer etched the first acid etched image on an iron plate in 1510 It is necessary for your piece to be completely clean before it can be etched. Chemicals like oils and tarnish will affect how well the etching works.

Make sure the edges of the piece are not sharp. Make sure the surface is prepared. There are a few ways to do it.

The Shapes of Anvil

If you're new to blacksmithing, you might be wondering about the shapes that make up anvil. The physical design on anvils has been refined.
