The invention provides a PCB (printed circuit board) etching method and a work-in-process PCB. The method includes: covering an anti-etching dry film on a gold layer of the PCB and then etching. The gold layer is covered on the metal layer on the surface of the work-in-process PCB, ...
When you remove every bit of unwanted copper from the PCB, the alkaline process hits a point known as the breakpoint. At this point, no more etching is supposed to take place. The breakpoint is, in most cases, reached when the PCB is at the spray chamber’s midpoint. For example, i...
PCB Etching (prototyping): Making circuits is great but what if you want to make your ideas a bit more permanent? That´s when it´s great to be able to make your own PCBs at home. I´ll show you how to make your own single sided Printed Circuit Bo

etchant and place it in the microwave for 5-10 seconds. I then place the container of etchant on my etching rig and dip the copper clad PCB in. You do not need a rig to do this, just use your hand to rock back and forth (agitate) the chemical to speed up the etching process....
In this case, I knew I was going to need several dozen boards for testing. To save time, I chose to use my table saw to cut apart a large PCB panel. Regardless of how you cut your boards, you must remove any copper burrs from the edges. The burrs are unsightly, can cut you, ...
