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, ...
Anyone who has ever etched their own PCB knows that the waiting is the hardest part. Dissolving copper in ferric chloride takes time, much like developing a Polaroid picture. And although you really should not shake a fresh Polaroid to speed up development, the PCB etching process thrives on ...
Using a permanent marker, draw to traces between all the components referencing the printed PCB layout. Allow some time for the ink to dry and touch up the board where the marker is faint. Step 4: The Etching Process Once the second coat of marker is completely dry it is time to give ...

1.Mix the developer following the description on its package. I´ve never tried it myself but 10g of NaOH in 1 litre of water should work as well. 2.Put your PCB into the developer solution immediately after finishing the process of exposing. ...
Copper Etching is an important step in the PCB production process. During copper etching,the cuprous ion concentration in the etchant would increase which causes an etching rate reduction. In this study,a boron doped diamond electrode (BDD) is used as anode to generate hydroxyl free radicals whi...
