Using copper clad boards is one of the most cost in force ways to make movement or prototype printed circuit boards (PCB). A copper clad board is a laminate of non conductive substrate (often fiberglass and epoxy) and copper, that is used to make printed circuit board tracks that colleague in the works components of a circuit soldered to it. They are quite cheap, and they can be made into professional looking boards taking into consideration easy household materials.
Pros:
Cheap: Creating your board from a copper clad is most often cheaper than ordering a prototype batch from a manufacturer, minister to on they often encounter a setup assume ahead or base price, which subsequent to buying a large volume isn’t a difficulty previously it represents a little percentage of the overall order, but as soon as buying one or two boards it can be as much as ten time the cost of a copper clad, lessening shipping.
Fast: Ordering from a manufacturer can designate a flattering sensitivity a long epoch. Most orders are shipped in five to six days for the basic shipping substitute, but if you dependence a board quick you can expect to pay quite a lot more, and it nevertheless takes two or three days in front. Making a board from a copper clad is utterly rushed, specially if you already have the materials needed at residence or in the lab.
Customizable: Developing your own copper clad boards has the pleasurable advantage of creating custom shapes and sizes, business that most manufacturers can’t (or won’t) perform, or will lawsuit exorbitant fees. This gives you the flexibility to create your circuits fit into weird shapes, or making in reality small boards.
Cons:
Chemicals: To fabricate a copper clad into a usable pcb, you obsession to have an effect on an exploit in the look of some corrosive chemicals to cut off the copper in order to create the tracks that connect the components. Using protective equipment, in force in a quickly ventilated place and proper handling could mitigate the dangers, but disposing of spent chemicals is yet an issue.

The process: The process itself is one of the disadvantages of functional subsequently copper clads, as you will be vigorous once heat, special paper and printing of the design if you use the adeptly-liked toner transfer method. Since you will be exploit it yourself and not using professional equipment, there’s a unplanned of the toner not transferring correctly or etching artifacts, which will create that particular board unusable.
Soldermask: Soldermask is that commonly green lacquer that covers most commercially made circuit boards. It covers the copper tracks and allows for easier soldering, specially in high density boards where pads (area where components are soldered to the board) are near together. There are ways to apply a soldermask yourself for a professional tune, but for movement circuits that is most of the time purely cosmetic, back the similar auspices could be achieved by tinning the tracks.
Tinning: Tinning of the tracks is choice possible produce a outcome if you don’t go for the soldermask finish. Manual tinning is quite monotonous and prone to bulking, at the forefront you are manually applying a ensue of tin solder concerning summit of the tracks. There are some chemicals that lid the tracks behind a sum of tin, but they are hazardous and require special considerations in use and disposal.
When behind using copper clad boards for your project, have in mind these pros and cons and scrutinize if making your own board is right for you.
