=== Pros/Cons === | |||
Pros: | |||
* Quite Faster than manual UV-exposing, etching and drilling. | |||
* Cool | |||
* No chemicals | |||
* Good for high currents, as wired are wide. | |||
* Cheaper PCB material. (Same area approx 50% the price) | |||
* PCBs of up to 30x20 cm. However, flatness is problematic. | |||
Cons: | |||
* If the board is not mounted completely flat, the isolation might be not deep enough, and hence there are short circuits. | |||
* Sometimes, flakes of copper short circuit neighboring copper areas. Usually at corners. A knife helps. | |||
* Dust. | |||
* Loud. | |||
* Capacity between adjacent copper areas. | |||
* Hotter soldering is required, as there are no thermal pads. | |||
* 0805 SMD resistors work fine, although the solder locations are not visible any more. However, SMD chips are probably to small | |||
