Printed circuit boardWikipedia
Printed circuit boards were introduced to reduce the size, weight, and cost of parts of the circuitry. In 1960, a small consumer radio receiver might be built with all its circuitry on one circuit board, but a TV set would probably contain one or more circuit boards.
Etching Technology Of Outer Circuit Of PCB Circuit Board
In the processing of the outer circuit of the printed circuit board, there is another method of replacing the metal plating layer with a photosensitive film as a resist layer. This method is very similar to the inner layer etching process, and can be referred to the etching in the inner layer fabrication process.
PCB etching process and process control | Andwin Circuits
Home » PCB etching process and process control . In the printed circuit board outer circuit processing technology, there is another way, is to use the photosensitive film instead of metal coating to do corrosion layer. This method is very similar to the inner layer etching process, which can be seen in the inner layer of the etching process. .
Printed Circuit Board FabricationRinse Water Quality
Both the price tag attached to each gallon of water consumed, and the cost of waste treating the rinse waters are major factors. We see therefore, that the “more is better” attitude to improving rinse water quality cannot be acceptable across the board. This brings us to the ultimate question.
