The Origin and Development of Traditional PCB Inks

The Origin and Development of Traditional PCB Inks

The origins of traditional PCB inks can be traced back to the mid-20th century, when the rapid development of electronic devices—particularly the widespread adoption of products such as televisions and tape recorders—led to a sharp increase in demand for circuit boards. In the early days, circuit board manufacturing relied primarily on colloidal masks using dichromate salts as photosensitive agents. However, these masks had several drawbacks, including cumbersome handling, high cost, and a tendency to catch fire, making them unsafe. As a result, people began exploring new mask materials and technologies.
