Photo Chemical Machining in Bulgaria
This year we will celebrate 20 years since the beginning of PCM
in Bulgaria In the late sixties and the early seventies, the electronic
industry in Bulgaria began to develop rapidly, and, after a short
time, Bulgaria joined the list of the world’s top ten electronic
developers. Considering the flexibility, high accuracy and other
advantages of photochemical technology, it was impossible that a
rapid development of PCM for electronic needs would not
occur.
