Our production profile can be useful and assist to so many. Our firm offers lots of solutions to those who are active in the professional field of printed circuits.
Excellent prices with the obvious guarantee, and not only the appropriate content is it what you would like?
MEGACO is pleased to offer you its solution: We undertake reliable manufacturing of printed circuit boards with short delivery term at acceptable prices. Whether it is one-sided, double-sided or multi-layer (up to 22 layers),we can offer to you solutions. Naturally, our offer would not be complete if we said good-bye to you at the point of production. We do not stop there, for we undertake also the installation of circuits as well as the ready-to-use assembly of same, and these things also within short term at that.
