1. Circuit board for some thin substrate (usually less than 0.8mm), due to the poor rigidity of the substrate, in the production and processing process of the substrate, may not be able to effectively remove the protective layer after special treatment to prevent copper foil oxidation on the surface of the plate, although the layer is very thin and brush is easier to remove, but it is difficult to chemical treatment, so in the circuit board production process, In the process of processing should pay Jateminɛ kɛli kunbɛnni na, a bɛ se ka a yɛrɛ tanga gɛlɛya ma min bɛ sɔrɔ nɔrɔli jugu ni fomu la plati kan, ka fara kuran foil ni kemikɛli kuran substrat kan; Ni kɔnɔna finman bɛ kɛ nɛrɛ ye, a bɛ se ka kɛ sababu ye ka nɛrɛmugu ni bulama kɛ, ka kɛ mɔgɔ ye min ɲɛ man ɲi, ka kɛ fɛn ye min tɛ kelen ye, ka nɛrɛmugu fan dɔ bɔ ani ka gɛlɛya wɛrɛw sɔrɔ.
