412 stainless steel copper plated worm gear for consumer electronics parts.
Description
The worm gear structure is commonly used to transmit the motion and power between two interleaved shafts. The worm wheel and the worm are equivalent to the gear and the rack in the middle plane, and the worm and the screw are similar in shape.
Copper plating is usually divided into electroless copper plating
and electroplating copper.
In the PCB manufacturing industry, copper electroplating has been
used for many years. The electroplating copper solution for printed
boards is an acidic solution, which has the characteristics of high
acid and low copper, and has excellent dispersion and deep plating
capabilities. The copper layer after plating is shiny.
In the process of printed boards, copper plating has two functions:
one is full plate copper electroplating, which protects the thin
chemical copper that has just been deposited, prevents the chemical
copper from being etched away by acid after oxidation, and thickens
it to a certain extent by electroplating The thickness is usually
5gm～8gm, also called primary copper. The other is patterned copper
electroplating, which thickens the hole copper and circuit copper
to a certain thickness or serves as the bottom layer of nickel,
usually with a thickness of 20gm-25gm, which is also called
secondary copper.
Copper plating is to use steel and other parts with oil and rust
removed from the surface as the cathode, and pure copper plate as
the anode. ) Copper plating.
In order to obtain a thicker copper plating layer, the plated parts
must be alkaline copper-plated first, and then placed in an
electrolyte containing copper sulfate, nickel sulfate, and sulfuric
acid for acid copper plating. In addition, there are
pyrophosphates,
