The invention provides circuit board manufacturing equipment, a turbid liquid concentration sampling analysis device and a turbid liquid concentration sampling analysis method. The turbid liquid concentration sampling analysis device comprises a sandblasting stirring tank, a sprinkling pump and a concentration measuring instrument, wherein the sandblasting stirring tank is connected with an inletof the sprinkling pump and the concentration measuring instrument through a circuit respectively so as to form two paths for turbid liquid to flow; the concentration measuring instrument comprises a measuring instrument body and a test liquid pipe arranged at one end of the measuring instrument body; the test liquid pipe is connected with the circuit so as to form a path for the turbid liquid to flow; a test liquid valve is arranged on the test liquid pipe; scales are arranged on the measuring instrument body. Through the circuit board manufacturing equipment, the turbid liquid concentration sampling analysis device and the turbid liquid concentration sampling analysis method, provided by the invention, the defects that in the prior art, the accuracy of the sampled liquid level cannot be mastered and the concentration of a sample extracted from a cylinder is different from the concentration of the sample actually sprayed onto a circuit board are effectively overcome, the accurate reliability of the sampled sample is guaranteed and the risk factor of the sampling process is also reduced.
Description
technical field [0001] The invention relates to the technical field of concentration measurement, in particular to a circuit board manufacturing device, a device and a method for sampling and analyzing the concentration of turbid liquid. Background technique [0002] With the rapid development of manufacturing technology in the printed circuit board industry, printed circuit boards (PCBs) are developing towards high-layer boards, and the requirements for product appearance quality and reliability are getting higher and higher; Before surface treatment, the copper surface of the circuit board needs to be roughened, so that the bonding force between the copper surface of the circuit board and the outer dry film, solder resist green oil, and surface treatment can achieve the best effect; at the same time, foreign matter and oxidation on the copper surface of the circuit board can be removed. Improve product appearance and reliability. [0003] Under normal circumstances, the m...
