Improve a filter method for copper ashes consent copper filtration unit, comprise the following steps:
Step one, the heavy copper liquid medicine that the filtration unit comprising filter bag on support and fixed support carries out changing in copper cylinder filters;
Step 2, heavy copper liquid medicine carries out chemical reaction and produces the impurity such as shot copper, copper ashes;
Step 3, filters the impurity such as shot copper, copper ashes that chemical reaction in step 2 produces;
Step 4, PCB product is purified, and quality defect is not obvious.
Preferably, the inside of describedization copper cylinder is provided with heavy copper liquid medicine.
Preferably, described carrier pipe, discharge nozzle and feed-pipe only adopt PE plastic material.
Preferably, the surface of describedization copper cylinder is provided with corrosion-resistant coating.
In the present invention, filtration unit is installed in the secondary slot of heavy drawing of copper copper cylinder, filtration unit comprises filter bag on support and fixed support, by filtration unit, the heavy copper liquid medicine changed in copper is filtered, by the shot copper produced by chemical reaction in heavy copper liquid medicine, the contaminant filters such as copper ashes are clean, it is prevented to be attached on PCB product, cause quality defect, after using this filtration unit, make the shot copper of product, the bad ratio of copper ashes consent declines obviously, 3% is dropped to by 15%, product shot copper, copper ashes condemnation factor reduces by 1%, improve the qualification rate of product, ensure that the quality of product, the make efficiency of the PCB improved.
Accompanying drawing explanation
