Electronic chemicals

Electronic chemicals:is also known as the electronic chemical materials. Generally refers to the electronics industry use of specialty chemicals and chemical materials, say: electronic components, printed circuit board, all kinds of chemicals and materials used in the packing & production of industrial and consumer product. They can be divided into following items by different applications: base board, photoresist, electroplating chemicals, encapsulating material, high purity reagents, special gas, solvents, cleaning, doping agent before cleaning, solder mask, acid and caustic, electronic special adhesives and auxiliary materials, etc. Electronic chemicals are various, high quality requirement, small dosage, high demanding of the environment cleanliness requirements, fast product upgrading, large net inflow, high value-added, etc.. Those characteristics are more and more obvious accompany with the development of the micro machining technology.

Filtration purpose: to remove particles and colloidal impurities;

Filtration requirements:
1. Due to the high viscosity filtration fluid, the filter housing is normally have to be able to withstand high pressure & mechanical strength
2. Filter material must have a good compatibility;
3. Good filtration efficiency of removing particles and colloidal impurities.

Printed circuit board yellow process technology

PCB circuit board is also called as printed circuit board, it is provider of the electrical connection in the electronic components. According to the circuit board layer, it can be divided into single panel, double panel, four layers board, 6 layers board and other multilayer circuit board.

Filtration purpose: to remove particles and colloidal impurities in the water or liquid;

Filtration requirements:
1. High flow rate, high mechanical strength, long useful life.
2. Excellent filtration efficiency.

The polishing liquid filtration procedure

CMP, means Chemical Mechanical Polishing. The equipment and consumables adopted in CMP technology including: polishing machine, polishing paste, polishing pad, after CMP cleaning equipment, polishing endpoint detection and process control equipment, waste treatment and testing equipment, etc.
CMP polishing solution is kind of high purity & low ionic metal polishing products by special process of high purity silicon powder raw material. It is widely used in various materials’ nanoscale high planarization polishing.

Filtration purpose: to remove particles and colloidal impurities;

Filtration requirements:
1. Low Soluble substance from filter media, no medium loss
2. Good ability to remove impurities, long useful life.
3. High flow rate, high mechanical strength
