In the process of developing the dry film of the circuit board (PCB), the product of the reaction between the dry film and sodium hydroxide or sodium bicarbonate is a surfactant, which can be adsorbed on the bubble film after being dissolved in water, thereby forming stable bubbles. 
In the development stage, the aqueous sodium carbonate solution dissolves the polymer dry film to form a foaming medium. 
With the continuous dissolution of the dry film, the developer continues to generate foam during the system's circulating spray process.
Circuit board cleaning defoamers are mainly divided into silicone defoamers, silicone-free defoamers and silicon polyether defoamers. These are defoamers specially developed for the production characteristics of circuit boards, which have better acid resistance Alkaline and excellent defoaming, anti-foaming durability.
Silicone defoamer is based on cross-linked polysiloxane as the defoaming active component, which is prepared by compound emulsification of silicon emulsifier and hydrocarbon emulsifier. Suitable for circuit board cleaning and water treatment.
Polyether defoamer is prepared by dispersing agent of polyether, organic modified polyether and polyether ester with reasonable structure. It has salt resistance, acid resistance, no oil bleaching, alkali resistance and no emulsion breaking.
Polyether defoamers are suitable for foam control in areas where  silicone defoaming cannot be used. Such as cleaning, film removal, etching, development and other processes in the production process of multilayer circuit boards.
Non-silicone defoamer is easy to disperse in water, has fast defoaming power and long-term defoaming power in a wide range of pH and temperature, especially suitable for cleaning process in chemical industry. More suitable.
When selecting the defoamer for the circuit board, in addition to considering the process recommendations, the appropriate amount of defoamer should be based on your own system.
