. After pre-cleaning, the water is supplied to the reverse osmosis membrane, and then the water is filtered through a special deionization medium, which removes the rest of the ions in the water

? After SMT machine soldering, there will be some voids in the solder joints. These inevitable voids will cause some potential risks to the quality of the whole product, and the most direct manifestation is that the life of the product will be far less than expected

? The chemistry involved with formic acid reflow is a two-step process: During the soak phase of a thermal profile (between ~ 150C and 200C), formic acid vapor is introduced into the process chamber where it reacts with the metal oxides on the solder and creates formate salts
