Low price dry film application tells about the classification knowledge of dry film according to use

Dry resist film and hole mask dry film are used to manufacture printed board images, while solder mask dry film is coated on the surface of the finished printed board to selectively protect the surface of the printed board so that when components are soldered It is also a permanent protective layer on the surface of the printed board, which can prevent moisture, mildew, and salt spray.

dry film application on sales Introduce the preparation method of dry film aqueous solution

There are many formulations of aqueous dry film photosensitive adhesives, which are mainly composed of film-forming substances, photosensitive monomers, dyes (or pigments), photoinitiators, and solvents. The film-forming substance is phthalic anhydride resin, which is actually a binder, which binds the components into a film and provides the toughness of the film.

How hot melt adhesive on sales sticks fast

How hot melt adhesive on sales sticks fast

The hot melt adhesive on sales generally dries fast, it is suitable for use in summer, but if it is used in winter, the cold air will accelerate the drying speed of the glue, which may cause the speed of process application to be slower. On, there will be the so-called sticky, false sticking phenomenon.
