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

Do you know what the dry film is classified by use? Follow the Low price dry film application editor for a brief understanding of it!

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. In order to adapt to the alkaline gold plating and cyanide gold plating of printed plugs, there is also a dry film that is resistant to gold plating solutions called "light strips". The initial production is mainly anti-corrosion and anti-plating products, which are used to make anti-corrosion dry films for circuit patterns. In order to meet the needs of welding and protection, solder mask dry film appeared later. Due to the high cost of solder resist dry film and the need for expensive vacuum lamination equipment in the application, it was replaced by the rapidly developing liquid photosensitive solder resist.
The above is the description of the Low price dry film application: a brief introduction to the classification knowledge of dry film according to its purpose.
