Optical imaging solder resist ink is an important consumable for PCB manufacturing, and local companies’ market share continues to increase

Solder mask ink is one of the most commonly used printing materials for printed circuit boards. It refers to the ink that is coated on printed circuit boards to protect circuits and substrates. Photo-imaging solder mask ink is a subdivision product of solder mask ink, also known as photo-imaging solder mask ink, which refers to UV ink used to manufacture double-sided or multi-layer board solder mask patterns. Photo-imaging solder mask ink has the advantages of good corrosion resistance, fast photosensitivity, high resolution, and resistance to electroplating, and has broad application prospects in the electronic and electrical fields.

Photoimaging solder mask ink is a liquid two-component ink, which is usually composed of photoinitiator, reactive diluent, thermosetting epoxy resin, alkali-soluble photocurable resin, curing agent, filler, pigment, additives and other materials. Among them, thermosetting Epoxy resin and alkali-soluble light-curing resin account for the main production costs. Thermosetting epoxy resin contains epoxy groups and heat-curing components, which play an important role in the developability of photo-imaging solder mask inks. Alkali-soluble photo-curable resin needs to have high sensitivity and high resolution capabilities, and is the main material of photo-imaging solder mask.

The main coating methods of photo-imaging solder mask ink include spray coating, screen printing, curtain coating, etc. The screen printing method refers to using the screen as the plate material, coating a layer of photo-imaging solder mask ink on its surface, and allowing the ink to pass through the screen and print on the double-sided or multi-layer board, thereby realizing the pattern transfer. This method has The equipment has the advantages of simple operation and low operating cost, and is widely used in our country.
