| titleOfInvention | A kind of preparation method of liquid photocurable solder mask and its photosensitive resin |
| abstract | The invention discloses the preparation methods of a kind of liquid photocurable solder mask and its photosensitive resin, belong to printed wiring board solder mask technical field.Photosensitive resin in the solder mask is to carry out ring-opening reaction first with acrylic acid and epoxy resin to obtain intermediate product epoxy acrylate, and the epoxy acrylate carries out the carboxylated modified epoxy acrylic ester resin that ring-opening reaction obtains with acid anhydrides again；The epoxy resin for carrying out ring-opening reaction with acrylic acid is selected from least one of E12, E12A, E13, E14, ECN268, ECN273, ECN280.Since the modified epoxy acrylic ester resin of the carboxylated has good photocuring ability and suitable diluted alkaline water solvability, therefore the liquid photocurable solder mask resolution with higher using the carboxylated modified epoxy acrylic ester resin as photosensitive resin, can parse 40 μm of routes below.In addition, solder mask of the invention also has to the good adhesion strength of substrate, good antiacid, alkali resistant and anti-solvent ability. |
