Embodiment 1
[0047] The method for making printed circuit board of the present invention comprises the steps:
[0048] (1) Preparation of printing solution
[0049] a) under normal temperature and pressure, respectively add calixarene and organic solvent into a container with a stirring device, and continue stirring for 5 minutes to obtain a calixarene solution, and the mass percentage of calixarene in the solution is 1%;
[0050] b) Under normal temperature and pressure, add the liquid copper slurry and the calixarene solution obtained in step a into a container with a dispersing device, and continue to disperse for 10 minutes at a speed of 400 rpm, and then discharge the material to obtain a printing solution. The mass ratio of copper particles to calixarene in the primary printing solution is 2:1;
[0051] (2) Substrate pretreatment
[0052] c) Drill and clean the substrate according to the circuit requirements, and place the substrate on the screen printing table of the screen printi...
