Operating parameters:
1. Open oil
After the ink is fully mixed to the mixing,stirring after the static 15min above,so that the ink viscosity stability in the use of ink use do not need to add a diluent,such as viscosity is too large,can be used as a special diluent debugging,but the amount can not be added more than 5%.(in order to make good adhesion to the substrate,the cleaning operation is preferred)
2. Screen printing
Screen printing:take 100-120T nylon diagonal net tension,23+1N
Rubber scraper scraping:65 degrees-75 degrees of good elasticity,sharp edges,squeegee angle of 5-20 degrees,2-6kg/cm-pressure
3. UV curing
Energy:800-1500mj/cm
Note:according to the different equipment,conveyor belt speed and energt have a greater difference,but should be completely cured ink is appropriate.
Matters needing attention:
This specification in all parameters and results for the company's test data,can only be done for early reference,as a guarantee and basis,pratical application to customers for the field test conditions and test results.
Our company:
Hubei Nuojinsen Technology Co.,Ltd ,after years of unremitting efforts,Combined with foreign advanced technology and process,Production of PCB ink has reached the technical level, conforms to the requirement of RoHS environmental protection directive, with excellent quality and excellent service is deeply trusted by customers.
