Viscosity measurements in the coating process of printed circuit boards (pcb)

The dosage of a printed circuit board coating solution requires fine tuning to achieve uniformity of coating application. A constant viscosity reflects that uniformity. An inhomogeneous coating, or too thick or thin a coating in the production of printed circuit boards, can cause serious problems. A company's reputation is at stake when there are too many complaints from customers due to poor quality of the final product. As a result, costs rise due to inefficient production and raw material losses.

By installing a MIVI process viscometer in the circulation loop of the coating process, the right amount of solvent can be injected into the base resin at the right time during the entire production process.

The MIVI viscometer works continuously and immediately detects and corrects any viscosity variation.
