Solvent dosage, a flow characteristic of the coating solution, requires precise adjustment and can be regulated.  By maintaining a constant viscosity, varnish coating uniformity is achieved. A non-homogeneous coating (excessively thick or thin), causes major issues. A company's reputation can be compromised due to customer claims regarding poor product quality, and a company’s overhead will increase due to inefficient production and losses in raw materials.

Installing a MIVI process viscometer on the coating circulation loop allows timely solvent dosage injection to the base resin throughout the entire production batch or process. Printed circuit boards (PCB) dipped in a resin base coating and solidified at room temperature raise coating uniformity and quality to 100%. Viscosity measurements reduce solvent and resin consumption.

The inline MIVI viscosity sensor provides constant varnish viscosity measurements, reduces the consumption of raw materials, and increases monetary savings regarding time and overhead. Given the expensive nature of a single PCB, a rejected batch, operators' overtime, and consequent production downtime equal enormous losses.
