This paper presents a prediction model of the adhesive coating thickness on a space solar cell. The model describes the non-Newtonian characteristics of the adhesive when it is bonded to the cover glass and the space solar cell in a non-vacuumed environment. The coating thickness is a function of the differential pressure inside the syringe and its relative speed. It can be indirectly controlled by the two feedbacks. Compared with other systems, the automatic one has better effect on the manufacture of the qualified space solar cell array.
