PCB Roller Coater
This roller coater is for in-line application of coatings and protective sealants to the top surface of printed circuit boards as they travel down a production or assembly line. The coater has both infeed and outfeed conveyor sections which match the pass line height of the main conveyor line, and are synchronized to the line speed.
In the Model C Single Top Coater Roll Configuration, the liquid coating for the top surface is held in the trough between the top coating roller and its companion doctor roll; the bottom roller simply assists in feeding the substrate through the machine.
Folks call this a roller coater, a roll coater, a coating applicator, PCB surface sealant applicator, in-line coater, or a line-synchronized roller coater.
The Union PCB Roller Coater is specifically designed and constructed to apply protective coatings (Sealbrite) to the top surface of printed circuit boards. Several special features were incorporated into a Union Series #5, Model C, 26" Roller Coater to allow the machine to perform the critical application of an accurate and consistent coating. An infeed and offbearing conveyor permits the Roller Coater to be placed directly in a production line. The conveyor is powered by the same motor that powers the rolls, so line speeds are always maintained and synchronized. The machine is completely explosion-proof due to the makeup of the coating material and cleanup solvent.
