Application specific dosingof pastes and adhesives
Accurate, repeatable and uniform
A core competence of acp systems AG is the process of micro-dispensing. One application in the photovoltaic sector, is the process of dispensing silver conductive adhesives onto glass substrates to create the electrical busbar in the manufacture of solar modules.
In this application, the challenge is to provide an accurate, flat and uniform adhesive line, resulting in an even and uniform conductive bond to the substrate.
To achieve this, and working closely with the industry sector, a special purpose micro-dispending valve was developed to achieve precise dosing of solder pastes, viscous sealant, and other materials enriched with solid particles.
The target is to meet the three level criteria of time, pressure and dosing quantity to lay an accurate, repeatable line thickness of materials containing metallic particles.
