Abstract:
1. A method for bonding substrates, the method comprising: receiving a first substrate and a second substrate from a convey belt running at a speed being programmed via a first control means in accordance with characteristics of a material used to produce the substrates so as to ensure that first and second substrates are hardened properly; metalizing at least one of the first and second substrates; dispensing a certain amount of glue on the first substrate; pushing the first substrate and the second substrate towards each other; and applying an alternating source to generate an alternating electromagnetic field that consequently breaks down a surface tension of the glue to release air trapped in the glue; rotating the first and second substrates at a speed adapted to the characteristics of the glue to spread evenly the glue therebetween by a centrifugal force while compressing the first and second substrates for bonding under the alternating electromagnetic field, wherein said rotating the first and second substrates is controlled by a second control means in accordance with the characteristics of the glue being used; and providing at least one camera to monitor one or more of said receiving the first substrate and the second substrate from the convey belt, said metalizing at least one of the first and second substrates, and a bonding process including above said dispensing, said pushing, said applying and said rotating processes.
