SMW offers automated photovoltaic tabbing Machine which can interconnect solar cells by soldering metal ribbon and making strings. This machine allows 2 or 3 bus bar processing capability by optional. MEGATAB-A6023 pick and place solar cell units from magazine by vacuum pad and aligns their edges using VISION system. MEGATAB-A6023 has soldering capability by Hot air jet nozzle with hold down pins. This feature allows more control over various aspects of the soldering and increase in the solder bond consistency and quality. Our innovative spray fluxing method accurately applies just the right amount of flux for superior soldering results.

1、Cell magazing Cell stocking Process: Operator loaded the Cells into empty magazines

Cell Loading Magazine: 2 EA (STD)

Number of Magazine: 4 EA
