EQUIPMENT MODEL
SS-1500B · Automatic solar cell tabber stringer
Wuhan Ooi Photoelectric Technology Co., Ltd. ↗Ooitech built the SS-1500B around automatic loading, CCD checks, robot placement and infrared soldering. Its table gives BC cells 1,000 pieces an hour and TOPCon/PERC 1,200. The product text mentions more cell types than the table covers, so ask Ooitech to confirm your cell recipe and inspection kit in writing.
One model, offered without a gluing function. Agree in the offer which inspection features and cell types come with your machine.

Run a string trial on your own recipe
Start with your cells
Bring cells of the right technology, format and thickness. If you run HJT or another type, have it named in the model proposal.
Check loading and CCD
Ask which defects the supplied CCD setup catches and how rejected cells are taken out.
Solder and measure strings
Agree how joints are tested and how string position is checked. Judge the soldering by those results on your strings, whatever the brochure says about cameras or infrared heating.
Change over and repeat
If you run several recipes, switch ribbon, cell and string layout during the trial and record the first good result after each change.

Which inspection comes with your machine
CCD detection
The technical table lists CCD detection. Ask what defects it covers and test it with agreed good and faulty samples.
EL inspection
Ooitech's product text also talks about EL. Ask whether EL is fitted on your machine, where it sits and what records it produces, and get the answer onto the signed option list.
