1） SMT Tape Reel:
The tape reels, which are suitable for SMT, have been made for most GOSUNCN modules. If the module has provided the tape reel
itself and meets the SMT requirements, customers can directly use it for module SMT.

NOTE:
Figure7-2 is just for reference, it doesn’t represent the actual Material Module Tape Reel.
Otherwise, customers need make a loading tool similar to the tape reel. Customers can take out the module from the packaging
box, put them into the tape according to the sequence and direction, and then start SMT.
