The transparent cephacoria of person, lamination, attaching wire box；Transparent cephacoria can be used flexibility and block water film to increase the degree of safety of toughness and transport；
2) conductive backings are 3-tier architecture, and backboard+EVA+ copper foil is combined with each other by high temperature；
3) small size MWT component copper foil circuit is divided into 4 strings, 9 junior units of every string, corresponding 1/3 cell piece of each unit；
4) small size MWT component insulation layer hole is divided into 4 strings, 9 units of every string, 153 holes of each unit.
5) lamination process needs 150 DEG C of high temperature, vacuumizes 360 seconds, pressurizes 600 seconds；4 are first welded when terminal box is installed to draw
Outlet, then terminal box gluing is fixed on backboard, then lead-out wire is welded on the binding post in terminal box, last glue-filling solid
Change, establishment of component finishes.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, without departing from the principle of this utility model, can also make several improvements, these improvement also should be regarded as
The protection scope of the utility model.
