Description
Technical Field
The invention relates to the related technical field of MWT photovoltaic components, in particular to a method for conducting resin quota testing of an MWT component.
Background
The MWT component adopts the conductive adhesive to replace the traditional solder strip, so that the illumination area is increased, and the component efficiency is improved. However, the conductive adhesive is excessive, unnecessary waste of the conductive adhesive can be caused, the copper foil and the aluminum back field of the battery piece can be lapped to cause scrap of black pieces and even components when the battery piece is extruded during lamination, and the conductive adhesive is less, so that insufficient welding can be caused. A method of rating the test is needed.
The loss of the conductive adhesive is required to be controlled, the prior art adopts the steps of weighing each unused conductive adhesive, then scooping the rest of adhesive and placing the adhesive into a adhesive box, and dividing the total amount of the scooped rest of adhesive by the number of the components made by the user by subtracting the total amount of the scooped rest of adhesive from the total amount of the used adhesive to obtain the adhesive amount of each component, and the method has many defects, such as the scooped adhesive is not completely scooped and remains on the screen plate; the amount of these glues is not at all counted when the through holes are dredged when the mesh plate holes are blocked. The nominal weight of the conductive paste is affected, thereby affecting the ability of us to adjust the weight of the conductive paste.
