Hot spot effect substantially reduces the harm of component.
Current imbrication component package is broadly divided into two kinds of core process of printing and dispensing.Wherein printing technology is each at present
What major company and headend equipment manufacturer generallyd use, which carries out a subsynchronous print according to a sheet or two are large stretch of
Then brush carries out sliver separation respectively again.Patch is carried out after vision-based detection positions to form imbrication battery strings, basis later

It transports on printing table, the halftone for selecting matched screen frame to carry conductive adhesive printed pattern is printed.This printing is led
The mode of electric glue manufacture imbrication battery strings mainly has following disadvantage:
First, single large stretch of or synchronous printing of two sheets, practical printing process production capacity is low and flexibility ratio is weak, no
It is able to satisfy low-coat scale production requirement, production efficiency is low.
Second, since single large stretch of or two sheets are final or realize by laser or wire cutting mode and be separated into one
Five small pieces or all six small pieces are cut, to ensure patch precision, small pieces separation is according to large stretch of equal part.Large stretch of cell piece exists
Metallization pattern size and position have fluctuation deviation in battery-end screen printing process, in this way can not be to imbrication sheet battery
Piece is precisely printed.
Third, halftone belongs to high consumptive material, monolithic battery piece print pass greatly increases production process consumables cost.
Fourth, the conductive adhesive limited mass carried on single halftone, moves back and forth the conductive gluing of stirring for scraper
