ATMA introduces a range of new Solar Cell screen printing machines
22 August 2020: Taiwan based ATMA Champ Ent. needs no introduction in the world of screen printing. The company has now introduced a range of new Solar Cell screen printing machines. It is also called as Silicon Wafer Screen Printing Machine or Photovoltaic (PV) Screen Printing Machine.
According to the company, silver (or Silver-Aluminum) fingers and busbars are printed on crystallized / non-crystallized silicon wafer for making solar cell panel. Low breakage and high yield rate are necessary to meet the essential requirement for silicon solar cell high efficiency and low cost.
So, ATMA’s screen printing machines are based on innovative design and quality engineering to provide an effective solution to meet an essential requirement. ATMA offers high precision screen printing line with vision system registration to print silver or sliver-aluminium paste fingers and busbars onto mono-crystalline or polycrystalline silicon wafer in size 5” & 6”
ATMA offers two models:
1) CCD Centered Registering Screen Printer for Green Energy Silicon Wafer: ATMASC 25PP. It is built as per Silicon Wafer (mono crystallized wafer & multi-crystallized wafer)/Solar Cell industry requirement for midstream processing of solar cell electrode screen printing. It is fitted with registration pins and pop-up pins which are co-existed on the tabletop. Registration pins are convenient for alignment (5” and 6” Silicon Wafer), and pop-up pins are convenient to off-load manually. The registration section is equipped with 6 CCD cameras to detect target on wafer or edge and feedback to control system compare position.
The X/Y/? servo motor transmission system activates to move registration platform to a precise position (together along with substrate on the tabletop) to accomplish alignment. The machine is collocated with silencer for vacuum positioning which assures the substrate is firmly on the tabletop while sliding movement or printing. It has HMI displays Chinese / English language, digitalized control for quick selection, setting, various printing stroke cycle correspondence with multi-printing demand.
2) Green Energy Silicon Wafer Screen Printer: AT-25PSC. It is designed as per silicon wafer (mono crystallized & multi-crystallized) solar cell industry, midstream solar cell electrode screen printing process. It is fitted with registration pins and pop-up pins, co-existed on the tabletop. Registration pins are convenient for alignment (5” and 6” wafer) and pop-up pins are convenient for off-loading after printing. It has HMI electrical control, versatile function, digital control setting, auto error diagnosis.
