solar cell laser scribing has performance of high scribing speed High precision Comprehensive functions Simple operation

Brief IntroductionAccording to the requirement of photovoltaic industry development, our company develops a new series of laser scribing machines, which can be widely used to scribe polycrystalline and mono cry

stalline silicon wafer, non-crystalline silicon solar cell, and to scribe and cut other substrate mater

ial of semiconductors such as silicon, Ge, GaAs Material and so on.

Configuration

Nd-YAG laser system Sound-optical modular Numerical controlled X,Y working table Vacuum adsorbing system Step motor drive controlled by computer

AdvantageThe system of the machine is developed with international prevalent modularization design and it

s key components are all imported high-quality ones. It has gained customers’ acknowledgemen

t and authorization.• It has the very good performance of high scribing speed • High precision • Comprehensive functions • Simple operation • Long workable time • Long term stability
