How large of dome array can be made by laser cutting?

Thursday, November 12th, 2009

In recent years, with the emergence of laser cutting machine to make the dome array, so it doesn’t need to set up mold, greatly reducing the prodcution cost of dome array and increase Production efficiency.
So this way is choose by many customers to make dome array. But there are also encountered some customers aske to make a great area of dome array,then this involves that how large of dome array can be made by laser cutting?
At present, the maximum effective area of laser cutting is : 78mm * 88mm, so if the product over this size, we recommend that it should set up mold, or divide it into a few pieces,and then stick on the PCB together.

With the continuous development of scientific and technological level now, and I believe the effective area will be larger.
Ok, if you need more information, please feel free to contact us or see the below subject:
