[0002] Copper clad laminate is the basic material for making PCB boards. After the copper clad laminate is processed, one or more stacked copper clad laminates need to be transferred to a storage location, packaging location or cutting location for further processing.

[0003] After the copper clad laminate is conveyed by the copper clad laminate feeding equipment to the location of the shearing device for shearing and trimming, an electronic circuit substrate is formed.
