Apparatus for processing printed circuit board substrates

摘要

Apparatus for contacting a circuit board substrate with etching fluid or some other chemical includes a conveyor system comprised of upper and lower rotating disks for receiving and transporting the circuit board substrate while the substrate is contacted with fluid. The apparatus utilizes a modular drive system to drive the disks. The drive system is not exposed to the chemicals used to contact and process the circuit board substrate. The rotating disks can be removed from the apparatus without requiring disassembly of the modular drive system.
