Which statement accurately describes the acid bath process in PCB production?

The acid bath process in PCB (Printed Circuit Board) production is accurately described by the statement that it has a higher initial cost but is cost-effective for mass production. This is because the acid bath process requires specialized tanks and chemical solutions, leading to a significant upfront investment. However, once established, the process allows for efficient and consistent etching of copper on PCBs, which is particularly advantageous when producing large volumes.

In mass production scenarios, the scalability and efficiency of the acid bath process reduce the cost per unit as production volumes increase. This balance of initial cost against long-term savings makes it a suitable choice for manufacturers aiming to produce PCBs in large quantities while maintaining quality and precision.
