Etching

• Wet chemical etching – inexpensive but involves handling large volumes of harsh chemicals.
• Dry etching – plasma or laser etching is more environmentally friendly but requires higher capital investment.

Surface finishing

• Pumice scrubbing – prepares the PCB surface for subsequent plating processes. Usually manual or semi-automated.
• Desmear/etchback – removes resin smear after drilling and prepares surfaces for metallization. Uses wet chemicals or plasma.
• Hole metallization – electroless copper and direct metallization processes coat the drilling holes walls prior to electrolytic plating.

Drilling

• Mechanical drilling – traditional drilling using bits. Multiple drills required to handle different hole sizes.
• Laser drilling – fast and accurate but involves higher machine costs.

Lamination

• Hydraulic hot presses – applies pressure and heat to bond laminate layers. Standard in most PCB factories.
• Vacuum lamination – achieves better thickness uniformity but requires more expensive equipment.

Testing

• AOI – automated optical inspection checks for defects and quality errors. Essential for process control.
• Flying probe – tests electrical connectivity and isolates faults.
• ICT – in-circuit testing verifies functioning of completed boards.

Prioritize equipment investments based on your Target capabilities, production volumes, and capital budget. Buying used equipment can also reduce initial costs.
