Innovative PCB Fabrication For Unsurpassed Quality And Flexibility
Key Steps In Printed Circuit Board Manufacturing:
1. Design: First, circuit board designers create circuit diagrams
and layouts using computer-aided design (CAD) tools. This includes
determining component locations, connections, and circuit paths.
2. Substrate Preparation: Non-conductive substrates are typically
made from fiberglass-reinforced epoxy resin. These substrates are
subsequently processed through cutting and lamination processes.
3. Conductive layer deposition: Deposition of conductive material
(usually copper) on the surface of a substrate to form a circuit
pattern. This can be done through chemistry, electroplating, or
other techniques.
Patterning: Using photolithography or etching to remove unwanted
portions of a conductive layer, leaving the desired circuit
pattern.
4. Component placement: Use automated equipment to accurately place
electronic components such as resistors, capacitors, and integrated
circuits onto circuit boards.
5. Soldering: Components and circuit boards are connected through a
soldering process. This can be done using surface-mount technology
(SMT) or through-mount technology (THT).
6. Testing and Quality Control: Once completed, the board goes
through a series of tests to ensure that all components are
connected correctly and the circuit is working properly. The
quality control process also includes visual inspection and
measurement.
