PCB Manufacturing

PCB manufacturing is a crucial process in the electronics industry, involving the fabrication of printed circuit boards (PCBs) to host and interconnect various electronic components, thereby constructing fully functional electronic devices. PCBs serve as the backbone of modern electronic products, spanning from small-scale consumer electronics to complex industrial machinery and communication systems.


The initial step in PCB manufacturing is fabricating the PCB according to the design requirements. This involves laminating layers of copper and insulating material to create a multilayered board. The next step is etching the copper layers to form intricate circuit patterns, defining the electrical connections and pathways for the components.


Once the PCB is fabricated, the process moves to the assembly stage. Electronic components, such as resistors, capacitors, integrated circuits, and connectors, are precisely placed on the PCB using automated pick-and-place machines. This accurate positioning is essential for ensuring optimal performance and reliability.


Following component placement, soldering takes place, forming durable electrical connections between the components and the PCB. The soldering process can involve surface mount technology (SMT) or through-hole technology (THT), depending on the design and requirements of the PCB.


Quality control and testing play a pivotal role in PCB manufacturing. Automated Optical Inspection (AOI) and X-ray inspection are employed to identify any defects or faults in soldering and component placement. Rigorous testing procedures verify the electrical functionality of the PCBs to meet the specified standards and requirements.


PCB manufacturing also considers aspects like thermal management and electromagnetic compatibility. Efficient heat dissipation techniques and optimized trace routing are essential to prevent overheating and ensure stable operation. Design considerations are made to minimize electromagnetic interference, maintaining signal integrity and reducing potential issues.


Upon passing quality inspection and testing, the PCBs may undergo cleaning processes to remove any flux residues and contaminants, ensuring the longevity and reliability of the PCBs. Protective coatings, such as conformal coatings, may also be applied to shield the PCBs from environmental factors like moisture and dust.


PCB manufacturing finds applications in diverse industries, encompassing consumer electronics, automotive, aerospace, telecommunications, healthcare, and industrial automation. It plays a critical role in enabling the production of cutting-edge electronic devices, supporting technological advancements, and driving innovation in today's interconnected world.

PCB Manufacturing Process:

1. Gold-plating process: the vertical HASL process is very difficult to flatten very thin pads, which brings difficulty to SMT placement. In addition, the shelf life of the HASL is very short, and gold-plating just solves the problem. these problems.

2. Immersion gold process: The purpose of the immersion gold process is to deposit a nickel-gold coating with stable color, good brightness, flat coating and good solderability on the surface of the printed circuit board. Basically, it can be divided into four stages: pre-treatment (oil extraction, micro-etching, activation, post-immersion), nickel immersion, gold immersion, and post-treatment (waste gold washing, DI washing, drying)


3. Leaded HASL: Leaded eutectic temperature is lower than lead-free, the specific amount depends on the composition of the lead-free alloy, such as the total gold of SNAGCU 217 degrees, the soldering temperature is the eutectic immersion plus 30 degrees or 50 degrees, It depends on the actual adjustment, the lead eutectic is 183 degrees, the mechanical strength, brightness, etc. are better than lead-free.

4. Lead-free HASL: lead will increase the activity of tin wire in the soldering process, lead-tin wire is better than lead-free tin wire, but lead is poisonous, long-term use is not good for human health, and lead-free tin will It is brighter than lead-tin melting, so the solder joint is much stronger.

5. SOP (anti-oxidation): It has anti-oxidation, thermal shock resistance, and corrosion resistance. It is used to protect the copper surface from rusting (oxidation or carbonization) in a normal environment: but in the subsequent welding high temperature, this protection The film must be easily removed quickly by the flux so that the exposed clean copper surface can be melted and soldered immediately in a short time to become a firm solder joint.
