3. Inner Layer Processing

For multilayer PCBs, the inner layers are processed first:

1. Copper-clad laminate is cleaned and prepared.
2. A photoresist layer is applied.
3. The circuit pattern is transferred using photolithography.
4. Unwanted copper is etched away.
5. The remaining photoresist is stripped.

4. Layer Alignment and Pressing

Once the inner layers are processed:

1. They are carefully aligned using registration holes.
2. Prepreg (pre-impregnated) layers are placed between the copper layers.
3. The stack is pressed under high pressure and temperature to fuse the layers.

5. Drilling

Holes are drilled for vias, through-holes, and mounting holes using high-speed drilling machines. Computer-controlled systems ensure precise hole placement.

6. Plating and Filling

After drilling:

1. The board is plated with copper to create conductive walls in the holes.
2. Vias may be filled with conductive or non-conductive materials for specific designs.

7. Outer Layer Processing

The outer layers undergo a similar process to the inner layers:

1. Photoresist application
2. Pattern transfer
3. Etching
4. Photoresist stripping

8. Solder Mask Application

A solder mask layer is applied to protect the copper traces and prevent solder bridges during component assembly.

Cons:

• Material waste
• Limitations in achieving very fine traces

2. Additive Process

Copper is selectively added to create the circuit pattern.

Pros:

• Reduced material waste
• Capability for finer traces and spaces

Cons:

• Slower than subtractive process
• Higher cost for low volumes

3. Semi-Additive Process

A combination of additive and subtractive techniques.

Pros:

• Balances the advantages of both additive and subtractive methods
• Suitable for high-density interconnect (HDI) boards

Cons:

• More complex process
• Higher cost compared to purely subtractive method

4. Modified Semi-Additive Process (mSAP)

An advanced version of the semi-additive process, used for ultra-fine line PCBs.

Pros:

• Enables extremely fine lines and spaces (below 30 μm)
• Excellent for advanced smartphone and tablet PCBs

Cons:

• Higher cost
• Requires specialized equipment

PCB Assembly Methods

Once the PCB is fabricated, components need to be assembled onto the board. There are two primary methods of PCB assembly:

1. Through-Hole Technology (THT)

Components have leads that are inserted through holes in the PCB and soldered on the opposite side.

Pros:

• Strong mechanical bonds
• Suitable for high-reliability applications
• Easier manual assembly and rework

Cons:

• Limited component density
• More expensive for high-volume production

2. Surface Mount Technology (SMT)

Components are mounted directly onto the surface of the PCB.

Pros:

• Higher component density
• Faster automated assembly
• Better performance for high-frequency applications

Cons:

• Less mechanical strength
• More challenging for manual assembly and rework

Many modern PCBs use a combination of THT and SMT to leverage the advantages of both methods.

SMT Assembly Process

The SMT assembly process typically involves the following steps:

1. Solder Paste Application: A stencil is used to apply solder paste to the PCB pads.
2. Component Placement: Pick-and-place machines accurately position components onto the board.
3. Reflow Soldering: The board passes through a reflow oven, melting the solder paste to create electrical and mechanical connections.
4. Inspection: Automated optical inspection (AOI) or X-ray inspection ensures correct component placement and soldering quality.
5. Through-Hole Component Insertion: If required, THT components are manually or automatically inserted.
6. Wave Soldering or Selective Soldering: Used to solder THT components.
7. Final Inspection and Testing: Ensures the assembled PCB meets all specifications.

Quality Control and Testing

Maintaining high quality standards is crucial in PCB fabrication and assembly. Various quality control measures and testing procedures are employed throughout the process:

1. In-Process Quality Control

• Visual Inspection: Regular visual checks during fabrication and assembly.
• Automated Optical Inspection (AOI): Machine vision systems detect defects in PCB patterns and component placement.
• X-ray Inspection: Especially useful for inspecting hidden solder joints in ball grid array (BGA) components.

2. Electrical Testing

• Flying Probe Test: Flexible testing method suitable for low-volume or prototype boards.
• In-Circuit Test (ICT): Uses a bed-of-nails fixture for high-speed testing of high-volume production.
• Functional Testing: Verifies the board's performance under operational conditions.

3. Environmental Testing

• Thermal Cycling: Tests board performance under varying temperature conditions.
• Humidity Testing: Ensures board reliability in high-humidity environments.
• Vibration and Shock Testing: Verifies mechanical durability.

4. Reliability Testing

• Highly Accelerated Life Test (HALT): Subjects boards to extreme conditions to identify potential failures.
• Burn-in Testing: Operates boards under stress for an extended period to catch early failures.

5. Compliance Testing

• EMC/EMI Testing: Ensures electromagnetic compatibility and low emissions.
• Safety Testing: Verifies compliance with relevant safety standards.
