Printed circuit boards (PCBs) are essential components in almost all electronic devices today. Depending on application requirements, they are made from various materials such as FR4, plastic, fiberglass, and copper. However, some mission-critical applications demand specialized PCBs designed using unique materials. RF (radio frequency) and microwave PCBs are specifically crafted to operate in medium to high-frequency ranges, making them crucial for applications in smartphones and military radars. This blog explores the essential aspects of RF and microwave PCBs and what it takes to manufacture them.

Key Materials for RF and Microwave PCBs

Not all PCB manufacturers possess the infrastructure to produce RF and microwave PCBs. These boards require advanced materials and technology to meet the high demands of modern electronics. Here are some critical elements involved in manufacturing these specialized PCBs:

  • High-Quality Materials: RF and microwave PCBs are often made with superior quality FR4 materials, PTFE woven with microfiber glass, or ceramic-filled hydrocarbons. These materials provide the necessary stability and performance.
  • Thermal Expansion: The materials used have a good coefficient of thermal expansion (CTE), ensuring the boards remain stable under extreme temperature conditions.
  • Smooth Surface Finish: The copper and core material surface finish must be smooth to facilitate high-speed signal transmission with minimal impedance.
  • Complex Design Compatibility: These PCBs can accommodate fine pitch components and complex designs, often exceeding 20 or 30 layers, due to their superior material properties.
  • Frequency Range: RF PCBs typically operate in the 500 MHz to 2 GHz range, while microwave PCBs support frequencies beyond 2 GHz. This differentiation is crucial for their respective applications.

Manufacturing Process of RF and Microwave PCBs

Creating RF and microwave PCBs involves specific processes and advanced equipment:

  • Material Selection: The choice of materials such as high-quality FR4, PTFE, and ceramic-filled hydrocarbons is crucial for achieving the desired performance.
  • Precision Drilling: Plasma etch machinery is used to create through-holes with tight tolerances and minimal deviation.
  • Laser Imaging: Laser equipment is employed for imaging and achieving tight tracing widths, ensuring precision in the circuit design.
  • Thermal Management: Effective heat management is critical for high-frequency PCBs. Coating and laminating materials must enable efficient heat transfer through conduction, convection, and radiation.

Understanding Surface Mount Technology: Essential For Modern PCB Assemblies

Printed circuit boards (PCBs) have been an essential component of electronic devices since the 1960s, playing a critical role in their performance and functionality. Today, PCBs are integral to many devices, featuring numerous tiny components meticulously mounted on their surfaces. This intricate mounting process is known as surface mount technology (SMT), which has become almost universal in PCB assembly due to its numerous advantages. In this post, we will explore different types of surface mount components and outline the steps involved in the SMT PCB assembly process.

Different Surface Mount Component (SMC) Packages:

As the demand for smaller and more powerful devices grows, the importance of compact surface mount component packages increases. These packages generally appear as flat structures with tiny lead pins soldered to them, but their designs can vary significantly. Here are some of the most popular SMC packages:

  • BGA (Ball Grid Array): The most common surface mount component package, used for permanent mounting in devices like microprocessors.
  • SOIC (Small Outline Integrated Circuit): Thinner and more space-efficient than DIP packages, contributing to the development of thin small outline packages (TSOP) and thin-shrink small-outline packages (TSSOP).
  • QFN (Quad-Flat No Leads): Similar to BGA and QFP packages, these help connect ICs to PCB surfaces effectively.
  • QFP (Quad Flat Package): Easily identifiable by their gull-wing leads, these packages range from 32 to 304 pins with pitch sizes from 0.4 to 1.0mm.
  • PLCC (Plastic Leaded Chip Carrier): Featuring a plastic casing, similar to QFP but with larger pitch sizes, commonly used in programmable components and NOR flash memories.
  • POP (Package on Package): Combines BGA and discrete logic packages for higher component densities, commonly seen in PDAs, digital cameras, and mobile phones.

The SMT PCB Assembly Process: 

The SMT PCB assembly process begins with selecting components and creating PCB layouts using various software tools. Components are packaged in different formats, such as tubes, reels, and trays. Following these preparatory steps, the SMT assembly process involves the following key stages:

  • Solder Paste Printing: The process starts here, with solder paste applied to the PCB pad using a stencil and solder paste printer. This step is crucial as it forms the foundation of the PCB assembly.
  • Inspection of Solder Paste: A built-in or separate solder paste inspection system checks the solder paste volume on the pad and print area to ensure accuracy.
  • Placement of Components: Components are picked from their packaging using a gripper or vacuum nozzle, checked for appropriateness, and placed on the printed area at high speed.
  • Inspection: Automated Optical Inspection (AOI) machines verify component placement before reflow soldering, ensuring correct positioning, polarities, and values.
  • Reflow Soldering: The assembly is heated to a pre-set temperature to create electrical solder connections. Achieving the correct reflow profile is critical to avoid damaging solder joints.
  • Reflow Soldering Inspection: AOI and X-ray inspections check the quality of soldered joints and BGA components for any defects such as voids or broken joints.

Innovations In Temperature-Sensing Technology Streamline PCB Assembly Processes

The latest advancements in temperature-sensing technology have transformed PCB assembly by eliminating the need for adhesives in thermocouple attachment.

In the domain of large surface mount packages, the complexity of rework procedures, particularly applying heat to peripheral lead attach areas, presents challenges. This complexity amplifies with Ball Grid Arrays (BGAs), where intricate physical and electrical connections are established through grids of solder balls beneath components. Achieving an accurate temperature profile requires placing a thermocouple against a pad near the BGA’s center. Traditional methods face limitations, especially when BGAs lack adequate clearance underneath, leading to uncertainty in connecting the thermocouple to the central ball.

Conventional techniques involve drilling or milling a hole through the PCB’s back to access a pad near a central ball and attaching a thermocouple beneath it. Although effective, these methods are time-consuming and intricate.

An innovative approach involves drilling a 1/32 hole through the PCB’s back near a central ball. Using a specialized thermocouple probe called a “Temprobe,” it is clipped to the PCB’s edge with its probe positioned underneath. The Temprobe’s thermocouple tip is inserted into the hole against the pad. Simultaneously, a second thermocouple probe is clipped to the PCB’s top side, with its thermocouple tip resting on a pad near the BGA. This novel setup enables precise profiling and heating of the PCB to the required temperature, measured by both thermocouple probes simultaneously.

For BGA profile verification, a Temprobe can be clipped to a production PCB, placed on the reference point, and run through the profiling process. This data is then compared to the original reference profile for validation. This groundbreaking approach eliminates the need for soldering, bonding, or taping thermocouples to the PCB, streamlining work processes, and making PCB assembly faster and more manageable.

At Gelco EMS, we’re committed to implementing pioneering technologies to streamline and optimize PCB assembly processes. Our dedication to innovation ensures the delivery of efficient, reliable, and forward-thinking solutions that meet our clients’ evolving needs.

As the New Year approaches, Gelco EMS extends warm wishes for a prosperous and innovative year ahead. May the coming year be filled with breakthroughs, success, and technological advancements for all our partners and clients.
