Comprehensive PCB Assembly Services

Four Points Platinum provides a full spectrum of PCB assembly services, tailored to your specific project requirements. Our expertise covers:

Surface Mount Technology (SMT) Assembly

SMT is the cornerstone of modern electronics manufacturing, enabling the creation of compact, high-performance circuit boards. Our SMT capabilities include:

• Fine-Pitch Component Placement: Handling of ultra-small and densely packed components, including BGAs, QFNs, and 0201/01005 packages, with exceptional accuracy.
• Automated Pick-and-Place: State-of-the-art automated equipment ensures high-speed, high-precision component placement, critical for volume production and consistent quality.
• Reflow Soldering: Precisely controlled reflow ovens ensure optimal solder joint integrity and reliability, crucial for long-term product performance.
• Double-Sided Assembly: Capabilities for populating components on both sides of the PCB, maximizing board real estate and functionality.

Through-Hole (TH) Assembly

While SMT dominates, Through-Hole technology remains vital for components requiring greater mechanical strength, higher power handling, or specific form factors. Our TH assembly services include:

• Manual and Automated Insertion: Efficient and accurate insertion of through-hole components, from connectors and relays to capacitors and inductors.
• Wave Soldering: Precisely controlled wave soldering processes ensure robust and reliable solder joints for through-hole components.
• Selective Soldering: For boards with mixed SMT and TH components, selective soldering provides targeted and precise soldering, preventing thermal damage to sensitive SMT parts.

Mixed Technology Assembly

Many contemporary electronic designs incorporate both SMT and Through-Hole components. Our facility is equipped and our processes are optimized to seamlessly integrate both technologies onto a single board, ensuring optimal functionality and manufacturability. This hybrid approach allows for design flexibility, combining the density of SMT with the robustness of TH components where needed.

Quality Assurance and Reliability

Quality is paramount in PCB assembly. Our processes are designed to ensure the highest levels of reliability and performance for your assembled boards. Key aspects of our quality assurance include:

• Automated Optical Inspection (AOI): High-speed optical inspection systems detect defects such as missing components, incorrect polarity, solder bridges, and insufficient solder, ensuring early detection and correction.
• X-Ray Inspection: For complex components like BGAs and QFNs, X-ray inspection verifies solder joint integrity beneath the package, ensuring hidden connections are sound.
• Functional Testing (FCT): Upon request, we can integrate functional testing to verify that the assembled PCB performs according to your specifications, reducing field failures and improving product uptime.
• In-Process Quality Checks: Throughout the assembly process, our skilled technicians perform rigorous visual inspections and quality checks to maintain consistency and adherence to specifications.

Design for Manufacturability (DFM) Consultation

Leveraging our extensive experience, Four Points Platinum offers valuable Design for Manufacturability (DFM) consultation services. By engaging with us early in your design cycle, we can help identify potential manufacturing challenges, optimize component selection, and suggest layout improvements that can:

• Reduce Production Costs: By streamlining assembly processes and minimizing material waste.
• Improve Yields: By addressing design elements that could lead to defects.
• Enhance Reliability: By ensuring robust solder joint design and proper thermal management.
• Accelerate Time to Market: By preventing costly redesigns and rework during production.

Our DFM insights are particularly beneficial for complex boards, high-volume production, and applications where reliability is non-negotiable. This proactive approach helps procurement teams and operations managers mitigate risks and ensure a smoother production ramp-up.
