Your Source for Accurate and Reliable PCB Board Assembly

In the fast-paced electronics industry, precision is everything. At Arrival Electronics Limited, we understand that every component, every solder joint, and every process in manufacturing impacts the final performance of an electronic device. That’s why we treat pcb board assembly not just as a technical task but as a craft one that demands attention to detail, industry expertise, and a commitment to quality from start to finish.

Over the years, we’ve worked with clients across industries who rely on us to deliver dependable assembly solutions. Our experience has taught us that successful projects don’t happen by chance; they result from meticulous planning, skilled execution, and ongoing collaboration with our customers. We pride ourselves on providing assembly services that consistently meet demanding performance and compliance standards.

A Closer Look at the Assembly Process

Printed Circuit Board (PCB) assembly is the process of placing and soldering electronic components onto a PCB to create a fully functioning circuit. While the concept may sound straightforward, it involves multiple stages that require specialized skills, advanced equipment, and strict quality control.

In modern electronics manufacturing, even a tiny variation in assembly can affect performance, reliability, and lifespan. That’s why our team focuses on delivering assemblies that meet not only our clients’ specifications but also the stringent requirements of international standards.

Step-by-Step Guide to the Assembly Process

Each project follows a structured process designed to achieve consistent, high-quality results. Here’s an overview of the stages we follow:

1. Design Review and Preparation

Before the first component is placed, we review the PCB design files in detail. This step ensures that the layout is suitable for assembly, components are correctly specified, and any potential issues are identified early. Our engineering team often collaborates with clients during this stage to make adjustments that improve manufacturability and efficiency.

2. Solder Paste Application

Solder paste is applied to the pads where components will be mounted. We use precise stenciling equipment to ensure accurate application, as the volume and placement of solder paste are critical to forming strong and reliable connections.

3. Component Placement

Using automated pick-and-place machines, components are positioned on the board with pinpoint accuracy. These machines operate at high speed but maintain strict tolerances, ensuring each component is correctly oriented and placed.

4. Soldering Process

For surface-mount technology (SMT), the board passes through a reflow oven, where heat melts the solder paste, bonding the components to the board. For through-hole components, we use wave soldering or selective soldering techniques to create durable connections.

5. Inspection and Testing

Quality assurance is not an afterthought, it's built into every stage. We conduct both automated optical inspection (AOI) and manual visual checks to verify solder joints, component placement, and polarity. Functional testing is performed when required to ensure the assembled PCB operates as intended.

6. Packaging and Delivery

After passing all inspections, the boards are carefully packaged to prevent damage during transport. We make sure our clients receive their assemblies in perfect condition, ready for integration into their final products.

Our Approach to Quality

We believe that quality in pcb board assembly begins long before production starts and continues after the boards leave our facility. This philosophy shapes everything we do:

• Rigorous Supplier Selection – We work only with trusted component suppliers to ensure authenticity and compliance with industry standards.
  
  

• Process Control – Every step of assembly follows documented procedures, with regular calibration of our equipment.
  
  

• Continuous Training – Our technicians receive ongoing training to stay up to date with the latest assembly methods and industry regulations.
  
  

• Traceability – From components to production batches, we maintain detailed records for accountability and quality tracking.

This systematic approach allows us to maintain consistency, reduce rework, and meet demanding delivery schedules without compromising on workmanship.

SMT and Through-Hole Methods

Different applications require different assembly methods. We provide both SMT and through-hole assembly, as well as mixed-technology solutions, depending on the product’s requirements.

• SMT – Offers compact design, lighter weight, and high-speed assembly, ideal for consumer electronics, telecommunications, and medical devices.
  
  

• Through-Hole – Delivers stronger mechanical bonds, making it suitable for high-power applications, automotive electronics, and industrial equipment.

By offering both methods, we can handle a wide variety of projects, from prototype runs to large-scale production.

Handling Complex Assemblies

Some boards are more challenging than others whether due to high component density, fine-pitch components, or specialized materials. Our team has experience with:

• Fine-pitch ICs
  

• Ball grid arrays (BGAs)
  

• Rigid-flex PCBs
  

• High-frequency boards
  

• High-reliability military and aerospace assemblies

Our facility is equipped with advanced placement, soldering, and inspection equipment to handle even the most intricate designs while meeting tight tolerances.

Working Closely with Our Clients

One of the reasons our customers return to us is the level of collaboration we provide. We believe that communication is as important as technical expertise. Throughout the process, we keep clients informed of progress, share inspection results, and discuss any adjustments needed.

This approach helps avoid misunderstandings, reduces the risk of production delays, and ensures the final product matches expectations.

Prototyping and Low-Volume Runs

Before committing to full production, many clients choose to create prototypes. This step allows for functional testing, design validation, and early detection of potential issues.

We specialize in rapid-turnaround prototyping, helping clients meet tight development timelines. Low-volume runs are also available for specialized products, pilot programs, or niche markets.

Meeting Industry Standards

Compliance with international standards is critical in electronics manufacturing. We follow guidelines such as:

• IPC-A-610 for assembly workmanship
  

• RoHS (Restriction of Hazardous Substances) compliance
  

• ISO 9001 for quality management systems

By adhering to these standards, we give our clients confidence that their assemblies are built to perform reliably in the field.

Supporting Diverse Industries

Our assembly services cater to a wide range of industries, including:

• Consumer Electronics – Smartphones, wearables, smart home devices
  

• Medical Equipment – Diagnostic tools, monitoring devices, patient care systems
  

• Automotive Electronics – Engine control units, infotainment systems, safety sensors
  

• Aerospace and Defense – Navigation systems, communication devices, ruggedized equipment
  

• Industrial Automation – Control panels, sensors, power management systems

Each sector has unique requirements, and our flexibility allows us to meet them all with precision.
