Mastering Reflow Soldering: A Comprehensive Guide

Reflow soldering stands as the predominant method for attaching surface mount components onto Printed Circuit Boards (PCBs).

During the pick-and-place operation, components are situated on the board atop paste deposits. The reflow soldering process then facilitates a dependable electrical and physical connection. Solder pastes melt and subsequently cool to form robust solder joints, with the aim of achieving this without causing damage due to excessive heat.

The reflow soldering cycle typically comprises four stages: Preheat, Thermal Soak, Reflow, and Cooling.

Preheat: The oven gradually raises the temperature to heat the boards and components uniformly, paying attention to the temperature gradient to prevent component damage.

Thermal Soak: Activates flux particles, reducing oxidization, enhancing solder wetting, and promoting component longevity.

Reflow: Reaches the maximum temperature, dictated by the component with the lowest maximum temperature tolerance.

Cooling: Solder alloys solidify to form solder joints, ensuring proper wetting and preventing component damage or cold soldering.

In Reflow Soldering, quality is crucial, necessitating high-quality materials and meticulous profile optimization. Despite the time and effort invested in setting up an ideal Reflow Solder Profile for each assembly, it’s essential to achieve consistently reliable results.

Understanding the PCBA (Printed Circuit Board Assembly) Process


PCBA, which stands for Printed Circuit Board Assembly, is a crucial step in the manufacturing of electronic devices. It involves attaching electronic components to a printed circuit board (PCB) to create a functional electronic circuit. This intricate process forms the backbone of modern electronics manufacturing, and here, we delve into the various stages involved.

PCBA Process:

Solder Paste Stenciling:

After the bare PCB is fabricated, solder paste is applied to the pads for Surface Mount Technology (SMT).
Solder paste, composed of tin, silver, and copper, facilitates physical and electrical connections between components and the board.
A precise machine applies solder paste evenly, guided by a stencil tailored to the PCB layout.

Pick and Place:

A robotic pick-and-place machine rapidly positions Surface Mount Devices (SMDs) on the PCB.
These machines are programmed for specific projects, ensuring accurate component placement.
As components shrink in size, specialized machines handle the tiniest SMDs.

Reflow Soldering:

Once components and solder paste are in place, the PCB undergoes reflow soldering.
The board is heated in stages to 250°C, melting the solder paste and solidifying it as it cools.
This controlled process ensures secure component attachment.

Inspection and Quality Control:

After SMT, a thorough inspection checks physical and electrical connections.
Automatic Optical Inspection (AOI) machines use cameras to identify solder joint quality.
Defective boards are reworked or discarded based on quality standards.

Through-Hole Component Insertion:

Plated Through-Holes (PTH) are utilized when necessary for components.
These holes enable signals to pass through the board.
Workers manually insert PTH components into the board.

Wave Soldering:

Wave soldering is employed for mass production, eliminating hand soldering.
Boards move through a wave solder machine, where a molten solder wave solders the PTH components’ joints.
Care must be taken with double-sided PCBs to prevent damage.

Final Inspection and Functional Test:

The PCB undergoes a functional test simulating real-world conditions.
Electrical characteristics, such as voltage, current, and signal output, are examined.
Any deviations from predetermined ranges indicate a failed PCB.


After assembly, residual solder paste, oils, and contaminants are removed.
High-pressure washing with deionized water ensures a clean board.
The PCB is dried and prepared for packaging.


The PCBA process is the backbone of electronic manufacturing, ensuring the creation of reliable and functional electronic devices. Each stage, from soldering to testing, plays a vital role in producing high-quality PCBAs that power our modern world. Understanding this process sheds light on the complexity and precision required in electronics manufacturing.

Empowering Connectivity: The Evolution of 5G CPE Technology

5G CPE, or 5G Customer Premise Equipment, is a device that connects to a 5G network and provides internet access to other devices via Wi-Fi or Ethernet. 5G CPE can offer faster and more reliable internet service than traditional routers or modems, as it can support higher bandwidth, lower latency, and wider coverage. In this article, we will share our development experience for 5G CPE, from schematic design to PCB assembly.

Schematic Design

The first step of our development process was to design the schematic of the 5G CPE device. The schematic is a graphical representation of the electrical connections and components of the device. The schematic shows how the power supply, the 5G module, the Wi-Fi module, the Ethernet module, the antenna, and other parts are connected and configured. The schematic also specifies the values and ratings of the resistors, capacitors, inductors, diodes, transistors, and other components.

To design the schematic, we used [EAGLE], a software tool that allows us to create and edit schematic diagrams easily and efficiently. EAGLE has a library of thousands of standard components that we can drag and drop into our schematic. EAGLE also has a simulation feature that allows us to test and verify our schematic before moving on to the next step.

The second step of our development process was to design the PCB layout of the 5G CPE device. The PCB layout is a physical representation of the arrangement and placement of the components and traces on the printed circuit board. The PCB layout shows how the components are mounted on the board, how the traces are routed between them, and how the board is shaped and sized.

To design the PCB layout, we used [KiCad], a software tool that allows us to create and edit PCB layouts easily and efficiently. KiCad has a feature that allows us to import our schematic from EAGLE and automatically generate a PCB layout based on it. KiCad also has a 3D viewer that allows us to see how our PCB layout looks like in real life.

PCB Assembly

The third and final step of our development process was to assemble the PCB of the 5G CPE device. The PCB assembly is the process of soldering the components onto the printed circuit board according to the PCB layout. The PCB assembly requires precision and accuracy, as any mistake or defect can affect the performance or functionality of the device.

To assemble the PCB, we used [JLCPCB], a professional PCB manufacturer that offers high-quality PCB assembly services at low prices. JLCPCB has a feature that allows us to upload our PCB layout file and order our PCBs online. JLCPCB also has a large inventory of standard components that we can choose from for our PCB assembly. JLCPCB can deliver our assembled PCBs within a few days.
