Small And Medium Batch PCB Assembly

What Is Small And Medium Batch PCB Assembly

Small and medium batch PCB assembly refers to the placement and welding of components for PCBs (printed circuit boards) with small orders in the manufacturing process of electronic products. PCB is an important part of electronic products, on which various electronic components, such as integrated circuits, resistors, capacitors, inductors, etc., are used to realize circuit functions.

SCSPCBA provides small and medium batch PCB assembly, which is carried out by our professional PCB assembly factory.

Small and medium batch PCB assembly is suitable for electronic product sample production, small-scale production, fast delivery and other needs, and is an important link in the development and production process of electronic products.

Preparatory Work for Small And Medium Batch PCB Assembly
PCB Assembly Component Procurement And Management

PCB Design and Layout Optimization
Before starting the assembly, SCSPCBA will first confirm with the customer and carry out PCB design according to the needs to ensure that the PCB layout is reasonable, meets the functional requirements of the circuit, and is suitable for subsequent component mounting and welding. Optimizing layout can improve signal transmission efficiency and thermal performance.

Component Procurement And Management
According to the bill of components (BOM) of PCB design, select the appropriate component supplier and purchase components. SCSPCBA has an intelligent component warehouse, no need for customers to find other component suppliers, we provide customers with the required components, to achieve timely supply, to avoid delays in PCB assembly progress.

Steel Mesh Production and Debugging
The stencil is a key tool for positioning and pasting SMT components and makes a steel mesh according to the PCB design file.
Mechanical Placement of SMD Components
SCSPCBA uses automated placement equipment to quickly paste surface mount components on the PCB.

Manual Insertion of Plug-in Components
Some components on the PCB cannot be mounted by automatic placement equipment, and need to be placed through manual insertion.
Welding Process and Debugging
Through the wave soldering or reflow soldering process, weld the components to the PCB, and check the welding quality.

How Does SCSPCBA Ensure the Quality Control of PCB Assembly in Small and Medium Batches

SCSPCBA is a one-stop PCBA manufacturing service provider with rich experience
SCSPCBA also provides assistance in PCB design, PCB manufacturing and assembly testing
It is based on IPC standards for small and medium-batch PCB assembly
The workshop is also equipped with online SPi and online AOI testing equipment

Formulate Small and Medium Batch PCBA Quality Control Plan:

PCB Assembly Requirements
Clarify the customer’s PCB assembly quality requirements and performance standards, including key parameters such as PCB size, component specifications, and soldering quality. Ensure the accuracy of PCB design documents so that subsequent PCB fabrication and testing processes can meet these requirements.
Establish PCB Assembly Process
From raw material procurement, PCB manufacturing, component procurement, patch soldering, reflow soldering, functional testing and packaging. SCSPCB has detailed process standards and operating guidelines for each link.
Training and Certification
SCSPCBA requires pcb assembly production operators to receive necessary pcb assembly knowledge training and master key process skills and quality control points. At the same time, operators are certified to ensure that they comply with relevant standards and requirements.
Establish Quality Indicators
SCSPCBA establishes key indicators for measuring PCB assembly products, such as soldering quality, component accuracy, and dimensional deviation. Through real-time monitoring and data collection, potential problems can be detected and corrected in time.

Online and Offline Detection

In PCB assembly, scspcba uses advanced AOI equipment to check the quality and integrity printed circuit board

On-line Inspection
In the process of PCB production, automatic equipment and an online DFM inspection system are introduced to catch potential problems in time. For example, automated optical inspection (AOI) systems are employed to check component mounting positions and deviations, and soldering quality to standards.
Offline Detection
Conduct offline sampling detection to verify the accuracy of online detection results. Laboratory testing is carried out by taking samples to confirm whether the product quality is as expected.
X-ray Inspection
For components that are difficult to inspect directly such as BGA (Ball Grid Array), X-ray inspection technology is used to ensure the quality and integrity of solder joints.● Functional Testing
After the assembly is completed, conduct functional testing to verify whether the performance of the PCB meets the design requirements.

PCB Assembly Troubleshooting and Repair

Introduce A Traceability Mechanism
SCSPCBA establishes a traceability mechanism throughout the printed circuit board production process to record the operating data and key parameters of each link. Once a problem occurs, the point of failure can be quickly located so that measures can be taken quickly.
Troubleshooting Team
SCSPCBA has set up a special troubleshooting team, which is composed of experienced technicians. For complex PCB assembly faults, conduct in-depth cause analysis and formulate corresponding repair plans.
Regular Maintenance
Regularly maintain and maintain PCB fabrication and PCBA manufacture production equipment to ensure that they are always in the best condition.
Defective Product Handling
When there are defective PCBs or PCBAs, SCSPCBA will promptly isolate and investigate the cause of the defective PCB assembly, conduct a detailed analysis and take corrective measures to avoid similar problems from happening again.

BGA PCB SMT patch assembly process

Design stage
In the PCB design stage, it is necessary to reasonably layout the position of the BGA package and the pin connection to ensure that the spacing between the pins is sufficient, and to avoid excessive density and increase the difficulty of soldering.
Preparations
Prepare the required BGA chips, SMD components, PCB boards, soldering equipment and soldering materials.

Feeding
Put BGA chips and SMD components on the designated position of the PCB board in the correct direction and position.
Paste
Apply an appropriate amount of solder glue on the PCB to fix the BGA chip and SMD components in the correct position.
Reflow Soldering
Send the assembled PCB board into the reflow soldering equipment, by controlling the temperature curve and time, the solder glue and the pad are melted, and the BGA chip and SMD components are firmly soldered to the PCB board.
Cooling
After the soldering is completed, take the PCB board out of the reflow soldering equipment and let it cool naturally.
Inspection
Use tools such as X-ray inspection to inspect the soldering quality to ensure that there are no soldering defects, such as virtual soldering, solder balls are not full, etc.
Cleaning
Clean the PCB board after soldering to remove residual soldering glue and impurities.
Testing
Conduct functional testing and performance testing to ensure that the assembled PCB board can work properly.
