 Stencil fabrication is a process used in the PCB assembly process to apply a consistent and precise amount of solder paste to the PCB. The stencil is a thin sheet of metal or other material with openings the size and shape of the surface mount components on the PCB. The stencil is placed over the PCB and a thin layer of solder paste is applied over the stencil using a squeegee or other tool. The excess paste is then wiped away, leaving a thin layer of paste in the openings on the PCB. 

 Stencil fabrication is an important step in the PCB assembly process because it helps to ensure that the correct amount of solder paste is applied to the PCB, which is critical for creating reliable connections between the components and the PCB. The stencil also helps to ensure that the paste is applied consistently across the PCB, which is important for ensuring that all of the components are attached properly and that the PCB functions correctly. 

 Several factors can impact the quality of the stencil fabrication process in PCB assembly, including: 

•  Stencil thickness:  The viscosity, or thickness, of the paste, can affect how easily it can be applied through the stencil openings. 
•  Stencil material:   The material of the stencil impacts the durability and lifespan of the stencil, with some materials being more prone to wear or damage than others. 
•  Solder paste characteristics:  The particle size and composition of the paste can also impact the accuracy of the paste application and the reliability of the connections between the components and the PCB. 
•  Accuracy of stencil openings:  The accuracy of the stencil openings is also critical for ensuring a high-quality paste application. 

 Automated component assembly is a crucial step in the production of printed circuit board assembly (PCBA). It involves the use of component pick and place machines to accurately and efficiently place electronic components onto a PCB, ensuring that they are properly aligned and soldered in place.  A robotic arm is used to pick up individual components and place them onto the PCB in the correct location. 

 The component pick and place process typically begins with the creation of a component placement plan, which specifies the exact location and orientation of each component on the PCB. This plan is typically generated using computer-aided design (CAD) software and is based on the structure design  of the PCB. Once the component placement plan has been created, the component pick and place machine or robot is used to locate and pick up each component from a supply tray or tape reel.  The component is then placed onto the PCB in the correct location, using precise control and alignment to ensure that it is properly positioned. In some cases, the component may need to be rotated or flipped to achieve the correct orientation.  

 As a leading provider of PCBA services, FairyTek are committed to using the latest technologies and techniques in automated component assembly to ensure the highest quality and reliability of our products. Our state-of-the-art facilities and skilled technicians allow us to handle even the most complex and demanding projects with confidence and efficiency. 

 Quality control and inspection are essential steps in the production of printed circuit board assembly (PCBA) to ensure that the finished products meet the required standards for performance, reliability, and safety.  These processes involve the use of various testing and evaluation methods to identify and correct defects or deviations from specifications. 

•  Visual inspection: We exam the PCB and components with the naked eye or under magnification to identify any visible defects or issues, such as misaligned components, soldering defects, or damaged components. 
• AOI (Automated Optical Inspection): We use specialized cameras and software to automatically inspect the PCB and components for defects or issues.
•  ICT (In-Circuit Testing): We can use specialized equipment to test the electrical characteristics of the PCB and components while they are still in the circuit. 
•  Ultrasonic testing:  Ultrasonic testing involves the use of high-frequency sound waves to inspect the PCBA for defects or issues that may not be visible using other inspection methods. 
• X-ray inspection: We use X-ray technology to create an image of the inside of the PCBA, allowing defects or issues within the assembly to be identified. 

In FairyTek, X-ray inspection is particularly useful in PCBA production for identifying issues:

1. Soldering defects, including shorts, opens and bridging
2. Misaligned or improperly positioned components
3. Missing or broken components
4. Internal damage or defects in components

 Functional testing is typically done after the PCBA has been completed after the wave soldering process. It involves testing individual components as well as the entire assembly and using a variety of techniques and methods depending on the specific requirements of the PCBA. 

Some common techniques FairyTek used in functional testing include:

• Input/output testing: We test the PCBA's ability to accept input signals and provide output responses in accordance with the design specifications.
• Performance testing: We test the PCBA's performance under a variety of operating conditions to ensure that it meets the required specifications.
• Stress testing: We subject the PCBA to extreme operating conditions, such as high or low temperatures, to ensure that it is able to withstand the rigors of real-world use.

It is important to choose fixtures for functional testing that is capable of accurately and reliably holding and accessing the PCBA, and that can withstand the rigors of the testing process.  

Some common types of fixtures FairyTek support in functional testing of PCBAs include:

• Test jigs: These are simple fixtures that are used to hold the PCBA in place and provide access to the components and connections for testing. Test jigs may be manually operated or automated, depending on the specific needs of the testing process.
• Socket fixtures: These are fixtures that have sockets that are designed to hold specific types of components, such as integrated circuits (ICs). Socket fixtures allow components to be easily swapped in and out for testing without the need to rework the PCBA.
• Probes: These are specialized fixtures that are used to make electrical connections to specific points on the PCBA for testing purposes. Probes may be manually operated or automated and may be used to test specific components or connections on the PCB.

FairyTek can help customers prepare testing fixtures to offer local tests before PCBAs are shipped, for the purpose of quality insurance of final goods.
