What’s Flying Probe Testing?
Flying Probe Testing (FPT) is a type of automated electrical testing used to check the functionality and integrity of Printed Circuit Boards (PCBs). Instead of using a bed-of-nails fixture (a traditional testing method), flying probe testers use multiple probes that move across the PCB to make contact with test points, component leads, or vias. These […]
What are SMD Components?
SMD components (Surface Mount Device components) are small electronic components designed to be mounted directly onto the surface of a PCB (Printed Circuit Board) without the need for leaded connections that pass through holes in the board. These components are integral to Surface Mount Technology (SMT), a highly efficient method used in modern electronics manufacturing. […]
How thick is flex PCB dielectric?
The dielectric thickness of a flex PCB (Flexible Printed Circuit Board) is a critical factor that directly influences its mechanical flexibility, electrical performance, and heat dissipation capabilities. Understanding how thick a flex PCB’s dielectric layer should be is essential for optimizing the design to meet specific application needs. What is the Standard Dielectric Materials in […]
What are the PCB materials?
When it comes to PCB (Printed Circuit Board) materials, choosing the right ones is crucial for optimizing performance, reliability, and cost. The materials used in PCBs must offer the right combination of mechanical stability, electrical insulation, thermal conductivity, and chemical resistance to ensure the board can handle the demands of various applications. 1. Base Materials […]
What is the trace width of a flex PCB?
The trace width of a flex PCB refers to the width of the conductive paths (usually made of copper) that carry electrical signals across the board. Trace width is an important parameter in flex PCB design because it affects the board’s electrical performance, mechanical flexibility, and heat dissipation. How to Determine the Trace Width? 1 […]
What is PCB Manufacturing Process?
The PCB manufacturing process involves multiple steps to turn a design into a fully functional Printed Circuit Board (PCB). Here is a step-by-step overview of the process: 1. Design and Output 2. Printing the PCB Design 3. Etching 4. Layer Alignment and Lamination 5. Drilling 6. Plating 7. Solder Mask Application 8. Surface Finish 9. […]
What is the adhesive in flex PCB?
In flex PCBs (Flexible Printed Circuit Boards), adhesive layers are crucial for bonding the conductive copper layers to the flexible insulating substrate, which is typically made of polyimide or another flexible material. These adhesives provide mechanical stability while allowing the board to bend and flex without compromising performance. The Common Types of Adhesives Used in […]
What is the maximum layers in flex PCB?
What is the maximum layers in flex PCB? The maximum number of layers in a flex PCB (Flexible Printed Circuit Board) can vary depending on the complexity of the design, material properties, and manufacturing capabilities. Typically, flex PCBs are available in configurations ranging from single-layer to multi-layer. Standard Layer Configurations: 1.Single-Layer Flex PCB: This is […]
The advantages and disadvantage of tent via, plugged via, and vias not covered?
The advantages and disadvantage of tent via, plugged via, and vias not covered? When deciding between tented vias, plugged vias, and vias not covered in PCB design, it’s essential to understand the advantages and disadvantages of each type based on factors like protection, cost, and the specific needs of the circuit. Here’s a comparison of […]
