General PCB Questions
A Printed Circuit Board (PCB) is a flat board that mechanically supports and electrically connects electronic components using conductive pathways, tracks, or signal traces etched from copper sheets laminated onto a non-conductive substrate. PCBs are the backbone of almost all electronic devices, from simple gadgets to complex industrial systems.
At Benlida, we manufacture a wide range of PCBs to meet various application needs:
- Single-Layer PCBs: A basic PCB with one layer of conductive material, suitable for simple electronic devices.
- Multi-Layer PCBs: Consist of two or more layers of conductive material separated by insulation, ideal for complex circuits requiring high density.
- Flexible PCBs (Flex PCBs): Made of flexible substrates that can bend or fold, used in compact or dynamic electronic devices.
- Rigid-Flex PCBs: A combination of rigid and flexible layers, offering both mechanical stability and flexibility.
- HDI PCBs (High-Density Interconnect): Advanced boards with finer lines and spaces, blind/buried vias, and high component density for high-performance applications.
We use high-quality materials to ensure performance and durability:
- FR-4: Standard flame-retardant epoxy laminate, widely used in general electronics.
- Rogers: High-frequency material for RF/microwave applications.
- Aluminum: Provides excellent thermal dissipation, ideal for LED and power electronics.
- Other specialized substrates: Available upon request for high-performance or industrial applications
- Thickness: Common PCB thicknesses range from 0.4 mm to 3.2 mm, depending on application requirements.
- Size: Standard board sizes typically range from 50 mm × 50 mm up to 500 mm × 500 mm, but custom sizes can be fabricated to meet specific design needs.
- Single-layer PCBs: Have only one conductive layer and are suitable for simple circuits. They are easier and cheaper to manufacture but have limited functionality.
- Multi-layer PCBs: Consist of two or more conductive layers separated by insulating materials. They allow higher circuit density, complex designs, and improved performance for advanced electronics.
Choosing the right PCB depends on your project requirements:
- Complexity of the circuit: Multi-layer or HDI PCBs for high-density designs.
- Mechanical requirements: Flexible or rigid-flex PCBs for dynamic or compact applications.
- Thermal performance: Aluminum or high-TG FR-4 for heat dissipation.
- Electrical performance: Consider materials like Rogers for high-frequency or RF circuits.
Our engineers can provide guidance to help you select the most suitable PCB type for your application.
PCB Fabrication Questions
Our PCB manufacturing process ensures high precision and reliability from design to final product:
- Design Review: We first analyze your submitted design files for manufacturability and optimization.
- Material Selection: Based on your requirements, we choose the appropriate substrate material (FR-4, Rogers, aluminum, etc.).
- Lamination & Copper Cladding: Layers of the PCB are laminated together and copper sheets are applied.
- Photoengraving & Etching: Circuit patterns are transferred to the copper layers and excess copper is etched away.
- Drilling: Holes and vias are drilled with high precision.
- Plating & Coating: Copper plating, solder mask application, and surface finishes (HASL, ENIG, OSP, etc.) are applied.
- Electrical Testing & Quality Inspection: Each PCB is tested for short circuits, continuity, and overall quality.
- Final Delivery: Boards are cut to size, cleaned, and prepared for shipping.
We accept the most common and industry-standard PCB design files to ensure smooth production:
- Gerber files (RS-274X) – standard format for PCB fabrication.
- ODB++ – comprehensive format including fabrication and assembly data.
- IPC-2581 – modern standard for design transfer.

PCB Assembly Questions
PCB Assembly (PCBA) is the process of mounting and soldering electronic components onto a printed circuit board (PCB) to create a fully functional electronic device. This process can include surface-mount technology (SMT), through-hole assembly, or a combination of both, depending on design requirements.
Benlida provides a comprehensive range of PCB assembly services:
