Product type
HDI PCBs, or High-Density Interconnect Printed Circuit Boards, are advanced circuit boards that feature a higher wiring density than traditional PCBs. They are typically made from materials like FR-4, a flame-retardant epoxy resin, or other high-performance substrates. HDI technology allows for finer traces and smaller vias, enabling the placement of more components in a compact area, which is essential for modern electronic devices.
| Layer count | Typically 4 to 20 layers |
| Minimum trace width | 3 mil to 5 mil |
| Minimum via size | 0.2 mm to 0.3 mm |
| Material types | FR-4, Rogers, and other high-frequency materials |
| Surface finish options | HASL, ENIG, OSP |
| Impedance control | Typically ±10% or ±15% |
When selecting HDI PCBs, consider the layer count and the complexity of the design, as this will affect manufacturing costs and lead times. Specify the required trace widths and via sizes based on your circuit design. It's also important to discuss material types, such as FR-4 or high-frequency substrates, and surface finish options. Be clear about the quantities needed and any specific certifications required for your industry.
