软硬结合板/刚挠结合板
软硬结合板有哪些可用的结构？
软硬结合板有多种不同结构可供选择，以下是常见的几种：
传统软硬结合构造（IPC-6013 4型），包含有镀通孔的三层或多层软板。最高支持22L硬板带10L软板结构。
不对称软硬结合构造，包含有镀通孔的三层或多层软板，且软板位于硬板一侧。
多层软硬结合构造，埋孔/盲孔（微孔）作为硬板结构的一部分，支持两层微孔，可能可能还包含两个硬板结构作为同质结构的一部分。

Rigid-Flex PCBs – Technical specification
| Feature | NCAB´s technical specification for Rigid flex PCBs |
| Number of layers | 4-16 layers |
| Technology highlights | Mixed materials including RF and high speed, standard FR-4, polyimide flex. Adhesiveless or adhesive based polyimide flex constructions, with cover coat or flexible solder mask materials. |
| Bending performance | Based on the specific design, the bend performance can range from a basic 90 °bend to fit to a full dynamic flex with 360° range of motion in the flex tail that will withstand continuous cycles throughout the product life. |
| Bend features | Bend radius controls the flexibility of the flex portion of the board. The thinner the material the lower the bend radius and the more flexible the flex section. |
| Materials | RA copper, HTE copper, FR-4, polyimide, adhesive |
| Copper weights (finished) | ½ ounce, 1 ounce, 2 ounce, 3 ounce |
| Minimum track and gap | 0.075mm / 0.075mm |
| PCB thickness | 0.4mm to 3mm |
| PCB thickness in flex section | 0.05mm to 0.8mm |
| Maxmimum dimensions | 457mm to 610mm |
| Surface finishes available | ENIG, OSP Immersion tin, Immersion silver |
| Minimum mechanical drill | 0.20mm |
| Minimum laser drill | 0.10mm standard, 0.075mm advanced |
