## Common ground
All options describe breadboards made from different solid materials, used for prototyping electronic circuits.
## Options at a glance
**3924.10 – Plastic**
- **Defining trait:** Made from synthetic polymer (e.g., ABS or polystyrene), lightweight and insulating.
- **Typical examples:** Standard DIY breadboards, hobbyist electronics kits.
- **Best fit when:** You need low cost, easy molding, and electrical insulation.
**4419 – Wood**
- **Defining trait:** Made from natural wood (e.g., plywood or hardwood), non-conductive but less durable.
- **Typical examples:** Handmade prototypes, artistic or vintage-style circuit boards.
- **Best fit when:** Aesthetic appeal or eco-friendly materials are prioritized over precision.
**6911.10 – Porcelain/China**
- **Defining trait:** Made from fired clay with high heat and electrical resistance.
- **Typical examples:** Industrial or lab-grade boards in harsh environments.
- **Best fit when:** High thermal stability and insulation are required.
**6912.00 – Ceramic**
- **Defining trait:** Made from advanced ceramic (e.g., alumina), extremely heat-resistant and durable.
- **Typical examples:** High-frequency or high-power circuit prototypes.
- **Best fit when:** Extreme temperature or mechanical stress is expected.
**7013.10,7013.4X – Glass**
- **Defining trait:** Transparent, non-conductive, and chemically inert.
- **Typical examples:** Lab displays, visible circuit layouts, educational tools.
- **Best fit when:** Visibility of wiring or a transparent surface is essential.
**7323.9X – Iron/Steel**
- **Defining trait:** Made from ferrous metal, conductive and strong but not insulating.
- **Typical examples:** Rare; only if used as a structural base with insulated inserts.
- **Best fit when:** Structural strength is key, but insulation must be added separately.
**7615.10 – Aluminium**
- **Defining trait:** Lightweight metal with good thermal conductivity and moderate electrical conductivity.
- **Typical examples:** Heat-dissipating prototypes or modular systems.
- **Best fit when:** Thermal management is critical, even if insulation requires extra design.
## Key differences
| Material | Insulating? | Thermal Stability | Durability | Visibility | Conductivity |
|--------------|-------------|-------------------|------------|------------|--------------|
| Plastic | Yes | Low | Medium | No | No |
| Wood | Yes | Medium | Low | No | No |
| Porcelain | Yes | High | High | No | No |
| Ceramic | Yes | Very High | Very High | No | No |
| Glass | Yes | Medium | Low | Yes | No |
| Iron/Steel | No | Medium | High | No | Yes |
| Aluminium | No | High | Medium | No | Yes |
## How to choose
- Is the board primarily for insulation and low cost? → 3924.10
- Do you need a natural, visible material or artistic look? → 4419
- Is heat resistance critical (e.g., high-power circuits)? → 6911.10 or 6912.00
- Do you want to see the wiring clearly? → 7013.10,7013.4X
- Is structural strength or thermal dissipation most important? → 7323.9X or 7615.10
## Overlaps & pitfalls
- Plastic (3924.10) and wood (4419) both insulate but differ in durability and cost.
- Glass (7013) and ceramics (6912) are both non-conductive and heat-resistant, but glass is fragile; choose based on mechanical needs.
- Iron/Steel and Aluminium conduct electricity—only suitable if insulation is added separately.
- **No priority rule given**—choose based on the product’s MAIN function: insulation vs. thermal management vs. visibility
