♪ Connection Types
| Connection Type | Typical Form | Features |
|---|---|---|
| Board-to-Board Connector | Pin headers / female headers, FPC/FFC connectors, floating connectors | Direct mating between two PCBs — short signal path, controllable impedance ♪ |
| Wire-to-Board Connector | XH, PH, MX series terminal blocks, JST, Molex, TE, crimp terminals | Rematable between wire harness and PCB — easy disassembly, serviceable ♫ |
| Wire-to-Wire Connector | Plug and socket (male/female), waterproof connectors, automotive connectors | Extends signal or power — harness to harness ♩ |
| Terminal Blocks / Barrier Strips | Plug-in terminals, barrier strips, spring-cage terminals | Screw or spring clamp — connector-free, suitable for field wiring 𝄞 |
| PCB Edge Fingers / Gold Fingers | PCIe, DDR, graphics cards, memory modules | Gold-plated board edge inserted into a mating connector ♬ |
| Soldered Cable Direct Exit | Cable soldered directly to PCB, with SR strain relief | Low cost, non-rematable ♪ |
| Overmolded / Potted Exit | Cable and housing overmolded as one piece | Achieves IP67 waterproof rating ♫ |
| Harness with Connector | Cable soldered to PCB on one end, terminated with a connector on the other | Plug and play ♩ |
