# Crimp vs Solder vs Screw vs IDC: Choosing a Termination Method - Published: 2026-10-26 - Author: Intorfilters team - URL: https://intorfilters.com/crimp-vs-solder-vs-screw-termination/ > Reliability, speed, tooling cost and field serviceability of the four main ways to attach wire to a connector. Key points - Crimp is the standard for production harnesses: fast, repeatable and vibration-resistant. - Solder suits PCBs and small batches but makes wire stiff at the joint. - Screw, spring and lever clamps allow tool-free field wiring. | Method | Strengths | Watch out for | | --- | --- | --- | | Crimp | Fast, gas-tight, vibration-proof | Needs the right die and wire size | | Solder | Low tooling cost, good for PCBs | Wicking, heat damage, slow | | Screw / spring / lever clamp | Tool-free, reusable, field wiring | Torque and ferrules for fine strands | | IDC | Terminates many wires in one press | Needs matching cable and insulation | | Press-fit | Solderless PCB mounting | Requires exact hole tolerance | ## Crimp [Crimp terminals](https://intorfilters.com/connectors/terminal-blocks/crimp-terminals-lugs-splices/) and [connector contacts](https://intorfilters.com/connectors/contacts-housings-accessories/connector-contacts-pins/) form a cold weld with the strands. More on [Wikipedia’s crimp page](https://en.wikipedia.org/wiki/Crimp_(electrical)). ## Screw, spring and lever [Terminal blocks](https://intorfilters.com/connectors/terminal-blocks/screw-spring-lever-terminal-blocks/) and [DIN-rail blocks](https://intorfilters.com/connectors/terminal-blocks/din-rail-terminal-blocks/) dominate control cabinets. Use ferrules on fine-stranded wire. ## IDC [IDC connectors](https://intorfilters.com/connectors/wire-to-board-connectors/wire-to-wire-idc-connectors/) terminate flat ribbon cable in seconds — ideal for internal board links.

For stranded wire under vibration, a correct crimp is usually more reliable because solder wicking creates a stiff point where strands can break. ### Do I need special crimp tools? Yes. Each terminal family has its own die profile; generic pliers give inconsistent crimps. ### Find these products in our catalog [Connector Contacts & Mating Pins](https://intorfilters.com/connectors/contacts-housings-accessories/connector-contacts-pins/) · [Screw, Spring & Lever Terminal Blocks](https://intorfilters.com/connectors/terminal-blocks/screw-spring-lever-terminal-blocks/) · [Wire-to-Wire & IDC Connectors](https://intorfilters.com/connectors/wire-to-board-connectors/wire-to-wire-idc-connectors/) [Request a quote or sample](https://intorfilters.com/request-quote/) ## Contact & ordering - Request a quote: https://intorfilters.com/request-quote/ - E-mail: info@intorfilters.com - Product catalog: https://intorfilters.com/products.md - Site guide for AI assistants: https://intorfilters.com/llms.txt
