Needle core characteristics:
Soldering the core: 1. No special tools are required, just a soldering iron is enough
2. Especially suitable for very small and brittle cores
3. The core opening has a solder cup opening to allow the solder to flow sufficiently
Crimp core: 1. Practical and fast fixing of the core and operation outside the insulator
2. Can be used at relatively high temperatures
3. Need to buy special tools
4. In the process of crimping the core, there will be no insulation caused by welding.
5. High tensile strength
6. Completely complete lead-free solution
Board pin core: 1. Make the PCB board more secure and reliable
2. Reduce equipment damage to PCB damage
3. Realize signal transmission in dense space devices
