| Video Discription | Immersion Gold of PCB board ENIG only is a thick nickel gold alloy with excellent electrical properties on the copper surface and can protect PCB for a long time and acts as a rust barrier, which can be useful and achieve good electrical performance in the long term use of PCB. What’s more, it also has environmental tolerance than other surface treatment processes do not. Nickel plating is because gold and copper diffuse to each other, and the nickel layer can prevent the diffusion between them. Without the nickel layer, gold will spread to the copper within hours. Another benefit of electroless nickel/impregnation is the strength of nickel, which is only 5um thick to control Z expansion at high temperatures. Besides, electroless nickel/gold plating can also prevent copper from dissolving, which will be beneficial for lead-free welding. Website: www.camtechcircuits.com |
