When to Choose Gold Products

Higher yields and cost per unit make gold a viable option for many applications, even though the initial cost is more than alternative solders. A low oxygen atmosphere may be required if the application is flux free. In some instances, pressure is required to promote strong, void-free reflow on horizontal services.
