In today's consumer electronics industry, both technologies are widely used, often appearing in the same device. For example, in an ultra-thin laptop, the main connection between the motherboard and screen might use direct gold-finger connectors for the sake of thinness, while the connections between the motherboard and components like the touchpad and keyboard might use traditional connectors. If reliability and maintainability are more important than saving a fraction of a millimeter in thickness, then connectors are a more reliable and mature choice. If you are building an ultra-thin, cost-sensitive new product with a high-precision automated production line, you should carefully consider the direct gold-finger connector solution.
