Raspberry Pi's Soldering Secret: 60 Million Units and a Refine Process
2025-04-30

Early Raspberry Pi production relied on a mix of manual and robotic through-hole soldering, especially for components like the 40-pin GPIO header, Ethernet, and USB ports. This proved inefficient and costly. To overcome this, Raspberry Pi partnered with Sony to implement an innovative lead-free reflow soldering process that simultaneously solders surface-mount and through-hole components. This significantly improved efficiency and product quality, leading to the production of over 60 million units.
