How about innovative plated crimp solutions for connectors in the automotive industry?

ONE. How are innovative plating crimp solutions for automotive industry connectors? One of the challenges of innovative plated crimp solutions for automotive connectors is that the use of lead-free materials leads to an increase in tin whiskers. These small fragments from electronic stylus pins pose a real problem of increased risk of electronic short circuits, making the automotive connector industry a special crimping challenge. As automakers put more electronics, connectors and sensors into vehicles at increasing densities, individual tin whiskers can pose a real risk of conducting electricity across unrelated systems, easily leading to costly and disruptive product failures or recalls. One of the automotive industry's innovative plated crimp solutions is the plated crimp, where crimped pins provide solderless (i.e., lead-free) terminal to lead-free terminal PCB connections, proving adequate for harsh environment automotive applications, available in both header and single-pin solutions. Metallurgists at most connector companies have also devised new techniques to coat these pins with lead-free materials instead of traditional tin/lead (SnPb) or tin (Sn) plating materials. Now plating pins with tin-free bismuth (Bi) compounds, a new process called LITESURF plating reduces the risk of whiskers by more than 1600 times, providing ideal products for automotive applications including airbag control units, anti-lock braking systems, electronic stability control systems, sensor systems and engine management systems. Innovative plating crimp solutions for automotive connectors eliminate soldering from the termination process materials offers many advantages, even significantly reducing thermal stress on the connector, reducing the overall use of hazardous materials, providing customers with better process control, and eliminating soldering errors such as flux residue and cold solder joints that have led to quality control issues in years past. However, many materials and plating processes are still challenged by tin whiskers due to the wide range of plating and under-plating options available for the crimp pins of automotive connectors. Bismuth-based plating offers material deposition similar to tin, but far less risk of whiskering, and is an economical, non-toxic metal that is critical to its long-term acceptance and application in electronic systems.
