| Some applications, including Quantum Computers, perform better at cryogenic temperatures, below what is known as the superconductivity point. This is because electrical resistance drops to zero when certain materials become superconductive, allowing current to flow without energy loss. Our series of cryogenic solder columns are made of specific materials that perform reliably at cryogenic temperatures for deep space and Lunar landings. Cryogenic solder columns reduce stress and strain caused by CTE mismatch when connecting large chip modules to PC Boards. In addition, materials can withstand fracturing caused by ductile to brittle transistion temperatures (DBTT) at extremely low temperatures. Next Generation solder columns. TopLine offers a wide range solder columns to meet your cryogenic needs. The tables below are just a small example of the column sizes we offer. Contact TopLine to discuss your specific needs. |

| With Lead (Pb) and Lead-Free Columns (RoHS) |
| Braided columns are available with Lead for Aerospace & Defense applications or Lead Free for RoHS AI Datacenters. Columns replace solder balls on ceramic substrates and Organic chip packages. |
| |
Why Columns? |
| Braided Solder Columns are non-collapsible, robust and compliant structures. Use for reducing stress caused by CTE mismatch. Columns are more reliable that solder balls when connecting large size chip packages to PC Boards operating in cryogenic environments. CTE mismatch (Coefficient of Thermal Expansion) puts stress on the interconnections over wide temperature cycles. The CTE of a ceramic alumina Al2O3 IC package is about 6.7ppm/°C. The CTE of organic copper clad boards is more than 17.5ppm/°C. Therefore, the amount of CTE mismatch between ceramic materials and organic boards is roughly 10ppm/°C. The corners of a large 50x50mm ceramic package might twist as much as ±70µm (±2.7mils) over temperature swings of 100°C. Eventually, the connections between the chip package and board will break over time. Solder columns are compliant and absorb CTE mismatch, thereby lengthening the life of the system. |
