Presentation Transcript

  1. Tube-to-Chip soldering Georg Nüßle

  2. Paper Following the recipe from: “Solder-based chip-to-tube and chip-to-chip packaging for microfluidic devices” Edward R. Murphy et al., The Royal Society of Chemistry, 2007 µcool weekly

  3. Soldering to PCB • Tube 1/16” stainless steel, Swagelok ferrule: big part stainless steel, small part brass • Was successful, no solder around at the tube µcool weekly

  4. Soldering to Chip with Goldlayer • Chip: 100µm Si with 20nm Ti and 200nm Au • Was successful too • Reinforcement for pressure test, chip was glued on thick Si piece µcool weekly

  5. Pressure Test • NanoPort/steel tube combination failed at 78 bar • Test object was ejected, which led to a brake off of the Si chip from the reinforcement • Si part under the the soldering seemed to be intact • Second pressure test, Si chip breaks at 37 bar, solder is unharmed, no solder in tube µcool weekly

  6. Outlook Test soldering with microfluidic device and prove that the tube is not blocked by solder. µcool weekly
