content: Looks interesting. It would be interesting to see mechanical strength figures. How it works with large BGA chips and thermal cycles etc."Furthermore, in 2018 Lenovo intends to offer the new procedure for use on an industry-wide basis free of charge."http://news.lenovo.com/news-releases/lenovo-announces-breakthrough-innovative-pc-manufacturing-process.htm

content: Didn't even think of that, another reason lead-free is terrible for the environment is that it requires more energy input, producing more CO2.The higher temperatures also produce more harmful compounds and particulates (if not properly filtered, ie hobbyist use).Sounds like a new alloy:QuoteMaybe we can have the best of both worlds at some point, low-temp lead-free solder. After their patent expires of course.

content: Risky introducing your own process, in regards to reliability, rework and availability of materials. Not just for the mfg. but also anyone who needs to do servicing.Tim

content: QuoteIt seems that it's been a long time since any major manufacturer cared about the (third party) serviceability of their machines.

content: Bismuth solder? Doesn't that usually put strength and fracture resistance right into the dumpster? I'm sure it'll last past the warranty period. Maybe not much longer.

content: Quote from: ConKbot on February 16, 2017, 06:29:32 amMy thoughts exactly. Even less reliable than lead-free, and all the talk of "savings" is going to be offset by the greater failure rate (which is exactly what they want --- force people to buy new hardware.)
