I think of palladium coated copper with gold flash (CuPdAu) as bond wire used in chip attach. Look here: https://www.heraeus.com/media/media/het/doc_het/products_and_solutions_het_documents/bonding_wires_documents/fact_sheets/Factsheet_PdFlash.pdf

Dave, thanks. I was going to change Cu/PD/Au to Ni/Pd/Au and then my question is: Has anyone had soldering issue with components (ICs) with the above finish during reflow and/or had to change the oven profile to improve the wetting. Sorry for confusi

Unfortunately, I can't give any help but wanted to ask about your experience with the 740 machine? How reliable has it been for you? Would you buy another or upgrade to newer machine? I just bought 2 pm570s arriving tomorrow. If they work out wel

Is the nozzle in good condition? If it is not flat because of damage or wear, it might loose vacuum and the part may have a tendency to shift. I don't have experience with these machines but how do you know the spindle is spinning slower when the co

After doing more research I have decided against Essemtec. Still liking the Europlacer iineo+. I also have been doing research on the Ipulse S20. I really want a minimum board width of 20". Fuji also has a nice looking system that will fit the bill

Sounds like you are sorted then. Always liked Fuji kit, had it in previous companies. I'd also take a look at the software tools they are bundling in before signing, unless you have Valor, Unicam, Aegis or similar already to handle the programs, opt

Get them to > quote individual feeder and nozzle prices too so > you know what you are committed to going forward. Amen to that, I took the phrase very affordable wrt essemtec nozzles and bits at face value until I came to want some more, and OMG

well, we have narrowed it down to the 12 nozzle Yamaha S20, the Fuji Aimex 3 and the Juki RS1. Waiting for the final quote from Fuji now. The Juki and Yamaha are within 10% of each other. It seems features and speed go to Yamaha between Juki and Yama

I must say so far the yamaha seems to fit the bill. Most of our products are low mix. Less than 6 different components per board. 90% are only 2 lol. So just looking at how the yamaha operates it seems gang picking the same part off 12 feeders seems
