Great, just what we need - Psuedo science. To paraphrase: We tried 99.5Sn/0.5Cu & it didn't work so we couldn't be bothered to try any other lead free alloy. So give us an exemption else we'll bury you up to the neck in the stuff. I have no probl

Dr. Lee, For lead-free wave soldering, we are recommended to use SnCu0.7, why not 0.8 or more ?? Since SnCu0.7 has eutectic melting point at 227 deg C, does it mean with more Cu or less Cu, the melting point will be higher ?? Also, in lead solderin

We would like to start testing our lead free wave solder machines in house. Mostly looking for lead and copper content. Malcom makes a relatively inexpensive machine that does this (STA-1 http://www.malcomtech.com/products_sta1.html). Does anyone

To take our turn at keeping everyone else on the straight and narrow. For more on lead contamination of no-lead solder, look here: http://www.aimsolder.com/techarticles/Lead%20Contamination%20in%20Lead-Free%20Electronics%20Assembly.pdf [We apolog

CMiller, Thanks for the valuable info! We are in the midst of lead-free deployment and need to know good alloy choices at both wave and ERSA. I have heard the same things regarding SAC305's price for bar solder, but don't yet know what the process

The fluxes involved with lead-free soldering tend to be more aggressive and the tip deterioration is a side effect of making the world a greener place. I am not certain if any of the tip manufacturers claim to have lead-free resistant tips. I would

In passives I dont know if anything changed at all other than the terminal plating. As for Active components there has been much engineering done to allow for the extra heat needed to liquify say SAC305 or other lead free pastes without damage to th

Hi, The tin flush is a good idea, and better than the suppliers suggestion of filling with lead-free solder which is much more expensive. I guess we won't be leaving a KG of solder in the bath, but based on your experience, how much remaining sold

ok, sorry ,750 was deg F and which I said 350~400 were deg C, I got a mistake. As I know, we use 660~720 deg F to do reworking for lead free solders such as SAC series and SnCu0.7 series solder to protect irons and components on boards. when temp.

Dave, that's good thread, but I think Mike is more concerned with the Titanium inserts that pallet manufacturers often use to overcome sh*tty designs - like the ones where they put a Through-hole 2mm away from a SMT pad. He's not so concerned about t
