In all fairness no one has the answer for you, non of the lead-free alloys has been long enough in use or have supporting long-term reliability data. No matter what alloy you will use, your company will be at risk, that�s why so many exemptions are a

Steve, You're asking the right questions, don�t listen to sales pitch and stick with the facts. But you're in for a tough ride with lead-free because there is just not enough data and experience with the lead-free alloys as of yet. Every month you h

One of our customers' products has a couple of adjacent 0603 packages (one resistor, one cap) that are .010" apart. They are side by side, not end to end. The adjacent pads between the two parts are electrically connected so bridging isn't an issu

Hi Rob, Don't feel sorry I like these discussions make us think more thorough. This is the supporting scientific paper they used in support of the exemption request. Effects of lead on tin whisker elimination By Wan Zhang and Felix Schwager. http:

Hi Pat, The main driver for the UK on Lead-Free is to avoid leachate in our drinking water & in the food chain. Whilst John Burke's report is compelling & I agree with him on the points he has raised, regarding the leachate issue he has referenced

Howdy aj, wow! Be prepared for serious problems with corrosion of your stainless steel workings of your pump. Last I looked changing a wave solder pot over to nitrated coating for electrovert was in the neighborhood of 18-20K. I'm not a betting man

smt You should have no issue using your exsisting oven for both leaded and lead free materials if the machine is capable of delivering the desired profiles. One aspect that makes a "lead free" oven is the design of the system. Ability to reach th

Hypothesis #1: We agree with Steve. You are probably seeing the nickel underplate. The gold was absorbed into the solder in portions of a second, so that you don't see it is not surprising. We're guessing that the gold was porous and allowed the n

Hi, We are about to change our wave over to lead free solder, and it's a Soltec Deltawave, which uses about 750 KG of solder. Our supplier is recommending we change the bath over, however that seems a bit extreme. They are concerned we won't get ri

Hi, The bath is titanium coated, and the machine is only 2 years old, and was designed for lead free, so we know we don't need to change anything. The reason the supplier gave for suggesting the bath change is "other companies are doing it" and it'
