Chess, I agree with the author. Lead/Tin based

Chess,

I agree with the author. Lead/Tin based solders on printed circuit boards can be handled appropriately. The previously established limit for "Cadmium" was 10 times less than Lead and at the same limit for Mercury. The "EU" went back with the latest data in hand, was writing a new standard for adoption of"ZERO CADMIUM" due to other manufacturers had developed products performing the same functionality that were now " CADMIUM FREE" and readily available. So now it comes down to the protection of "Jobs" within the EU community....If the RoHS limit was going to stay the same, we would have already heard about it. IMHO, the Cadmium limit has been reduced to "ZERO". Another "Wrench in the Program" was the BREXIT VOTE"...The EU rely's heavily on trade with the UK and the US. British Parliment was already on record with a vote to "Eliminate All CADMIUM" from any source. So, There really lies the rub. China/Asia and the USA are fully on board with being "CADMIUM FREE" .
Quantum Material's has raised the "BAR" with their 500 Degree and Cadmium Free Red, Green, Blue Quantum Dots for the "DISPLAY'S OF THE FUTURE". All of the "Other Suppliers" and End Users are in a "Scramble Mode" to get their products out there. They are not Panicked yet. APPLE has announced all of their Displays will be Quantum Dot Based beginning 2018. It is something to look forward to.

I am still looking for news on the 35 "NDA'S" that we have not had closure on. Perhaps we shall see more "Revenue" reported before then.

THERE IS ONLY ONE WAY.....IT'S CADMIUM FREE

RoHS Restricted Substances

RoHS specifies maximum levels for the following six restricted materials:

Lead (Pb): < 1000 ppm
Lead is commonly used in the electrical and electronics industry in solder, lead-acid batteries, electronic components, cable sheathing and in the glass of cathode-ray tubes.

Mercury (Hg): < 100 ppm
Mercury is widely used metals in the production of electrical and electronic appliances and is concentrated in batteries, switches and thermostats, and fluorescent lamps.

Cadmium (Cd): < 100 ppm
Cadmium is used in electronic equipment, car batteries, and pigments.

Hexavalent Chromium (Cr VI) < 1000 ppm
While some forms of chromium are non-toxic, Chromium VI can produce toxic effects.

Polybrominated Biphenyls (PBB): 1000 ppm
These are flame retardants found in electronic and electrical appliances. They have been found in indoor dust and air through evaporation from plastics.

Polybrominated Diphenyl Ethers (PBDE): < 1000 ppm
These are also flame retardants found in electronic and electrical appliances. Combustion of printed wiring boards release toxic emissions.

Bis(2-Ethylhexyl) phthalate (DEHP): < 1000 ppm
These are used to soften PVC and vinyl insulation on electrical wires.

Benzyl butyl phthalate (BBP): < 1000 ppm
These are used to soften PVC and vinyl insulation on electrical wires.

Dibutyl phthalate (DBP): < 1000 ppm
These are used to soften PVC and vinyl insulation on electrical wires.

Diisobutyl phthalate (DIBP): < 1000 ppm
These are used to soften PVC and vinyl insulation on electrical wires.


Those were the old limits for RoHS Compliance.
