Continuing the Lasky TechNet Counterpoint...and the Beat Goes On
Wednesday, August 17, 2011 | Harvey Miller, FabFile Online

A couple of weeks ago, the article below appeared in SMTonline, based in part on a very busy thread in IPC's TechNet.

Dr. Lasky's Lead-Free Solder Interview Stirs Up Heated TechNet Counterpoint

Dr. Lasky then supplied a statement specially to SMTonline. It is an expansion of a similar TechNet response to his critics.

Now we shall hear from some TechNet responders to Dr. Ron's TechNet response--edited and selected (there are so many!). You'll see my comments/responses below in red.

Correct indeed. When deaths from tin whiskers have been documented, the world press will jump on this fiasco like sharks to chum in the water. Then we can sit back and enjoy watching those imbeciles in Brussels try to explain their faulty logic.

Of course the cellphone industry could have used SAC solder on tin/lead plated terminations any time they wanted to. Lasky's Motorola argument is specious.

Note also that he never rebutted my comments re: tin whiskers. Totally ignored them. Tin whiskers are real, they happen randomly and they have the potential to kill people, will fill landfills with products that prematurely fail.

Look at the world's economy today. Who can afford to replace consumer electronics every few years? I'm not speaking about cellphones or tablets, I'm speaking about washers, dryers, large screen TVs, automobiles, general aviation airplanes, pleasure boat radars, the electric "smart" grid (billions of devices expected to be sold and have 20 year lifetimes), etc... Electronics is invading all consumer space, from your coffee pot to your toothbrush (and some toilets such as the Japanese Toto brand with heated seat and a bidet for $2,500).

I have an electric utility client who was going to do automated meter reading (AMR) to replace mechanical watt-hour meters, but that project has been deferred because of the bad economy. When I told him about tin whiskers he said he would write into the future specs that they must be made with tin/lead technology as they were going to AMR to make the meters last LONGER, reduce SERVICE calls! Not to increase them!
