Tiny 'tin whiskers' imperil electronics

Interesting article on why consumer grade electronics may fail in the future.

Better shop for MilSpec, if you want your technology to survive.

Interesting. Near the end of the article, it's mentioned that a tin-silver-copper solder might be what replaces tin-lead solder.

They also note that many types of electronics are exempt from the law, including military and other national security equipment, medical devices, and servers, data storage computers and telecommunications gear that use leaded solders.

Exemptions are also granted when alternatives to the hazardous materials don't exist yet, or because the substances can't be replaced without jeopardizing safety.

I'm seriously considering using companies that deal with government contracts.

Here is a hardy laptop made by General Dynamics:

Although it is very expensive for the new ones, you can always check out ebay for the prior models. A lot of these can be had though lease-back sellers.

Re: Tiny 'tin whiskers' imperil electronics

This is the RoHs compliance.

It�s another way to kill the US small business. ISO9000�..CE marking�.TUV approval��now RoHs compliance.

In order to sell your product into europe, you must be CE marked. TUV safety approvals are necessary also. Big business has the money to do the mark. It�s very expensive for a small outfit. For instance, for me to get a CE certificate on one of my electronic products, it costs me around $12,000�..and that�s if nothing has to get changed. It deals with emissions and susceptability issues. It makes your products expensive.

Now they want everyone to be RoHs compliant. It makes everything more expensive to produce. It also makes a lot of inventory useless to that market. It may even make it necessary to go through the marking certificate process again on your products, because of re-design issues.

They say I can�t sell a product (containing circuit boards�..switches�..chassis�.wire harnesses��paint�..plating�..etc.) with any lead in it. All components must be Rohs compliant��.to protect the environment. �They� don�t want my stuff hitting a land fill in 20 years��..to protect the children��..bullshit.

You know what has an exemption?......car batteries.

That make any sense?

Lead, however, is a serious health concern. In children, it can cause learning or behavioral problems......

But we�ll put murcury in their vaccines�.....that's OK.
