Greener electronics

Because of the lower melting point of lead, it is largely used in solders, and this specialty made it very easy to work with. If the lead levels are to be reduced, new dorms of solder must be used but there is a problem that they all melt at higher temperatures. This results in a new need for manufacturers such as new manufacturing machines so that they could operate it at higher temperatures. In the same manner the PCB circuit boards that the chips are installed on need to be redesigned to withstand the higher temperatures. All of these changes will require investment in manufacturing and materials. Early on, much of these costs will likely be included into the price of the end product. Though over time, these costs will eventually drop, as the techniques and materials become more common. As we could expect, from greener electronics, consumers will benefit in the end. It is likely that most manufacturers will just enable all techniques and procedures for their entire product lines to conform with the RoHS directive because most companies try and leverage mass production benefits to costs As a result of these we could expect that the market will likely start to see more and more products that contain fewer hazardous chemicals. Nowadays as we can see, some of these products are already starting to make it to the US market. The experts say that the deadline is in a short time frame and as a result of this may of the early products that meet the rohs and weee guidelines will probably end up in European markets.

As we all know the major threat that we all face in the current information technology revolution is the disposal of e waste. It is a complex question we need to deal with such as how we could dump the e waste safely and avoid the hazardous after effects it cause in human health and environment. What is happening is that there are a large amount of hazardous materials contained in consumer electronics and computers that have typically been disposed of with normal trash. It is pointed out by scientists that materials such as lead used in monitor tubes and solder, mercury and other materials can leach out of the electronics in landfills and pollute water supplies. In order to avoid such disasters a number of governments are looking at various ways to remove these materials through recycling and other programs. The governments in Europe, after much effort, have gone even further than trying to prevent old electronics from ending up in landfills. As a preventive method, they have put together the RoHS directive in order to mandate what electronics can be sold within the continent. This directive was put into effect on July 1st, 2006 and it is quiet satisfying that it has brad implications for consumer electronics as a whole. According to this directive, in the manufacture of various types of electronic and electrical equipments, six hazardous materials are restricted to use. Also, there is another related directive such as the waste electrical and electronic equipment directive or WEEE. Both RoHS and WEEE directives are closely linked.
