All You Wanted to Know About Computer Recycling

Computer recycling means saving some the parts from the obsolete computers while getting rid of those parts that are toxic in nature. This means that there must be a proper way to recycle the old and obsolete computers, so that we can get rid of them without putting ourselves as well as the environment to harm. [Read more...]

Tin, silver, copper becomes standard for RoHS solder

05.05.2009 06:30 - Source: Lead-Free Zone Blog

According to an article by Mitch Holtzer of Cookson Electronics that appeared in SMT Online, tin/silver/copper (SAC) alloys have become the industry standard lead-free solders since RoHS went into effect. Holtzer notes that “technical and economic factors are reducing the silver content in SAC compositions, with disadvantages like slower wetting speeds, and advantages like minimized BGA voids.” He also points out that “solder choices are influenced by the desired results, cost, BOM, and other factors.”
