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...]

IPC releases training DVDs on lead-free surface mount

18.09.2006 16:30 - Source: Lead-Free Zone Blog

The Association Connecting Electronic Industries (IPC) has release two training DVDs on lead-free surface mount, one that covers surface mount rework and another looking at surface mount assembly.

DVD-67C, Lead-free surface mount rework, explains the differences between lead-free and tin-lead solder – for solder joint touch up and rework. It covers component removal, land preparation, component replacement and approved methods for touch up and rework with demonstrations of point-to-point soldering, drag soldering and touch up joints with too little solder bridges.

DVD-68C describes how the conversion to lead-free production affects the surface mount assembly process, including solder paste application, verification of lead-free components and circuit boards, special precautions for moisture sensitive devices, the effects of higher soldering temperatures on reflow/wave soldering operations and requirements for post-solder cleaning.

Both of the training programs discuss why companies are making the switch to lead-free processes, the characteristics of lead-free solder allows and lead-free solder joint evaluation comparing target acceptable and unacceptable lead-free joints with their tin-lead counterparts.
