I am in Singapore for Semicon Singapore 2008. This is the first exhibition (that I can recall) that started on a Monday! It sure felt a...
Thermal Conductivity of a Metal Alloy, Scientifically Determined
Bob Jarrett gave an excellent explanation of the thermal conductivity of metal alloys and their relationship with electrical conductivity. It is as fo...
BGA Red Dye Penetrant Testing
Ok, so it happened again. Another urgent request was brought to me for action. This time it was a customer who had performed a Red Dye Penetration......

As an engineer in the semiconductor industry, there is always the possibility for you to travel to another country to troubleshoot a problem on a line...
Alloy Thermal Conductivity
Calculating the thermal conductivity of an alloy is not done by taking an average (or weighted average) of its elemental constituents. When two metals...
J-STD-004 Halide Test Requirements Update
The IPC J-STD-004 committee met at APEX last month. They are planning on releasing an updated specification. One positive change that is being made ...
Intermetallic Growth
Time is precious, and some alloys take their precious time to form intermetallics. For lower melting point alloys, quick wetting doesn’t mean an...
Thermal Interface Materials for Other Extreme Conditions
The typical extreme device needs an advanced thermal interface material to keep the interface cool while the device generates extreme amounts of heat....
