Soldering Reflow Profile

The soldering reflow profile has to be created to a component according to component density, size, weight, colour and substrate type as these are main factors which determine heat convection rate through the layers of silicon. As the component been exposed to environment the original manufacturing profile cannot be used as it could be too aggressive and damage the board to the state of BER. Component data sheets and solder paste type used during manufacturing specifications are acquired to determine the peak melting point, which profile will be based upon. Typical de-soldering profile involves preheating, soak, reflow and cooling stages. Typical preheat stage is a ramp up of heat at around 3C/s up to 120 – 150C, depending on the solder alloy used. This stage ensures no heat shock damage occurs to the all substrates and expansion rates across the board are kept at similar ratio. During soak stage the temperature is ramped up to reach 170 – 210C in targeted area. Maintaining steep profile curve at this stage will allow to keep the profile short maintaining less than 5 minute total heat cycle. Liquidus stage 190C – 230C is crucial and we keep it as short as possible to prevent solder mask damage on component during automated vacuum powered lift. The last cool-down stage temperature curve is typically 5-6C/s to bring component back to environment temperature efficiently and without shock.

 

BGA IC Replacement

By far the most successful process available to recover printed circuit board with BGA failures. However, this process is the most expensive and cannot be applied to obsolete or EOL components. During this process old component has be removed, PCB BGA site cleaned and new component soldered in place. High success rate depends on quality of parts provided by supplier and information available, such as alloy type.
