Abstract :
The use of low-power lasers as an energy source for the purposes of soldering has many advantages. With limited laser power, the creation of a successful solder joint is strongly dependent on controlling and identifying any heat losses. The combination of experimental and theoretical work has identified the importance of: (1) substrate properties: in particular, changing the thermal conductivity can lead to substantial differences in the melting characteristics; (2) the layout of copper tracking: the enhanced sink effect can be very deleterious; and (3) accurate modelling of heat losses to the environment in any theoretical analysis
