| (4) Convection reflow soldering |
| Convection reflow soldering is an improved method that solves the problems of infrared reflow soldering, i.e. uneven temperatures of the PWB and SMDs. This method also solves the problem of vapor phase soldering (VPS)Note--high running cost. The principle of convection reflow is to heat the SMDs by convective heat transfer, i.e., by making heated air circulate in an oven. Consequently, even if the thermal capacity of the PWB differs from that of the SMDs, the temperatures of the PWB and SMDs become uniform after the lapse of a certain time. |
| The features are of the convection reflow soldering are described as follows. 1. Advantages
2. Disadvantages
