CHAPTER 1 SOLDERING GENERAL


1.2 Soldering Process Flow

There are six types of soldering process flows, divided between single-sided soldering and double-sided soldering.

• Single-sided soldering

(1) Flow (Wave) soldering of THD
(2) Flow (Wave) soldering of SMD
(3) Reflow soldering


• Double-sided soldering

(1) Reflow soldering + Flow (Wave) soldering
(2) Reflow soldering + Reflow soldering
(3) Flow (Wave) soldering

The following sections give basic outlines of the respective processing flows.
When using a mixture of mounting methods, select the most suitable processing flow, taking into consideration the device's thermal resistance characteristics.
