    • Wired parts often cause a problem during overhead transport of a fitted printed circuit board, being able to fall out of the through bores because said wired parts are not glued or fastened to the printed board by means of retaining clips or snap-in devices. The invention solves said problem by means of a printed circuit board and a method for fixing wired parts thereto. The inventive printed circuit board (10) comprises a recess (24, 24') in a peripheral area of each through bore (20). Bent loose ends (22) of the connecting pins or connecting wires (18) of the wired part (16) are placed in said recesses (24; 24''). The quality of the soldered joint is improved especially during overhead soldering in a reflow soldering furnace as the solder (32) flows into the recesses (24 or 24') and the through bores (20) during the overhead soldering process in the reflow furnace. The length of the connecting wires (18) effectively wetted by the solder (32) is greater than during conventional soldering, making the soldered joint more secure.

    • The invention enables lead-free soldering, in a reflow soldering furnace, of thermally critical, surface-mounted components together with thermally uncritical SMD components, on one side of a printed circuit board. Thermally critical and uncritical components (20, 22) are inserted into the soldering paste on the printed circuit board (10). According to the invention, said printed circuit board (10) is transported with other printed circuit boards (10), with the equipped first side facing upwards, through the reflow soldering furnace (30), and soldered in a soldering chamber (42). Thermal energy acting on the printed circuit board (10) in the lower region (46) thereof is adjusted in the soldering chamber (42) in such a way that the temperature on the lower side of the printed circuit board (10) is higher than that on the equipped upper side of the printed circuit board (10). The soldering paste on the upper side of the printed circuit board (10) is reliably melted by said indirect heating, and the temperature of the thermally critical components on the upper side of the printed circuit board (10) is maintained below the critical temperature.
