    • 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.

    • In wave soldering systems known in prior art, components or terminal pins are soldered onto a bottom surface of circuit boards. For this purpose, a solder wave composed of liquid solder runs across said bottom surface. In order to simultaneously solder components (26) on the top surface and components (42) or pins on the bottom surface (40) of circuit boards (10), according to the invention, the speed of travel of the circuit boards (10) through the wave soldering system (50) is adjusted such that heat is transferred from the solder wave (60) through the circuit boards (10) to the top surface of the printed boards (10), thus allowing components (26) that are inserted into solder paste (24) to be soldered onto the top surface. The solder wave (60) brushes across the bottom surface (40) of the circuit boards (10) and solders in a previously known fashion there. The circuit boards (10) are conveyed over the solder wave (60) in a substantially horizontal direction and without being positioned at an angle of attack, as commonly done in prior art.
