Abstract

PURPOSE:To harden a molten solder in a short time, to shorten the time while a lead terminal is held at high temp. and to prevent the adverse effect due to heating by working a cooling means with a control means by the scheduled time after a solder layer being melted by a heating means. CONSTITUTION:When the temp. of a heating chip 5 reaches a set temp., a temp. detection S6 from a thermocouple 6 is given to a comparator 17 to detect the reach to the set temp.

At the time when the heating time elapsed, a heating completion signal Sa is outputted from a cycle counter 15 and the phase control by the thyristors 20, 21 is stopped by an ignition pulse generating circuit 19. A cooling signal S22 is simultaneously outputted by a sequence control circuit 22, a solenoid valve 9 is released, a cooling air is blown via a blast pipe 8 from a cooling air feeding source and the heating chip 5, lead terminal, molten solder and conductor pattern are cooled.

(Problems to be Solved by the Invention) However, in the above conventional configuration, when the heating chip is cut off after heating and melting the solder layer, the heat capacity is relatively large.
The solder is cured by letting it cool naturally while pressing the lead terminal with a heating tip.
It takes a long time for the solder to harden. For this reason, soldering has the disadvantage that the entire operation takes a long time, and also has the disadvantage that it is difficult to perform automatic soldering. We also have heating chips and lead terminals.

Next, the operation of the above configuration will be described with reference also to FIGS. 3 and 4. As shown in FIG. 3, first, the heating chip 5
1liA degrees of ambient; I is from degrees Tl to set temperature T3 (
For example, when the welding transformer 2
As shown in FIG.
Phase control of the cyrisk 20.21 is performed so that it increases between -t2. Subsequently, at time t2, the heating tip 5
When the temperature reaches the set temperature T3, the temperature detection signal S6 from the thermocouple 6 is applied to the comparator circuit 17 via the amplifier circuit 18, and the comparator circuit 17 detects that the set temperature T3 has been reached. As a result, the phase conversion circuit 14 controls the thyristor 20.21 so that the value of the welding current C23 and thus the heating output of the heating tip 5 are reduced to about 1/2 between times t2 and t3 as shown in FIG. Phase control is performed. Then, at time t3 when the set heating time has elapsed, when the cycle counter 15 outputs the heating end signal Sa, the ignition pulse generating circuit 19 that receives the heating end signal Sa starts the phase control by the thyristor 20.21. will be stopped. At the same time, the sequence control circuit 22 receives the heating end signal Sa and outputs the output terminal 0.
2, the output of the cooling signal S22 is started, and the solenoid valve 9 is opened accordingly. Then, the cooling air from the cooling air supply source 10 is blown through the cooling air supply hole 8a of the ventilation vibrator 8, and the heating chip 5. Lead terminal 3. Molten solder and conductor pattern 1
is rapidly cooled. Thereafter, when the cycle counter 15 outputs the cooling end signal sb at time t4, the sequence control circuit 22 stops outputting the cooling signal S2□, and in response, the solenoid valve 9 is closed and the above-mentioned Cooling is stopped. At this time, the temperature of the lead terminal 4 portion falls to the solder freezing point temperature T2 (approximately 180° C.), thereby hardening the molten solder.

According to this embodiment having such a configuration, the cooling means 7 is provided, and after heating the heating chip 5, the cooling means 7 is operated for a predetermined period of time to cool the heating chip 5. Lead terminal 4. Since the molten solder and the conductor pattern 1 are forcibly cooled, the time required for the molten solder to harden can be shortened compared to the conventional method in which the molten solder is naturally cooled. Therefore, since the time required for the entire soldering operation is shortened, it becomes possible to perform automatic soldering. In addition, the heating chip 5. Since the time for which the lead terminals 4 and the conductor pattern 1 are kept in a high temperature state is shortened, there is a risk that the electronic component 3 may be destroyed by the heat or the conductor pattern 1 may be peeled off from the printed wiring board 2 due to the heat. Therefore, the quality of soldering can be improved.
