FIG. 8 shows the flowchart 11 of the /V/co temperature control program, and from $1 to S8 are the entire system programs (because they are too detailed, their explanations will be omitted.
When the temperature of 1/υ is higher than the first light setting (200°C) and the magnetic card 65 is inserted into the reed shutter 37, the 1.11υ temperature setting IKU of this card is imported and the 7th meter (
S36), the solder quality measurement value of J:representation l[is taken in to the thermocouple 27 (S37), and this setting 11(1) is compared with the first measurement, and the error between the set value and the measured value is determined. Determine whether or not it falls within the proportional band (S38). If the above error is 110°C or more, compare whether the children are human or small (839), and if the measured l1Ci is b larger than the set value, start heating. For example, the timer takes 5 seconds (S40), S
37 and repeats 837 to S4o. When the above error becomes within lIo"c, the heater 22 is energized by the next proportional band rib routine and 1 to 11 heat J le (S
41) , :l: TA S3g TE measurement 1iQ is set (1
If the 0J-return is small, proceed to the heating rib routine: energize the repeater 22 and heat it (S42). Then, it is determined whether the solder temperature 1α is overheated to 280'C or higher ((S43), if the solder temperature 1α is over 1.0280'C or not, the For example, as shown in FIG. 7, the overheat alarm 11 is illuminated, and if this is the case, it is determined whether the operation Δ° switch f-42 is on or off (S44). If the operation on switch 42 is on (operating), the process returns to S31, and in steps 337 to S44, the main operation control of lν temperature is performed, and if the operation off switch 42 is not turned on (), the preparation off switch 41 is turned on. It is determined whether the off switch 41 is on or off (S45), and by turning on the off switch 41, the process returns to S36, where it is possible to change the set value, and by turning off the off switch 41, the process returns to S37, where the solder temperature is changed. Regarding control #, leakage operation continues.

FIG. 9 shows a flow chart of the heating subroutine in FIG. After the timer continues the process for, for example, 5 seconds (S), the SSR is turned off (S5o). The reason why the time for energizing the heater is determined from the beginning in this way is to prevent V-chittering when the temperature reaches a set value. If the above-mentioned energization is once stopped and the measured value has not reached the set value, the energization heating for 5 seconds will be repeated 8 immediately.

FIG. 10 shows the flow data 1.=1~ of the proportional band 1 Lujin in FIG. 8, and the ta? ? The on-time period of the timer 1701 is determined by the A'-on-off routine S51 (S52). This on/off n, ① determination is made according to the RA~1 data shown in the following table. For example, if the measured soldering temperature 1iQ is equal to the set value (for example, 250°C), the energization time to the control heater 22 is 10 seconds at A'' turn-off, and when the temperature of the it!i fixed field is 249°C, The on time is 11 seconds and the off time is 9 seconds.

(See next page) When the A-on-off time is determined in this way, for example, if the measured solder temperature is 249'C (3(, ff+
The SSR for the l+ heater 22 is kept on (S53) for 11 seconds by a timer (S54), and the SSR is kept off (355) for 9 seconds by a timer (S56).

Next, Figure 11 shows the preheat temperature control program 70-
For example, 7:3 is displayed by the calendar timer.
When the power supply to the pre-heater 3 starts at 0, the thermocouple 31
The current measured value of the atmospheric humidity (briheater temperature) of 1 night 3 is loaded into Buri (858), and this Buri heater 41m is displayed on the CRT (559), and the measured value is set to the set value for this Buri heater: It is determined whether the error is within the proportional band (S60).

If the error from the set value is ±10°C or more, then the above error does not fall within the proportional band. (S61).

If the measured value is human, it will be 858 without heating up.

~If SG2 is repeated and heated continuously, is the error X between the measured value and the set value proportional? i> (error is ±10
℃), then the pre-heater 3 is energized by the proportional band subroutine shown in Fig. 10 and the prefix (S63), and the pre-heater temperature (atmosphere temperature only) becomes the magnetic card setting 11). Until Buri Heater 3
Drive semi-biased. The steps 858 to S63 described above are performed until the operation on switch 42 is turned on, and then the main operation (soldering operation) starts (S64).
. During this actual operation, the thermocouple 31 detects the pre-heater ambient temperature (pre-heater temperature), and also detects the temperature on the side heated by the infrared radiation temperature J118 and the temperature on the bottom surface of the wiring board P (pre-heat temperature) without contact. The measured values of the sub-heater temperature and the sub-heater temperature of (a) are taken in (S65), and both of the measured temperature values are displayed on the CRT (866). In the main operation (soldering 1 operation), the above preheat temperature (print wiring I! 11 board temperature 1σ
) is compared with the set value, and it is determined whether the error falls within the proportional band (S6□). When the above error does not fall within the proportional band (±10°C or more),
It is determined whether the set value and measurement 1 are more or less than 1 (368).

When measurement 1iQ is a person, heating (to': i<, S6
Go to 5.

After repeating S68, if the measured value is small, energize the heater 3 in the heating rib routine shown in FIG. Of these, the error between the measured value and the constant value of Ω falls within the proportional band (the error is within ±10°C), so if you check the results in Figure 10 and @
The pre-heater 3 is energized ('S, 0) according to the ratio V/4 band subroutine shown in Figure 1, and the preheat temperature (
The pre-heater 3 is controlled so that the printed wiring pre-forming temperature) is set to the set value of the magnetic card. and turn on the operation off switch 43 (as long as you do not
Il is turned on continuously, and it is determined that the pre-heater 3 is operated one time by turning on (S71).

Next, FIG. 12 shows a flowchart 11 of the flux specific gravity subprogram, in which it is determined whether the quasi-cooperative on switch 40 is turned on or not (S14), and when it is turned on, whether the magnetic card 65 is inserted or not. /) 1 is determined (S), and if not inserted, S74. The judgment in S75 is repeated, and when the magnetic card is inserted, the settings 111J of the magnetic card are imported (
S76), and the current measured value of the flux specific gravity is taken in by the specific gravity product 112 (S, 7).

Next, it is determined whether or not the flux level has reached the upper limit level L1 by the upper limit detection needle 71 of the liquid level gauge 13 shown in FIG. 13 (878).
4JjJ: Both the solenoid valves 16 and 17 of the diluent tank 15 are closed (Syg), and the
(S 8o>, B￥Fi light and buzzer are activated. Also, if the flux surface is at the upper limit level and has not reached 1, the current i11+1 constant supply for the flux specific gravity is small or large compared to the set value. How it is judged (
S). The first measurement has a small gap G, 1'', and then it is determined whether the flux level has reached the intermediate level L2 by the intermediate limit detection 1172 of the liquid level screen 1-13 (38

When the intermediate level L2 has been reached, the GJ stock solution is not supplied,
In addition, if the level has not been reached, turn on the solid stay 1-relay (SSR) that opens the solenoid valve 16 for undiluted solution (583),
When the undiluted solution is supplied for a time determined by a timer (for example, 2 seconds) (584), it is determined whether or not the flux surface has reached the intermediate level L2 (S85), and the flow is continued in S7□ and S8 until reaching the intermediate level L2.
