In the manufacturing process of the double-sided mounting board, first, an electronic component such as a chip component or a discrete component is mounted on one surface of the wiring board and soldered by a reflow soldering process or the like. Next, the wiring board is supported with the mounting surface of the electronic component facing downward, and cream solder or paste solder is applied to the other substrate surface facing upward by a screen printing process. The components are mounted and sent to the heating furnace to complete the soldering operation.

In the cream solder application step and the electronic component mounting step, a backup board Bb that supports the substrate from the side where the electronic component is mounted first is used.
FIG. 10 shows a state in which the wiring board is supported by the backup board Bb. In FIG. 10, reference numeral 1 denotes a printed wiring board that can be mounted on both sides. A plurality of electronic components 2 are mounted on one mounting surface 1a of the printed wiring board 1 and soldered. A plurality of fitting holes 3a are formed in the backup board Bb in a matrix at regular intervals in the X and Y directions.
A fitting hole 3a corresponding to a supportable region between the electronic components 2 arranged on the mounting surface 1a of the printed wiring board 1 is selected, and the support pin 4 is fitted into the selected fitting hole 3a.
The printed wiring board 1 is installed with the mounting surface 1 a facing downward, and the printed wiring board 1 is supported by the support pins 4 from between the electronic components 2. Cream solder is applied by screen printing to the other mounting surface 1b of the printed wiring board 1 in this supported state, and then, electronic components are mounted, and further carried into a heating furnace, where various types of electronic components are transferred to the mounting surface 1b on the upper surface side. Component mounting is completed.

After the automatic mounting of the electronic component 2 on the printed wiring board 1 is completed, the printed wiring board 1 is inspected by the inspection board 5 as shown in FIG.

In the manufacturing process of the backup board Bb shown in FIG. 10, it is conventionally determined which of the fitting holes 3a on the backup board Bb the support pins 4 should be arranged by the following method. It was done in For example, a place that does not hit the electronic component 2 is selected and assumed in advance among a plurality of fitting holes 3a provided on the backup board Bb, and the support pins 4 are implanted in the selected fitting holes 3a. . Next, the component mounting surface 1 of the printed wiring board 1 is actually
The a side is placed on the plurality of support pins 4, and the support pins 4 that come into contact with the electronic component 2 are removed, or a new location that does not contact the electronic component 2 is searched for and supported in the fitting hole 3a at that location. Work such as planting the pins 4 is performed.

[0007] Such work is performed manually, but the work of selecting a place that does not hit the electronic component 2 and arranging the support pins 4 is extremely complicated. In addition, since the printed wiring board 1 must be supported in a well-balanced manner by the support pins 4 in a state where the support pins 4 have been implanted, skilled work is required to determine the installation position of the support pins 4. Become.

Next, in order to determine the mounting position of the inspection stylus 7 on the inspection board 5 shown in FIG. 11, the mounting position of the inspection stylus 7 is conventionally determined from the pattern drawing of the printed wiring board 1. The size was measured and measured on the inspection board 5, and the fitting hole 5a was drilled with a drill. However, in this method, the fitting hole 5 determined by the dimensions from the drawing is used.
An error is likely to occur between the perforation position a and the actual inspection position of the printed wiring board 1, and the problem that the manufactured inspection board 5 cannot be used is likely to occur. Further, as another method for setting the position of the fitting hole 5a, a drilling position of the fitting hole 5a is obtained by a digitizer or the like, processing data is created based on the detection data, and N is determined based on the processing data.
Some of them pass through a step of drilling the fitting hole 5a with a C processing machine or the like. However, this method complicates the process,
The production cost of the inspection board increases.

In the recording apparatus B shown in FIG. 9, the table T is supported on the base 15 via the intermediate table T2 so as to be movable in the XY coordinate plane, as in the first embodiment. A console 27 is provided at the back of the base 15, and a part of the console 27 is provided with a support console 27 a protruding in the direction of the base 15, and has a drive motor M (not shown) at a distal end thereof. A processing machine is mounted to be able to move up and down freely. At the end of the drive motor M, a drill 28 is provided as a recording means for forming a mounting portion of the support projection (support pin) 4 so as to protrude downward.

From the other part of the console 27, a support arm 22 is provided in parallel with the support console 27a, and an illuminating device La is supported at the tip of the support arm 22 as detection means. The table T has handles 24b, 24
b can be moved on the XY plane on the base 15, but on this table T, a board installation section 13 on which the printed wiring board 11 is installed, and a backup board as a recording medium A recording body installation section 29 on which Bb or the inspection board 5 is installed is provided, and the backup board Bb or the inspection board 5 is installed on the recording body installation section 29 and fixed.

In this apparatus, the illuminating device La always irradiates the wiring board 11 with spot light, or uses a coordinate position detecting means as shown in FIGS. From the device La to the wiring board 1
1 is irradiated with a spot light. Move table T,
The table T is stopped when the spot light irradiates the supportable position 11b of the mounting surface 11a of the wiring board 11 or the inspection position where the inspection stylus 7 is brought into contact. At this time, the table T is lightly locked by the coordinate position detecting means shown in FIG. 5 or the like, or the table T is locked by another locking mechanism. Then, the backup board Bb or the inspection board 5 is directly processed by the drill 28 to form the fitting hole 3a or 5a.

Thus, after the processing is completed, the backup board can be manufactured by fitting the support projections (support pins) 4 into the fitting holes 3a of the backup board Bb. Alternatively, as shown in FIG. 11, the test board is completed by fitting the holder 7a of the test stylus 7 into the fitting hole 5a. As a recording means, an adhesive layer for adhering the support projections (support pins) 4 may be attached to the surface of the backup board Bb instead of the drill. Alternatively, marking may be performed on the backup board Bb or the inspection board 5 as a mounting portion, and the marked portion may be processed later to form the fitting hole 3a or 5a.

In the first and second embodiments, the operator manually checks the spot of the illuminating device La and thereafter operates the drilling machine 19 or the drill 28. The device La can be replaced with, for example, a three-dimensional measuring device that can acquire three-dimensional data that three-dimensionally captures the uneven shape of the mounting surface of the substrate. The three-dimensional measuring device determines the supportable position 11b or the inspection position of the wiring board 11 based on the three-dimensional data, processes this as a predetermined coordinate system as two-dimensional plane data, and attaches the support protrusion 4. The position and the position where the inspection stylus 7 is attached can be determined. Then, based on the plane data, the recording sheet 25 can be created and the fitting hole 3a of the backup board Bb can be automatically formed. The three-dimensional data is processed by software of a computer, and the supportable position 11b of the wiring board 11 or the inspection position is determined.

Further, in the above example, the illumination device La, the drilling machine 19 or the drill 28 side is fixed, and the table T side is moved. However, the present invention is not limited to this. A structure in which the T side is fixed and the integrally formed illuminating device La, the drilling machine 19, or the drill 28 side may move.
