のとなっておシ、互換性は全くない。Conventional technology In household electrical appliances such as microwave ovens, the number of electronic products and those equipped with microcomputers (hereinafter referred to as "microcomputers") has been rapidly increasing, and printed circuit boards equipped with microcomputers are becoming increasingly important. It's here. Also, as the number of sets increases, the number of types has increased significantly. Figures 6 and 7 are examples of printed circuit boards for conventional microwave ovens. Although the size of the set is the same, the stain source capacity increases or decreases due to the addition of additional functions such as a humidity sensor. There is a difference in whether a low voltage transformer can be mounted directly on a P board or whether it must be a lead type. To install the humidity sensor type body, there is a need to cut out part A in order to attach the polyureum on the top and 3 pages on the bottom. Fig. 6 shows the case without the humidity sensor, and Fig. 7 shows the case with the humidity sensor. Therefore, the printed circuit boards of both are completely different and are not compatible at all.

いる。Problems that the invention aims to solveAlthough they are the same set, low voltage transformers are divided into direct-mounted type and lead-centered type depending on whether or not there is a sensor, and printed circuit boards are completely different9.There are many types. There are major issues in terms of quality, cost, and schedule.

問題となってきた。In addition, recently, when microwave ovens were returned to the market, cracks were occurring in the printed circuit boards.The cracks were also in irregular locations and difficult to repair, so we are currently looking into ways to prevent the cracks. However, there is nothing drastic, and this has also become a serious problem.

ン目を構成した制御基板である。Means for Solving the Problems A control board of the present invention includes a control section, a low voltage transformer for supplying power to the control section, and a printed circuit board on which the control section and the low voltage transformer are mounted, This is a control board in which perforations in the printed circuit board are configured to divide the primary side and secondary side of the control board.

よシ、プリント基板の共用化が図れる。Function: This control board has perforations on the primary and secondary sides of the low-voltage transformer, and one divided printed circuit board carries only the pattern on the primary side of the low-voltage transformer. In addition, as a response to the case where the low voltage transformer is lead-centered, remove one of the divided printed circuit boards and install a connector where it connects to the secondary side pattern on the other printed circuit board. It is possible to connect the secondary side lead sensor connector of the lead center type low voltage transformer.
Fortunately, it is possible to share printed circuit boards.

部分がミシン目割れとなるであろう。FIG. 2 shows how the low voltage transformer pattern runs on the printed circuit board of the present invention, and the pattern from the secondary side of the low voltage transformer is connected to the connector. FIG. 3 shows a state in which the printed circuit board is assembled into the top mark base U. This part is directly incorporated into the main body, next to the door. When the set is dropped, the weakest part of the control board of the present invention (weak point) is the perforation between the primary and secondary sides of the low voltage transformer. Therefore, in case of a strong fall, that part will be the first to perforate.
しかし、それ以後の落下はそのミシン目の部分に力が集
