Electrical equipment 1 includes a chassis 2 that has a bottom portion 3 and side portions 4 and 5, a printed circuit board 10 that is stored in the chassis 2 such that one principal surface 10a faces an inner surface 3a of the portion 3, a sealing resin 20 that is filled in internal space S formed by the chassis 2 and the circuit board 10, embeds the circuit board 10, and a flow suppression portion 8 that decreases a drift velocity of the resin 20 pressed into the space S through the resin injection hole 11, and that is provided in at least part of region A from a position immediately below the hole 11 in the inner surface 3a to an inner surface 4a of a side portion 4 closest to the hole 11 out of the side portions 4 and 5.
Electrical equipment comprising:
A production method of electrical equipment comprising:
A design method of electrical equipment comprising a chassis that has a bottom portion and a plurality of side portions and is opened upward, a printed circuit board in which a resin injection hole that penetrates in a thickness direction is provided, and that is stored in the chassis such that one principal surface faces an inner surface of the bottom portion, and a sealing resin that is filled in the chassis and embeds the printed circuit board, where a flow suppression portion that decreases a drift velocity of the sealing resin pressed into an internal space, which is formed by the chassis and the printed circuit board when the printed circuit board is stored in the chassis, through the resin injection hole before the sealing resin is hardened, is provided in at least part of a region from the inner surface of the bottom portion immediately below the resin injection hole to an inner surface of a side portion closest to the resin injection hole among the plurality of side portions.
