Abstract

A substrate includes a substrate body, a flux coating portion which is coated with flux promoting solder fluidity on a surface of the substrate body, a conduction portion which is disposed on the surface of the substrate body to be separated from the flux coating portion and is conductive, and a silk portion which is disposed between the flux coating portion and the conduction portion on the surface of the substrate body and is provided by silk printing.

First claim

What is claimed is:

1. A substrate comprising:
a substrate body;
a flux coating portion which is coated with flux promoting solder fluidity on a surface of the substrate body;
a conduction portion which is disposed on the surface of the substrate body to be separated from the flux coating portion and is conductive;
a resist portion which is disposed between the flux coating portion and the conduction portion on the surface of the substrate body and is formed to be higher than the flux coating portion and the conduction portion from the surface of the substrate body; and
a silk portion which is disposed between the resist portion and the conduction portion and is provided by silk printing.

2. The substrate according to claim 1 ,
wherein the conduction portion is disposed to surround the vicinity of a fixing hole which is formed in the substrate body such that a screw fixing a housing and the substrate body is inserted into the fixing hole.

3. The substrate according to claim 1 , further comprising:
a base portion which is formed to be higher than the flux coating portion and the conduction portion from the substrate body,
wherein the silk portion is disposed on the base portion.

4. An electric compressor, comprising:
the substrate according to claim 1 ; and
a motor which is operated according to an AC current supplied from the substrate.

5. An air conditioner, comprising:
the electric compressor according to claim 4 ,
wherein the air conditioner is mounted on a vehicle.

6. The substrate according to claim 1 ,
Wherein the silk portion is disposed with a clearance between the silk portion and the resist portion.
