産業上の利用分野
本発明はプリント基板に部品を半田付する場合に用いる
ことができる炉に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a furnace that can be used for soldering components to printed circuit boards.
従来例の構成とその問題点
セラミック基板上に導電パターンを形成し、この導電パ

をすることが行われている。Conventional Structure and Problems A conductive pattern is formed on a ceramic substrate, a part of the conductive pattern is coated with cream solder, and parts are placed on top of this. A device constructed in this way is placed in a furnace and soldered.

ック基板１をいちいち金属性パレット３にはめ合せなけ
れ７／ｆならす量産に適さないものである。However, as shown in Fig. 1, if the parts such as the heat sink attached to the back side of the ceramic substrate 1 protrude from the ceramic substrate 1, if the parts 2 are placed in the furnace as they are, the protruding parts of the parts 2 will be exposed to the heat source. The heat will be directly irradiated, and the protruding parts will be burnt by the heat. Therefore, in order to eliminate this drawback, as shown in FIG. 2, parts other than the ceramic substrate 1 are covered with a metal pallet 3 to prevent heat from directly hitting the protruding parts of the parts 2. ing. However, this method is not suitable for mass production in which the ceramic substrate 1 must be fitted onto the metal pallet 3 one by one to achieve 7/f.
発明の目的
本発明は各セラミック基板にパレットをはめ合せる必要
がない炉を提供しようとするものである。OBJECTS OF THE INVENTION The present invention seeks to provide a furnace that does not require a pallet to be fitted to each ceramic substrate.

。Structure of the Invention The present invention provides a heat shielding plate between an object to be heated and a heat source, which partially blocks heat coming directly from the heat source, and heat-shields objects that should not be heated. It is something.
実施例の説明
以下本発明の一実施例について図面を参照して説明する

り、移動しながら加熱されるので、部品のはみ出し部分
に熱が当らないように、熱遮蔽板７を連続して設ける。A lamp 6 as a heat source is placed above the glass plate 5. A heat shield plate for heat shielding is placed on this glass plate 5. The heat shield plate 7 is made of a ceramic plate, a metal plate, etc., and is provided by combining a plurality of small plates. The heat shielding plates 7 are arranged in such a way that, for example, when a component protrudes from the right side of the ceramic substrate that is the object to be heated, the heat from the lamp 6 does not directly hit the protruding part. Since the object to be heated moves on the conveyor 8 and enters the furnace, and is heated while moving, a heat shield plate 7 is continuously provided so that the protruding parts of the parts are not exposed to heat.
このようにすることによって特別なバレントを必要とし
ないものである。By doing this, no special valence is required.
発明の効果
以上のように本発明によれば特別なパレットを被加熱体
にいちいちはめ合せる必要がないものであり、量産に適
するものである。Effects of the Invention As described above, according to the present invention, there is no need to fit a special pallet to the object to be heated each time, and it is suitable for mass production.
