2. Description of the Related Art Resin mold type electronic parts are
It is housed in a baking device to accelerate the hardening of the resin.

The electronic component using a lead frame is put into a baking apparatus in a state where a large number of lead frames are accommodated in a tray. Since the lead frame has good thermal conductivity, electronic components inside the tray are used. However, heat can be transferred to the resin through the lead frame, and the resin can be cured efficiently.

On the other hand, a TAB tape having an inner lead formed by extending a part of a conductive pattern laminated on a long insulating film having a through hole into the through hole is used. TAB type electronic parts with a structure coated with resin for the purpose of connecting to and protecting the surface of the electronic parts body are generally stored and transported by winding TAB tape around the reel. Since it is difficult for heat to be transferred to the inside when wound, it is possible to cut the TAB tape in a strip shape and convey it in the baking device, or move the TAB tape fed from the reel while guiding it along the conveyance path. I have to. Since the TAB tape does not have good thermal conductivity, a heating means is arranged along the conveying path so that the radiant heat directly hits the resin.

FIG. 3 shows an example of an in-line baking apparatus for continuously curing the resin of the TAB type electronic component. In the figure, reference numeral 1 is a heat insulating chamber made of a heat insulating material, and both side walls 1
Small windows 1c and 1d are provided in a and 1b. Although not shown, a door that can be opened and closed is provided on the front surface. Two
a, 2b, 2c are guide rails arranged at different height positions inside the heat insulation chamber 1, and 3a, 3b are guide rails 2.
The sprocket wheels 4 arranged at the end portions of a, 2b, and 2c are TAB tapes that connect the electronic component body (not shown) and cover the surface with resin (not shown). It is inserted into the chamber 1, guided by a guide rail, changed in direction by a sprocket wheel, and sequentially conveyed, and is drawn out of the heat insulating chamber 1 through another window 1d. Reference numerals 5a, 5b, 5c, 5d, and 5e denote heaters arranged along the moving path of the TAB tape 4.

The size of the electronic component body of the TAB tape 4 differs depending on the model of the electronic component, and the number of electrodes also varies depending on the degree of integration. For example, the width is 35 mm, 48 mm, 70 mm.
Since the width is used, the width of the guide rail 2 and the sprocket wheel 3 of this in-line bake device can be changed.

[0007]

By the way, in order to change the width of the TAB tape 4, the previous TAB tape is changed to the heat insulation chamber 1.
After being completely removed from the heat insulating chamber 1, the door of the heat insulating chamber 1 is opened, the width of the guide rail 2 and the sprocket wheel 3 is changed, the guide tape for introducing the next TAB tape into the heat insulating chamber 1 is set, and then the door is closed. The next TAB tape can be baked.

Therefore, from the previous TAB tape to the next TA
It takes time to switch to the B tape, and the heat in the heat insulating chamber 1 escapes to the outside due to the opening of the door. It takes time to reach the predetermined temperature, and the conveyance speed of the next TAB tape is slowed until the temperature reaches the predetermined temperature. Since it has to be done, there is a problem that it takes more time.

Further, there is a problem that the utility cost is wasted.
