Abstract

A climate chamber for measuring electronic circuits, having a housing that includes an interior space and an opening. The interior space is at least thermally insulated from the surroundings by the housing. Two movable jaws each have an end face. An interior space in a region of an opening is distanced from the surroundings according to the thickness of the jaws, and the jaws each comprise a thermal insulation layer, and each jaw has a front side facing the surroundings and a back side facing the interior space. The two jaws are spaced apart by a clear width being formed between the two end faces, so that the circuits disposed on a carrier can be introduced into the climate chamber and in a second state, the opening for the protection of the interior space is sealed against ambient conditions.

First claim

What is claimed is:

1. A climate chamber for measuring electronic components, the climate chamber comprising:
a housing that comprises an interior space and an opening, the interior space being at least thermally isolated from external surroundings by the housing;
two movable jaws that each have a width and a height and a thickness and an end face, the thickness and width of the respective jaw determining a surface of the end face, the two end faces of the two jaws being opposite to each other and the surfaces of the end faces forming mutually parallel planes,
wherein the interior space adjacent to the opening is distanced from the external surroundings according to the thickness of the jaws,
wherein each of the two jaws have a thermal insulation layer, and each jaw has a front side that faces the external surroundings and a back side that faces the interior space, a size of the front side and back side being determined by the width and the height of each jaw,
wherein, in a first state, the two jaws are spaced apart by a clear width being formed between the two end faces so that the electronic components arranged on a carrier, the carrier being connected to the electronic components for moving the electronic components into the interior space,
wherein, in a second state, the opening, for the protection of the interior space, is sealed against ambient conditions, and
wherein the electronic components are connected by an electrical connection and the electrical connection is guided between the two jaws, and the end face of one of the two jaws and the end face of the other jaw are each non-positively connected with the electrical connection.

2. The climate chamber according to claim 1 , wherein the two jaws at the respective end face are thermally coupled with a top side and with an underside of the carrier so that at a border to the interior space, the carrier assumes an internal temperature, and at the border to the surroundings the carrier assumes the ambient temperature.

3. The climate chamber according to claim 1 , wherein the opening is sealed by the two jaws and the carrier, and wherein the carrier is clamped between the two end faces.

4. The climate chamber according to claim 1 , wherein the carrier is substantially equal in width with one of the jaws.

5. The climate chamber according to claim 1 , wherein the two jaws have identical thicknesses and identical widths.

6. The climate chamber according to claim 1 , wherein on a top side of the carrier, a plurality of conductor paths and contact regions for one or more circuits are provided, and wherein the conductor paths are in electrical operative connection with the contact regions and the contact regions are arranged to electrically contact one or more circuits.

7. The climate chamber according to claim 1 , wherein the surface of the front side and the surface of the back side form mutually parallel planes.

8. The climate chamber according to claim 1 , wherein the thermal insulating layer has an air layer and each of the two jaws comprises two partial jaws, wherein in each case the front side is formed of the first partial jaw and respectively the back side of the second partial jaw.

9. The climate chamber according to claim 1 , wherein the carrier is plate-shaped and the end face of one of the two jaws is in each case non-positively connected with a top side of the carrier, and wherein the end face of the other jaw with an underside of the carrier.

10. The climate chamber according to claim 1 , wherein the carrier and the electronic components are suspended in the interior space.

11. A climate chamber for measuring electronic components, the climate chamber comprising:
a housing that comprises an interior space and an opening, the interior space being at least thermally isolated from external surroundings by the housing;
two movable jaws that each have a width and a height and a thickness and an end face, the thickness and width of the respective jaw determining a surface of the end face, the two end faces of the two laws being opposite to each other and the surfaces of the end faces forming mutually parallel planes,
wherein the interior space adjacent to the opening is distanced from the external surroundings according to the thickness of the jaws,
wherein each of the two jaws have a thermal insulation layer, and each jaw has a front side that faces the external surroundings and a back side that faces the interior space, a size of the front side and back side being determined by the width and the height of each jaw,
wherein, in a first state, the two jaws are spaced apart by a clear width being formed between the two end faces so that the electronic components arranged on a carrier are adapted to be introduced into the interior space,
wherein, in a second state, the opening, for the protection of the interior space, is sealed against ambient conditions,
wherein the electronic components are connected by an electrical connection and the electrical connection is guided between the two jaws, and the end face of one of the two jaws and the end face of the other jaw are each non-positively connected with the electrical connection, and
wherein the thermal insulation layer is formed between a first actively temperature-controlled partial jaw and a second temperature-controlled partial jaw, wherein the second partial jaw borders on the interior space and exhibits the temperature of the interior space and the first partial jaw borders on the surroundings so that a temperature difference between the interior space and the surroundings between the two partial jaws drops.

12. The climate chamber according to claim 11 , wherein active temperature control by the two partial jaws is effected by a fluid.

13. The climate chamber according to claim 11 , wherein the first partial jaw is formed as an actively temperature-controlled partial jaw and exhibits the temperature of the surroundings so that a temperature difference between the interior space and the surroundings between the two actively temperature-controlled partial jaws drops.

14. The climate chamber according to claim 11 , wherein the two partial jaws cover the entire front side and the entire back side of each jaw.
