Definitions
- the present invention relates to an anisotropic conductive connector, a conversion adapter and an inspection device for an inspection apparatus including the anisotropic conductive connector, and a method for manufacturing the anisotropic conductive connector.
- the present invention relates to an anisotropic conductive connector provided between the electronic component and the inspection circuit board to electrically connect the electronic component to be inspected and the inspection circuit board.
- the present invention relates to a conversion adapter for an inspection apparatus and an inspection apparatus that include an anisotropic conductive connector, and a method for manufacturing the anisotropic conductive connector.
- This anisotropically conductive sheet is generally configured such that a conductive path is formed only in the thickness direction when pressed, and damages the electrodes of electronic components to be inspected during electrical inspection. This is effective in that a reliable electrical connection with the inspection apparatus can be achieved.
- this anisotropic conductive sheet is used for electrical inspection of electronic parts such as BGA having a fine electrode pitch, the fine and high-density electrodes of the electronic parts and the anisotropic conductive material are used.
- the alignment with the conductive path of the sheet is important, and as the pitch between the electrodes becomes finer and higher in density, the importance increases and a technical response has been demanded.
- an opening is provided between the electronic component 1 to be inspected and the anisotropic conductive sheet 2 at a position corresponding to the protruding electrode 3 of the electronic component 1.
- Insulating sheet 5 with 4 is placed, and electrode 3 of electronic component 1 is fitted into opening 4 to Techniques for positioning the conductive path 2 on the conductive path 6 have been proposed. (For example, see Patent Literatures 1 to 5).
- Patent Document 1 Japanese Patent Laid-Open No. 11-1603963
- Patent Document 2 Japanese Patent Laid-Open No. 10-84972
- Patent Document 3 Japanese Patent Laid-Open No. 2001-93599
- Patent Document 4 JP-A-8-271578
- Patent Document 5 Japanese Patent Laid-Open No. 10-10191
- the positioning member force of the insulating sheet 5 or the like is provided separately from the anisotropic conductive sheet 2, so that the anisotropic conductive sheet is provided during electrical inspection. It was necessary to position the positioning member with respect to 2. For this reason, it is difficult to reliably align the electrode 3 of the electronic component 1 with the conductive path 6 of the anisotropic conductive sheet 2.There is a possibility that sufficient electrical connection between the two cannot be ensured, and the inspection work is troublesome. There was also a problem that the force was applied.
- the above-described conventional positioning member is formed of an insulating material and has insufficient heat resistance, and thus may be deformed by heat generated during electrical inspection.
- the positioning member is made of a heat-resistant metal material or the like, it is difficult to process the opening 4 according to the fine and high-density electrode 3 of the electronic component 1, and there is no positioning member.
