Description

Technical Field

[0001] The invention relates to the field of DCB substrate manufacturing, in particular to a tooth angle positioning fixture. Background Art

[0002] When the second side of the DCB copper-clad ceramic substrate is sintered, a ten-point special fixture is required to prevent the copper foil sintered on the first side of the product from adhering to the ceramic plate underneath. This fixture is used in large quantities during the sintering production process and is a consumable item.

[0003] At present, the manufacturing method of the ten-point special fixture is as follows: first, put the ceramic plate d of the fixture into the bottom frame c with the arrow mark b, apply high-temperature organic glue to the bottom of the tooth angle a (support block), and then place the tooth angle a along the edge of the ceramic plate d according to the position indicated by the arrow mark b and fix it. Figure 1 .

[0004] The above-mentioned method of making a jig is relatively cumbersome and has low production efficiency. At the same time, since the tooth corners are placed directly on the ceramic plate manually, they are easily misplaced, which will eventually cause the product to be misplaced and affect the normal sintering of the product.
