Description

Technical Field

[0001] The utility model relates to the technical field of packaging substrate tooling, in particular to an anti-warping hanging basket fixture. Background Art

[0002] Since the copper surface will oxidize if exposed to the air for too long, the package substrate needs to be treated with solder resist photosensitive ink before it is shipped to prevent oxidation failure of the copper surface and extend the product life. However, after the solder resist ink is screen printed on the entire copper surface, the ink is still wet and needs to be placed in a hanging basket fixture and baked briefly for pre-curing.

[0003] At present, in the existing hanging basket, during the baking process of the packaging substrate, the thickness of the packaging substrate is thinner than that of the traditional printed circuit board, and it is easy to deform during the production process. Most of the existing hanging baskets clamp it during baking to prevent deformation. However, clamping it too tightly may cause the risk of scratching the edge of the board, and clamping it too loosely may also cause risks such as warping of the board surface. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an anti-warping hanging basket fixture.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A warping-proof hanging basket jig comprises a hanging basket jig shell and a packaging substrate, wherein first bent plates are stamped on both sides of the hanging basket jig shell, supporting feet are integrally formed at the bottom of the hanging basket jig shell, and second bent plates are stamped on both sides of the supporting feet, a same bottom plate is placed on the top of the second bent plate, and an arc-shaped protrusion is provided on the top of the bottom plate, rivets are fixedly connected between the bottom plate and the second bent plate, a pressure block is slidably connected between the hanging basket jig shell and the first bent plate, an arc-shaped groove is provided at the bottom of the pressure block, a lifting handle is welded on the top of the pressure block, and the arc-shaped protrusion fits the arc-shaped groove.

[0007] Furthermore, an anti-slip sleeve is sleeved on the outer surface of the lifting handle.

[0008] Furthermore, the angle between the first bending plate and the inner wall of the hanging basket fixture shell is 90 degrees, and the angle between the second bending plate and the inner wall of the hanging basket fixture shell is 90 degrees.

[0009] Furthermore, the packaging substrate is located between the arc-shaped protrusion and the arc-shaped groove.

[0010] Furthermore, a ventilation hole is provided on one side of the hanging basket fixture shell.

[0011] Furthermore, lifting holes are provided on both sides of the top of the hanging basket fixture shell.

[0012] The beneficial effects of the utility model are:

[0013] 1. By providing an arc-shaped protrusion on the bottom plate and an arc-shaped groove at the bottom of the pressing block, the packaging substrate can be clamped by clamping the arc-shaped protrusion and the arc-shaped groove, so that the packaging substrate is baked in a bent state. The packaging substrate has a certain elasticity and can automatically rebound after baking, which can effectively avoid warping of the edge of the packaging substrate after baking, affecting the baking quality of the packaging substrate.

[0014] 2. By setting the pressing block to slide in the hanging basket fixture shell, the package substrate is clamped under the action of gravity, and the clamping force is appropriate and stable. Compared with the manual adjustment of traditional mechanical clamps, the stability is better, which improves the baking effect of the package substrate. BRIEF DESCRIPTION OF THE DRAWINGS
