Description

Technical Field

[0001] This utility model relates to the field of development and etching technology, and in particular to a common tooling for developing and etching DPC substrates. Background Technology

[0002] The DPC substrate development and etching process first uses vacuum deposition to sputter a copper-metal composite layer onto the ceramic substrate. Then, photoresist is applied using photolithography, followed by exposure, development, etching, and stripping to fabricate the circuitry. Finally, electroplating / chemical plating is used to increase the thickness of the circuitry. After the photoresist is removed, the metallized circuitry is complete. DPC ceramic substrates are small, have precise structures, require high reliability, and involve complex and meticulous manufacturing processes. This is a technology-intensive industry with high technological barriers.

[0003] Currently, most of the mainstream developing and etching fixtures are flat fixtures that cannot be rotated or adjusted in angle. When developing and etching patterns by spraying from above and below, it is easy to cause problems such as overdevelopment and etching due to residual etching solution or incomplete development and etching due to loss of etching solution. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to realize a common tooling for developing and etching DPC substrates in multiple directions by adjusting the angle and rotating.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A common fixture for developing and etching DPC substrates includes a guide rail, a limiting slider, a rotary motor, and a connector. The rotary motor is fixed on the limiting slider, which is mounted on the guide rail. The connector includes a connecting part and a bolt clip. One end of the bolt clip is connected to the rotary motor through the connecting part, and the other end clamps a sample. The rotary motor drives the sample to rotate through the connector to adjust the sample angle.

[0007] Preferably, the guide rail is a perforated guide rail, and the limiting slider is slidably connected to the perforated guide rail.

[0009] Preferably, the connecting part includes a connecting end and a telescopic rod, one end of the telescopic rod is connected to the rotary motor through the connecting end, and the other end is connected to the sample through the bolt buckle.

[0010] Preferably, the bolt clip further includes a connector and two connecting rods respectively connected to the connector, and the other end of the connector is connected to the telescopic rod.

[0011] Preferably, the axes of the two connecting rods form an angle.

[0012] Preferably, the axes of the two connecting rods are distributed at 90 degrees.

[0013] Preferably, the bolt clip includes an adjusting bolt and a clamp. The clamp includes a fixed clamping plate and a movable clamping plate. The movable clamping plate is provided with bolt holes. The adjusting bolt passes through the bolt holes to fix the fixed clamping plate and the movable clamping plate.

[0032] Figures 1-6 This utility model discloses a common tooling for developing and etching DPC substrates, including a guide rail, a limiting slider 200, a rotary motor 300, and a connector 400. The rotary motor 300 is fixed on the limiting slider 200, which is mounted on the guide rail. The connector 400 includes a connecting part and a bolt clip 403. One end of the bolt clip 403 is connected to the rotary motor 300 through the connecting part, and the other end clamps the sample 500. The rotary motor 300 drives the sample 500 to rotate through the connector 400 to adjust the angle of the sample 500.

[0033] In a preferred embodiment, the guide rail is a perforated guide rail 100, and the limiting slider 200 is slidably connected to the perforated guide rail 100.

[0034] Specifically, the perforated guide rail 100 is provided with multiple positioning holes, and the limiting rod 204 passes through the positioning holes and engages with the perforated guide rail 100, thereby fixing the tooling on the perforated guide rail 100 and making the tooling spacing adjustable at fixed points.

[0035] The limiting slider 200 also includes a switch 202, a connecting rod 203, a slider housing 201, and a limiting rod 204 built into the slider housing 201. The slider housing 201 is located inside the perforated guide rail 100, and the switch 202 is located on the slider housing 201. The connecting rod 203 is fixedly connected to the slider housing 201, and the rotary motor 300 is fixed to the connecting rod 203. The switch 202 controls the limiting rod 204 to extend out of the slider housing 201 and engage with the perforated guide rail 100.

[0036] Specifically, the cross-sectional height of the perforated guide rail 100 is adapted to the cross-sectional height of the slider housing 201. The slider housing 201 is made of polymer, which effectively prevents corrosion by the solution.

[0037] Specifically, the housing of the rotary motor 300 is made of polymer, which is waterproof, corrosion-resistant, and sealed, effectively preventing corrosion by solutions. The rotary motor 300 allows the sample 500 to rotate, thereby adjusting the angle of the sample 500. Each rotary motor 300 can be operated independently.

[0038] The connecting part includes a connecting end 401 and a telescopic rod 402. One end of the telescopic rod 402 is connected to the rotary motor 300 through the connecting end 401, and the other end is connected to the sample 500 through a bolt clip 403. The connecting part 400 clamps the sample 500, and the number of samples 500 can be increased or decreased according to the actual needs of the production line by increasing or decreasing the number of connecting parts 400.

[0039] Specifically, there are multiple connectors 400.

[0040] Specifically, the telescopic rod 402 is adjustable in length to accommodate samples 500 of different sizes.

[0041] The bolt clip 403 also includes a connector 4031 and two connecting rods 4032 connected to the connector 4031 respectively. The connector 4031 is connected to the telescopic rod 402, and the axes of the two connecting rods 4032 form an angle.

[0042] In this embodiment, the axes of the two connecting rods 4032 are distributed at 90 degrees. In other embodiments, the included angle formed by the axes of the two connecting rods 4032 is adapted to the included angle of the cross section of the sample 500.

[0043] The bolt clip 403 includes an adjusting bolt 4034 and a clamp 4033. The adjusting bolt 4034 is located on the clamp 4033. The DPC substrate developing and etching common fixture adjusts the opening and closing size of the clamp 4033 via the adjusting bolt 4034 to accommodate samples 500 of different thicknesses. The operator can also install samples 500 of different sizes and thicknesses by adjusting the length of the adjusting bolt 4034 and the telescopic rod 402.

[0044] Specifically, the connecting rod 4032 is connected to the clamp 4033.

[0045] Specifically, the number of clamps 4033 is equal to the number of connecting rods 4032.

[0046] like Figure 6 As shown, the clamp 4033 includes a fixed clamping plate 40331 and a movable clamping plate 40332. The movable clamping plate 40332 is provided with bolt holes, and the adjusting bolt 4034 passes through the bolt holes and is vertically fixed on the movable clamping plate 40332.

[0047] The bolt clip 403 also includes a flexible pad 4036 and a flexible baffle 4035. The flexible pad 4036 is located on the inner wall of the clamp 4033, and the flexible baffle 4035 is fixed on the fixed clamping plate 40331 and located inside the adjusting bolt 4034. The flexible pad 4036 allows the bolt clip 403 to clamp more tightly while avoiding damage to the sample 500. The flexible baffle 4035 acts as a limiter to prevent the sample 500 from hitting the adjusting bolt 4034.

[0048] Specifically, the flexible baffle 4035 and the flexible pad 4036 are integrated and made of a corrosion-resistant flexible polymer. Since there are no patterns at the four corners of sample 500, the bolt clips 403 will not affect the development and etching of the surface pattern of sample 500.

[0049] Specifically, the fixing clamp 40331 is L-shaped.

[0050] In this application, when using the DPC substrate developing and etching common fixture, the limiting slider 200 can be installed in the perforated guide rail 100. When the switch 202 on the limiting slider 200 is pressed, the limiting rod 204 built into the limiting slider 200 extends and can be locked into the positioning hole of the perforated guide rail 100, thereby fixing the fixture on the guide rail. The sample 500 is connected through the telescopic rod 402 of the connector 400. The number of samples 500 is determined according to production needs. The length of the telescopic rod 402 can be adjusted to accommodate samples 500 of different sizes. The rotary motor 300 can rotate the sample 500. The adjusting bolt 4034 is connected to the movable clamping plate 40332. When the adjusting bolt 4034 is lowered, the movable clamping plate 40332 clamps downwards at the same time. The adjusting bolt 4034 can be used to adapt to samples 500 of different thicknesses. Operators can adjust and rotate the tooling according to actual production needs to allow excess solution to flow away, so as to avoid over-development or incomplete development and etching of the substrate surface, or to develop and etch the side patterns of products with side patterns. This application presents a common fixture for developing and etching DPC substrates. A rotary motor 300 drives the sample 500 to rotate via a connector 400 to adjust the angle of the sample 500. The guide rail is a perforated guide rail 100, and a limiting slider 200 is slidably connected to the perforated guide rail 100, thereby fixing the fixture on the perforated guide rail 100 and adjusting the fixture spacing. Multiple samples 500 can be connected by adding or removing the connector 400 to meet the actual needs of the production line. The connecting part includes a telescopic rod 402, the length of which can be adjusted to accommodate samples 500 of different sizes. By adjusting the bolt 4034 and the clamp 4033, the movable clamp 40332 moves up and down with the adjusting bolt 4034. When the adjusting bolt 4034 is lowered, the movable clamp 40332 clamps down simultaneously, which can accommodate samples 500 of different thicknesses.

[0051] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
