Description

Technical Field

[0001] This utility model relates to the field of radio frequency chips, and in particular to a convenient testing device for radio frequency chips. Background Technology

[0002] A radio frequency (RF) chip is an electronic component that converts radio signals into specific radio signal waveforms and transmits them via antenna resonance. It includes a power amplifier, a low-noise amplifier, and an antenna switch. The RF chip architecture consists of two main parts: a receiving channel and a transmitting channel. During the design and manufacturing process, RF chips may encounter various problems, such as unstable performance or abnormal operation. Through professional testing, these problems can be identified and resolved in a timely manner, ensuring that the RF chip can operate reliably and stably in practical applications.

[0003] For example, patent publication number CN215116507U describes a dynamic testing device for an RF front-end chip, including a spectrum analyzer, a base, a bottom cover, a top cover, and a positioning block mounted on the spectrum analyzer. The positioning block has a cavity in the center for accommodating the RF chip. In use, the RF chip is placed into the cavity of the positioning block, ensuring contact between the chip and a probe at the bottom of the cavity. The top cover is then secured by a gripping plate, pressing the chip firmly against the probe. The RF coaxial connector is then connected to the spectrum analyzer for testing. During use, tweezers or a vacuum pen are typically used to gently pick up or extract the RF chip. However, manual loading and unloading during this process is unstable and prone to dropping, resulting in poor convenience. Therefore, there is an urgent need to develop an RF chip testing device that improves the stability of loading and unloading the RF chip, prevents dropping, and enhances testing convenience. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing RF chip testing devices, which typically require tweezers or vacuum pens to gently pick up or suck up RF chips during use. The manual loading and unloading process is unstable and prone to dropping, resulting in poor convenience. The technical problem this invention seeks to solve is to provide an RF chip testing device that improves the stability of RF chip loading and unloading, prevents dropping, and enhances testing convenience.

[0007] The chip test socket has placement trays on both sides for placing the chip to be tested and the chip that has been tested; the base is also equipped with an auxiliary loading and unloading device for assisting in chip handling.

[0008] The auxiliary loading and unloading device includes two slide rails fixedly installed on both sides of the base; sliders are slidably mounted on the two slide rails; connecting blocks are fixedly mounted on the two sliders; connecting rods are fixedly mounted on the two connecting blocks; a guide slide shaft is provided between the two connecting rods, and the two sides of the guide slide shaft are fixedly connected to the two connecting rods respectively; a moving block is also slidably mounted on the guide slide shaft; a mounting frame is provided on the front side of the moving block, and a mounting groove is provided on the side of the mounting frame near the moving block, in which a sliding rod is fixedly mounted; the mounting frame is slidably mounted on the moving block through the provided sliding rod; a vacuum pen for picking up and placing RF chips is also installed at the front end of the mounting frame.

[0009] Furthermore, the upper surface of the base is provided with placement slots on both sides relative to the chip test socket; the placement tray is placed on both sides of the chip test socket through the placement slots, which facilitates the positioning of the placement tray and prevents the placement tray from sliding on the upper surface of the base plate.

[0010] Furthermore, the placement tray is provided with several placement slots for placing radio frequency chips at equal intervals; this facilitates the placement and testing of multiple radio frequency chips.

[0011] Furthermore, two guide shafts are provided between the two connecting rods; while guiding the moving block in a sliding manner, the moving block is also circumferentially limited to prevent the moving block from rotating or deviating.

[0012] Furthermore, the movable block is slidably mounted on the guide shaft via a linear bearing, ensuring smooth sliding of the movable block.

[0022] The chip test socket 3 is provided with a placement tray 4 on each side for placing the chip to be tested and the chip that has been tested; the base 2 is also provided with an auxiliary loading and unloading device 5 for assisting in picking up and placing the chip.

[0023] The auxiliary loading and unloading device 5 includes two slide rails 51 fixedly installed on both sides of the base 2; sliders 52 are slidably arranged on the two slide rails 51; connecting blocks 53 are fixedly installed on the two sliders 52; connecting rods 54 are fixedly installed on the two connecting blocks 53; a guide slide shaft 55 is arranged between the two connecting rods 54, and the two sides of the guide slide shaft 55 are fixedly connected to the two connecting rods 54 respectively; a moving block 56 is also slidably arranged on the guide slide shaft 55; a mounting frame 57 is arranged on the front side of the moving block 56, and a mounting groove is arranged on the side of the mounting frame 57 near the moving block 56, and a sliding rod 58 is fixedly arranged in the mounting groove; the mounting frame 57 is slidably mounted on the moving block 56 through the provided sliding rod 58; a vacuum pick-and-place pen 59 for picking up and placing radio frequency chips is also installed at the front end of the mounting frame 57.

[0024] Working principle:

[0025] This utility model relates to an RF chip testing device. In use, several RF chips to be tested are placed in a placement tray 4. The placement tray 4 is then placed on one side above the base 2, with an empty placement tray 4 for placing the tested RF chips on the other side. The operator then holds the upper end of a vacuum pen 59 and pushes it to the upper end of the RF chip in the placement slot of the placement tray 4. During the movement of the vacuum pen 59, the slider 52 moves smoothly forward and backward on the slide rail 51; the moving block 56 moves smoothly left and right on the guide shaft 55; and the sliding rod 58 on the mounting bracket 57 slides smoothly between the sliding rod 58 and the moving block 56, allowing the vacuum pen 59 to move smoothly up and down. When the vacuum pen 59 moves to… When the RF chip to be tested is placed above the slot in the placement tray 4, the vacuum pen 59 is lowered, and the mounting bracket 57 moves under the action of the slide bar 58, so that the suction cup at the lower end of the vacuum pen 59 is in contact with the upper surface of the RF chip. Then, the vacuum pen 59 is activated, so that the suction cup at the lower end of the vacuum pen 59 picks up the RF chip. Then, the vacuum pen 59 is moved up and then moved above the chip test holder 3. Then, the vacuum pen 59 is moved down, so that the RF chip is placed in the chip test holder 3. Then, the vacuum pen 59 releases the RF chip, so that the RF chip is placed in the test slot of the chip test holder 3. Finally, the vacuum pen 59 is moved to one side, the upper cover of the chip test holder 3 is closed, and the equipment is started to test the RF chip. After the test is completed, the RF chip is removed from the chip test holder 3 by the vacuum pen 59 and placed in the placement tray 4 on the other side.

[0026] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
