Stamp hole module radio frequency test PAD layout structure and radio frequency test fixture thereof

Abstract

The invention discloses a stamp hole module radio frequency test PAD layout structure and a radio frequency test clamp thereof. The plate edge of a stamp hole module is provided with a plate edge PIN,the stamp hole module comprises a radio frequency antenna PIN serving as an antenna radio frequency test point and a ground PAD bonding pad, the A end of the radio frequency antenna PIN is located onthe plate edge, and the B end of the radio frequency antenna PIN is located in the center of the ground PAD bonding pad; the ground PAD bonding pad is a cutting annular bonding pad; the cutting edgeof the cutting annular bonding pad faces the direction of the board edge where the board edge PIN is located; the radio frequency test fixture comprises a radio frequency test needle and a test needleplate sleeve; the radio frequency test pin comprises an outer ring shielding PAD which is used for being electrically connected with the ground PAD bonding pad and is matched with the ground PAD bonding pad in shape; and the test needle plate sleeve is used for fixing and limiting the radio frequency test needle. According to the invention, through the distance between the radio frequency test point PAD and the radio frequency antenna PAD, the length of a radio frequency wire is reduced, the radio frequency performance is improved, and the waste in production is avoided. Meanwhile, the radiofrequency test needle is correspondingly in contact with the ground PAD bonding pad after metal cutting to obtain the radio frequency test fixture.

Description

technical field [0001] The invention relates to the technical field of application terminals in the communication module industry, and more specifically relates to a stamp hole module radio frequency test PAD layout structure and a radio frequency test fixture thereof. Background technique [0002] At present, in the production of all stamp hole communication modules, the radio frequency needs to be pre-calibrated. Generally, the PAD at the bottom of the module has a radio frequency test point reserved, which is connected to the radio frequency test pin on the production fixture for calibration and comprehensive testing. The central test point of the RF test needle is connected to the RF antenna PIN on the module, and the metal shielding PAD around the RF test needle is connected to the ground PAD around the antenna PIN on the module to maintain good RF performance. [0003] However, for the existing RF test pin structure, there are two common methods for the layout of the P...

Problems solved by technology

[0003] However, for the existing RF test pin structure, there are two common methods for the layout of the PAD at the bottom of the module: the first layout method discards the module PIN, and sets the center point of the PIN on the RF antenna pad of the module as the center, and sets around it. A circle of PAD pads is in contact with the shielding PAD of the outer ring of the test pin. The disadvantage is that the two module PINs around the center point of the RF antenna pad PIN of the module will be discarded, causing some waste; the second type of center test Point extension layout method, on the basis of method 1, the RF calibration antenna test point is moved up, and with this test point as the center, a circle of ground PAD pads is set around it, which is in contact with the outer ring shielding PAD of the test pin , although it will not occupy the space of the PIN pin, its disadvantage is that there will be a period of antenna tail difference in the formal application of the module, which will slightly affect the RF performance
