Particle noise detection fixture, device and method

Abstract

A particle noise detection fixture, comprising a base, a clamping frame integrally formed with the base located on one side of the base, the clamping frame and the base enclose to form a cavity for accommodating the element to be detected body, the clamping frame is provided with a fastener mounting hole communicating with the cavity; a particle noise detection device including a particle noise detection fixture; a particle noise detection method, comprising: step a1. Detecting the excess in the circuit; Step a2. Capping the circuit tube cap of the circuit to be detected on the socket of the circuit to be detected without packaging; Step a3. Capping the circuit tube capped The circuit to be tested is fastened into the fixture; Step a4. Place the fixture on the particle noise tester for detection; the above particle noise detection fixture, device and method realize the pre-testing of the circuit to be tested before packaging.

Description

technical field [0001] The invention relates to the field of electronic product production, in particular to a jig, device and method for particle noise detection of electronic packaging products. Background technique [0002] The particle impact noise detection test is an effective means of redundant inspection, which is used to detect the redundant loose particles in the packages of electronic components such as integrated circuits, transistors, capacitors, and relays in aviation / aerospace / military fields. The principle is to use a vibrating table to generate a series of specified mechanical shocks and vibrations, through which the particles bound in the product (ie excess) are loosened, and then through a certain frequency of vibration, the excess is displaced in the system. The displacement process of the mobile excess in the product is a random combination process of the sliding process and the impact process of the excess relative to the product shell. During this pro...

Problems solved by technology

[0003] In the past, the particle noise control of electronic products focused on the detection of redundant residues in sealed circuits, and the detection of particle noise before circuit sealing could not be realized.

However, once the circuit is sealed, it cannot be disassembled (once it is disassembled, it becomes a waste product). Therefore, after the sealing of the circuit with an unsatisfactory excess control level, it often fails to pass the particle noise in the screening assessment. Detection and become waste products, thereby reducing the pass rate of products
