Impact of the Stress on Reference Voltage of Power SIP Chip Applied in 5G Based Station

2022 China Semiconductor Technology International Conference (CSTIC) (2021)

Qiong Jin Yang Chen Na Mei Xiangming Fang Tuobei Sun

The reliability problem of domestic self-developed chips restricts the wide application of electronic products. Most reliability problems are caused by stress, including residual stress before and after encapsulation and stress introduced during the reliability test. For power chip, the stress is the main cause of the drift of reference voltage test values or failure. In this paper, the effect of different factors of stress source on the reference voltage after temperature cycling test is analyzed through the encapsulation material, die thickness and design of key parameters of temperature cycling test, based on issues of reference voltage failure in the reliability process of power SIP chip, combined with the JEDEC standard.

Inverse Kinematic Analysis of General 5R Serial Robot Based on Linear Transformation

Lubin Hang Qiong Jin Ting-Li Yang

Abstract Based on the linear transformation theory, a general method for inverse kinematic analysis of 5R serial robots is proposed in this paper. Using this method, a polynomial equation, which contains only one variable and no extraneous roots, can be derived from 3 original kinematic equations, whereas the traditional method needs 4 equations. The assembly condition of 5R manipulator (5R loop) and its application in kinematic analysis are discussed. This assembly condition is very useful for finding 6R manipulator’s real configuration.

Optimized Double-Regional Filtering Algorithm on MRI Three-Dimensional Reconstructed Images for the Evaluation of Effects of Delivery on the Pelvis of Primiparas

Scientific Programming (2021)

Qiong Jin Mian Huang Jun Lin Shansan Wu Shen Zhang

This study was to explore the denoising and segmentation effect of dual-domain image denoising (DDID) algorithm, and the Galois field (GF) and nonlocal means (NLM) algorithms were introduced for comparative analysis. 40 primiparas in the hospital from January 2018 to January 2020 were divided into an experimental group (caesarean section (CS), group E) and a control group (vaginal delivery (VD), group C). The peak signal-to-noise ratio (PSNR) and segmentation parameters of DDID algorithm were compared with GF algorithm and NLM algorithm. It was found that the DDID showed higher overall accuracy (OA) and lower false positive rate (FPR) and false negative rate (FNR). The PSNR of DDID was higher than the other two algorithms. GF algorithm showed the highest edge retention index (ERI). The incidence of pelvic organ prolapse (POP) in group E and group C was 9/20 (45%) and 5/20 (25%), respectively, with extreme difference (

P < 0.05

). Evaluation of the effects of delivery on the pelvis of primiparas with MRI three-dimensional (3D) reconstructed images based on the optimized DDID showed a superior and stable denoising effect and good segmentation, so it was worthy of clinical promotion and application.

Di-μ-bromo-1:2κ⁴Br-bis(quinoline)-1κN,2κN-bis(triphenylphosphine)-1κP,2κP-dicopper(I)

Acta Crystallographica Section C Crystal Structure Communications (1998)

Qiong Jin De‐Liang Long Y.-X. Wang X. Xin

The crystal structure of the title complex, [Cu2Br2(C9H7N)2(C18H15P)2], has been determined by X-ray diffraction. The molecule possesses a crystallographic centre of symmetry in which the four-membered Cu2(μ-Br)2 ring is planar, as required by the symmetry, with a Br—Cu—Br angle of 95.83 (2)° and two Cu—Br distances of 2.520 (1) and 2.573 (1) Å. The long Cu⋯Cu distance [3.414 (1) Å] indicates the absence of direct bonding between the two Cu atoms. The coordination sphere of copper is a distorted tetrahedron, with the six angles around copper ranging from 95.83 (2) to 118.1 (1)°. The Cu—N and Cu—P distances are 2.065 (3) and 2.216 (1) Å, respectively.

Structure Synthesis of Parallel Manipulators With 3-Dimension Translation and 1-Dimension Rotation

Qiong Jin Ting-Li Yang

Based on the units of single-opened-chains, some topological characteristics of rank-degenerated parallel manipulators are revealed, and a systematic and effective new method for structure synthesis of parallel manipulators with 3-dimension translation and 1-dimension rotation is put forward in this paper. As a result, 50 new mechanisms are synthesized and classified. The method proposed in this paper is of universal significance and has been used for the structure synthesis of rank-degenerated parallel manipulators with other kinematics output types.
