“Tectonic Shift to System-Oriented Test - Be Ready or Be Left Behind”
“向以系统为导向进行测试的构造转变--不进则退”
Harry Chen
MediaTek Inc.
Abstract (English)

With the slowing of Moore's Law, advances in packaging and chiplet technology have stepped in to continue the drive towards ever higher levels of integration. What continues unabated is the increasing complexity of realized end products and systems. Electronics is becoming pervasive in and around all aspects of our lives. As a result, beyond quality, assurances of reliability, safety, and security are drawing attention in many new application domains from electric cars to smart factories. In light of these trends, current testing methodologies and practices face daunting challenges. Thorough testing of individual components and their structural interconnects can no longer guarantee the required levels of quality and reliability of the integrated system. In this talk, I will delve into aspects of the challenges now arising, discuss how testing has to shift to a system-oriented perspective, describe what that means in terms of specific enabling capabilities, and highlight recent developments in support of this paradigm shift.

摘要 (Chinese)

随着摩尔定律的放缓,封装和chiplet技术上的进步已经在推动着更高水平的集成。日益复杂的终端产品和系统有增无减。电子产品在我们生活中无处不在。也因此,除了质量之外,可靠性、安全性和安全保障等正受到来自新的应用领域的关注,从电动汽车到智慧工厂。在此趋势下,当前的测试方法和实践也面临着艰巨的挑战。对单个组件及其结构互连的测试方式已经无法再保证集成系统所需的质量和可靠性水平。在本次演讲中,我将深入探讨目前出现的挑战各个方面,讨论测试应该如何转变为面向系统的视角,描述其在这方面赋能的意义,并重点介绍下支持这种范式转变的最新进展。

Abstract - Biography (English)

With the development of 5G and automated driving technology, the chip develops towards high-speed and miniaturization. Traditionally, there are 2 ways to test high speed IC: socket with very short spring probe and Coaxial socket; short spring probe can’t provide enough test force, the performance is unstable, Coaxial socket is expensive. So, they are not the optimal solution to test QFN, QFP, SOIC and TSPO chips.

A super short Scrubbing contact(J shaped)is developed for QFN, QFP, SOIC and TSOP chips test. It provides short signal path by optimize pin shape, by this way, it provides great signal integrity: insertion loss: 20GHz @ <-1 dB; current carrying capacity :8Amps. J shaped Scrubbing pin secures to socket using an elastomer, ensure socket can provide stable test force in large temperature range with long cycle life, low and stable resistance at small pitch.

J shaped Scrubbing pin with special shape design, from rest to test, scrubbing action ensure minimal impact on PCB pad and package pad .The GND solution in socket can provide excellent thermal performance and impedance control, It also enables longer compliance similar to a spring pin. The socket concept allow field repairable without removing socket from PCB, reduced downtime.

This paper will share the how does J shaped scrubbing pin worked, the Mechanical and Electrical properties of J shaped Scrubbing contact. What’s the challenge in J shaped Scrubbing pin test and how to meet higher speed requirement in tighter pitch?

摘要 - 简介 (Chinese)

随着5G和自动驾驶技术的发展, 芯片朝着高速和小型化发展,通常用两种方式可以测试高速芯片:使用测试长度很短的弹簧探针和同轴测试插座。这两种测试方法各有有缺点:使用短的弹簧探针插座价格便宜但是由于真太短不能提供足够的力使针尖穿破引脚氧化层,测试不稳定;同轴结构的测试插座有很好的高频性能,也能提供很好的接触力,但是价格贵,交期长。因此这两种方式都不是测试QFN, QFP, SOIC和TSPO 封装的最佳选择。

研发一种超短型刮擦测试探针(J 型)用来测试QFN, QFP, SOIC 和TSOP 封装. 它优化的外形为信号提供了超短的路径,通过这种方法很好的保证信号的完整性: insertion loss: 20GHz @ <-1 dB; current carrying capacity :8Amps. J型刮擦探针通过橡胶条固定在测试插座上,可以保证测试插座在很宽的温度范围内,保持稳定的测试力和长久的循环寿命,在小间距的情况下仍可以提供稳定的,非常低的阻值。

J型刮擦探针有特殊的外形,确保从自由状态到测试状态,刮擦动作对PCB和芯片Pad影响降到最小。测试插座的接地解决方案可以提供极佳的散热和阻抗匹配。

这篇文章将分享J型刮擦探针是如何工作的,它的机械及电性能。在高速和小间距pad中,J型刮擦探针面临的挑战是什么。

Abstract - Biography (English)

Antenna in package(AIP) modules are manufactured in high volume due to its use in mobile phone that support 5G FR2.

These modules have no access to its mmWave transceiver other than via its antenna build into its package.

Over-the-air(OTA) testing by using the AIP’s antenna is necessary to evaluate the module’s mmWave performance.

Validation of AIP or antenna using OTA testing have been done for decades. However, implementing mmWave OTA testing in a high volume manufacturing (HVM) production is fairly current.

The current conventional semi-conductor test setup in production are inadequate for mmWave OTA testing.

Some of the unique OTA requirements such as mmWave testing requirements, special made mmWave antenna for handlers/sockets and handling of device without blocking its antenna are not available in current HVM production floor.

This presentation will introduce OTA testing and the challenges of doing it in a HVM environment.

Some general solution will be also be highlighted

Frank Goh is a principal application consultant in the wireless center of expertise for Advantest. For more than 20 years, he has been developing test applications from mmWave, RF, mix-signal to DC. For the past few years, he is working more on mmWave 5G applications and OTA testing. Frank has an Engineering degree as well as Master of Science degree from National University of Singapore.

摘要 - 简介 (Chinese)

5G的FR2 采用了毫米波频段,在这个频段,天线尺寸足够小,可以做到芯片封装中形成了AIP(Antenna in package)。目前5G手机的商用进入成熟阶段,相应的AIP模块也需要大规模量产。

在测试中,AIP模块的信号只能通过内置天线直接在空气中传播,而非射频线缆进行传输,这样的 方法称为OTA(over the air)测试。

很多年前,OTA测试方法已经被采用,用作测试和评估模块的mmWave毫米波频段的性能。但是并没有作为大规模量产的手段。目前5G毫米波频段的大量应用,以及AIP封装的成熟,使得OTA第一次要用于大规模量产级别的半导体测试和生产。对于业界,这还是全新的挑战,相关应用还在探索和成熟的过程中。

测试生产中,有很多新的要求,例如为了和AIP模块建立射频通信信道,半导体量产环境需要进行相应的特殊设计。毫米波天线需要集成到handler和sockets中去,生产中如何不干扰AIP模块和测试环境间的OTA射频通信,等等。

本文将针对这些量产环境中的OTA测试方案和全新挑战,进行介绍。并且着重对一些通用方案进行讨论。

Abstract - Biography (English)

"For years Pick-and-Place test handling solutions have been the state-of-the-art technology for MEMS sensor handling in Final Test. Today, increasingly demanding test requirements for sensors and ever shrinking device sizes, introduce more and more challenges to this approach. This talk explores how Wafer-Level Final Test solutions for suitable packages like LGA’s, QFN’s, BGA’s, Fan-Out and WL-CSP’s help to overcome these challenges and improve overall process yield and Cost of Test.

By the example of magnetometer sensors, where CSP type packages are increasingly seen in the marketplace, we explore how Wafer Level Final Test can reduce the overall number of pick-and-place steps in Final Test, reduce conversion time and tooling cost for new packages, resulting in the above-mentioned yield increase and Cost of Test reduction.

Furthermore, improved magnetic stimulus options available for Wafer Level Final Test allow a more accurate calibration of sensors, adding even more value to this innovative test approach."

“Application of Deep Learning on Shmoo Data Result Analysis”
“深度学习在Shmoo数据结果分析中的应用”
Chao Zhou
Teradyne
Abstract - Biography (English)

Shmoo plot is a common method in the field of semiconductor testing to verify whether the specification of product can meet target or not. Shmoo plot analysis is also an important way to help test engineer to debug testing vector/pattern to find out the potential problem in chip design. What is more, the result of Shmoo plot analysis can benefit the yield ratio. This method always exams the characterization from the aspect of supply voltage and operating frequency. However, the review work of Shmoo plot result is managed manually, especially in the process of ATE test. As the chip become more and more complex, the amount of Shmoo plot in a single project become so large that much more time is spent on this part, hence extend the testing period, which impact the time to market. In this paper, a Shmoo result analysis tool based on deep learning is introduced, which can help to analyze the Shmoo result automatically in a short time with high test accuracy. This tool is developed under Python and PyTorch. My efficient tool is designed based on AlexNet with modification which adapt to the characteristics of Shmoo. These modifications can be benefit to the test accuracy eventually. In addition to the realization of the basic good and bad (Pass/Fail) second-class judgment, four labels have been added: Hole, Voltage Wall, Frequency Wall and Marginal to indicate the specific results of Shmoo.

Chao Zhou is a field application engineer in Teradyne Shanghai. He has been 8 years in Teradyne with major activity in SOC testing solution development and data analysis.

摘要 - 简介 (Chinese)

Shmoo是半导体ATE测试领域常用的一种验证产品的规格是否符合目标的方法。Shmoo分析也同样是帮助测试工程师调试测试向量,以找出芯片设计中的潜在问题的重要方法。这种方法总是从电源电压和工作频率方面进行特征分析。利用Shmoo来分析结果的最终目的是帮助提高成品良率。然而,特别是在ATE测试过程中,对Shmoo结果的分析工作往往都是手动完成的。随着芯片变得越来越复杂,单个项目中的Shmoo图量变得非常巨大,以至于更多的时间需要花在这部分,拖长了测试周期,影响了上市时间。本文介绍了一个基于深度学习的Shmoo结果分析工具,它可以帮助在短时间内自动分析Shmoo结果,并具有较高的测试精度。这个工具是基于PyTorch开发的,神经网络的结构是基于AlexNet设计的,并根据Shmoo的特点进行了优化。这些修改最终会有助于提高分析预测的准确性。除了实现基本的好和坏(Pass/Fail)的二类判断外,还增加了四个标签:Hole、Voltage Wall、Frequency Wall和Marginal,表示Shmoo的具体结果。

Abstract - Biography (English)

EV works with power battery. And power batteries must be monitored, that is battery monitor system (BMS). The responsibilities of BMS include battery capacity, charge and discharge control, real-time monitoring of battery safety status, and so on.

Now, people have the increase in the endurance requirements of EV cars, combined with the iteration of fast charging technology. That means the trend of BMS devices will be a single chip that can monitor much more series-connected battery packs, with higher voltage accuracy monitoring requirements. At the same time, BMS should response quickly during cells balancing. For example, the x16-cells analog front-end (AFE) chip should be tested on 80V range, and x24 AFE should be tested on 120V range. Each cell needs a monitoring pin that means standalone test channels should be arranged to each pin to simulate battery cell status. For more accurate monitoring of batteries status, the high precision ADCs what are the core units in AFE has more than 12-bits, and LSB may be less than 100uV. In terms of battery balancing, much more AFE integrated balancing MOSFET. So Rdson should be tested when high voltage is forced. In general, this requires a transient current of several amperes.

This paper will focus on how to achieve high voltage excitation, high accuracy ADC measure, and transient high current measurement in single test flow.

Kun Xu, a business development expert of Advantest (China), focuses on automotive electronics market research, testing solution design of automotive chips, etc. He familiars with various related testing processes including AEC-Q100. Kun Xu has more than 15 years of experience in semiconductor device testing, takes many test solution development and implementation, such as MCU, application processor, baseband, complex PMIC, RF devices, and so on.

摘要 - 简介 (Chinese)

新能源汽车离不开动力电池,而动力电池离不开电池监控系统BMS。电池的电量监控、充放电控制、电池安全状态的实时监控,都是BMS芯片的工作职责。 随着大众对新能源车续航要求的提升、快充技术的迭代等,BMS芯片的发展趋势将是单颗芯片可以监控更多的串联电池组,监控电压精度要求更高,监控间隔时间更短,电池平衡反应更快。这些新的技术趋势对BMS芯片的测试也提出了更高的要求。例如,16节串联BMS中,模拟前端芯片要求80V的测试条件, 24节BMS则需要120V测试条件;每个电芯节点都有监控引脚,需要独立测试通道加载可调节电压,用来模拟电池状态。为了更加精准的监视电池的状态,作为模拟前端核心的高精度ADC,其位数超过12bit,LSB可达100uV以下。在电池平衡方面,越来越多的BMS模拟前端芯片集成了放电MOS管,所以需要在大电压测试MOS管的Rdson。而这通常需要几个安培的瞬态电流。 本文将聚焦于如何在一个测试流程中,实现高压激励、高精度直流量测、瞬态大电流测试等要求。
