Flexibility of Multilayer Ceramic Capacitors: Guaranteed 5mm of bend on AEC-Q200 Certified Components

时间： 2024-06-19 来源：Knowles Official Website

技术问答

Today, with the continued drive for more technical features in conventional cars and the increasing electrification of the drive train, the challenges facing electronics designers are ever increasing. Alongside a drive to lower costs and smaller form factors, MLCCs（Multilayer Ceramic Capacitors）are being used in ever harsher applications and in ever increasing numbers. This is driving board population density upwards and with it concerns for reliability and particularly the likelihood of mechanical cracking. Thus electronic designers are now demanding flexibility that exceeds the current Automotive Electronic Council bend test specification (AEC-Q200 Rev D June 1, 2010).

The international requirement for bend testing is referred to in several different specifications:

●IEC 60384-1:2001 Fixed capacitors for use in electronic equipment Part 1: Generic Specification section 4.35 Substrate bending test refers to IEC 60068-2-21.

●IEC 60068-2-21: 2006 Environmental testing: Test U: Robustness of Terminations and Integral Mounting Devices. Section 8 test Ue specifies the test required to assess the mechanical robustness of surface mounting device terminations when mounted on a substrate. Test Ue1 specifies the substrate bend test. IEC 60068-2-21 refers to requirements such as deflection and acceptance criteria as being included in the “relevant specification”. Knowles Precision Devices maintains IECQ CECC (International Electrotechnical Commission Quality certification program - CENELEC Electronic Components Committee) product approval and the “relevant specification” is QC 32100-A001:2007

●QC 32100-A001:2007 Table 2 – Periodic Tests defines board flex minimum requirements as:

■Class I C0G/NP0 (1B/CG): All types. Class II X7R (2R1): Y and H only (FlexiCap™).3mm deflection Class I

■2mm deflection Class II

■X7R (non – FlexiCap™ termination) 1mm deflection

●AEC-Q200-005, Board Flex / Terminal Bond Strength Test.

■Minimum requirements stated in table 2 stress test reference 21: 2mm (min) for all except 3mm for Class I.

Knowles Precision Devices remains the front runner for Flexible termination having introduced the award winning FlexiCap™ technology to the market.

FlexiCap™ polymer termination with its fibrous structure effectively reduces the mechanical stress being exerted onto the ceramic section of the capacitor by approximately 50%. During FlexiCap trials, some 10 million polymer terminated Class II X7R (2R1) capacitors were supplied to customers for evaluation. The applications targeted were those known to have a long history of problems due to capacitor cracking. During the course of these trials, not a single part was identified to have failed as a result of chip fracture.

AEC-Q200 certified components terminated with FlexiCap™ have a higher resistance to mechanical cracking meeting the demand by electronic design engineers for components that far exceed the minimum industry standard for flexibility, enabling Knowles Precision Devices to offer a guaranteed 5mm bend test deflection on AEC-Q200 components exceeding all of the requirements touched on above.

To learn more about FlexiCap™ technology, mechanical cracking and how we test at Knowles Precision Devices please take a look at: Flexibility of Multilayer Ceramic Capacitors – Automotive-grade Multilayer Ceramic Capacitors with Mechanical Crack Resistance.

【经验】通孔插装技术(THT)对比表面贴焊技术(SMT)，为您的高可靠性应用选择适用的装配方案

印刷电路板（PCB）上元件的主流安装方式为通孔插装技术（THT）和表面贴焊技术（SMT）。近几十年中SMT是非常流行的安装方式，因此应用设计师往往将其设定为默认方式。但事实上这两种方案各有千秋，在高可靠性的应用设计中我们需要审慎选用。

【技术】一文了解陶瓷电容器需要纳入考量的重要因素——等效串联电阻

在理想状况下，电容器可被设计成无电阻的样式，然而，这在物理学上是不可能实现的，因为任何电容器都有某种类型的内阻与其形成类似串联的存在，这就是等效串联电阻（ESR）。其阻值会因电容器而异，具体取决于各项因素，包括所用的电介质材料、漏电流以及电容器的质量和可靠性。

The Role of EMI Filters in Power Electronics

EMI filters are designed to keep internally generated electrical noise from conducting across the system and negatively impacting operations elsewhere. In other words, they contain and manage noise. In power electronics, they take the form of power line filters that protect the line from upstream noise.

SLCs vs. MLCCs: Which Capacitor Type is Right for My Application?

One early decision that circuit designers must make is to determine if a single-layer capacitor (SLC) or multi-layer ceramic capacitor (MLCC) is the right fit for their application needs.
