摘要

CMS 的 ECAL Barrel 和 MTD Barrel Timing Layer 子探测器已接近电子板(包括电压调节 PCB)的批量生产:分别为 LVR 和 PCC。将在大型强子对撞机 LS3 期间安装 2448 个 LVR 和 864 个 PCC。这些电路板上装有耐辐射的 bPOL12V ASIC,可将宽输入电压范围转换为微电子所需的 1.2-2.5 V 电压电平。每块板卡都必须在不同的生产阶段经过多次测试,以确保其符合要求。本文介绍了一种测试 bPOL12V 转换质量的方法,包括检测某些负载水平下的不稳定区域。

Universal test system for boards hosting bPOL12V DC-DC converters
The ECAL Barrel and MTD Barrel Timing Layer subdetectors of CMS are approaching series production of electronic boards, including voltage conditioning PCBs: LVRs and PCCs respectively. 2448 LVRs and 864 PCCs will be installed during LS3 of the LHC. These boards are hosting radiation-tolerant bPOL12V ASICs which convert a broad input voltage range into required voltage levels for microelectronics between 1.2–2.5 V. Each card must be tested multiple times at various production stages to ensure its conformity. This contribution describes a methodology of testing bPOL12V conversion quality including the detection of instability regions at certain load levels.
