Fifty thousand hybrid circuits of five different types will be manufactured for the Phase-2 Upgrade of the CMS Outer Tracker. These circuits must undergo a strict quality control process, composed of functional testing and visual inspection, before they can be assembled into modules. The hybrids will be functionally tested first at the manufacturing site. Afterwards, they will be visually inspected and functionally tested again at CERN or at collaborating institutes. Results from these processes will be stored in the CMS production database. This paper presents the software tools developed to carry out these tasks.

“…The test cards can be inserted into a crate, which houses three multiplexing backplanes, which in turn can accept four cards each. The electrical connection between the backplane and test card is realized with a connector compliant with the VITA 57.1 standard Low Pin Count FMC (LPC) connector definition [2]. By design only one test card can be active at a time, so the hybrids are tested in series.…”

Alongside the High Luminosity LHC upgrade, the silicon tracker of the CMS detector will be replaced within the scope of the so-called Phase-2 upgrade. The new tracker will consist of an inner part (Inner Tracker with pixelated modules) and at larger radii the Outer Tracker with two different module types (PS and 2S modules). One hybrid type used on these modules is the 2S service hybrid. It provides the optical link connection of a 2S module via the Low Power Giga Bit Transceiver (lpGBT) and a Versatile Transceiver Plus module (VTRx+). It is also responsible for the module power distribution. The different responsibilities of the hybrid require a complete testing, which is performed by a dedicated custom made test card. After a hybrid has been installed on the test card, all signal connections can be tested and verified. The test system is designed to handle a high throughput during mass production. The requirements and the design for the 2S service hybrid test card are presented together with testing results of the first final 2S service hybrid prototypes.

“…The production scale testing of CMS Outer Tracker hybrid circuits prompted the design of a crate-based test system [3], which can be divided into five main parts (figure 1): a computer running testing software, FC7 [4] FPGA cards to simulate and interpret signals, Test Crate with signal multiplexing boards (backplanes) to switch the connections between 12 test slots, test cards (TC) to operate hybrid-type specific functional tests, and, finally, various jumpers and adaptors to accommodate the 15 distinct hybrid variants. Overall, six types of test cards were designed and produced.…”

The Phase-2 Upgrade [1] of the CMS Outer Tracker [2] requires the production of 7608 Strip-Strip (2S) and 5592 Pixel-Strip (PS) modules, altogether incorporating 45 192 hybrid circuits of 15 design variants. The module design makes the potential repairs impractical; therefore, performing production-scale testing of the hybrids is essential. Accordingly, a scalable, crate-based test system was designed and manufactured, allowing for parallel, high-throughput testing. To reproduce the operating conditions, the system was integrated within a climate chamber, which required the development of a remote control interface and the calibration of thermal cycles. The results and lessons learned from the test system integration and commissioning will be presented.
