Our conclusion was that data sheet values are only meaningful when comparing products under identical, static conditions. Even accelerated testing rarely reflects real-world application scenarios, and field return rates can vary too widely to apply universally. We also cautioned that a finite operational lifetime due to wear-out does not necessarily indicate poor reliability during that period.<\/p>\n\n\n<div id=\"id_69d8f43bf18ab\" class=\"media block\">\n\t<div class=\"container media-left content-top\">\n\t\t<div class=\"media\" style=\"left: 0px; min-width: 408px; max-width: 408px;\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"image none\">\n\t\t\t\t\t\t\t<img decoding=\"async\" alt=\"MTBF reliability graphic featuring circular icons representing uptime, failure response, monitoring, and system performance on a blue technology-themed background.\" src=\"https:\/\/flex.com\/wp-content\/uploads\/2025\/05\/MTBF_2025-05-26-083427_gklz-e1757446122377-1200x947.jpg\" title=\"\">\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<div class=\"content\" style=\"margin-right: 0px; margin-left: 36px;\">\n\t\t\t\t\n\n<p>In practice, power electronic modules from reputable manufacturers are highly reliable when operating under stable conditions, even at high temperatures.<\/p>\n\n\n\n<p>Often, accelerated reliability tests performed on modules terminate without a single failure.

These could be shock, vibration, electrical transients, and ESD events, but in a professional application such as a data center, these effects can be identified and eliminated. However, one effect that cannot be prevented is temperature swings, which cause differential expansion and contraction of interfacing materials in the module and its terminations, and the possibility of condensation and resulting corrosion. The swings could be due to changes in ambient temperature, but the common cause is unavoidable self-heating and cooling after large load steps. Modern power converter designs can be very efficient, but customers leverage this to extract more power from smaller module form factors, so changes in dissipation and internal temperatures with load steps can still be large.<\/p>\n\n\n\n<p>The situation is not helped by the drive to reduce average power consumption by switching processors to an \u2018idle\u2019 mode whenever possible. This approach, while effective, comes with its own set of additional complications. Sudden transitions from near-zero to hundreds of amps load and back again not only challenges a power module to maintain output voltage within specification but also generates rapid internal temperature swings that can lead to long-term mechanical stress and damage.<\/p>\n\n\n\t\t<\/div>\n\t\t<div class=\"sidebar normal-column\">\n\t\t\t\t\t\t\t\t\t<div class=\"post\">\n\t\t\t\t\t\t\t\t<a title=\"Thermal model BMR316\" class=\"image\" href=\"https:\/\/flex.com\/downloads\/thermal-model-bmr316\" target=\"_self\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" alt=\"Thermal model BMR316\" src=\"https:\/\/flex.com\/wp-content\/uploads\/2026\/04\/TM-BMR316-540x304.png\" title=\"\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"label\">\n\t\t\t\t\t\t\tThermal Model\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t<a title=\"Thermal model BMR316\" class=\"title\" href=\"https:\/\/flex.com\/downloads\/thermal-model-bmr316\" target=\"_self\">\n\t\t\t\t\tThermal model BMR316\t\t\t\t<\/a>\n\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"post\">\n\t\t\t\t\t\t\t\t<a title=\"Spare parts logistics:\u00a0Right parts, right place, right time\" class=\"image\" href=\"https:\/\/flex.com\/zh\/resources\/spare-parts-logistics\" target=\"_self\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" alt=\"Employees wearing high-visibility vests in an inventory warehouse moving spare parts on a dolly\" src=\"https:\/\/flex.com\/wp-content\/uploads\/2026\/03\/Product-Distribution-Logistics-Center-warehouse-540x304.jpg\" title=\"\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"label\">\n\t\t\t\t\t\t\tSolution Brief\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t<a title=\"Spare parts logistics:\u00a0Right parts, right place, right time\" class=\"title\" href=\"https:\/\/flex.com\/zh\/resources\/spare-parts-logistics\" target=\"_self\">\n\t\t\t\t\tSpare parts logistics:\u00a0Right parts, right place, right time\t\t\t\t<\/a>\n\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"post\">\n\t\t\t\t\t\t\t\t<a title=\"Powering data centers from grid to chip\" class=\"image\" href=\"https:\/\/flex.com\/downloads\/powering-data-centers-from-grid-to-chip\" target=\"_self\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" alt=\"Powering data centers from grid to chip\" src=\"https:\/\/flex.com\/wp-content\/uploads\/2026\/02\/2024-Power-Brochure_DIGITAL-cover-540x304.jpg\" title=\"\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"label\">\n\t\t\t\t\t\t\tBrochure\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t<a title=\"Powering data centers from grid to chip\" class=\"title\" href=\"https:\/\/flex.com\/downloads\/powering-data-centers-from-grid-to-chip\" target=\"_self\">\n\t\t\t\t\tPowering data centers from grid to chip\t\t\t\t<\/a>\n\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t<\/div>\n<\/div>\n\n<div id=\"id-69d8f43c0ed56\" class=\"box block full-width dark-content zh \" style=\"background-color: transparent; background-image: none;\">\n\t<style>\n\t\t#id-69d8f43c0ed56 > .container > .content {\n\t\t\tbackground-color: transparent;\n\t\t\tposition: relative;\n\t\t\tpadding-top: 36px;\n\t\t\tpadding-right: 0px;\n\t\t\tpadding-bottom: 96px;\n\t\t\tpadding-left: 0px;\n\t\t\tmargin-left: 0px;\n\t\t\tmargin-right: 0px;\n\t\t}\n\t\t@media (max-width: 1272px) {\n\t\t\t#id-69d8f43c0ed56.box.block.full-width > .container > .content {\n\t\t\t\tpadding-left: 0 !important;\n\t\t\t\tpadding-right: 0 !important;\n\t\t\t\tmargin: 0 !important;\n\t\t\t}\n\t\t}\n\t\t@media (max-width: 960px) {\n\t\t\t#id-69d8f43c0ed56 > .container > .content {\n\t\t\t\t\/\/padding-top: 18px;\n\t\t\t\tpadding-right: 0px;\n\t\t\t\t\/\/padding-bottom: 48px;\n\t\t\t\tpadding-left: 0px;\n\t\t\t}\n\t\t}\n\t<\/style>\n\t<div class=\"container\">\n\t\t<div class=\"content\">\n\t\t\t\n\n<h2 class=\"wp-block-heading has-medium-font-size\" id=\"h-cte-mismatch-is-an-inherent-problem\" style=\"font-style:normal;font-weight:600\">CTE mismatch is an inherent problem<\/h2>\n\n\n\n<p>If all the materials within a power module \u2014 extending through its connections to the circuit board and heatsink \u2014 were homogenous, temperature swings would pose little stress. In reality, however, the materials in the thermal path in a typical module include a mix of materials such as silicon, copper, ceramic, fiberglass, aluminum, solder, and others. Encapsulant around the internal components might be present, squeezing and pulling. The materials all have differing Coefficients of Thermal Expansion (CTE), which is the ratio that a material\u2019s linear dimension changes with temperature, usually stated in units of micrometers per meter per degree Kelvin (\u00b5m\/m.K). Aluminum for example, has a CTE of about 23 \u00b5m\/m\u00b7K, while at the other extreme, a silicon die has a value of about 3. For example, with a 100\u00b0C temperature change \u2014 a realistic scenario for a power semiconductor \u2014 the aluminum bond wire attachment area expands about eight times more than the silicon die beneath it. This equates to a dimensional change of approximately 2.3 \u00b5m compared to just 0.3 \u00b5m over a 1 mm length.<\/p>\n\n\n\n<p>The latest DC\/DC module power switches are often wide band-gap silicon carbide or gallium nitride types. While their CTEs are higher than silicon, around 4 and 5 respectively, at least they are closer in value to the materials they typically interface with.<\/p>\n\n\n\n<div id=\"id-69d8f43c0a0ef\" class=\"columns-grid block\">\n\t<style>\n\t\t\/* === Frontend Grid === *\/\n\t\tbody:not(.block-editor-page) #id-69d8f43c0a0ef > .container {\n\t\t\tdisplay: grid;\n\t\t\tgrid-template-columns: 1fr 2fr;\n\t\t\tgap: 48px;\n\t\t}\n\t\t\n\t\t\/* Column padding *\/\n\t\t#id-69d8f43c0a0ef .column,\n\t\t#id-69d8f43c0a0ef .wp-block-acf-column {\n\t\t\tpadding: 0;\n\t\t}\n\t\t\n\t\t\/* Rules between columns *\/\n\t\t#id-69d8f43c0a0ef > .container.show-rules .column + .column,\n\t\t#id-69d8f43c0a0ef > .container.show-rules .wp-block-acf-column + .wp-block-acf-column {\n\t\t\tborder-left: 1px solid rgba(38, 38, 38, 0.2);\n\t\t}\n\t\t\n\t\t\/* Max width for nested widgets *\/\n\t\t#id-69d8f43c0a0ef .column .code.block .container .tagembed-widget,\n\t\t#id-69d8f43c0a0ef .wp-block-acf-column .code.block .container .tagembed-widget {\n\t\t\tmax-width: 600px;\n\t\t}\n\t\t\n\t\t\/* === Editor Overrides === *\/\n\t\tbody.block-editor-page #id-69d8f43c0a0ef > .container > .block-editor-inner-blocks > .block-editor-block-list__layout {\n\t\t\tdisplay: grid !important;\n\t\t\tgrid-template-columns: 1fr 2fr !important;\n\t\t\tgap: 48px !important;\n\t\t}\n\t\t\n\t\tbody.block-editor-page #id-69d8f43c0a0ef .wp-block-acf-column {\n\t\t\twidth: 100% !important;\n\t\t\tbox-sizing: border-box;\n\t\t}\n\t\t\n\t\t\/* Mobile responsiveness *\/\n\t\t@media (max-width: 1320px) {\n\t\t\t#id-69d8f43c0a0ef > .container {\n\t\t\t\tdisplay: block !important;\n\t\t\t\tmax-width: 600px;\n\t\t\t}\n\t\t\t#id-69d8f43c0a0ef > .container > .column,\n\t\t\t#id-69d8f43c0a0ef > .container > .wp-block-acf-column {\n\t\t\t\tpadding: 36px 0 0 0 !important;\n\t\t\t}\n\t\t\t#id-69d8f43c0a0ef > .container > .column:first-child,\n\t\t\t#id-69d8f43c0a0ef > .container > .wp-block-acf-column:first-child {\n\t\t\t\tpadding: 0 !important;\n\t\t\t}\n\t\t\t#id-69d8f43c0a0ef > .container.show-rules .column + .column,\n\t\t\t#id-69d8f43c0a0ef > .container.show-rules .wp-block-acf-column + .wp-block-acf-column {\n\t\t\t\tborder-left: none;\n\t\t\t\tborder-top: 1px solid rgba(38, 38, 38, 0.2);\n\t\t\t\tpadding: 30px 0 0 0 !important;\n\t\t\t\tmargin-top: 30px;\n\t\t\t}\n\t\t}\n\t<\/style>\n\t<div class=\"container align-center\">\n\t\t\n<div class=\"column block\">\n\t\n\n<p>For high power density DC\/DCs, these switches are now almost exclusively ball-grid or land-grid array packaging, rather than traditional leaded types, which previously offered some degree of mechanical stress relief across one of the larger CTE mismatches \u2014 from lead frame through the solder to the copper traces.

Thermal shock tests push this further, often reaching around 40\u00b0C per minute. While such tests are standard for independent agencies, a more realistic approach is to simulate the actual end-use environment. In data center applications, for example, ambient temperatures tend to remain stable, while load levels fluctuate with defined patterns, ramp rates, and repetition. It\u2019s clear that the thermal stress effects from this approach would be quite different from those caused by a fixed load and varying ambient temperature.<\/p>\n\n\n\n<p>Flex Power Modules designs its power modules to minimize issues related to CTE mismatch and conducts thermal testing based on typical market conditions.
