Terminals are where the datasheet meets the real assembly line, and the choice between press-fit pins, screw terminals and solder pins affects PCB design, production yield, serviceability and long-term reliability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This article explains how each terminal type works, where it is typically used, and what to check before you commit a design. It is written for engineers selecting <a href=\"https:\/\/www.hiitiosemi.com\/product-category\/igbt-module\/\">IGBT<\/a> y <a href=\"https:\/\/www.hiitiosemi.com\/product-category\/sic-module\/\">m\u00f3dulos SiC<\/a> for inverters, drives and power conversion systems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where Each Terminal Type Sits in a Module<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most industrial module packages use more than one terminal type at once. The high-current power terminals (DC+, DC\u2212, phase output) and the low-current auxiliary pins (gate, emitter sense, NTC) have different jobs, so they are often built differently.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Infineon\u2019s EconoDUAL 3 mounting note is a clear example: the power terminals are screw terminals for busbar connection, while the auxiliary terminals are available as either solder-only pins or PressFIT pins (<a href=\"https:\/\/www.infineon.com\/assets\/row\/public\/documents\/60\/42\/infineon-an2006-05-mounting-instructions-econodual-3-applicationnotes-en.pdf\" target=\"_blank\" rel=\"noopener\">Infineon AN2006-05<\/a>). PCB-mounted families such as Easy modules offer solder pins alongside standard and high-current PressFIT pins (<a href=\"https:\/\/www.infineon.com\/assets\/row\/public\/documents\/60\/42\/infineon-an2023-07-assembly-instructions-for-the-easy-modules-applicationnotes-en.pdf\" target=\"_blank\" rel=\"noopener\">Infineon AN2023-07<\/a>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">HIITIO Semi supplies modules in these same industry package families, including Easy 2B\/3B, Econo Dual 3, Econo PIM and 62 mm. The exact terminal construction of each part is defined in its datasheet, so it should be confirmed against the datasheet before layout begins.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Press-Fit Pins<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A press-fit pin is pressed into a plated through-hole in the PCB without solder. The pin is designed so that its contact zone deforms to form a gas-tight, solderless connection with the hole wall. The relevant general standard is IEC 60352-5, \u201cSolderless connections \u2013 Part 5: Press-in connections,\u201d which is cited in both the ZVEI press-fit recommendations and Infineon\u2019s application notes.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"900\" height=\"550\" src=\"https:\/\/www.hiitiosemi.com\/wp-content\/uploads\/2026\/11\/Press-Fit-3.webp\" alt=\"\" class=\"wp-image-6475\" srcset=\"https:\/\/hiitiosemi.b-cdn.net\/wp-content\/uploads\/2026\/11\/Press-Fit-3.webp 900w, https:\/\/hiitiosemi.b-cdn.net\/wp-content\/uploads\/2026\/11\/Press-Fit-3-300x183.webp 300w, https:\/\/hiitiosemi.b-cdn.net\/wp-content\/uploads\/2026\/11\/Press-Fit-3-768x469.webp 768w, https:\/\/hiitiosemi.b-cdn.net\/wp-content\/uploads\/2026\/11\/Press-Fit-3-18x12.webp 18w, https:\/\/hiitiosemi.b-cdn.net\/wp-content\/uploads\/2026\/11\/Press-Fit-3-600x367.webp 600w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What works well<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>No soldering step.<\/strong> There is no reflow or wave exposure for the module, and the press-in operation is a single mechanical step. Infineon specifies a press-in speed of 25 to 100 mm\/min per IEC 60352-5 for EconoDUAL 3.<\/li>\n\n\n\n<li><strong>Repeatable joints.<\/strong> The connection is defined by pin geometry and hole quality rather than by solder wetting.<\/li>\n\n\n\n<li><strong>Limited rework.<\/strong> Infineon states that a PressFIT module can be replaced up to two times, so a PCB can be used three times in total.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What to watch<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>PCB hole quality is decisive.<\/strong> For Easy modules, Infineon specifies a 1.15 mm drill (minimum 1.12 mm, not milled), 25\u201350 \u00b5m copper in the hole, maximum 15 \u00b5m tin, and a final hole diameter of 0.99\u20131.09 mm. The ZVEI paper notes that the press-fit requirements must be agreed with the PCB manufacturer in advance because they can add cost and effort to board production.<\/li>\n\n\n\n<li><strong>Surface finish matters.<\/strong> ZVEI lists HAL, lead-free HAL and immersion tin as having good slippage properties for press-in.<\/li>\n\n\n\n<li><strong>Pin current is limited by the pin and the board.<\/strong> For Easy modules, Infineon rates a standard PressFIT pin at up to 25 A and a high-current pin at up to 50 A nominal. These figures are specific to that product family and should not be assumed for other packages.<\/li>\n\n\n\n<li><strong>Mechanical loading.<\/strong> Infineon limits the force on each pin to 6 N and total pulling force on the module to 20 N, so the PCB must be supported appropriately.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Screw Terminals<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Screw terminals clamp a busbar or cable lug directly onto the module\u2019s power terminal. They are the standard solution where currents are too high for PCB pins, which is why they are common on 62 mm, Econo Dual and larger packages.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What works well<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>High current paths.<\/strong> A busbar bolted to the terminal avoids routing hundreds of amperes through a PCB.<\/li>\n\n\n\n<li><strong>cURL Too many subrequests by single Worker invocation.
