In short, it is a term used to capture the multiple facets of <em>making design decisions for someone or something else<\/em>. Design For X. Where \u201cX\u201d is one of the following:<\/p><p class=\"\"><strong>Design for Manufacturability<\/strong> \u2013 Designing a component with electrical engineering solutions so that it can be manufactured or fabricated in an efficient and cost effective manner.<\/p><p class=\"\"><strong>Design for Assembly<\/strong>\u00a0\u2013 Designing an assemblage feature so that multiple components can be assembled together in a reliable and cost effective manner.<\/p><p class=\"\"><strong>Design for Testing<\/strong>\u00a0\u2013 Incorporating features to make it simple and efficient to test the functionality of a product in a timely and cost effective manner.<\/p><p class=\"\">Mature engineers and product developers recognize that it takes a village to go from prototype to product. There are multiple stages to DFx engineering and manufacturing and no one person can do them all, nor become experts in each stage. But, once someone becomes educated enough on the basics of what steps are required in another stage of the product manufacturing ecosystem, then they can show empathy for the persons performing those tasks, and they themselves can make better decisions to ensure the success of others.<\/p><p class=\"\">This is what DFX is about.\u00a0<strong><em>Making good design decisions so someone else (or thing) can do their job better<\/em><\/strong>. And the best way to make these decisions is to understand what tasks others will have to do when they receive the output of your work.<\/p><p class=\"\">DFx applies to all disciplines, not just electrical engineering, but to keep the talk succinct I focused only on DFx engineering for Printed Circuit Board Assemblies (PCBAs). Because electrical circuits can have 10\u2019s to 1000\u2019s of individual components assembled in very small and potentially complex networks of conductive traces, they inherently are complicated assemblies with the potential to incur very subtle defects.<\/p><p class=\"\">What can go wrong with assembling PCBAs? The list is not short, but for brevity I\u2019m highlighting the most common:<\/p><ul data-rte-list=\"default\"><li><p class=\"\">Insufficient or too much solder application resulting in electrical opens or shorts, respectively<\/p><\/li><li><p class=\"\">Poor soldering causing \u201ccold solder joints\u201d which in turn result in temporal electrical connections or joints which fatigue over time from prolonged use and exposure to various environments<\/p><\/li><li><p class=\"\">Counterfeit or damaged components which are not caught before being assembled<\/p><\/li><li><p class=\"\">Valid parts incorrectly assembled into the product<\/p><\/li><\/ul><p class=\"\">One can implement as many design decisions as they want to prevent these potential issues, but the only way to know if the choices are making an impact is to actually measure it. For manufacturing, that metric is called <strong><em>yield<\/em><\/strong>.<\/p><p class=\"\">Yield is a percentage of how many individual units in a production batch have passed all milestones and tests of the total batch size. Because of the potential complexity of products,\u00a0<em>and in my opinion PCBAs are the most complex<\/em>, there is no guarantee that you will have 100% yield. But, through smart prototyping and good implementation of DFx engineering guidelines you can certainly increase your chances to get as close as possible.<\/p><p class=\"\">The primary metric to use is called <a href=\"https:\/\/en.wikipedia.org\/wiki\/First_pass_yield\" target=\"_blank\" rel=\"noopener\"><strong><em>First Pass Yield<\/em><\/strong><\/a><strong><em>\u00a0(FPY)<\/em><\/strong>. This is the only way to compare apples-to-apples. Conceptually, an individual product which fails a test could be reworked once or several times until it finally passes the test. Since this is too variable, the safest metric to use is how many units pass on their first test attempt, without any need for reworking; hence the term: First Pass Yield.<\/p><p class=\"\">The goal is to achieve 97% FPY or better.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5935b4c elementor-widget elementor-widget-heading\" data-id=\"5935b4c\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Next we\u2019ll discuss how to achieve this by applying practical steps of DFX principles in your PCBA design.<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-215febaa post-text-block elementor-widget elementor-widget-text-editor\" data-id=\"215febaa\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p class=\"\">As previously discussed, there are many steps required to get a product ready for volume manufacturing.

As the PCBA travels past these heat sources, the solder will transform from its original paste-like state to a liquid state and then to its final solid state to hold all the components in place.\u00a0If the heating elements in the reflow oven are not tuned to the specific thermal profile of your PCBA, it will introduce the risk of components receiving too much or too little heat, which results in a low yield due to poor, or \u201ccold\u201d, solder joints.<\/p><p class=\"\">Even if the thermal pattern is correct, there are still only so many dials and knobs a technician can tune on a reflow oven. So, the majority of DFX efforts should be spent on the component selection and layout of the PCBA, itself. Here are some simple guidelines to help improve your PCBA layout:<\/p><ol data-rte-list=\"default\"><li><p class=\"\">As noted earlier, select a surface mount package for as many components as possible in your circuit. This allows for the highly automated and less variant processes associated with mounting and assembling these parts<\/p><\/li><li><p class=\"\">All items have mass, which when combined with the material type result in a specific required amount of applied heat in order for the item to reach the necessary temperatures for the solder to do its job. So, keeping this in mind, it\u2019s imperative to select components and create a layout on your PCB that generates a more uniform thermal profile, so all elements can easily reach their required temperatures.

Relying on people to setup and take test measurements is risky, horribly time inefficient, and expensive. Therefore, each manufacturing line needs one or more automated Functional Circuit Test (FCT) stages. This is the equipment that will test that each instance of your PCBA is assembled correctly and each function is working to its specification. The results of these tests contribute to the final First Pass Yield metric.<\/p><p class=\"\">A simple step to Design for Testing on your PCBA is to add explicit test points to facilitate the measurement of key signals and outputs of your circuit. All of these test points are to be located as close as possible to their associated source and placed exclusively on the bottom side of your PCBA. A corresponding custom test fixture, often referred to as a \u201cbed-of-nails\u201d is used to hold the PCBA under test in place. An array of electrically conductive pogo pins mounted in the test fixture make contact to the PCBA at the exact locations of the test points. These pogo pins are connected to the appropriate automated test equipment to make and record all of the test measurements. Software packages are used to customize and execute these tests, again removing the human element<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-73642f5 elementor-widget elementor-widget-image\" data-id=\"73642f5\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"500\" height=\"421\" src=\"https:\/\/durolabs.co\/wp-content\/uploads\/2016\/12\/pics.jpeg\" class=\"attachment-full size-full wp-image-2632\" alt=\"\" srcset=\"https:\/\/durolabs.co\/wp-content\/uploads\/2016\/12\/pics.jpeg 500w, https:\/\/durolabs.co\/wp-content\/uploads\/2016\/12\/pics-300x253.jpeg 300w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3df63c40 post-text-block elementor-widget elementor-widget-text-editor\" data-id=\"3df63c40\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\" image-block-outer-wrapper layout-caption-below design-layout-inline combination-animation-none individual-animation-none individual-text-animation-none \" data-test=\"image-block-inline-outer-wrapper\"><figure class=\" sqs-block-image-figure intrinsic \"><figcaption class=\"image-caption-wrapper\"><div class=\"image-caption\"><p class=\"\">Pogo Pins for an FCT \u201cbed-of-nails\u201d fixture<\/p><\/div><\/figcaption><\/figure><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-72019bd5 post-anchored-tag elementor-widget elementor-widget-heading\" data-id=\"72019bd5\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">GET OUT OF YOUR BUBBLE\n<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-747824cd post-text-block elementor-widget elementor-widget-text-editor\" data-id=\"747824cd\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"inner wysiwyg\" data-v-0163b48d=\"\"><p class=\"\">If there\u2019s one thing to take away from this article is to ensure you <strong>never design a product in a bubble<\/strong>.
