So here it is, your quick guide to First Pass Yield.<\/span><\/p>\n

First Pass Yield really isn\u2019t that complicated, but many businesses, particularly those with in-house testing solutions, fail to calculate it properly. As we\u2019ll get into today, this can be very costly to electronics manufacturers because issues in testing can quickly snowball if missed.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” column_link_target=”_self” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid” bg_image_animation=”none”][vc_column_text]\n

What Is First Pass Yield?<\/h2>\n

First Pass Yield (FPY) is a term you\u2019ve probably heard at some point in the electronics industry, but maybe under a name like Throughput Yield or Output Yield. These terms confuse the real definition, so from now on \u2013 call it First Pass Yield. It refers to how many units of a product are tested successfully in a test process, compared with how many products went through that process. And importantly how many went through the first time!<\/p>\n

The last part of that definition is very important and usually, the thing that manufacturers miss when they calculate FPY themselves. FPY needs to take into account every test failure that occurs, including retests on a unit that is made good following a failure. Also, the FPY value should be unique to each individual testing operation that you are carrying out on a manufactured product.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” column_link_target=”_self” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid” bg_image_animation=”none”][vc_column_text]\n

Why First Pass Yield Is So Important<\/h2>\n

FPY is a great way of determining wastage in your manufacturing process. That’s wastage stemming from failed production which impacts profitability and productivity with extra materials, machine time, and operator resources needed to hit your targets.<\/p>\n

But there are a host of other benefits to testing FPY properly, including:<\/p>\n
