In the production of printed circuit boards (PCBs), In-Circuit Testing (ICT) is one of the most widely used methods to ensure electrical functionality<\/strong>. This testing relies on fixtures known as \u201cbeds of nails,\u201d where hundreds or even thousands of spring-loaded probes must make precise mechanical contact with the designated test points<\/strong> on the PCB.<\/p>\n

Even small misalignments can have serious consequences. If a probe misses the intended test point, measurements may not reflect the true condition of the circuit, leading to false positives (defective boards incorrectly validated) or false negatives (good boards rejected). Both outcomes are costly: the former risks product failures downstream, while the latter introduces unnecessary rework and waste. Repeated misalignment can also damage pads and shorten PCB lifespan.<\/p>\n

To mitigate these risks, manufacturers conduct conformity checks on ICT fixtures<\/strong>. However, in most facilities this process is still highly manual: operators inspect probe alignment under microscopes, often checking only a sample of test points. With hundreds of pads per PCB, this approach is slow, labor-intensive, and prone to variability, <\/strong>allowing minor misalignments to escape detection.<\/p>\n

As PCB complexity increases and production volumes grow, ensuring a reliable, efficient, and scalable method for probe alignment verification has become a critical requirement<\/strong> in modern electronics manufacturing.<\/p>\n[\/vc_column_text][image_with_animation image_url=”36126″ image_size=”full” animation_type=”entrance” animation=”None” animation_movement_type=”transform_y” hover_animation=”none” alignment=”center” border_radius=”10px” box_shadow=”none” image_loading=”default” max_width=”100%” max_width_mobile=”default”][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” equal_height=”yes” content_placement=”middle” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” top_padding=”48px” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” gradient_type=”default” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][vc_custom_heading text=”The Technology” font_container=”tag:h2|font_size:40|text_align:left|color:%23bfbfbf|line_height:50px” use_theme_fonts=”yes”][vc_custom_heading text=”Automation, AI, and Precision Mechanics” font_container=”tag:h3|text_align:left” use_theme_fonts=”yes”][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” equal_height=”yes” content_placement=”middle” 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” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” gradient_type=”default” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”2\/3″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][vc_column_text]\n

The key to reliable ICT lies in accurate probe-to-test-point alignment<\/strong>. Automated approaches replace subjective manual inspection with computer vision, artificial intelligence (AI), and precision mechanics<\/strong>, achieving micrometer-level accuracy.<\/p>\n

High-resolution imaging captures each pad, often less than 1 mm in diameter, and detects punctures as small as 25 \u00b5m<\/strong>. AI algorithms then analyze these images, distinguishing acceptable contact marks from problematic misalignments, while calculating exact deviations from the pad\u2019s center<\/strong>.<\/p>\n[\/vc_column_text][\/vc_column][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/3″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][nectar_image_comparison image_url=”36107″ image_2_url=”36111″][vc_column_text]\n
