If your product needs to perform specific functions when powered on, functional testing is the only way to verify real-world behavior before shipment.<\/p>\n<p>You may need functional testing if your PCB meets one or more of the following criteria:<\/p>\n<ul>\n<li>\n<p><strong>Contains firmware or software<\/strong> that runs on a microcontroller or processor<\/p>\n<\/li>\n<li>\n<p><strong>Interfaces with sensors, relays, motors, LEDs, or displays<\/strong><\/p>\n<\/li>\n<li>\n<p><strong>Communicates via protocols like UART, CAN, USB, I2C, or Ethernet<\/strong><\/p>\n<\/li>\n<li>\n<p><strong>Requires precise signal sequencing or conditional logic<\/strong><\/p>\n<\/li>\n<li>\n<p><strong>Needs to be powered on and respond to user inputs or test signals<\/strong><\/p>\n<\/li>\n<li>\n<p><strong>Must meet functional safety, reliability, or regulatory standards<\/strong><\/p>\n<\/li>\n<\/ul>\n<p>If your PCB is more than a passive circuit or basic power distribution board, functional testing is critical to ensure proper operation, avoid field failures, and reduce return rates.<\/p>\n<p>At Highleap, our engineering team can review your schematic or BOM to assess whether FCT is recommended, and if so, help you define the right scope and setup\u2014no guesswork required.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][et_pb_column type=&#8221;2_5&#8243;
