You can use below code in php to check the checked box values using array and try to insert inside foreach with that particular id

$id= 'Your_id';
if(!empty($_POST['secondtechno'])) {
    foreach($_POST['secondtechno'] as $check) {
            //echo $check;
            //$sql = "INSERT INTO YourTable(id, columnname)VALUES ('".$id."', '".$check."')";
    }
}
