5. This step is only reached by the "GO TO" Height Action from Step 2. It tests for a connector that
simply failed to reach MinFPP by the appropriate height, by checking for 250 Newtons force detected
within 0.1 mm below the MinFPP minimum height from Step 2. The speed will linearly slow to 2
mm/second by the target height.
6. This step checks for a missing connector if 250 Newtons force is not detected, even below the lowest
seated height. As soon as this level of force is detected, the process continues on the next line.
7. This line verifies the connector is pressed to within generally accepted height tolerance, and the
maximum force per pin is not exceeded.
8. This line gives a destination below the nominal seated height and terminates on the maximum force
per pin * # of pins. This variable here could also be "user force per pin" instead of MaxFPP, if a lower
repress force is desired. Final seating of a repress is generally done to a target force because the
initial position of a repress cannot be known. PARS termination cannot be used for a repress since
there often is no "pin penetration" force region to sample when the connector has previously been
partially pressed. While Force Gradient termination could be used with very rigid connectors and
PCB's (after reaching some minimum seating height and force), most connector represses apply
MaxFPP.
