Hi Brian- All is well on my end. I have not been to SMTNET in a long while but pop in from time to time. Working here at Agilent gives me more of an opportunity to check in. How are things on your end? Where are you working these days? Cal

| What allowances are people using out there for components off-pad, we currently use 50% of lead width without breaking trace/component clearances but we have a customer demanding 25% allowance ? | IPC states: 50% off pad for class 1 and 2 25% off

Unless you have a firm grasp on the circuit and electronics in general, you are on a hiding to nothing. Testing components in circuit is complex, because its a circuit and any measurement you make is affected by connected neighboring ones. If you set

One other thing to check is your PEC camera. Universal uses a jig to calibrate this camera but you could check it using this method. 1.Run about ten 0402 parts on tape with the PEC camera off and check placement. If the placement is off change the x\

Does anyone have any off-the-shelf tool for measuring air gaps under components? Specifically to measure if a part is raised beyond special specifications, such as determining if a leaded connector is raised beyond 5, 10 or 20 mils from the PCB surf

What exactly do you mean by component shifting? If you mean lead over hang, i.e, how far off the pad can a component lead sit and still be acceptable, IPC 610 addresses this.
