Place it as a square. Vision type 10. Why would you even try to inspect leads on this? It's not like they could get bent.

Hi,

Thats the way I have been placing it but we have seen a few misplacements failing in test and I am trying to improve the placement accuracy and consistency by locating the leads/pads .

Using the 120,121,122 series is what you should try first frontlighting. The P Pattern will probably be "4". If this does not work, blacken the background disk (paint) and then use vision type 124. This will give you a great image if the 120 series does not work out.
