Nick: I got two choices for ya: 1 Call your supplier, have 'em send ya an outline drawing, and read the pitch from the drawing. 2 Buy a vernier caliper and measure the center to center spacing of the leads. Good luck

| I was wondering what measurements are used to define pitch? Generally we would use it for the distance from lead center to lead center of an IC. For instance, an SOIC would usually have a pitch of 0.050" or 50 thousandths of an inch (1.27mm)|

that depends on clinch direction, length, and angle. .200" hole center to center is usually safe for all automatic insertion equipment.

Is an RQFP a Qfp with the center pad for heat dissipation? If so, you may be shifting when this center pad reflows and lifts the part.

Does any one know how far left or right from center the aperatures can be? If I had a 6" board, and a stencil with cut-outs for both sides right and left of center, would I have problems?

I forgot to ask if anyone knows what numbers I should get for function 30, nozzle height and center of rotation? I'm getting 365 for height and 12314 for center of rotation. I know it isn't 12.314 inches out!

Found the problem. A small part had previously fallen off the nozzle, and ended up behind the left centering jaw preventing the jaw from opening up fully. Cheers Darren

Hello Steve, i think you are experiencing the potato chip effect, where temperature difference at the center and edges are huge; causing BGA edges to tilt down or up.Try narrow down the temperature difference between the center of BGA and corner. I
