What is the best shape of fudicials relative to size and configuration? Also
if the board has HASL on all of the pads, can the fudicials be of different
material other than HASL? We are having a problem with reflective light
causing a lot of rejected boards. This is also causing down time. What is
the industry using for this technolgy. We have DEK 265 printers and Philips
and Siemens placement machines.
