STAGGERED GRID DESCRIPTION<br />
The <strong>LRM</strong> standard staggered grid pattern<br />
employs surface mount leads on .025 inch<br />
centerlines (pitch). Insert patterns of digital<br />
brush contacts are in 80, 108, 152 and 180<br />
contact counts. See typical arrangement<br />
drawings on pages 19 and 20.<br />

STAGGERED AIRFLOW-THRU GRID<br />
DESCRIPTION<br />
The staggered grid airflow-thru inserts were<br />
designed to accommodate wider board<br />
packaging and airflow-thru heatsinks. Insert<br />
patterns of digital brush contacts are same<br />
as the staggered grid pattern (80, 108, 152<br />
and 180 contact counts). See typical<br />
arrangement drawings on page 21.<br />
