1. Place pinless header
2. With bottom of pc board
3. Apply an even, centered
over preinstalled posts
so that post tips start
into header cavities.
supported, place steel
block over header. Steel
block must be wider and
longer than header so
that it covers all four sides
of the header. However,
for headers with latches
pre-assembled, the steel
block must not interfere
with the latches.
force on steel block until
header bottoms on pc
board. If posts are
longer than .545 [13.84],
they may be forced
against the steel block
before the header is fully
seated. In this situation,
extreme caution must be
taken so that posts are
not damaged or pushed
out of the pc board.
