.130” pro le and will accept Ø.030” round pin,
as well as industry standard .025” square pin
headers.
They are typically used to interconnect two or
more parallel circuit boards.
Sockets are designed for hand, wave or re ow*
soldering. The high temperature insulator is
compatible with all solder processes.
Unique ORGANIC FIBRE PLUG® barriers prevent
solder, paste or ux from contaminating the
internal spring contacts. After soldering, the
OFP® barriers are pushed out of the socket when
the mating header is inserted.
Mill-Max sockets use a receptacle consisting of a
precision-machined brass sleeve with a press- t
beryllium copper “multi- nger” spring contact.
Recommended mounting holes are Ø.046 ±.003”
PTH (1,2 mm drilled prior to plating).

*Intrusive
reflow (also called “pin-in-paste”) is a technique
of using conventional through-hole components in a
reflow soldering process. The pass-through socket is placed
into plated through-holes in the circuit board (solder paste
has previously been screen printed on pads adjacent to the
holes) and the board is reflowed in the same pass as other
SMT components. Solder will fill the plated through-holes
and achieve solder joints as reliable as wave soldering. The
OFP® barrier prevents solder paste from being picked up
inside the contact during assembly.
