834/835 Series Pass Through Sockets have a
low 3,30 profile and will accept 0,76 round
pin, as well as industry standard 0,64 square
pin headers.
They are typically used to interconnect two or
more parallel circuit boards.
Sockets are designed for hand, wave or reflow*
soldering. The high temp. insulator is compati-
ble with all solder processes.
Unique ORGANIC FIBRE PLUG barriers pre-
vent solder, paste or flux 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 precision-machined
brass sleeve with a press-fit beryllium copper
“multi-finger” spring contact.
Recommended mounting holes are 1,17
±0,08 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 solder-
ing. The OFP barrier prevents solder paste from
being picked-up inside the contact during assembly.
