Mill-Max Solder Pre-forms
Mill-Max now offers solder pre-forms.
Solder pre-forms enhance the assembly
of large pin grid array (PGA) sockets.
The main benefit of solder pre-forms is
the placement of solder directly between
the lead and the hole. This ensures a
good solder joint.
Solder pre-forms allow our customers to
attach thru-hole devices onto a board
soldered using reflow methods. This
allows for mixed technology boards.
The solder pre-form is 63% tin and 37%
lead.
All Mill-Max sockets use precision machined pins which eliminate any possibility of solder wicking
or flux contamination. Press-fit into each pin receptacle is a low force beryllium copper multi-finger
contact renowned for greater compliancy and proven reliability.
See the reverse side for an example of a typical PGA with solder pre-forms.
