It can be done. Not sure what machine you have, but the level for the
z-down distance can be changed so the centering jaws extend above the
vacuum nozzle, and you don't use the centering function. Then the part
is placed and you depend on the locater posts to align the component in
the pwb. The hole for the locater posts are designed with a diameter
.0012-.0015" larger than the posts, as the machine can usually always
hit that target, even without the centering function. The slop also
allows for the surface tension of the solder to align the connector
during reflow.
It is a difficult step to program on the Mydata, but it can be done.

Subject: [TN] Molex 52760-1609 160 Pin connector placement

Happy Holidays TechNet,

I need a little help,

Has anyone out there had recent experience with placing this part?

Molex 52760-1609 160 Pin connector 0.635mm pitch with a 58.67mm(2.309in)
overall length.

http://www.molex.com/product/micro/52760.html


It seems to be a little too large to fit in the centering jaws of our
Pick and Place machine... what other options are available if we don't
go back and redesign to change connectors?

Things that I am looking into are:
1) Can our machine shop modify the centering Jaws on the MyData machine
to fit the parts?
2)Does MyData sell a conversion or adapter to increase the Jaw area on
the machine?
3) Can we still insert the parts without having to go through the
centering jaws, perhaps with optical correction?
4) What does a new machine cost that will accept the part?
5) Other options?

What issues do you see with keeping the connector in the design? Any
good advice on how to proceed?

Best regards,

Bill Brooks
