Look like I am going to hand pick and place a fine pitch device for
prototype.  Does anyone can recommend me a "manual vacuum hand pick pen"?
The requirements are:
(1) handle large components, such as 45 to 60 mm square with body weight of
300 to 500g (top of the body would be either moulding epoxy or metal
lid-hybrid).
(2) vacuum pick and hold for 5 min. solid (no dropping).
(3) predictable release time (control release speed if it is possible).
(4) not too heavy (can handle with one hand - I need the other hand to focus
the microscope).
I found Pac-Vac pen...It looks good with pager size motor...Any experienced
comment?
Current vacuum pen we have can only pick up the CPGA for 20 sec.  With my
aging eye sight, it is almost impossible for me to focus and coordinate all
my limbs into smooth action within 20 sec.
Many thanks in advance.
