Several core elements you must know for purchasing machines
The Most Essential Elements of A
Qualified Pick and Place Machine
Before purchasing a machine,
we must carry out a reasonable ap-
praisal and consideration of the
most essential performance. The
quality and price varies vastly due
to the multiple brands,so customers
can't even figure out how to choose
one which is most suitable for him-s
elf. And it is very necessary for you
to make full preparation before pur-
chasing.
Then how can we choose a mac
-hine suitable for ourselves?
The resistor and capacitor above 0402 can not
represent the accuracy of the machine. The mou
nting accuracy and repeated mounting accuracy
referred mean whether the precision chip with
the lead pitch of 0.3mm can be accurately mou-
nted. And the process can be completed without
a second adjustment in a row for ten times.
The degree of manual involvement in the proce-
ss of programming is less than 15%, most of the
work is undertaken by the software part of the m
achine and completed automatically.
After adjusting the program, the rate of finished
products is higher than 99.5% under the conditi-
on of continuous 24-hour mounting.
It refers to the mounting efficiency of the equip-
ment per hour,namely the number of compone-
nts to mount in unit time under the premise of e
nsuring the stability,for example, with stopwat-c
h timing, the mounting efficiency of the machi-n
e is 100 / 25 * 3600 = 14400 pc/h based on the
calculation of 25 seconds for 100 pieces.
