4. Features

a. The LS 3000 is the newest, cost effective, optical inspection system

specifically designed for today’s electronics. It’s primary use is for

inspection of area array devices including PBGA’s, CSP’s, Flip

Chips, LBGA’s, CBGA’s etc. However, the LS 3000 has a wide

range of other inspection used on any SMT or through-hole base

PCB. The LS 3000 is ideal for periodically monitoring the

performance of production or rework reflow equipment. It is also a

critical inspection/monitoring instrument for R&D labs and process

development departments when developing new processes of

troubleshooting problems.
b. The LS 3000 features a high resolution CCD chip camera and

incorporates industrial quality endoscopic components to acquire

images. The video signal can be sent to a stand-alone monitor or

can be routed to a PC via a video acquisition card. The system

comes standard with front lighting through the endoscope and with

back lighting from one fiber light gooseneck and one end piece.

Both back and front lighting can be adjusted independently. An

optional dual gooseneck for back lighting is also available. The

camera head on the LS 3000 can be moved in the Y direction using

a fine adjustment knob on the side of the system, which allows the

user to scan an entire side of a device with ease.
c. The LS 3000 verifies your process integrity so you can have

absolute confidence in your production or rework process.

5. Un-packing

Your LS 3000 system comes completely contained in one cardboard box,
which has been secured to a shipping palette. If you have purchased the
optional monitor, it will come packaged in it’s own box and will be attached
to the top of the system box.

www.paceworldwide.com Page 4 of 20

System Operations Manual, Rev A

Starting with the LS 3000 container, please use the following steps to
safely unpack;

a. If your system came with the monitor, cut or loosen any straps,

which hold the monitor box to the main assembly box. Set monitor

box aside.
b. The cardboard box holding your LS 3000 will come strapped to a

palette. This can be left intact or the straps holding it to the palette

can be removed and the box removed from the palette.
c. Carefully cut any tape holding the main assembly box top together

and open the box top.
d. The interior of the box contains several, custom cut, foam packing

trays. The top packing tray will have a set of Velcro straps running

though it.
e. Un-do the Velcro straps as shown in figure 2 and carefully remove

the top foam-packing tray. This will reveal the camera head

assembly, which has been removed from the main system for

shipping.

Figure 2 Und oing the Velcro Straps

f. The camera head assembly is still connected to the main unit via

it’s wiring which will be clearly seen. Carefully lift the camera head

assembly without placing any strain on the wiring and remove the

second foam-packing tray as shown in figure 3. This is the packing

tray that previously cradled the camera head assembly.

your LS 3000 system.

a. Place your LS 3000 system on a sturdy, firm surface. Ensure the

surface has enough space to support the four legs under the

system.
b. Ensure the system sits level on its bench. If it does not, the four

individual legs can be adjusted as show using a medium sized

adjustable wrench.
c. Locate the main power cord in the accessories kit.
d. Attach the main power cord to the rear of the unit as shown in

figure 6. Do not turn on main power at this time.

EXTREME CARE WHILE HANDLING AND USING

g. Using the Fine Height adjustment as shown in figure 15 and while

adjusting the position of the PCB Manipulator, position the Rigid

Probe so that it is along the side of the component to be inspected.

10. Maintenance

a. The following procedures should be followed in order to periodically

check and inspect your LS 3000 system. Anything beyond normal

cleaning and checkup should be referred to a qualified PACE

service technician.

i. Periodically inspect the main power cord for signs of wear or

damage. If wear or damage is found, replace the cord
immediately.

ii. You may clean the rigid probe assembly with a soft cloth.

Do not use any type of cleaner for this process as damage to
the probe may occur. If the image seen with the rigid probe
is not clear and crisp, contact your local PACE
Representative

iii. The plastic fiber probe can be trimmed should the ends

become frayed or damaged. Trimming can be accomplished
by carefully using a razor knife and cutting all fibers to the
same length. Eventually the plastic fiber probe will need to
be replaced.

iv. The main tray and work surface can be periodically wiped

clean with a soft damp cloth. Avoid cleaning chemicals.
