Description

In addition to correct positioning,

placement reliability is important.

On the SIPLACE S-25 HM this is

ensured through a number of con-

trol functions, such as vacuum

checks and component vision

testing during the placement se-

quence.

Out of tolerance components are

rejected, placed on the repair list

and automatically processed dur-

ing a repair cycle. An offset in the

position of the PCB relative to the

conveyor system (PCB vision) and

an offset of the X-axis, Y-axis or ro-

tation of the component relative to

the midpoint of the nozzle (com-

ponent vision) trigger an immedi-

ate correction to ensure placement

accuracy.

Since the PCB is fixed, the com-

ponents remain in the exact posi-

tion they are placed. The stationary

component table ensures a pre-

cise pick up. Options, such as the

component bar code scanner, can

be added to further enhance reli-

ability.

Placement errors

Placement errorsPlacement errors

Placement errors

Errors that occur after the compo-

nent has been placed on the PCB.

They include:

§ Component is missed on PCB

§ Too many components on PCB

§ Components not placed prop-

erly on PCB

§ Components placed while

standing on edge

Description

Despite the highly stable machine

frame, slight distortions of the gan-

try axes cannot always be avoided.

With the aid of the mapping proc-

ess the high placement accuracy

of the machine is preserved

throughout its entire service life.

With this calibrating procedure,

which can be conducted quickly

and easily, the PCB camera recog-

nizes the fiducials on a mapping

calibration plate placed in its oper-

ating area. Any distortions are re-

vealed by comparing the nominal

grid on the glass plate with the ac-

tual grid “drawn” by placement

head. These distortions are taken

into account during all further posi-

tioning of X-/Y-axes and thus com-

pensated for.

Description

SIPLACE Pro is the programming

software for all SIPLACE place-

ment machines and placement

lines. It is designed to support the

stand alone capability, Siemens

line configuration and the seam-

less integration into a CIM envi-

ronment.

SIPLACE Pro is a client/server

software system that delivers out-

standing PCB programming per-

formance. It consists of the

SIPLACE Pro Server and Database

for centralized storing of all placing

programs in use and the SIPLACE

Pro Desk to assist all day to day in-

teractions with SIPLACE place-

ment machines.

SIPLACE Pro runs on standard

hardware (PC). It is based on Win-

dows NT with tree controls, drag

and drop as well as all standard

Windows NT features.

It works directly on the placement

system itself for operator interac-

tion, or any PC – standing alone or

connected to the LAN of the

SIPLACE line. SIPLACE Pro has

features for monitoring, program-

ming, line balancing and set-up

optimization. Thus a separate line

computer is no longer necessary.

But for offline programming the

SIPLACE Pro software can be run

on a separate standard PC as well.

With its powerful and enhanced

graphical user interface SIPLACE

Pro offers programmers and day

to day users
