6.19 3D coplanarity laser module
Item no. 00119919-xx 3D coplanarity sensor
6.19.1 Safety instructions
The safety instructions are the same as described for the 2D coplanarity laser module in Section
6.18
, page 451.
6.19.2 Description
The 3D coplanarity laser module no longer works with a dot-shaped laser light source. It now re-
quires a laser light line. The measuring process is based on the principle of triangulation (see Fig.
6.18 - 2
, page 452). This makes it possible to generate and analyze a height profile for a two-di-
mensional arrangement of component connections, e.g. BGA, QFP, et. The analysis returns re-
sults for the coplanarity (placement plane) and colinearity (placement line) of component leads or
balls. The 3D coplanarity laser module can be installed on SIPLACE X2 and X3 placement ma-
chines.

6.19.4 Restrictions
– Lead or ball recognition can get worse if the surface is oxidized or glossy.
– The following components cannot be measured: a PLCC, SOJ, socket, chip, bare die,
Moulded, Melf, ECV, DPack, CCGA, screening plate, components which only have connec-
tions on the underside
6.19.5 Installation notes
Please note the following points if you are installing the 3D coplanarity laser module:
– The 3D coplanarity laser module can only be installed on SIPLACE machines that are
equipped with the A364 axis unit and the Box PC. It cannot be retrofitted on machines with
the A363 axis unit.

– Only one coplanarity laser module may be installed on each machine. The 3D coplanarity la-
ser module can therefore not be operated together with the previous module (see Section
6.18
, page 451).
– The 3D coplanarity laser module can only be installed at location 3.
– The 3D coplanarity laser module can only be used in conjunction with the TwinHead.
– The 3D coplanarity laser module cannot be set up if there is a Collect&Place head installed
in this placement area.
6.19.6 Analysis computer
A box PC acts as an analysis computer. It is housed together with the control computer and the
machine controller on the input side.
